1.2 Content and target group of this manual
This manual contains information on the host connection (BS2000, MVS/ESA, Linux, UNIX,
Windows...) of ETERNUS CS HE.
●
It provides information for host system administrators about the settings needed to
connect their systems (BS2000, MVS/ESA, Linux UNIX, Windows...) to ETERNUS CS
HE.
●
There is advice for setting up libraries which can work both as a back end with
ETERNUS CS HE or directly with the host.
●
It shows the zoning of an FC switch which can be switched between the host und
ETERNUS CS HE.
●
It shows ETERNUS CS HE service personnel how ETERNUS CS HE should be
configured for connection to each of the host systems indicated.
Only the maintenance technicians who have the ETERNUS CS HE root and service
passwords can access and edit ETERNUS CS HE configurations. The ETERNUS CS HE
configuration is described in the maintenance manual [2]. The configuration set up in
ETERNUS CS HE is displayed on the graphical interface. It can also be output from the
graphical interface in various ways and displayed as a list. The relevant details can be found
in the graphical interface manuals.
1.3 Concept of the manual
This manual is a supplement to the user and maintenance manual. The installation instructions are divided as follows:
1. General operating procedures and summary tables (system independent).
2. Connecting ETERNUS CS HE to host systems, divided by system (BS2000, MVS/ESA,
UNIX-type systems, and Windows).
3. Tape management systems (NetWorker,..Tivoli), divided by management system. Each
section contains an appendix detailing the operating-system specific features.
4. Practical instructions such as:
– Useful commands for UNIX systems.
– Instructions on accessing ETERNUS CS HE configuration data
– Using libraries
– Setting FC switches
– Host Bus Adapter
– Configuration example for ETERNUS CS HE (adding an ICP)

Introduction
1.4 Notes
General
ETERNUS CS is subject to constant development. The information contained in this
manual is subject to change without notice.
Changed company name
On April 1, 2009, Fujitsu became the sole owner of Fujitsu Siemens Computers. This new subsidiary of Fujitsu has been renamed Fujitsu Technology Solutions.

Introduction
Preparatory considerations
1.5 Preparatory considerations
The ETERNUS CS HE front end, depending on the configuration setup, can emulate
several robot systems (connected via TCP/IP LAN) and tape drives (connected via ESCON
or fibre channel). This is independent of which real robot systems and which drives are
actually connected to ETERNUS CS HE (back end). Details on the emulations which can
be set, and the real devices which can be connected can be found in the data sheet of your
ETERNUS CS HE.
The logical volumes of ETERNUS CS HE can be easily distinguished from real volumes.
They do not belong to a logical library and are not therefore assigned to any drive type. Thus
they can be mounted in practically all drive emulations configured in ETERNUS CS HE; the
only limitations here are those deriving from the type of backup tool (e.g. NetWorker) used.
The name of a volume must, therefore, be unique for the whole ETERNUS CS HE.
In many cases, ETERNUS CS HE is integrated into an existing host system with backup
and tape management system. Tape libraries may already be present, which can be linked
directly with the host, or as a back end with ETERNUS CS HE.
The following rules apply here:
Real drives
cannot be used jointly
Physical tape cartridge drives cannot be used jointly
Robots
can be used jointly if the robot controller supports this
The figure below shows which host components handle the various items of configuration
data in the ETERNUS CS HE.
The procedure to be followed depends on the system. Lines written in bold apply to Open
Systems and BS2000 on FC (SX and S Server), lines written in italics apply to MVS/ESA
and BS2000/OSD.

Introduction
The following tests and settings should be made before the starting configuration work.
●
ETERNUS CS HE can emulate various tape cartridge drives. This manual indicates
which drive types can be used with your system, and provides instructions on how to
create device nodes with the necessary properties.
We recommend that you use the emulations given in these instructions. Fujitsu has
carried out extensive testing precisely for this configuration.
●
Individual management systems (e.g. NetWorker, Tivoli,...) only support particular
types of library and drive. Before you start, you should note which library your tape
management system can operate and then configure ETERNUS CS HE accordingly. In
order to ensure trouble-free operation, the configuration in ETERNUS CS HE must
match the host configuration exactly.
●
Cases where several hosts are to be connected to ETERNUS CS HE. In these cases
you should first establish if and how virtual volumes and drives will be separated from
each other in the emulated libraries, and then set the emulations accordingly.
●
Set the number and allocation of the virtual drives.
You should take steps to ensure that any virtual drive in an open system is connected
precisely to one FC adapter only.
i
Take note of the maximum throughput of the available FC connections. If this
limit is exceeded, the performance of the fibre channel may fall dramatically.
If real libraries of ETERNUS CS HE and the hosts are to be used jointly, set how the
drives and storage areas are divided.
This division and the cabling of the library and the drives with ETERNUS CS HE must
be completed before ETERNUS CS HE is configured.
●
Establish how the cleaning of the drives is carried out. ETERNUS CS HE can take over
the cleaning of the drives assigned to it, including the administration of the cleaning
cartridges. Not all libraries, however, allow the drive specific administration of cleaning.
●
You should check, which host adapter types are in use with your system on ETERNUS
CS HE. Make sure that up-to-date FW drivers are installed. You should check
compliance with these requirements and implement them where necessary, before
starting any integration work.
i
The chapter “Useful commands and information” on page 395 shows how you can
find the current configuration data of the ETERNUS CS HE on the graphical user
interface.

Restrictions for server farms using Open Systems
Summary of permitted configurations
2.5 Restrictions for server farms using Open Systems
In principle all Open System hosts should be able work with an ETERNUS CS HE via a
fabric.
However, given the wide variety of FC controller hardware and the large number of
operating systems involved, problems can occur. This section provides a quick guide to the
problems which may arise and suggests some solutions.
The following problems are known:
Solaris scans all LUNs and as a consequence sporadically disturbs the data transfers
of other systems.
●
Troubleshooting: see section “Solaris systems in server farms” on page 167.
2.6 General information on Open Systems
As of version CS V3.0 fixed block length mode is supported in VTD emulation.
This applies for all 3 emulation types:
–
–
–
FSC generic
EXABYTE Mammoth2
IBM 3590E
As a result, BrightStor ARCserve backup can, for example, be supported on Windows. For
releases see the section “Configurations with ETERNUS CS HE in the SAN environment”
on page 23.
24
i
The variable or fixed block length mode is not configured on the ETERNUS CS HE
user interface, but is defined internally by the application on the host.
!
CAUTION!
The pro-FC port resources currently suffice for 64 x 256-MB I/Os in parallel (256 MB
is the maximum variable block length). If fixed block length is used the size of
maximum block length may be increased, however only at the cost of the number of
emulations, i.e. if 2-MB fixed block I/Os are used the maximum number of emulations that can be used in parallel is 8 ( i.e. 64 * 256/2048 ).
3 ETERNUS CS HE in BS2000/OSD
3.1 Miscellaneous
When ETERNUS CS HE is operated in BS2000/OSD the large number of virtual drives
means that the number of mount messages can increase. To prevent message queues at
the console in unattended mode when NBLOGENF=Y is set to specify audit-standard
console logging, the system administrator must ensure that enough space is always
available on the home pubset for the CONSLOG files.
In addition, the time for buffering messages with BCAM should not be restricted with
/BCTIMES LETT=... .
Because there is no option for controlling the library in offline mode (without ROBAR/CSC),
no SLED is possible for ETERNUS CS HE either on the ESCON or on the FC channel. Nor
is initial installation by FIRST or SIROS or physical backup with offline FDDRL supported.
3.1.1 Asynchronous tape processing with SYNC
In the case of asynchronous tape processing, e.g. by means of BTAM (cf. BS2000/OSD-BC
User Guide, DVS Assembler interface), the data is initially buffered in a device-specific
buffer and written to tape only when a specific buffer utilization level is reached. As a result,
in some circumstances not all data will really have been written to tape when hardware or
software faults occur. Only when the CLOSE command has been positively acknowledged
is it guaranteed that all data has been stored consistently on the volume.
As the buffer utilization level is device-specific, it cannot be assumed that the buffer content
is transferred to the tape during processing after a particular amount of data has been
exceeded. However, calling the SYNC command enables a consistent status to be ensured
section by section while asynchronous tape processing is in progress.
Basically the use of ETERNUS CS HE in no way alters this fact. However, as the buffers are
very large here, it can occur that when an error occurs considerably more data has not yet
been written to tape than in real mode. Only afer CLOSE or SYNC has been acknowledged
positively does ETERNUS CS HE naturally also ensure that a consistent saved status has
been achieved.
25
Miscellaneous
ETERNUS CS HE in BS2000/OSD
Products such as HSMS or ARCHIVE secure asynchronous tape processing by calling the
SYNC command. This is also required in customers’ own applications and programs.
3.1.2 Configuration of logical drives in BS2000
The configuration of virtual ETERNUS CS HE drives is practically identical to the configuration of 36-track drives in ABBA or STK robots.
For the instances given below of MAREN, NDM and ROBAR or CSC you must define an
identical, freely selectable storage location with a maximum of 5 characters (e.g. CEST1).
The steps necessary for the different instances are shown in the following example:
3.1.3 Activities in UGEN
i
Each ICP is an independent control unit in BS2000 on the ESCON channel and can
thus be configured using 2 or 4 paths in the direct connection. The address area
always begins with null.
1. Create an input file for UGEN (for details, see the system installation manual [8] of the
BS2000 version you are using):
Example:
Task:
Generation with two ICPs, each with 2 ESCON controllers, where all
virtual drives are connected via ESCON using two paths. These two
paths correspond to the two ESCON channels on each ICP.
i
26
BS2000 supports configurations using a maximum of 8
paths. However, only 4 ESCON channels can be connected
to one ICP.

3.1.4 Activities in MAREN
●
Version < V10
1. Use the following MARENADM instruction to define the storage location for the
ETERNUS CS HE logical volumes:
//MODIFY-MAREN-PARAMETER LOCATION = *PAR(LOC-NAME = CEST1,
ACTION = *ADD)
2. Terminate MARENCP (MARENADM instruction):
//STOP-CONTROL-PROG MARENCP
3. Enter the following line in the MARENCP-ENTER file:
LOCATION CEST1,LOCAL,ROBAR-2
i
The new ROBAR-2 operand is required to indicate the operating mode for the
ETERNUS CS HE system in MAREN.
4. Next, restart MARENCP.
28
●
Miscellaneous
Version >= V10
Parameters which are local on a computer or global which were previously defined
when the MARENCP procedure was started have no effect in MAREN V10.0A and
higher. They are grouped together as computer-specific functions.
Only after the MARENCP task has been started for the first time during the BS2000 sysstem run can the MAREN subsystem become active. Before this point, tape processing
is rejected in the case of dialog tasks; in the case of batch tasks an operator input is
requested. Consequently, when a system is started up using suitable startup procedures, it must be ensured that the control program and the MAREN subsystem are already
loaded when a session is opened.
The storage location for the logical volumes of ETERNUS CS HE is defined with the following MARENADM statement:
//MODIFY-MAREN-PARAMETER LOCATION-ENTRIES = *PAR(LOC-NAME = CEST1,
ACTION = *ADD(OPERATING-MODE=*ROBAR2))
The original file $SYSMAREN.SYSENT.MAREN.100.SPD.MARENCP can be used for
startup.
When you connect ETERNUS CS HE to an STK robot system and some of the STK drives
continue to be used as native TAPE-C4 devices, you should note the following:
The storage location of the volumes used as real native (not to be confused with the tape
volumes used by ETERNUS CS HE for making physical backups) is not defined in MAREN
as a robot storage location (operating mode for the real STK robots in MAREN is EXTERNAL
and not ROBAR-1). Because MAREN tries to handle free tape requests using volumes from
a robot storage location, when ETERNUS CS HE is implemented the virtual volumes will
be assigned as free tapes by default.
To prevent this, you will need to use a MARENLM reservation file or make use of MAREN
exits.
Here is an example:
The real volumes in the STK robot system are still to be used with the MAREN storage
location STK1 for the free tape requests. Only jobs that have the job name CESTTEST are to
be assigned free tapes by MARENUCP from the virtual volumes entered in the MAREN
storage location CEST1.
MARENLM is used to take the following records from the MAREN reservation file (only
relevant fields are mentioned):
Location
Volume type
Job name
CEST1
TAPE-C4
CESTTEST
STK1

1. Including logical volumes in the MAREN catalog:
Case 1:
Logical volumes are added to the MAREN catalog using the following MARENADM
statement:
//ADD-FREE-VOLUMES VOL=..., FREE-LOCATION=CEST1, DEVICE-TYPE=TAPE-C4
Separate modification of TEMP-LOC is not necessary here. In the case of ETERNUS
CS HE tapes, MAREN supplies all three locations (HOME-LOC, FREE-LOC and
TEMP-LOC) with the same value specified in FREE-LOCATION when //ADD-FREEVOL is executed (in contrast to TLS locations, for exmple).
Case 2:
If a logical volume is to be reserved for a particular user ID as soon as it is included in
the MAREN catalog, the following statement is used:
//ADD-RESERVED-VOLUME VOLUME=..., LOCATION=*PAR(HOME-LOC=CEST1,
FREE-LOC=CEST1, TEMP-LOC=CEST1), DEVICE-TYPE=TAPE-C4, USER-ID=...
2. Initializing the logical volumes:
The logical volumes can be initialized only when the corresponding preparations have
been completed in NDM and ROBAR (in the event of a host connection via ROBAR).
Before they are used for the first time all virtual volumes must be initialized. The
following MARENADM statement is used for this purpose:
//INIT-VOLUMES VOL=..., NEW-VOLUMES=*YES
Alternately the virtual volumes can be initialized with the BS2000 utility routine INIT. The
statement used for this is:
INIT TAPE-C4,VSN=...,NEW
The simplest way to include and initialize a number range of free volumes is to use the
following sequence of MARENADM statements:
//ADD-FREE-VOL VOL=*INT(FROM=<vsn1>,TO=<vsn2>),FREE-LOC=CEST1,
DEV-TYPE=TAPE-C4,INIT=*YES
//FREE-VOL VOL=*INT(FROM=<vsn1>,TO=<vsn2>),INIT-FILE=MARENADM.INITFILE(INIT- LOC=CEST1)
//INIT-VOL INIT-LOC=CEST1, ... ,NEW-VOL=*YES
The following message is output on the console for each released virtual volume:
MARM1S1 SET VIRTUAL VOLUME '<vsn>' OF SYSTEM '<location>' AS FAST MOUNT.
REPLY (0=OK; 1=NOK)
31
Miscellaneous
This message is answered by ROBAR or CSC.
When the virtual volumes are released the data on them is deleted irrevocably. Only the
tape labels are retained.
The location name for the virtual volumes must be specified in the INIT-VOL statement.
The following message is output by MAREN during the initialization run for virtual
volumes:
MARM1IB MOUNT VOLUME ''<vsn>' ON DEVICE '<device>' FROM ROBOT
'<location>''?
Further special aspects for logical volumes in MAREN:
–
Exporting by means of //EXPORT-VOLUME not allowed.
–
No relocation possible using //RETURN-VOLUMES.
–
Modification of HOME-, FREE- or TEMP-LOCATION via //MOD-VOL-ATTR is
rejected.
–
Deletion not possible using //REMOVE-USER-VOLUMES.
Virtual volumes must be released for deletion using //FREE-VOLUMES and then be
deleted using //REM-FREE-VOLUMES. Only the MAREN catalog entry is removed.
The logical volumes must then be deleted in ETERNUS CS HE using the GXCC
function.
Release run
In the MAREN release run all the released logical volumes are set to "migrated" provided
they are still in the cache. In a subsequent MAREN initialization run, however, logical
volumes are not restored, but the stub of a volume which still exists in the cache is initialized. However, if these volumes are initialized via the BS2000 user program INIT or in the
context of a MAREN free tape request, a restore takes place, as a result of which these
tapes are mounted with a slight delay. You are therefore recommended to reinitialize
released volumes via MAREN.
If you want to prevent the logical volumes being set to "migrated" when the MAREN release
run takes place, the optional REP correction A0447567-012 must be used. This correction
suppresses the output of the message MARM1S1 'SET VIRTUAL VOLUME '(&00)' OF
SYSTEM '(&01)' AS FAST MOUNT. REPLY (0=OK; 1=NOK)' when the MAREN release run
takes place and thus also implicitly suppresses migration of these volumes.
You are advised to perform initialization of logical volumes using the MARENADM
statement INIT-VOL.
32
Miscellaneous
Reinitialization of virtual volumes using the MARENADM statement INIT-VOL VOL=<oldvsn>,NEW-VOL=<new- vsn> is not permitted. This corresponds to the procedure in the real
robot in which the barcode label does not change and the old real tape is therefore still
loaded into the drive.
33
Miscellaneous
3.1.6 Activities in NDM
For a full description, see the BS2000 manual on system support [3].
The virtual tape devices must be assigned to a device depot in NDM, where the name of
this device depot must be identical to the MAREN storage location1:
/ADD-DEVICE-DEPOT UNIT=(mn1,mn2 ... mnx), LOCATION=CEST1
In BS2000/OSD V4.0A it is possible to assign more than 128 tape drives to a device depot
when the optional REP correction A0460384-330 is used.
To guarantee smooth and high-performance tape operation, the following values should be
set using the BS2000/OSD command /MODIFY-MOUNT-PARAMETER:
/MOD-MOUNT-PAR PREMOUNT-MSG=*IGNORE-USER-REQUEST
This parameter causes the output of the PREMOUNT messages (NKVT012 PREMOUNT
TAPE '(&00)' ON DEVICE '(&01)') to be suppressed. This message is of no significance in
robot operation in that it is only answered with "tsn." by ROBAR but no reactions occur. If
tapes frequently need to be mounted manually on real drives outside the robot, it may be
advisable to retain the default value PREMOUNT-MSG=*ACCORDING-TO-USERREQUEST.
!
CAUTION: The procedure here is the same as that for a real robot. Virtual tape
operation with ETERNUS CS HE must be set with unconditional unloading of the
virtual volume. To do this, use the following command:
/MOD-MOUNT-PAR UNLOAD-REL-TAPE=
*REGARDLESS-OF-USER-REQUEST(TAPE-FAM=*MBK)
If long tapes are also to be dismounted after they have been used, the TAPE=*ALL
operand must be specified instead of TAPE=*MBK.
Restriction:
However, if operations take place on tape in a session with SPOOLOUT, this
parameter means that the SPOOLOUT tape must be dismounted and then
remounted after every SPOOLOUT of a file.
If several virtual drives are attached to a single BS2000, and these drives are located on
several ETERNUS CS HE ICPs, then in order to ensure that the load is spread equally
across the various ICPs it is necessary to set the following mount parameter.
/MOD-MOUNT-PAR NEXT-TAPE-MOUNT = *LEAST-RECENTLY-USED-DEVICE
1
If the list of devices contains more than 10 entries, you must use several commands.
34
Miscellaneous
3.1.7 Activities in ROBAR-CL and ROBAR-SV
These are necessary if an ADIC library is connected.
If the virtual connection to ETERNUS CS HE is made by an emulation of an ADIC library
(VAMU), the following settings for ETERNUS CS HE are necessary for the host connection
via ROBAR to the VAMU. ROBAR must be Version 3_0B or higher.
ROBAR-CL
The following settings are recommended for monitoring times (entered in the file
SYSPAR.ROBAR-CL.040.PROZPARAM):
VerbMonitoring=300
VerbMonitoringTime=180
From ROBAR 4.0 these are the standard specifications.
ROBAR-SV
If ETERNUS CS HE is connected to BS2000/OSD via ROBAR, the following preliminary
work is necessary:
●
ROBAR-SV must be reinstalled for ETERNUS CS HE operation. In this case the
ETERNUS-CS-HE-specific ROBAR Rule Files are read in.
●
If the ROBAR environment variable ROBAR-ARCHIV is set (see ROBAR menu item
DEFINES ➟ PROFILE), the VSNs of the logical volumes must be included in this.
Example
ROBAR_ARCHIV=LV0000-LV9999
export ROBAR_ARCHIV
●
The addressing mode robot_devid=EXPLICIT must be set for the virtual devices. This
ensures that the mnemonic form of addressing is used.
●
Operation of the software ROBAR-SV V3.0D in conjunction with ETERNUS CS HE has
only been released for RISC systems. Operation of the software ROBAR-SV V4.0A has
been released without restriction for RISC and Primepower systems.
●
After every restart of a VLS component the associated ROBAR-SV must also be
restarted.
35
Miscellaneous
ROBAR must be installed with the corresponding storage location name (here CEST1).
ETERNUS CS HE is set as the AMU version at installation.
1. Make the following entries in the ROBAR configuration file:
a) Storage location name:
Location=CEST1
b) Number of robots:
robots_count=1
i
The virtual archive system is only supported as a single robot system.
c) VLP address and VAMU port:
robot_address1=TCP/IP(<VLP-adr>,<VAMU-port>)
i
The virtual archive system is accessed exclusively via a TCP/IP connection
(to the VAMU).
d) Virtual devices (are defined as TAPE-C4 devices):
gen_devices
mn1 robot=1 type=TAPE-C4
:
mnx robot=1 type=TAPE-C4
end_devices
The input and output areas of the robot system are irrelevant as far as ETERNUS CS
HE is concerned.
2. The following parameters must be set so that the device mnemonic of the ROBAR-SV
configuration is used:
robot_devid=EXPLICIT
i
For further information on the configuration of ETERNUS CS HE in BS2000 and in
ROBAR, see the manuals MAREN [4] Chapter 8.3 and ROBAR [6].
If a real archive system and a virtual archive system are to be operated together, a
separate ROBAR installation will be required for each of the two robot systems. The
storage location name for virtual volumes must be different from that used for real
volumes.
If several virtual archive systems are to be operated together, a separate ROBAR
installation will be required for each robot system. The volumes of each robot
system must be assigned their own separate storage location.
36
Miscellaneous
3.1.8 Activities in BS2000-CSC
These are necessary if a StorageTek library is connected.
3.1.8.1
General information
CSC Version 6.2 or higher must be used.
If an earlier version is used, the connect to ETERNUS CS HE cannot be set up.
Message CSCX050 is then issued.
!
The virtual connection to ETERNUS CS HE is implemented by emulating a StorageTek
library (VACS). The following preparations are therefore required in order to implement the
host connection to VACS via the StorageTek library interface:
●
After the CSC-Software has been installed (see CSC manual [10]) you will need to
define a virtual server with the following attributes in the CSC Gentab:
SERVER NAME=CEST1,PRONAM1=<vlp>,PRONAM2=,
VIRTUAL=Y,MOUNT=P,AUTOROUT=N,CAPSIZE=0, ,MGMTCLASS=BS2000
The server name (CEST1 in the example) can be freely selected, but may only be a
maximum of 5 Bytes in size and must be identical to the device depot name for the
virtual drives in BS2000 and to the storage location name for the virtual volumes in
MAREN.
Enter the VLP of the ETERNUS CS HE configuration as the PRONAM.
The Parameter MOUNT=P[ROPOSE] must be set. CSC will then mount the virtual
volumes on the devices suggested by BS2000.
This means that dummy devices cannot be used as a virtual server because these are
not known to ETERNUS CS HE and it is not possible to mount volumes on devices of
this type. This also means that CSC does not switch virtual drives back and forth
between the individual computers.
●
The virtual drives must be assigned to this server in the CSC Gentab.
Example:
DE HOSTNAME=HOST1,BS2DEV=B0,UNIXDEV=090,SERVER=CEST1,... DE
HOSTNAME=HOST1,BS2DEV=B1,UNIXDEV=091,SERVER=CEST1,...
etc.
Virtual drives are not switched by CSC and an entry in the PRIO parameter does not
therefore have any meaning.
The value to be specified for BS2DEV is the device mnemonic in BS2000.
The BS2000 devices are numbered sequentially in decimal notation in UNIXDEV, where
the last (lowest) position can take the values 0...9,A...J.
37
Miscellaneous
Archive addresses, which cannot occur in physical archives are also accepted (and
correctly operated by ETERNUS CS HE):
LSM-ID:
Panel:
Slot:
0-F
0-F
0-9,A,B,C,D,E,F,G,H,I,J
The UNIXDEV names in the CSC Gentab must match the VACS libdev name specified
in the GXCC configuration in the Virtual Drives menu.
Example:
A UNIXDEV = 010 in the CSC-GENTAB must be entered in GXCC with the VACS
LibDevName = 0-0-1-0, a UNIXDEV = 122 must be entered in GXCC with the VACS
LibDevName = 0-1-2-2. You must only use decimal numbers (009 is followed by 010
and not by 00A).
For a virtual drive, you can use the same co-ordinates as for a real robot drive. This type
of overlap does not cause problems because the server name (e.g. CEST1) is also
flagged in the drive definition in the CSC Gentab, next to the UNIXDEV, which in this
case is the same.
If you have 2 ICPs with 32 drives each, we recommend that you assign the UNIXDEVs
from 000 to 031 to the ICP0 devices (in the GXCC configuration menu for Virtual Drives;
this corresponds to the VACS LibDevNames from 0-0-0-0 to 0-0-3-1). The devices on
ICP1 can then be assigned the UNIXDEVs 032 through 063. Alternatively, you could
assign the devices on ICP1 the UNIXDEVs 100 through 131.
As a general rule, you can number the devices under UNIXDEV as you wish. There will
be no problems as long as the VACS LibDevName in GXCC is selected appropriately.
But this does, in some cases, make debugging harder and can lead to oversights when
modifying the configuration (e.g. when installing a new ICP).
●
For the real Volumes (used outside ETERNUS CS HE as native), you must also define
a server (if the STK robot system was already being used as native before the introduction of CenricStor, then this entry is contained in the CSC Gentab):
SERVER NAME=SILO1,PRONAM1=<stksun>,PRONAM2=,VIRTUAL=N,MOUNT=A,DEFAULT=Y
The server name can be freely selected, but may only be a maximum of 5 Bytes, and
must be identical to the Device Depot Name for the real drives in BS2000 and the
storage location name for the real volumes in MAREN.
The name of the ACSLS computer must be entered as the PRONAM.
38
Miscellaneous
The attributes VIRTUAL=N and MOUNT=A must be set. MOUNT=A[NY] means that CSC
can also mount drives other than those specified by BS2000 in the mount message. The
DEFAULT=Y parameter means that tape requests occurring as a result of MAREN
messages which do not specify a tape device (e.g. MARM1I2, MARUP45 etc.), are also
directed to this server.
i
3.1.8.2
The Gentab parameter SILONAME is only relevant if in the MARENUCP start
procedure, the parameter PROPOSE has not been set. If this MARENUCP
parameter is missing, then in the event of a free tape request, CSC will locate
and mount a real volume, using the MARENADM statement
//SECURE-FREE-VOLUMES.
●
Alongside the definitions of the individual servers, their respective drives and the
connected BS2000 host, the MAREN parameter is also to be set to Y in the CSC Gentab.
●
The created Gentab is implemented using the CSC Procedure PRC.CSCUTGEN. The
created output file must be specified in the CSC enter file ENT.CSCMAIN.
Activities in ETERNUS CS HE: EMTAPE, VAMU/VACS
The logical devices are installed in the initial or update configuration using the GXCC
interface in the service mode.
ETERNUS CS HE names of the LDs
The internal Centric Stor names of LDs are preassigned and are as follows for emulation
type OS-390:
L<Nnn>
where N = 0 .. 7 (as a rule) is the number of the ICP, on which the emulation is running, and
nn = 00 .. 1F (3F) is the number of the emulation with 32 or 64 LDs per ICP.
Device name and library device name
In the case of VLS-Type VAMU, the device name and library device name are always the
same, and must match the mnemonic of the LDs generated in UGEN.
Similarly with VLS-Type VACS, the device name must the mnemonic of the LDs generated
in UGEN.
The library device name must, however, match the virtual co-ordinates (e.g. 0-1-2-5) of the
StorageTek library, as they were generated in the GENTAB of BS2000-CSC (see section
“Activities in BS2000-CSC” on page 37).
39
Miscellaneous
3.1.9 Multiple ETERNUS CS HE systems
●
When multiple ETERNUS CS HE systems are used it must be ensured that the
computer names are unique in the LAN.
●
In order to avoid LAN performance/LAN load problems in the event of a kernel update
by means of "prepupdate" (cpio: broke pipe) when ETERNUS CS HE is spread over
several locations, the service staff should perform the upgrade separately at each
location.
●
After configuration changes in dynamic ESCON Director operation, e.g. port changes
because of modified cabling, the ICPs must be restarted.
3.1.10 DAS
The settings for the real drives’ cleaning mechanism, for robot sharing mode, and the
entries for the real drives’ configuration which are required to operate ETERNUS CS HE
are made by the service provider.

SX servers
3.2 SX servers
As of K818 EKS 9, CS V2.1supports connection via fibre channel to the business servers
of the SX series SX100-A, SX100-B, SX100-C, SX130, SX140 and SX150 with OSD/XC
Version 1.1 or newer (software package on the basis of BS2000/OSD-BC V5.0C). SX100D and SX160 with X2000 V4.0A or higher and OSD/XC Version 3.0 or higher (software
package based on BS2000/OSD-BC V7.0A) are supported by CS V3.0 and higher.
3.2.1 Connection via FC switch
ETERNUS CS HE on SX servers can be connected to the Emulex FC controller on an SX
server (LP9002 as of FW Rev. 3.90A7 or LP9802 as of FW Rev. 1.01A2 ) via an FC switch
(Brocade; Connectrix McData).
The following FC switches were used in the ETERNUS CS HE test with SX servers:
–
–
–
Brocade Silkworm 3800 Version V3.0.2c
Brocade Silkworm 12000 FW V4.0.0b
Connectrix McData FW 05.02.0013; EC 1030218
3.2.2 Connection without an FC switch
An FC connection of the SX server is also possible directly (meaning without an FC switch)
to ETERNUS CS HE. Loop mode must be set permanently as the FC topology at the HBA
of the SX server and Eternus CS HE.
The direct connection has been tested with CS V3.0 on an Intelligent Tape Controller (ITC).
X2000 V3 and OSD/XC 2.0 (software package based on OSD-BC V6.0) ran on the SX
server - SX140 in the test. A further test with CS V4.0A on the VTA 1500 model in which
the FC controller LP9402DC was used on ICP1, and on SX160, where Solaris 10, the
Leadville driver and X2000 V4.0A were used, plus FC controller LP11002, was also
successful. Loop mode was set permanently as the FC topology in accordance with the
SX160 Service Manual (4 = attempt loop mode only).
3.2.3 Configuring the tape units in ETERNUS CS HE
The virtual tape devices for the SX servers must be configured in ETERNUS CS HE with
connection type FC-SCSI and IBM 3590E emulation.
In contrast to the original IBM drive which is operated as TAPE-C6 under BS2000, the
TAPE-C4 interface is used for the virtual 3590-E1A.
41
SX servers
Example of ETERNUS CS HE connected to SX140:

3.2.4 Configuring the tape devices on the SX server
3.2.4.1
Introductory note on X2000
The BS2000/OSD operating system with the X2000 carrier system is installed on the
BS2000 partition. X2000 is based on Solaris and principally provides the runtime
environment for BS2000/OSD.
The available CPUs of a BS2000 partition are logically divided into CPUs for BS2000/OSD
and into I/O processors which X2000 makes available for BS2000/OSD. The available main
memory is also divided between BS2000/OSD and X2000.
The functions offered by X2000 include:
●
HAL (Hardware Abstraction Layer)
HAL maps the hardware-software interfaces of /390 mode onto equivalent interfaces of
SPARC64 mode.
●
/390 firmware
The /390 firmware component supplements SPARC64 mode and enables existing /390
code to run object-compatibly (im /390 mode; synonym: compatibility mode) on
SPARC64 hardware.
●
Implementation of I/Os and data communication
The fibre channel peripherals are operated under BS2000/OSD by emulating the devices
in X2000 as so-called bus peripherals.
In the event of connection via FC, the BS2000 host behaves, from the ETERNUS CS HE
viewpoint, like an Open System installation. For BS2000/OSD and the emulation layers
below it, the drives generated in ETERNUS CS HE appear to be native SCSI tape devices.
3.2.4.2
Configuration steps
The ETERNUS CS HE devices are made known to the BS2000 operating system through
configuration in X2000 as of Version 2.5A (based on Solaris 8). Generation using IOGEN
in BS2000/OSD is not required.
The following files must be adjusted on the SX server for device configuration:
●
/kernel/drv/lpfc.conf (WWPN binding)
●
/usr/kernel/drv/SMAWLsti.conf (extension Targets/LUNS)
A reconfiguration boot of Solaris must then be performed.
The ETERNUS CS HE devices (BS2 tapes) can subsequently be set up via WSA
(WebSysAdmin).

Setting up BS2 tapes in the WSA
●
Select host connector in BS2000
The host connector (HC) for setting up the BS2 tapes must be specified in the WSA (see
the next section). The HC is defined in BS2000/OSD as a channel from the range 00
through 0F. The channel type IE1(XS) is definitive in BS2000/OSD for the emulated
devices.
Example: BS2000/OSD of SX130 Perseus

Notes:
–
–
Channels not equal to 0* are not virtual channels. These are assigned by the
hardware. They are thus not available for selection for ETERNUS CS HE.
It makes sense (for example because of selective SM2) to select a free channel
from 00 through 0F for ETERNUS CS HE.
In the example, 0B can be selected as HC for WSA.
By configuring the HC with WSA, the HC is automatically added as a channel in
BS2000/OSD by the system (see next section).
●
Entries in WSA
1. Call WSA:
# DISPLAY=nnn.nn.nn.nnn:0.0;export DISPLAY
# WSA
2. Click on the X2000 Bs2Devices icon
3. Click on the BS2 Tapes button
4. BS2 tape menu: Select Create (wait for output)
5. Enter HC, for example B (selected as channel in BS2000; see above)
6. Select /dev/rmt/?cn device node
7. MN is the device mn in BS2000/OSD associated with the device node or LUN (see
vtls.conf above)
8. Unit is automatically updated with the HC setting
9. Click on Ok and wait until channel and device are assigned on VM2000
49
SX servers
For each device mn, 2 EMKTAPE_mn processes run in X2000, provided active=yes is
set for the device in WSA/BS2 Devices.
Example: SX130 Perseus
●
Timeout
In the case of large configurations or if there is a high system load on the SX server,
you are recommended to extend timeout monitoring when configuring ETERNUS CS
HE devices (setting up BS2 tapes with WSA).
The timeout value can be increased in the file /etc/opt/SMAWwsaS/WSA:
# Default timeout for wdmexec commands (in seconds) ...
WSA_TIMEOUT : 255
The WSA_TIMEOUT variable defines the timeout in seconds. The value of WSA_TIMEOUT
can be changed from 45 to a maximum of 255.

3.2.5 Notes
●
Number of devices
An SX server recognizes all 64 devices in an ETERNUS CS HE ICP. To save on Solaris
resources, it is however recommendable only to activate the ETERNUS CS HE devices
which are actually needed in X2000 (WSA).
●
Dynamic addition of devices
The I/O handler permits a maximum of 4096 bus devices. ETERNUS CS HE devices
on the FC also belong to the bus devices. The IOH enables dynamic addition of bus
devices (for example WSA ➟ BS2 Tapes ➟ Create), covering at least 64 devices and up
to 10% of the bus devices already defined. Sufficient memory for dynamic addition of
devices is kept free internally by the system. For further devices, an IPL may be required
for BS2000/OSD after the devices have been entered in
/etc/opt/SMAW/X2000/bs2tab with WSA.
Thus the earlier limit of 32 tape devices in BS2000/OSD 5.0C no longer applies.
●
HSI in BS2000
The virtual 3590-E1A devices are operated by BS2000 via the MBK6-HSI.

BC
Block size
In contrast to Open Systems Solaris … BS2000/OSD 5.0C currently supports a
maximum I/O block size of 32 Kbyte.
54
●
SX servers
Compression
OSD/XC does not support the compression selection HOST.
The BS2000 devices (mn) are permanently linked to the Solaris device nodes via
X2000 with descriptor c (/dev/rmt/*cn) and cannot control compression by means
of volume type TAPE-C3 or TAPE-C4.
Control can only be implemented for a device via ETERNUS CS HE with the configuration setting Compression ON or OFF.
Thus X2000 ensures that data compression is always active in ETERNUS CS HE for a
tape device on the SX server unless configuration is configured with OFF in ETERNUS
CS HE for this tape device.
●
Device sharing, switch, path
SX servers do not support SCSI Reserve/Release.
Using the ETERNUS CS HE devices via a joint WSA Management Server as shared
devices, i.e. exclusively on several SX servers alternately, has not been tested with
ETERNUS CS HE.
The so-called 1:1 configuration has been quality-assured and generally released:
The FC port of an ETERNUS CS HE ICP must be assigned to precisely one FC port
of an SX server and the FC port of an SX server to precisely one FC port of an
ETERNUS CS HE ICP.
This excludes joint use of an ICP port and logical devices in ETERNUS CS HE by
multiple SX servers, by SX and S servers (business servers of the S series, see section
“ETERNUS CS HE on S servers” on page 57) or with Open Systems.
The devices are connected by a single path.
55
SX servers
3.2.6 Restrictions
●
Use of ETERNUS CS HE by the X2000 tool PSR (physical saving and restoring of disks
or individual slices) is not provided for.
●
Before maintenance work that results in the emulations (vtd) in ETERNUS CS HE being
terminated takes place, the tape emulations in X2000 should be disabled. If this is not
done, experience shows that with X2000 V4.0A on Solaris 10 a Solaris reboot will
generally be required to permit the ETERNUS CS HE tape devices to be assigned to
BS2000 again (A0562700 emu.core in X2000 V4.0A).
The tape emulations in X2000 are generally disabled/enabled via WSA. The process of
disabling/enabling a large number of tape emulations on the SX server can be
expedited under X2000 V2.5 using the following commands in Solaris:
/opt/SMAW/X2000/bin/acfconf stop -i MKTAPE
/opt/SMAW/X2000/bin/acfconf load -i MKTAPE
3.2.7 Diagnostic documentation for the tape emulation in X2000
The diagnostic documentation for the tape emulation in X2000 can be found on the
SX server in directory /var/opt/SMAW/X2000/diag/emtape
56
3.3 ETERNUS CS HE on S servers
As of CS V2.1 and BS2000/OSD-BC Version 5.0C support not only the connection of
ETERNUS CS HE via ESCON, but also connection via Fibre Channel - always with FC
switch - on the Business Servers of the S series (S120, S140, S145, S155, S165, S170,
S180, S190, S200).
3.3.1 Firmware/software statuses
At least the following firmware/software statuses are required to operate S servers with
ETERNUS CS HE:
●

10.0A.
●
ROBAR-SV 5.0A00 (this enables ROBAR-CL 4.0A00 still to be used in BS2000/OSD
5.0C). Migration from ROBAR SV 4.0A00 to ROBAR SV 5.0A00 with the rule file EKS
"RO150A002" for Reliant UNIX (Mips) or "RO550A002" for Solaris is urgently recommended.

3.3.2 Connection and configuration
The virtual devices for S servers must be configured as follows in ETERNUS CS HE:
Connection type: FC-SCSI
Emulation:
IBM 3590E
For S servers, a maximum of 64 devices per ICP can be configured in ETERNUS CS HE.
Virtual robot control of ETERNUS CS HE can be implemented both via the VAMU interface
(with ROBAR-CL/ROBAR-SV on the host side) and via the VACS interface (with CSC on
the host side).
Connection of ETERNUS CS HE to S servers is always implemented via an FC switch
(Brocade or Connectrix McData) to Fujitsu’s proprietary channel module FC-SCSI on the S
server.
The so-called inverted Y configuration and the Y configuration have been released, and
also their combination as a so-called X configuration: Multiple ICP ports can be assigned
jointly to a port (FC channel) of an S server, and multiple S servers may make joint use of
the same ICP port. The individual LUNs/tape devices are assigned exclusively to 1 S server
with /attach-device mn in BS2000.

3.3.3 Restrictions
The so-called "1:1" configuration has been released:
It is inadmissible for S servers and SX servers (business servers of the SX series SX100,
SX130, SX140, SX150) or S servers and Open System servers to make joint use of an ICP
port and thus of all logical devices in ETERNUS CS HE on this ICP port. A risk is to be
expected because, for example, SX servers do not support the device reservation
(reserve/release). On the FC switch, no other zone with the ICP port - even if it is not used
- may be entered by another host which does not belong to the S series.
ETERNUS CS HE tape devices and FC disks may not be configured in the same zone on
the FC switch and not on the same channel of the S server.

3.4.1 Configuration in ETERNUS CS HE
CS V3.1D SP04 and higher and ETERNUS CS HE 4.1A-SP00 and higher supported the
connection of SQ servers (SQ100).
The connection to SQ servers is not released for CS 4.0A owing to an lpfc problem.
In ETERNUS CS HE the virtual tape devices for SQ servers must be configured with connection type FC-SCSI and emulation 3590E.

3.4.2 Connection between ETERNUS CS HE and SQ servers
The SQ servers are connected to ETERNUS CS HE via Fibre Channel with an external FC
switch (target mode AUTO in ETERNUS CS HE, see vtls.conf above) or directly - in the sense of without an external FC switch (target mode LOOP in ETERNUS CS HE, see vtls.conf
above). An FC switch enables multiple HBA ports or targets of ETERNUS CS HE to be assigned to the same HBA port in the SQ server. However, alternating use of the same virtual
ETERNUS CS HE tape devices in the SAN by multiple SQ servers or other server types
(SX or S servers or OpenSystems) is not released owing to the missing reserve/release on
60
the SQ server side. In other words an HBA port in ETERNUS CS HE should only be assigned to one HBA port of an SQ server, or it must be configured in the ETERNUS CS HE
LUN Mapping (note: LUN mapping is supported in ETERNUS CS HE V4 and higher).
The devices are connected via 1 path.
3.4.3 About the software configuration on the SQ server
The SQ100 is released with at least the following software statuses:
X2000 V5.1A (basic LINUX SLES 10 SP2)
Operating system package OSD/XC 4.0A (basic BS2000/OSD-BC V8.0)
For X2000 the tape devices can be configured with the Web GUI of the server unit’s SQ
Manager. The BS2000 mn of the virtual tape device is defined here.

If compression with HOST (see vtls.conf above) is set in ETERNUS CS HE for the virtual
tape device, ETERNUS CS HE performs compression when the volume type in BS2000
is Tape-C4 and does not perform compression when the volume type in BS2000 is TapeC3.

4 ETERNUS CS HE on z/OS
4.1 Introduction
An ETERNUS CS HE virtual tape server behaves towards z/OS or OS/390 systems like a
physical IBM 3490E 36-track tape system and is able to communicate with more than one
LPAR in parallel.
The virtual tape drives (devices) offered by ETERNUS CS HE are configured in the HCD
(Harware Configuration Definition) like real connected devices. Dependencies of the
operating system which is in use (SMPE status) are not known.
The physical connection between ETERNUS CS HE and the IBM host is implemented both
via ESCON or ESCON Director channels and via FICON or FICON Director channels. The
technical software connection takes place via a host software for an ATL (Automatic Tape
Library) which runs as a subsystem in z/OS or OS/390. Host software solutions that are
available are: NCS/CSC from SUN/STK, HACC from Fujitsu Technologie Solutions and
CSMVS from Fujitsu Technology Solutions. Dependent on which host software was chosen,
the corresponding Virtual Library Service (library emulation) is set in ETERNUS CS HE.
The type of physical library attached to ETERNUS CS HE (back end) is not visible to the
host.
ETERNUS CS HE can make several different virtual drives available depending on configuration level and ESCON/FICON ports contained. Those with the highest configuration
level can be taken from the relevant ETERNUS CS HE data sheet or the menu of the
ETERNUS CS HE configuration program GXCC.
The information in this manual is expanded on by the installation manual for the host
software solutions NCS/CSC (from SUN/StorageTek), HACC (from Quantum(ADIC)) and
CSMVS (from Fujitsu Technology Solutions); further information is also provided in the
ETERNUS CS HE manuals. For information on tape management systems please refer to
the manuals which the vendors provide.

4.3 Configuration of Logical Drives in z/OS
From the point of view of the host, each virtual tape drive is connected like a physical tape
drive.
With the highest configuration level, ETERNUS CS HE supports 640 3490E tape drives
(devices) simultaneously. The following configuration examples describes a configuration
level for 64 tape drives.
An ICP (Integrated Channel Processor) controls up to 64 virtual tape drives. For z/OS, an
ICP represents up to 4 3490E Control Units (CU). A single 3490E controller supports 16
devices. On ESCON or FICON channels four logical control units (CUs) are defined to
represent all 64 drive addresses. The IOCP subparameter CUADD within the UNITADD
statement is used to define the logical control units (0-3). In a recommended configuration
of 32 logical drives per ICP, only CUADD=0 and CUADD=1 are needed.
Every ICP is equipped with at least two ESCON or FICON ports, which should be used for
redundancy. Both, a direct connection and a switched/cascaded configuration via an
ESCON or FICON director (switch) are possible.

gaps (1E20-1E3F and 1E60-1E7F) can be used to upgrade each of the ISPs later to a configuration with 64 virtual drives. In case of ESCON attachment, TYPE=FC is replaced by
TYPE=CNC.

4.3.2 Virtual Drive Sharing
Sharing of virtual drives can be implemented in SYSPLEX or using tape sharing software
such as CA-MIM. Device sharing between BS2000 and SYSPLEX is not recommended.
ESCON and FICON adapters, CUs and ICPs can be used jointly between z/OS and
BS2000 systems.
i
z/OS uses the missing interupt handler (MIH) to control outstanding channel operations. A timeout value of 10 minutes is recommended for ETERNUS CS HE virtual
drives.
The following MIH entry in SYS1.PARMLIB (IECIOSxx) represents this recommendation:
Example
MIH DEV=(1E00-1E0F), TIME=10:00
/*T3490*/
67
4.3.3 Representation of Virtual Drives in ETERNUS CS HE
The virtual drives of ETERNUS CS HE are defined in accordance with the host software.
NCS/CSC and CSMVS both use the VACS interface, whereas HACC uses the VAMU
interface. Mapping of the virtual drives is done by the LibDevName within the parameter file
of the corresponding software.
The LibDevName for HACC is a two digit decimal or hexadecimal number.
i
If your HACC configuration uses more than 100 virtual drives, make sure, that the
hexadecimal representation is used during the initial setup of the VAMU drives.
The LibDevName consists of the virtual quadruple (ACS, LSM, panel, row). For mount
balancing purposes, special logic is applied to the numbering of the virtual drives. Details
of the schema used for numbering the drives are provided in the section on setting up
NCS/CSC (see section “NCS/CSC” on page 74).
68
4.3.4 Logical Volume Definition
Before logical (virtual) volumes (LV) can be defined using the GUI, the logical volume group
(LVG) has to be defined first. In versions V3.1D SP04 and higher, the LVG supports a new
attribute: Auto Labelling (default disabled!)
Using Auto Labelling makes the process of volume initialisation obsolete. It generates a
VOL1 and HDR1 record for each logical volume. If you do not enable the Auto Labelling
option, you have to initialise each volume. Refer to the corresponding chapter of the tape
management software that is used in conjunction with ETERNUS CS HE.
The following figure shows the Logical Volume Groups window in which the LVG is created:
69
4.3.5 VACS Interface
The Virtual ACSLS interface enables ETERNUS CS HE to look like a SUN/STK ACSLS
server. Scratch subpools must be defined here, to map logical volume groups to a scratch
subpool.
i
Before you use the following procedure, refer to the explainations that correspond
to your tape management software. The sequence is also dependent on the initialisation process of the logical volumes.
1. Log in to ETERNUS CS HE via a TELNET session (CS 3.x) or ssh session (CS 4.0 and
higher) and start the operation with:
cmd_proc
2. First define the pool ID that will be used. The available pool IDs lie between 1 and 254
and are defined using the following syntax (use of the default pool 0 is not recommended):
define pool &low_water_mark &high_water_mark &pool_ID
It may be a good idea, to specify a high_water_mark to a value, that covers one week
of scratch usage. Then you get an information, in case you have defined too many
scratch volumes, which may occupy backend space. For low_water_mark specify a
value that fits your requirements.
Example:
define pool 600 3000 1
Pool-ID 1 is now defined and you can query it or all pools with:
query pool 1 or q pool all
Reply may be as follows:
ACSSA> q pool all

3. Now assign the volumes that belong to LVG01 to the scratch pool:
set scratch &pool_ID &volrange
set scratch 1 A00000-A00999

Note, that the volser is case sensitive. For mainframe volumes use capitals!
After the volumes are assigned to pool ID 01, the output of the query pool 1 looks

After a mount has taken place for a virtual volume, for security reasons the virtual
volume loses its scratch status. Although it is still a scratch volume from the
viewpoint of the tape management, ETERNUS CS HE regards the volume as a data
volume. After the next scratch synchronization, the status of the volume is reset to
scratch in VACS. The query pool and the query scratch commands only show
counts or volumes, that have the scratch status in VACS.

Host Software Functions
4.4 Host Software Functions
The different host software solutions, that are available for an ETERNUS CS HE attachment
to z/OS, optimize the functionality of the system and should be chosen by the installations
needs Three major functions are represented by the host software and will be discussed
here. These functions are:
●
Allocation Influencing
●
Message processing and automation
●
Scratch synchronisation between ETERNUS CS HE and tape management
4.4.1 Allocation Influencing and Scratch Subpooling
In a z/OS environment, tape processing is done by the application in two ways. Tape
volumes are allocated either specific or nonspecific.
A specific tape request is either issued by coding the VOL=SER parameter in JCL, by the
application itself during dynamic allocation (e.g. DFHSM recall) or by requesting an existing
file via the OS catalog. In contrast to the JCL VOL=SER parameter together with the
UNIT=esoteric parameter, the other two allocation requests end up in a generic device
allocation, which in case of ETERNUS CS HE virtual drives is 3490.
In a mixed configuration (i.e. ETERNUS CS HE and other non-ETERNUS CS HE 3490-type
drives), such a request may end up in an allocation, where an ETERNUS CS HE logical
volume should be mounted on a manual drive or a physical volume should be mounted on
an ETERNUS CS HE virtual drive. To avoid this situation, the control program influences
the allocation via the subsystem interface by modifying the eligible device list (EDL).
A nonspecific allocation requests any available tape, that can be used for output. These
volume are referred as scratch volumes. Scratch volume ranges may be grouped by function
or size and are represented by a logical volume group (LVG) within ETERNUS CS HE. This
is also called scratch subpooling.
i
72
The expression scratch subpool is understood differently in many views. Some
functions refer to a scratch subpool as a volume range or even multiple ranges
independently from the status, whereas from an ACSLS/VACS point of view, only
the volumes that have a scratch status belong to the pool.
Host Software Functions
Normally the esoteric name of the tape subsystem is specified for example in the JCL and
in this case no allocation influencing is necessary. For ease of use, installation may want to
specify a higher level of esoteric or a generic name for the allocation request. In this case
the control program can execute allocation to the corresponding esoteric name in accordance
with the file or job name. This kind of function varies with the supported software packages
and will be discussed in the corresponding chapter, that explains the differences between
NCS/CSC, HACC and CSMVS .
4.4.2 Message Processing and Automation
The host software analyzes messages for the tape volumes and communicates with
ETERNUS CS HE in order to control the mounting and dismounting of volumes. Tape
volume related messages may be issued either by the operating system itself or by the tape
management system. The tape management system may also change or suppress OS
messages. Refer to the discussion of supported tape management software for more information.
Messages for mounting/dismounting volumes are always analyzed in order to obtain the
function which is to be performed, the device address and the volume number.
Furthermore, a scratch subpool can be selected on the basis of various criteria (e.g. file
name or job name). Scratch subpooling may also be implemented via the tape
management system. Please refer to the section, which explains the different tape
management software.

4.5.1 NCS/CSC
This chapter gives important information on the installation and customisation of CSC/MVS.
It does not replace the SUN/STK documentation. The information that is given is based on
NCS 6.2.0 and also applies for ELS 7.0. When applicable, any special features of ELS 7.0
are also pointed out.
4.5.1.1
Overview
The Nearline Control System (NCS) is a software package to drive SUN/STK libraries in a
z/OS or OS/390 environment. It provides the basic function SMS and optional subfunctions.
The subfunction Client System Component for MVS (CSC/MVS) is used to attach the
ETERNUS CS HE VACS emulation. The CSC covers the functions Message Processing and
Automation and Scratch Synchronisation. It communicates with VACS via TCP/IP. Allocation
Influencing is covered by the Storage Management Component (SMC), which is the base
function of NCS.

The function SOS6200 for HSC contains load modules for scratch synchronisation,
that are also used by CSC. If you do not install SOS6200, you have to manually
maintain the module that corresponds to your tape management software.
Assemble and linkedit it to the CSC load library. A sample source code for
SLUDRCA1, SLUDRTLM and SLUDRRMM is provided in the software package of
NCS for HSC in library SLSSAMP. If you decide to install SOS6200, the ready to go
load modules are contained in library SLULINK. Please refer also to the CSC
System Programmer's Guide.

The SERVER parameter is set to ACSLS because ETERNUS CS HE emulates this type of
attachment.
Add the IP address of ETERNUS CS HE and the name of your TCP/IP started task to
INTERNET and TCPN.
For LIBDEV specify the esoteric name of your logical ETERNUS CS HE drives. By default
ETERNUS CS HE is represented as ACS1. Therefore you have to specify ,cs_esoteric.
If you need any other numbering of the ACS ID, please check the first digit of the virtual drive
coordinate during the VACS setup and also specify the correct number of commas
preceding the esoteric name. The count of commas represents the ACS number.
In case you also use other tape drives than ETERNUS CS HE, specify the esoteric name
of these non library drives.
The LIBUNIT statement must contain all ETERNUS CS HE logical drives. It must match all
drives, that are contained in the esoteric that is given under LIBDEV.
UNITMAP contains the virtual drives location of ETERNUS CS HE logical drives. Please
make sure, that it matches the definitions of the VACS setup. The example defines 64
logical drives that are represented by two ICPs. The distribution of the logical drives across
LSMs should allow mount balancing across the ICPs. Please refer to the chapter, which
explains virtual drives coordinates (see section “Virtual Drives Coordinates” on page 80).
Make sure that you have a file or member that contains a valid license key for NCS/CSC
under LKEYDEF.
The parameter PORT does not take effect under SERVER(ACSLS). It cannot be used to
restrict communication ports to enable a firewall management.
78
In addition, please observe the following hints during the setup:
●
CSC runs as an OMVS user. When you add a userID for the started task, make sure, that
an OMVS segment is defined for it. Also make sure, that the directory for this OMVS
user is read/write enabled. If both actions are not accomplished, unpredictable results
may occur. CSC only will only give an error message, that it cannot connect to the
library server, in this case VACS. You may check with your security administrator for
assistance.
●
CSC uses TCP/IP services. The function PORTMAP is used. Please check that the
PORTMAP started task is automatically started by TCP/IP and port 111 for TCP and
UDP is activated. For more information, please refer also to the chapter Firewall:
section “ETERNUS CS HE NCS/CSC network attachment via firewall in a z/OS
environment” on page 93.
●
One started task of CSC manages one and only one ETERNUS CS HE. If you are using
multiple ETERNUS CS HE systems or a SUN/STK library via CSC, define the appropriate number of CSC subsystems. Remember to adjust the LIBUNIT statement
accordingly.
●
CSC and HSC both use the functionality of the Storage Management Component
(SMC). There is only one SMC started task per z/OS image, independent from the
number of CSCs.
●
If you are running JES3, please specify ALLOCDEF DEFER(ON)in your SMC startup
commands to enable message processing for scratch subpooling.
●
Whereas the SMC subsystem name and the started task name have no dependency
on each other, please note, that the first four digits of the started task name of the CSC
must match the CSC subsystem name.
●
With NCS 6.1 the processing of TAPEREQ statements was moved from CSC and HSC
to SMC. In a mixed environment the correct tailoring of the TAPEREQ statements is
essential. We recommend, to use
TAPEREQ VOLT(N) ESOT(CS_Esoteric) MED(STD) REC(36TRACK)
as the very last statement.
●
With NCS 6.2 the processing of TAPEREQ statements has been switched to POLICY.
The TAPEREQ statement is still supported for reasons of compatibility. A REXX is available in the SMC.Samplib for migrating from TAPEREQ to POLICY.
●
With CSC and SERVER type ACSLS, which is used for ETERNUS CS HE, also the
parameter SUBPOOL for scratch subpooling is not supported with TAPEREQ. Instead,
the SMC user exit 01 has to be used. Please refer the the chapter “Scratch Subpooling”
on page 85.

4.5.1.3
Virtual Drives Coordinates
Virtual drive coordinates are defined during setup of Virtual Library Services. These coordinates must be mapped in the UNITMAP statement of the CSC parameters. The coordinates
represent a SUN/STK ACS and contain: ACS-ID, LSM-ID, PANEL-ID and DRIVE-SLOT. As
all ETERNUS CS HE virtual volumes own the same virtual slot, which is 01:01:01:01, a
scheme can be set up to avoid virtual pass-thrus and to perform drive allocation across
ICPs.
All virtual drives of a logical control unit are spread across all LSMs, i.e. drive with
subschannel address 00 is mapped to LSM x'01', 01 to LSM x'02' and so on until 0F is
mapped to LSM x'10'.
The PANEL ID begins with '01' and represents the drive wall or panel. A drive wall can
accommodate up to 20 drives. For the sake of clarity, only IDs 01 through 16 should be
used. Consequently, if your configuration contains more than 256 virtual drive addresses,
PANEL ID '02' is available. The drive location within a panel starts with 0.
The diagram shows examples of some allocations to demonstrate the logic. The drive
location within a drive panel is not shown. Drives of ICP0 are are mapped to position 0, ICP1
to position 1, IPC2 to position 2 and ICP3 to position 3.

The following two tables show the sample configuration from above with 4 ICPs and 32 logical drives each. It is assumed that it is a split configuration with ICP0 and ICP2 on one site
and ICP1 and ICP3 on the second site. This config distributes the mounts to both sites. The
tables also show the CUADD value of each address range that is used for the HCD process.
In the example a maximum of 4 drive positions per panel are occupied in order to demonstrate the distribution to another panel:

The next example shows 2 ICPs with 64 logical drives each. In this case the logical drives
of a single ICP are distributed to two virtual drive walls. Within a drive wall the positions of
logical drives of ICP0 and ICP1 are interleaved. Position 0 and 2 are mapped to ICP0 and
position 1 and 3 to ICP1:

Scratch Subpooling
When NCS/CSC is used to control ETERNUS CS HE, the scratch subpooling function of
the tape management software is used. Please refer also to the section that corresponds
to your tape management software.
To process the changed or additional mount messages of the tape management software,
SMC user Exit 01 are provided depending on the software used: RMM, CA-1, TLMS and
Control-T. The exits themselves comprise static source code which is compiled together
with the table configured by the user. This table is common for CA-1, TLMS and Control-T.
A separate version is available for RMM. The reason is the length of the scratch pool name,
85
which is 13 digits for CA-1, TLMS and Control-T. For RMM it is eight digits and the exit also
allows to define a default pool ID. The table itself is automatically included in the source
code by using the assembler copy statement. As SUN/STK has announced that CSC format
exit will not longer be supported in a future version of NCS, all delivered source code is HSC
format.
Example for CA-1, TLMS and Control-T Member SPTABCTS

THIS TABLE IS USED TO MAP TAPE MANAGEMENT SCRATCH SUBPOOL
*
NAMES TO A CSC POOLID. POOLIDS 1-254 ARE AVAILABLE EXCEPT
*
POOLID 238 WHICH IS X'EE'. X'EE' IS USED FOR ERROR INDICATION.
*
IN CASE YOU NEED POOLID 238, CHANGE THE SOURCE CODE OF THE
*
EXIT TO REFLECT YOUR ERROR POOLID.

THIS TABLE IS VALID FOR CA-1, TLMS AND CONTROL-T

Tailor the table SPTABCT or SPTABRMM according to your needs. If you plan to use this
exit, note that scratch subpool 238 (hex 'EE') is used as an error indication in case a subpool
name could not be matched. If you want to use it for other purposes, please change the
source of the exit 01 accordingly.
The pool IDs are coded in decimal. For CSESO specify the esoteric name, that you also
used in the CSCPARMs under the LIBDEV statement. The esoteric name is used by
EDTINFO macro services within the exit to mapped all ETERNUS CS HE devices. This
mecanism secures, that configuration changes concerning the logical drive range are
applied automatically.
i
For CA1 and TLMS please make sure, that the additional mount messages TMSxxx
and CTSxxx are not suppressed by MPF.

The RMM version enables you to define default pool IDs by LPAR name. You may use the
same pool ID for multiple LPARs that share a RMM CDS. Using the default table allows you
to use the same storage group for different sysplexes. However, you cannot mix pool
assignment using SMS pools and non-SMS pools.
Once you have completed the table SPTABCT or SPTABRMM, compile and linkedit the exit
to the NCS/SMC load library (SMCLINK) as follows.

4.5.1.5
Scratch Synchronisation
Scratch mounting in a NCS/CSC environment is performed under the control of the library
server. The library server selects a volume to be mounted on a nonspecific request. The
library server for ETERNUS CS HE is VACS. VACS keeps track of the status of the volumes
and groups these in subpools (see section “Scratch Subpooling” on page 85). The scratch
status of volumes in VACS has to be kept in sync with the tape management system.
The synchronisation normally takes places once a day during the daily maintenance job of
the tape management system. In case of NCS/CSC it is an asysnchronous process. The
CSC utility program SCUCONDB reads the contents of the tape management database
and creates scratch commands that are sent via the network to VACS. You can do an incremental or a full synchronisation. The started task for CSC must be active.
i
SCSCONDB supports RMM, CA-1 and TLMS. To synchronise Control-T with
VACS, a REXX script is offered that creates scratch commands out of a scratch
report. Please refer to the corresponding documentation within this chapter.
As an effect of the asynchronous process, it may happen that a volume is mounted by VACS
that is not scratch in the tape management database. In this case, the tape management
system will reject the usage of the affected volume and request a remount. VACS automatically selects another volume and processing continues.
i
Due to the asynchronous process, ETERNUS CS HE option Erase Scratch Volume in
the LVG options may be an issue. Make sure, that you only run incremental scratch
update or stop tape processing during full synchronisation.
The CSC utility will check the complete tape management database and create scratch
commands for every scratch volume in case of a full synchronisation. When you use the
EXEC parm TODAY, it will perform an incremental synchronisation and create scratch
statement for all volumes that became scratch today. The scratch command file can contain
volumes that are not known by VACS. The resulting warning messages may be ignored.
If your installation uses multiple CSC started tasks, the output of SCSCONDB cannot be
used as it is. The produced scratch commands do not contain the parameter SUBSYS. By
default the commands are then sent to the first CSC subsystem. The subsystem parameter
must be added. For this purpose a REXX procedure is provided that adds the SUBSYS
parameter and also selects only volumes out of a predefined volume range. Using this
procedure also avoids unnecessary network traffic during the synchronisation. The REXX
procedure SCRCSC uses positional parameters from the EXEC-PARM-statement. These
are:
1. Name of the procedure itself
2. Name of the CSC subsystem that should be synchronised
3. Volser range to select valid LVs
For each volser range use a separate step.

Scratch synchronisation with Control-T
The SCUCONDB utility does not support Control-T. Scratch synchronisation is accomplished using a scratch list of Control-T, that can be created using CTTRPT/CTTRFSCR.
The scratch list produced as a result of this procedure will look like this:

The scratch report is input to the REXX procedure SCRCNTLT. Please refer to the section
“User Exits and Scripts” on page 152 for details. The provided REXX script selects all
scratch volumes from the report, which is then a full synchronisation. If you want to run an
incremental synchronisation, restrict the scratch report to volumes that became scratch
today. Please consult the Control-T manuals for more information.
The complete scratch synchronisation process for a Control-T environment is shown below:

4.5.1.6
ETERNUS CS HE NCS/CSC network attachment via firewall in a z/OS environment
In a z/OS system environment, that attaches ETERNUS CS HE via a firewall and CSC, the
following considerations must be taken:
ETERNUS CS HE incoming ports can be fixed, using the VACS configuration. Please refer
to the ETERNUS CS HE documentation Service Manual GUI Module and the StorageTek
ACSLS documentation chapter G.
Mainframe incoming ports cannot be fixed within CSC. Therefore TCP/IP parameters can
be used, in case, no other application uses dynamic UDP high ports. If this is the case,
all UDP high ports should be reserved and the incoming port(s) for CSC should be
assigned. One port is needed for each CSC started task. Assume, that port 50099 and
50199 are used as incoming ports for two CSCs:
93
The TCP/IP parameters should include:
PORT 50099 UDP CSC1
PORT 50199 UDP CSC2
PORTRANGE 1024 49075 UDP RESERVED
i
The syntax is misleading, as PORTRANGE uses a starting port number and a
count of ports. So you have to do some calculations, instead of just specifying
the range.
Example
PORTRANGE 1024 49075 reserves 1024 to 50098. As 49075 is a count, and port 1024
is included, 1 has to be subtracted from the calculation: 1024 + 49095 - 1 = 50098.
Also make sure, that the highest port 65535 is reserved: 50200 + 15336 - 1 = 65535.
The parameters can edited into a member of the TCP/IP parmlib and then be activated
dynamically using the OBEY command:
VARY TCPIP,,O,TCPIP.TCPPARMS(&member)
If using the dynamic activation, make sure, that the original TCP/IP parms are updated and
reflect the change.
The portrange statements result, that only MF incoming ports 50099 and 50199 remain
open. However there is no guarantee, that CSC1 will use 50099 and CSC2 will use 50199.
It may be dependant on the startup sequence. Also after stopping and starting CSC the
usage may be exchanged.
So additional firewall setup is needed for direction ETERNUS CS HE to mainframe:
CS1 and CS2 must be granted to use both ports 50099 and 50199 for entering MF, instead
of assigning one exclusivly each ETERNUS CS HE.
After the change has been activated, a TCP/IP trace should be taken for verification.
94
4.5.1.7
CSC Troubleshooting
This section should give help with common problems that may occurs during setup of the
CSC configuration
CSC does not start
1. When starting the CSC started task, make sure, that the messages
SCS3247I Network interface state active
SCS0880I Recovery request successful; the LCS is reconciled to the
current MVS/CSC state
SCS0517I MVS/CSC subsystem CSC1 initialization complete
show up. Instead you may see:
SCS3246I Network interface failure, attempting recovery
There are several reasons why the network interface does not get active:
●
TCPIP portmap service is needed to run CSC. Is the PORTMAP started task
active?
●
Are there multiple TCPIP started task on the system and does the CSC parameter
set reference the correct STC?
●
Is the correct IP address specified in the CSC parameters?
●
Is an OMVS segment defined for the userID of the CSC task?
●
Is the OMVS user directory of CSC write enabled?
●
Is there a firewall between z/OS and ETERNUS CS HE and are ports blocked?
2. When starting the CSC started task the following the messages appear:
SCS0661E No cartridge-type UCB for specified LIBUNIT 6410
SCS0665I SCSPARM UNITMAP entry for device 6410 ignored
The messages may report multiple virtual drive addresses. Make sure, that the CSC
parameters are coded correctly. Check LIBUNIT and UNITMAP statements. If the
messages appear for drives with subchannel addresses 10-16, make sure, that the
coordinates in UNITMAP are coded in hex notation.
3. When starting the CSC started task the following the messages appear:
SCS0726E ACS esoteric CSTEST supplied on SCSPARM LIBDEV parameter for
ACS 01 contains devices in ACS 09 of UNITMAP mappings
The LIBUNIT parameter is not coded correctly. Check that the comma count is correct
and the esoteric name for ETERNUS CS HE logical drives matches the configuration.
95
Scratch volumes are not mounted
CSC shows the following message:
*02 #SCS0918D Mount of SCRTCH on drive 6301 failed, reason code: 0105 NO
SCRATCH TAPES; reply "C"ancel or "R"etry
Reasons:
●
The required user exit 01 is not active.
Check with F SMC,UEXIT LIST command.
●
The requested subpool does not contain any scratch volumes.
Check with VACS command q pool all (refer section “VACS Interface” on page 70)
●
Subpool not assigned by exit.
Enable CSC log and check log messages for the pool ID that was assigned. If subpool
0 was used, check user exit table for errors; else check esoteric name for ETERNUS
CS HE logical drives that is also defined within this table (see section “Scratch
Subpooling” on page 85; label CSESO for CA1 version and CSTORUNT for RMM
version).
4.5.2 CSMVS
The CSMVS software was especially developped fo ETERNUS CS HE and is documented
under: CSMVS Installation & Administrator Guide.
This chapter only gives additional information on the software environment to avoid redundancies to the original document.
CSMVS supports DFSMSrmm, CA1 and TMLS as tape management software. For
integration of scratch subpooling, refer to the corresponding chapter in this document:
–
–
section “DFSMSrmm considerations” on page 127 for RMM and
section “CA1 and TLMS considerations” on page 141 for CA1.
This is the prefered method to implenet scratch subpooling.
In both cases (RMM and CA1), the VPOOLxx statement in CSMVS parmlib member
CSPARMST is used, to map the pool name to the VACS pool ID.
The documentation also mentions differences for installations with unique and not-unique
esoterics with ETERNUS CS HE. Keep in mind, that normally read mounts are allocated
via the OS catalog, which is related to a device generic. In this case the not-unique
esoterics installation procedure applies.
96

LOAD balancing with LMS/CSMVS
To achieve LOAD balancing via the ICPs, the LMS/CSMVS must be notified of which tape
devices (device number) are located on which ICPs.
Example MTCSICP macro in MTCSACT module
MTCSACT
CSECT
MTCSICP ICP=0,LOW=8000,NUM=32,DSN=NO,TYPE=INITIAL
MTCSICP ICP=1,LOW=8020,NUM=32

4.5.2.3
Scratch alignment between RMM/CA-1 and ETERNUS CS HE for LMS/CSMVS
Scratch alignment is implemented for LMS/CSMVS with RMM and CA-1 via an exit. For
each tape which returns to the scratch pool, the pool is modified in such a way that a console message in the following format is generated:
CSC001A <volser>
With this implementation scratch alignment takes place synchronously to RMM/CA-1. If the
implementation via the exit is not wanted, scratch alignment can also take place using the
batch program described in section “Setting manual scratch for ETERNUS CS HE from the
host”. The list of tapes from the tape management housekeeping job is used as the input
here.
4.5.2.4
Setting manual scratch for ETERNUS CS HE from the host
It is recommended that the tapes should be set to scratch for ETERNUS CS HE from the
host instead of doing this in ETERNUS CS HE using the cmd_proc program. For this purpose, the first time scratch tapes are labeled with the tape label program of TMS (RMM or
CA-1), the CSMSCRT program is used in a second step.

4.5.3 HACC
4.5.3.1
Overview
The HACC is a software package which was originally created to drive Quantum/ADIC
libraries in a z/OS or OS/390 environment. It also can be used to control an ETERNUS CS
HE. If multiple ETERNUS CS HE systems are used, a separate instance of the HACC must
be started. The HACC communicates with ETERNUS CS HE via the VAMU feature, which
emulates the Grau AMU of a physical library. ETERNUS CS HE can run multiple VAMU
instances which use a dedicated pair of TCP/IP ports. Each LPAR running a primary HACC
must use a separate VAMU to ensure propper functioning. Special attention must be made,
if multiple LPARs share a tape management database. In this case, one LPAR will be used
to run a primary HACC, whereas the other LPARs run secondary HACCs. Up to 7
secondary HACCs can be set up. Please refer to the configuration section for more details.

The primary HACC performs mount automation by analysing mount related messages and
sends commands via the VAMU interface.
Allocation influencing is not performed by the HACC directly. For scratch mounts and
specific mounts, that are not result of a catalog search (e.g. VOL=SER=anyvol in JCL), the
correct esoteric name for the ETERNUS CS HE drives must be coded. For volumes that are
103
mounted based on a catalog search, a catalog user exit is used to modify the allocation of
the drive. Please refer to the corresponding section in the HACC documentation that
explains the installation of LKSVC26.
Scratch mounting is controlled by the HACC itself. The HACC uses a file called HACC
ARCHIVE. In case of ETERNUS CS HE, the only purpose of the ARCHIVE is, to register
to scratch or private status of a virtual volume. The HACC selects a scratch volume from
the ARCHIVE and issues then a specific mount via VAMU. The size of the ARCHIVE is
dependend on the number of virtual volumes that are defined.
Note, that in contrast CSC and CSMVS direct VACS to mount any scratch volume out of a
scratch pool. This is one of the main differences between CSC/CSMVS and HACC
functionality.
4.5.3.2
Installation and Customisation
HACC is installed via the SMP/E program. The installation procedure is explained in the
HACC Installation and Customization Guide.
The following table is an extract of the HACC Installation and Customization Guide. Additional
information is provided if necessary.
1. Satisfy installation preconditions
2. Define ALIASes
3. PARMLIB definitions
4. Install MVS allocation influencing (when necessary)
This step is important to enable allocation influencing for cataloged datasets.
5. Load the installation tape (SMP/E, NON-SMP/E)
6. Create HCC work files
If you share a tape management database among multiple LPARs, you must define an
exchange log file for every secondary HACC (client). The primary HACC checks this file
for outstanding mounts. Additionally the exchange log is used to trap the status of the
virtual drives.
7. Modify the search algorithm for HACPARM (optional)
8. Create a user interface under ISPF
The user interface under ISPF is important, because it is used to initialise the HACC
ARCHIVE. Please refer to the HACC ISPF User Guide.
9. Definitions in HACPARM1 member
See the parameter example in section “HACPARM1 example” on page 106. Short
explainations of ETERNUS CS HE most important parameters are given also.
104
10. Generate the HCC archive (HAA)
The ARCHIVE is a VSAM cluster to track the scratch status of the virtual volumes.
Please refer also to the definitions of the virtual robot (racks) that must match the count
of the virtual volume. For every virtual volume you need a virtual slot. The creation of
the ARCHIVE initialisation is shown in section “HACC ARCHIVE initialisation” on
page 117.
11. Create the HCC start procedure
The start procedure of a primary HACC looks like this:
//HACC
//
//
//
//
//
//
//
//
//
//HACCPROC
//
//
//
//
//
//
//
//
//
//
//
//
//
//STEPLIB
//HACCPARM

DD DSN=HACC.ZHC300.LOAD,DISP=SHR
DD DSN=SYS1.PARMLIB(HACPARM1),DISP=SHR
For the first start after an IPL of the system that hosts the primary HACC, you should
specify FMTU=Y and FEX=Y during startup of the HACC. Unit log file and Exchange
log files are formatted. For a secondary HACC specify SYS=SECx. The x represents
the suffix of the exchange log that this system should use.
For more information, refer to the HACC documentation.
12. Adapt scratch tape processing
See section “HACC Scratch Synchronisation Process” on page 126
105
13. Check / adapt the communication interface
14. Enable the RACF authorization call (optional)
15. Adapt user exits (optional)
16. Function tests (recommended)

SYSDEF1: specify VTLS for ETERNUS CS HE
2
Use STIMER=01 so that the exchange log dataset is checked every second for
outstanding mounts. As ETERNUS CS HE is a virtual tape system this makes sure, that
mount times a minimised.
3
Under HACNET specifiy the VAMU network environment. The subparameter type is
used for the AMU and not for the type of the HACC (primary or secondary). The ports
are defined during VAMU setup.
4
TMS=SEQF in the example is used for a flat file, that contains the scratch volume list.
It can be used also for any tape management system. You may need a script to format
your scratch list to match the SEQF file (volume serial on position 1). For CA1, TLMS
you may also use the appropriate keyword for TMS. For RMM use the DFSMSRMM
sample job of the HACC.SAMP file to create the sequential file during RMM housekeeping.
5
The VOLGR statement defines scratch volume pools. Make sure, that the definitions
map the LVGs defined in ETERNUS CS HE. Volume subpooling features of the tape
management system may be used. Please refer to the corresponding chapter of the
tape management system, that you have installed. In this case, the 5th subparameter
refers to the poolname, that is shown in the modified mount message. If you prefer not
to use the subpooling feature of the tape management system, you may direct
subpooling based on JOB or DSN. In this case you have to add the subparameter
PREFER=DSN|JOB to the VOLGR statement. You also have to add DSNGR and/or
JOBGR statements to your HACC parms. For additional information, look up the HACC
documentation.
6
For UNITNUM specify HEX so that you can use up to 256 virtual drives. Te default is
decimal and in this case only 99 drives are available. This parameter must match the
VAMU settings.
7
Every virtual drive is defined by a UNIT statement. The first subparameter specifies the
MVS address. The second parameter is the virtual drive position defined by the
VAMU and must start with 01. If you plan for upgrades of the number of virtual drives,
make sure that you keep the gap large enough. In the example the second list of
devices starts at 41, so that 21-40 leaves a 32 virtual drive range for enhancements.
For ETERNUS CS HE, the third and forth subparameter of the UNIT statement is
always 1.
8
The statement: LDEV=R01,01,01,20,01,50,01,50,50,S=1,R=1 defines the virtual
robot rack. In this case it defines 20 segment with 50 rows and 50 columns. This makes
up to a total of 50,000 virtual volumes. If you need a larger number of virtual volumes
you may add additional rack statements:
LDEV=Rnn,nn,01,20,01,50,01,50,50,S=1,R=1 this adds 50,000 volumes. Please
115
copy the other LDEV statements from the example to your production parm set. Instead
you may use: LDEV=R01,01,01,40,01,50,01,50,50,S=1,R=1 to specify 100,000
virtual slots.
9
The MAXCOOR and MAXVOL statement should exceed the number of slots defined in
the LDEV=Rxx statement, as for the management of the virtual robot additional coordinates are created. The count you specify is used when you define the ARCHIVE control
file.
10 HACC system control files (refer job ASPALLOC out of HACC.SAMP file):
10.1
As explained earlier, the UNITLOG is used to track the status of the drives in
case of a restart of the HACC. Under PDSNULOG you specify its name.
10.2
The Name of the ARCHIVE file is registered under PDSNARCH. The creation
of the ARCHIVE is documented in the HACC documentation. Please refer also
to the next paragraph.
10.3
Message logs are used to document, which messages were analysed. A set of
logs are defined under PDSNMLGx, where x represent a number from 1 to 4.
You may want to archive the message log when a switch to the next available
log occurs.
10.4
The EXCHANGE logs, that are used for every secondary HACC are defined via
PDSNMLGx, where x represents a number from 1-7.
11 SECURITY: Defines user security for different HACC functions. For detailed information, refer the HACC manuals. Please note, that for TYPE=HAA, ACCESS=ALL is
not valid.
116
4.5.3.4
HACC ARCHIVE initialisation
Once the ARCHIVE file is allocated, you run the initialisation process via the ISPF interface.
In case you have not created the HACC parms via an editor, you have to load the ISPF table
for the HACC parms first. Then you run the HACC Archive Administration HAA via option
2. Before you press enter check, that you have specified the correct name of the
HACCPARM.

Leave the dialog pressing PF12.
If you need to define new volser ranges or want to change these, you have to update the
ARCHIVE file. The easiest way is to create a new ARCHIVE with the updated specifications. Before it can be used, resync your tape management database and the ARCHIVE file
to reflect the current scratch status.
125
4.5.3.5
HACC Scratch Synchronisation Process
Scratch mounting is performed under control of HACC. HACC selects a scratch volume
from the ARCHIVE file and directs a mount for this volume to ETERNUS CS HE. So from
the viewpoint of ETERNUS CS HE, each mount in conjuction with HACC is specific. HACC
merely executes a STUB for the virtual scratch volume, which means that it is not reloaded
into the tape volume cache.
The TMS statement of the HACPARMx member informs HACC about the tape
management environment. Please refer to the HACC manuals for further details. In any
case, you can create a sequential file that contains the volsers of the scratch volumes.
TMS=SEQF enables this file to be used during a FREEVOL command. Please note that the
FREEVOL command may use different subparameters. Dependend on the method you
create the scratch file you may have to use another format: If you create an incremental
scratch file (it only contains volsers, that became scratch during the last housekeeping), use
subparameter ADD together with the FREEVOL command. If you create a complete scratch
file, use REP when issuing FREEVOL. In addition, RESET may be used if you prefer to have
the lower number ranges reused. High volsers will then initially remain unused. This way
you can control whether you have defined too many logical volumes (check the count of
unused volumes).
For RMM a sample procedure to create the scratch flat file and to issue the FREEVOL
command is included in HACC.SAMP.
For the very first FREEVOL command use the REP,RESET subparameters.
4.5.3.6
HACC Volume Initialisation
HACC includes a function to initialise volumes automatically. This process is performed
outside the tape management. If you prefer to use this method, please make sure that use
define the volumes into your tape management accordingly (e.g. ADDVOL command with
INIT(N) for RMM). For more information about the automated initialisation process refer to
the description of the TLI command of HACC.
126
Tape Management Software
4.6 Tape Management Software
This chapter explains the setup for different tape management systems.
In case, your ETERNUS CS HE is attached via the VACS emulation, the LVGs of ETERNUS
CS HE have to be mapped to a pool-ID in VACS. This is done, using the cmd_proc application in a command box of the ETERNUS CS HE VLP. The procedure was explained
earlier in this document (see section “Logical Volume Definition” on page 69).
4.6.1 DFSMSrmm considerations
Functions of DFSMSrmm, that interface with ETERNUS CS HE are scratch processing and
scratch volume subpooling. As ETERNUS CS HE also maintains the list of scratch volumes,
a sychronisation process with RMM must be in place.
4.6.1.1
Scratch Synchronisation for RMM
The method, on how scratch volumes are synchronised is dependent on the host software
product, that is used. It is implemented into the RMM housekeeping and may be done
synchronously (CSMVS) using RMM user exit EDGUX200 or asynchronously via an
additional jobstep (NCS/CSC and HACC). Please refer the the corresponding chapter of the
host software.
4.6.1.2
Scratch Subpooling with RMM
Scratch subpooling of DFSMS is implemented either by using DFSMS/ACS routines or by
using user exit EDGUX100. The more flexible way is the use of the DFSMS/ACS routines.
This method is described here to enable users to do it more easily. It applies to all host
software solutions.
i
Before you choose to use this method, please review your current RMM
setup. In case you use a modified exit EDGUX100, check the functions, that are in
use. If this exit already assigns a management criteria, you have to implement this
function into your ACS routines. The default exit checks EXPDT=99000 for catalog
control and assigns a management criteria of D99000, which is mapped to a VRS
with the WHILECATALOG option. The ACS management class routine then should
assign a management class of D99000 when run under the environment of
RMMVRS. This management class of D99000 has to be defined as a dummy class.
The function foreign tape with EXPDT=98000 is not affected using the proposed solution.
The SMS based subpooling relies on a tape library. This can be SMS- or NonSMSmanaged and is configured via the ISMF/ISPF interface. Multiple storage groups can be
defined for a single tape library. These storage groups represent the different scratch
127
subpools. The library type used for ETERNUS CS HE is Non-SMS. It must not be defined
using the HCD/IOCDS process. Before you start the ISMF dialog, make sure that the Tape
Control Database (TCDB) is defined in your system. The TCDB is also called VOLCAT. The
following JCL example can be used to define it. In case you already use an IBM tape library
or IBM virtual tape library, this step is obsolete, because the VOLCAT was already defined
earlier.

DEFINE USERCATALOG (NAME(SYS1.VOLCAT.VGENERAL) VOLCATALOG VOLUME(MYVOL1) CYLINDERS(1 1))
When multiple LPARs access a TCDB, an IDCAMS IMPORT is required for the master catalogs of the additional systems:
IMPORT OBJECTS((SYS1.VOLCAT.VGENERAL) VOLUME(MYVOL1)
DEVICETYPE(3390))) CONNECT VOLCAT
i
-
On no account may you forget the VOLCAT parameter here, otherwise the tape allocation for specific requirements will no longer function.
In case you have no IBM tape library installed, there is no need, to specify more than one
cylinder of disk space, as no volumes are recorded within the TCDB. Only the library entry
is kept. If your system currently does not make use of OAM, you must enable the subsystem
for OAM before you proceed using the Library Management dialog. This can be done using
the MVS system command:
SETSSI ADD,SUBNAME=OAM1,INITRTN=CBRINIT
Or insert the following statement to your system PARMLIB (member IEFSSNxx) before
scheduling an IPL:
SUBSYS SUBNAME(OAM1) INITRTN(CBRINIT)
i
128
There is no need to start the OAM started task, if you are not using an IBM library.
In case of a mixed environment (IBM library and ETERNUS CS HE), please ignore
OAM messages CBR3006I and CBR3002E that occur for the library entry that was
defined for ETERNUS CS HE.
The description below shows a sample procedure for the SMS definitions required. The panel structure can differ according to the z/OS release.

As RMM only run the management class and storage group routines for non-SMS libraries,
the data class and storage class routines need not to be updated. Please note that RMM
will assign the storage class USERMM.
Once you have gone through the process, that was previously discussed, you now can tailor
your ACS routines.
The management class routine is called by RMM under the environment of RMMVRS and
RMMPOOL. Only when run under RMMVRS, the assigned management class is registered
in the RMM dataset record, which then can be used for definition of VRS's. You may use
different logics for the two environments. Please apply the logic that applies to your system
needs. E.g. use filter lists for file names in order to assign different management classes.
137
PROC MGMTCLAS
FILTLIST HSM_ML2
INCLUDE('DFHSM.HMIGTAPE.DATASET')
FILTLIST HSM_BACKUP
INCLUDE('DFHSM.BACKTAPE.DATASET')

SELECT
WHEN (&ACSENVIR = 'RMMPOOL')
SELECT

SET &MGMTCLAS = 'MCLVG01'
WHEN (&DSN = &HSM_BACKUP)
OTHERWISE
END
WHEN (&ACSENVIR = 'RMMVRS')
SELECT

END

DO
SELECT

Now an example for the storage group routine follows:
PROC STORGRP
/***************************************************************/
FILTLIST ............
/***************************************************************/
SELECT
WHEN (&ACSENVIR = 'RMMPOOL')
SELECT
WHEN (&MGMTCLAS = 'MCLVG01')
SET &STORGRP = 'SGLVG01'
END
OTHERWISE
SELECT
WHEN (&STORCLAS = 'LOGGER')
SET &STORGRP = 'LOGGER'
WHEN (&STORCLAS = 'SMSWRK')
.......
The newly defined storage groups have to be mapped to a VLPOOL statement of the RMM
startup parameters. Please stop your tape processing during the activations of the new
parameters and the activation of the changed SMS environment. For the Option statement,
specify SMSACS(YES), to enable RMM to use the ACS routines.
Also add VLPOOL statements; the NAME parameter must match the storage group name:
VLPOOL PREFIX(A*) TYPE(S) DESCRIPTION('LVG01')
NAME(SGLVG01)
EXPDTCHECK(N)
MEDIANAME(3490)
VLPOOL PREFIX(B*) TYPE(S) DESCRIPTION('LVG02')
NAME(SGLVG02)
EXPDTCHECK(N)
MEDIANAME(3490)
VLPOOL PREFIX(C*) TYPE(S) DESCRIPTION('LVG03')
NAME(SGLVG03)
EXPDTCHECK(N)
MEDIANAME(3490)
-
The EXPDTCHECK parameter is necessary to permit volumes to be written to which are
Sratch but have an expiry date in the volume header or for processing with DISP=MOD.
Now convert the changed ACS routines, activate the new configuration and restart RMM.
With the changed configuration, RMM will now change scratch mount messages IEC501A
and IEF233A by adding - POOL=storgrp at the end of the message. This change will be
used by the supported host software solutions of ETERNUS CS HE, to assign a scratch
volume out of the corresponding LVG. Please note, that only the system log shows the
change of the mount message. The change does not appear in the joblog.
139
Checklist to implement RMM scratch subpooling
1. Define the VOLCAT (not nessary if already using SMS tape)
2. Define the OAM subsystem entry (not nessary if already using SMS tape)
3. Define the tape library using ISMF
4. Define one storage group per logical volume group
5. Define one or more management classes for tape
6. Define a management class for catalog control (D99000) and also others if these are
needed for cycle control (for example D99005) (if EDGUX100 function used and VRS
for D99000 previously defined)
7. Tailor your management class routine to query the RMMVRS environment
8. Tailor your storage group routine to query the RMMPOOL environment
9. Translate the changed ACS routines
10. Add SMSACS(YES) to your RMM option statement
11. Update your VLPOOL statements
12. Stop tape processing (RMM)
13. Activate the new SMS environment
14. Restart RMM
4.6.1.3
Volume Definition and Initialisation with RMM
In case you did not you the Auto Labelling option of the LVG, all logical volumes of that LVG
have to be initialised using EDGINERS.
It is very important to use the correct sequence of actions for the process of volume
definition and initialisation. Please refer to the checklist at the end of the chapter for the
recommended sequence.
After the LVs are defined in ETERNUS CS HE, use the TSO ADDVOL command or the
dialog ADDSCRATCH of RMM to register these to the RMM CDS. If you did not enable the
Auto Labelling option, make sure that you set the INIT(Y) parameter of the ADDVOL
command.
140
If Auto Labelling is disabled, start EDGINERS to initialize the volumes now:
//INITCS JOB
//EDGINIT EXEC PGM=EDGINERS,
//
PARM=('INITIALIZE,COUNT(50),NOVERIFY,POOL(A*)',
//
'BATCH(0),STATUS(NOTMASTER)')
//TAPE
DD UNIT=(CSTOR,,DEFER)
//
Use Batch(0), to ensure, that all scratch volumes are initialised. The COUNT value just
groups volumes together for initialisation. The maximum number is 99. For POOL specify
the prefix value of the VLPOOL statement that corresponds to the pool. You cannot use the
NAME contents.
For VACS attachments under NCS/CSC and CSMVS now run the SET SCR command under
cmd_proc of the VACS emulation. The procedure is explained earlier in this section (4.3.5).
i
Please observe the following sequence when defining logical volumes to
ETERNUS CS HE:
1.
2.
3.
4.
5.
6.
7.
Define the logical volume group (Recommendation: Auto Labelling enabled)
Add logical volumes to a group
Add the volumes to RMM
Initialise the LVs with EDGINERS 1
Define the pool-ID in VACS 2
Assign the LVs to the pool-ID using set scratch 2
In case of HACC run the scratch synchronisation process
4.6.2 CA1 and TLMS considerations
Functions of CA1 and TLMS, that interface with ETERNUS CS HE are Scratch processing
and scratch volume subpooling. As ETERNUS CS HE also maintains the list of scratch
volumes, a sychronisation process with CA1 and TLMS must be in place.
4.6.2.1
Scratch Synchronisation for CA1 and TLMS
The method, on how scratch volumes are synchronised is dependent on the host software
product, that is used. It is implemented into the CA1 or TLMS TMSCLEAN/TLMSTRS job
and may be done synchronously (CSMVS) using CA1 user exit TMSXCLN1, asynchronously via an additional jobstep (NCS/CSC) or by the FREEVOL command (HACC).

If Auto Labelling is disabled
2
If NCS/CSC or CSMVS is used
141
4.6.2.2
Scratch Subpooling with CA1 and TLMS
Scratch subpooling of CA1 and TLMS is implemented using SCR and NSM statements in
the PPOPTION parameter file. For CA1, the members are TMOSCRxx and TMONSMxx.
The corresponding members for TLMS are CTOSCRxx and CTONSMxx.
The implementation for subpooling applies to all host software solutions.
The SCR parameters define the scratch subpool, whereas the NSM parameter define
which dataset pattern are assigned to which pool.
********** TMOSCR00 **********
SCRPOOL=SP.LVG01,RANGE=100000-109999,
RANGE=200000-209999
SCRPOOL=SP.LVG02,RANGE=300000-319999
SCRPOOL=SP.LVG03,RANGE=320000-359999
********** TMONSM00 **********
DSN=DFHSM.HMIGTAPE.-,POOL=SP.LVG01
DSN=DFHSM.BACKTAPE.-,POOL=SP.LVG02
DSN=-,POOL=SP.LVG03
After you have defined your pools and pool matching table, activate the new configuration.
The result of this implementation is, that CA1 and TLMS will issue additional mount
messages and keep the original messages IEC501A and IEF233A unchanged. The
additional messages are copies of the originals, where the string PRIVAT or SCRTCH is
replaced by the corresponding poolname. The message is prefixed with a CA1/TLMS
identifier.
Example:
IEC501A M 5540,PRIVAT,SL,COMP,BACKFULL,STEP1,DUMP.BACKUP05.CSL
TMS002 IEC501A M 5540,SP.LVG03,SL,COMP,BACKFULL,STEP1,DUMP.BACKUP05.CSL
4.6.2.3
Volume Definition and Initialisation with CA1 and TLMS
have to be initialised using TMSTPNIT for CA1 or TLMSNITT for TLMS.
After the LVs are defined in ETERNUS CS HE, use the appropriate procedures to expand
the TMC and the VMF, respectively and to add the new volsers to the tape management
system.
142
If Auto Labelling is disabled, start TMSTPNIT or TLMSINTT to initialize the volumes now:
//stepname EXEC PGM=TMSTPNIT or TLMSNITT
// ,PARM='ROBOT'
//STEPLIB DD DSN=your.steplib,DISP=SHR
//TAPEDB DD DSN=your.TMC.or.VMF
//SYSPRINT DD SYSOUT=A
//LABELDD DD UNIT=(tape,,DEFER)
//SYSIN DD *
NEWTAPE NUMBTAPE=count,SER=volser
/*
For automation purposes use the EXEC parm ROBOT. The count for the NUMBTAPE
parameter ranges from 1 to 999 in case of CA1 5.11. For other releases and for TLMS,
please check the manuals. Restrictions may also apply for alphanumeric volser ranges.

4.6.3 Control-T considerations
Functions of Control-T, that interface with ETERNUS CS HE are Scratch processing and
scratch volume subpooling. As ETERNUS CS HE also maintains the list of scratch volumes,
a sychronisation process with Control-T must be in place.
4.6.3.1
Scratch Synchronisation for Control-T
The method used to synchronize scratch volumes is dependent on the host software
product that is used. It is implemented in the Control-T management run which is executed
regularly and is performed asynchronously via an additional jobstep (NCS/CSC and
HACC). Control-T is currently not supported by CSMVS.

parameter statements.
The implementation for subpooling applies to both supported host software solutions
(NCS/CSC and HACC).
The following description gives you an overview of the pool and rules definition facilities of
Control-T. If you need detailed information, please refer to the CONTROL-M/Tape User

This example represents only a simple rule by data set name. If you have more
complex rules or nested rules, please refer to the CONTROL-M/Tape User Guide.
The result of this implementation is, that Control-T will issue its own mount messages and
suppress the original messages IEC501A and IEF233A. The Control-T messages are
copies of the originals, where the string PRIVAT or SCRTCH is replaced by the corresponding poolname and the message prefix is replaced by a Control-T identifier.
Example
IEC501A M 5540,PRIVAT,SL,COMP,DFHSM,STEP1,DFHSM.HMIGTAPE.DATASET
CTT101A M 5540,CSLVG01,SL,COMP,DFHSM,STEP1,DFHSM.HMIGTAPE.DATASET
4.6.3.3
Volume Definition and Initialisation with Control-T
have to be initialised using CTTTPI.
Please refer to the checklist at the end of the chapter for the recommended sequence.
After the LVs are defined in ETERNUS CS HE, you can start the initialisation process (only
if Auto Labelling is disabled).

Host Software Component - HSC
4.7 Host Software Component - HSC
Part of the SUN/STK software suite NCS is the Host Software Component - HSC. The HSC
is used to control a SUN/STK physical library and in addtion with the Virtual Tape Control
System (VTCS) feature used to control a Virtual Storage Manager (VSM). It also is base to
perform an ACSLS type server communication which may be used to control a backend
library of an ETERNUS CS HE configuration. HSC may also be installed, if native tape
drives on a SUN/STK library are used by z/OS. Another option is to use an additional CSC
instance for the native tape drives and to control the library via an ACSLS server. HSC has
only an indirect relationship to ETERNUS CS HE as it may be the vehicle to perform
backend mounts via Library Station. For further details on HSC, please consult the corresponding SUN/STK documentation.
149
Library Station
4.8 Library Station
Another part of the SUN/STK software suite NCS is the feature Library Station. This is the
communication interface for the ACSLS server type setup. Library Station runs within the
address space of the HSC. This chapter assumes that an active HSC environment is
already in place.
The following diagramm shows a z/OS system, that supports an ETERNUS CS HE backend
configuration via LibStation/HSC.

Note that the ETERNUS CS HE frontend and backend connection work totally

There are three typs of communucation:
150
●
CSC talks to VACS to perform ETERNUS CS HE virtual mount.
●
Physical Library Services talks to LibStation to perform physical mounts.
●
Physical mounts, either ETERNUS CS HE backend or z/OS native, are issued by HSC
to Library Control communication.
Library Station
If you want to use the Library Station software to control your ETERNUS CS HE backend
drives, make sure that the required FMIDs are installed. Please refer to section “Installation
and Customisation” on page 75 for more details.
After the software is SMP/E installed, set up the HSC environment to map the new configuration. ETERNUS CS HE drives have to be dedicated. Run the LIBGEN process to include
the new drives and/or library and add a HOSTID for drives, that are controlles by LibStation.
Refer to the HSC Configuration Guide for details on the LIBGEN process and also the
LibraryStation Configuration Guide.
The following description should only give you an idea what tasks are necessary to
complete the LibStation setup.
1. Update the HSC parameters by adding the LibStation definitions:
a) Include the location for the software license key:
LKEYDEF DSN('your.SLSPARM(LKEYINF1)')
b) Include the LSINIT statement:
LSINIT NETHOST(CLI1) COMMONSP(SPCSTOR)
COMMTYPE(TCPIP) TCPNAME(TCPIP) CREQLOG(YES)
HOSTID(SYSA) LSDEF('your.SLSPARM(LSDEFRO2)')
PDF('your.PDFRO2') PDFX('your.PDFRO2.PATH')
-
NETHOST states the HOSTID for LibStation that was defined during LIBGEN.
COMMONSP defines the default scratch pool name.
COMMTYPE(TCPIP) is used to connect ETERNUS CS HE.
HOSTID defines which LPAR is running the Library Station in a multi HSC
environment.
LDDEF is the location of your Library Station definitions, where you define pools
based on IP-addresses.
PDF and PDFX define the Persistent Data File (VSAM).
2. Create the member that represents the LSDEF statements:
SPNUM NUM(31) SPNAME(SPPVG01) IPADDR(192.50.35.133)
SPNUM NUM(32) SPNAME(SPPVG02) IPADDR(192.50.35.133)
i
Please note, that the subpool numbers which are defined here are HSC pool
IDs. They are not ETERNUS CS HE pool IDs.
3. Update the parameter member, that defines the scatch pools to reflect the entries in the
LSDEF definitions:
SCRPO NAME(SPPVG01),RANGE(P10000-P10499),LABEL(SL)
SCRPO NAME(SPPVG02),RANGE(P20000-P20299),LABEL(SL)
i
There may be other tasks necessary to complete the LibStation setup. For example
you may also include RACF security mechanisms.

5 ETERNUS CS HE on UNIX-type systems
5.1 Linux
5.1.1 EMULEX controller
The current EMULEX driver for SUSE Linux is 8.2.0 or higher. The driver is supplied
together with the Linux system.
5.1.2 Qlogic QLA2200F Controller
5.1.2.1
RedHat LINUX
Use of ETERNUS CS HE is supported as of RedHat Linux RHEL 4.
i
5.1.2.2
Neither a drive of the type Mammoth2 nor a VJUK library controller should be defined
on LUN0, otherwise only 1 LUN will be recognized in the RHEL 4/lpfc.
SuSE Linux 8.0 Professional
●
With the driver qla2x00, delivered with kernel 2.4.18, version 5,.38b16 is used.
Note:
The message in /var/log/boot.msg gives an incorrect driver version:
<6>scsi0 : QLogic QLA2200 PCI to Fibre Channel Host Adapter: bus 0 device 13 irq 9
<4>
Firmware version: 2.01.37, Driver version 4.46.5
●
BIOS version of the card: 1.54 or 1.61 or 1.72 or 1.77 (recommended). Particularly
intensive tests were conducted with the verrsions specified.
●
Linux kernel version: 2.4.18.
The Open Source code must be translated. For this the kernel sources must be read in.
The variable OSVER must have exactly the same name in the make file as in the
directory where the Linux source is located (e.g. linux).
153
Linux
ETERNUS CS HE on UNIX-type systems
●
The driver contained in the SuSE distribution has a error which prevents the tape from
being ejected from the drive. The LUN_NOT_READY from the drive is wrongly seen as
an error, and because of this the command is not executed. You can get round this
function call by commenting out qla2x00_check_sense in line 9964.
●
As the emulations from ETERNUS CS HE register themselves as SCSI-II drives, only
the first 8 LUNs are scanned in the kernel 2.4.18 (except for the IBM-3590 emulation).
Further drives must be added with the following command after every reboot:
echo "scsi add-single-device a b c d" > /proc/scsi/scsi
Where:
a
b
c
d
= Host adapter ID
= SCSI channel on the host adapter (for multi-channel HA)
= SCSI ID
= SCSI LUN
The following is a small Perl script which adds all LUNs from 8 to 32.
------------------------------------------------------------------------
#!/usr/bin/perl
$ILoop = 0;
for ( $ILoop = 8; $ILoop < 32; $ILoop++) {
system("echo \"scsi add-single-device 1 0 0 $ILoop\" >
/proc/scsi/scsi");
}
------------------------------------------------------------------------
From kernel version 2.4.19, an emulation running in ETERNUS CS HE is once again
automatically recognized with 32 LUNs.

According to the SCSI2 protocol, only 3 bits (0-7) should be used for LUNs. In the old QLOGIC driver version
this rule was not applied so strictly. In FSC version 4.47.11 this is handled more strictly. If more than 8 devices
are required, you should return to using the old drivers.
Linux
Data compression
On the host side, the compression in ETERNUS CS HE is activated for a (logical) device
with the mt command. For this to occur, the virtual drive must be configured with
Compression = Host.
Example:
# mt -f /dev/nst0 datcompression 2
compression ***
Compression on.
*** Activate
compression ***
Compression off.
*** Deactivate
***
Compression off.
*** Status display
The setting is only effective if the (logical) volume is unloaded before the mt. With an mt on
a loaded volume, the change in compression modes is not effective. This behavior depends
on ETERNUS CS HE.
–
–
–
–
–
For the drive emulation FSC/CentricStor, compression at the host is turned off by
default.
For the drive emulation EXABYTE/Mammoth2, compression at the host is switched on
as default.
The last activation or deactivation on the Linux host is still valid after the Linux reboot.
After the restart of the tape emulation (vtd), the default (see above) is again valid.
The compression at the host of the device node can also be configured in Linux with the
program stinit. In this case multiple or all drives can be configured at once without a tape
being mounted. A definition file must be created. This file has the following format:
manufacturer=FSC model = "CentricStor" {
mode1 blocksize=0 compression=0 # 0=not 1=compressed
}
The function call is then, for example:
stinit -f <DefFileName> /dev/st13 /dev/st14 /dev/st15 ...
Generally:
stinit [-f conf-file] [-h] [-p] [-r] [-v] [devices...]
The other Linux tape modes (/dev/st*, /dev/st*l, /dev/st*m, /dev/st*a) can
also be configured in this way.
155
Solaris
5.1.2.3
SuSE SLES 9.0
●
Neither a virtual drive of type Mammoth2 nor a VJUK robot controller should be defined
on LUN0, otherwise only 8 LUNs will be recognized by SLES 9/lpfc. Further drives must
be added with the following command after every reboot:
echo "scsi add-single-device a b c d" > /proc/scsi/scsi
Where:
a
b
c
d
●

SCSI channel on the host adapter (for multi-channel HA)

Rebooting a server or reloading the FC driver (Qlogic or Emulex) on a server connected
to ETERNUS CS HE and running SLES 9 SP3 will cause the drive to be rewound. This
interrupts I/O operations running on other servers which are connected to the same
drives.
We recommend the installation of SuSE update
udev-021-36.63.i586.rpm/udev-021-36.63.x86_64.rpm
in order to prevent this problem.
5.2 Solaris
5.2.1 Requirements
●
Versions 7, 8, 9 and 10 are supported (2.6 on request).
●
To operate tape drives in Solaris V8, at least the following patches must be present on
the system:
108725-09, 108528-15, 108987-09, 111111-03 and 112396-02.
Without these patches there will delays in defining drives, especially under Tivoli.
●
156
The EMULEX LP9802DC FC controller may not be used.
Solaris
5.2.2 Useful commands and URLs
●
The current patch level of the system can be found with the command: uname –a.
The result is, for example:
SunOS HAI 5.8 Generic_108528-09 sun4u sparc FJSV,GPUU
In the example, patch level 108528 is installed.
●
For information about more recent patches, visit the SUN internet site at
http://www.sun.com ➟ Support ➟ Patches ➟ Recommended & Security Patches.
You can get information here on which cluster patches are current for the systems.

●
Service Partner Portal on the extranet:
https://partners.ts.fujitsu.com/com/service/Pages/default.aspx
5.2.3 Important settings and information
●
You must be operating with the tape driver st.
●
Solaris does not permit two FC controllers to bind to the same WWPN. This is also not
permitted in ETERNUS CS HE because it would otherwise bind two different device
nodes to the same logical device. This is not supported by the backup tools.
●
If a new zone is defined and activated in a fabric, all Solaris systems connected to this
fabric will report an error. The file /var/adm/messages gives this message, for
example:
WARNING: lpfc0:120:Device disappeared, nodev timeout: …
●
On Solaris systems reservation problems can occur with the emulations. These are
caused by the chktapecln daemon, which runs every 6 hours.
You must proceed as follows to disable this daemon:
Ê
cp /etc/opt/FJSVmadm/hardmontab /etc/opt/FJSVmadm/hardmontab.org
Ê
Delete the following line from the /etc/opt/FJSVmadm/hardmontab file:
2160 /usr/sbin/FJSVmadm/chktapecln
Ê
Then call /usr/sbin/FJSVmadm/swhardmon update so that the modifications
become effective.
157
Solaris
●
On Solaris systems (test system Solaris 9 with LP10K) with the EMULEX lpfc driver
6.30g the device nodes are not recognized as tape volumes, though LUN recognition
is correct (see /var/log/messages). This applies to all ETERNUS CS HE emulation
types.

After Solaris reboot perform HBA reset on Solaris, e.g.
# /opt/HBAnyware/hbacmd reset 10:00:00:00:c9:45:70:b7
With the latest EMULEX lpfc driver 6.11.cx2 released by FSC/FTS the problem "No
such device" after Solaris reboot does not occur any more. This also applies to the legacy versions 6.01f.

5.2.4 Driver for EMULEX
The driver lpfc must be installed. It normally consists of the files
/kernel/drv/lpfc and
/kernel/drv/lpfc.conf.
The driver is also on the supplement CD.
The firmware is copied to the directory /opt/SMAW/SMAWfirm. The firmware is loaded with

information see section “Persistent Binding” on page 165 and the example of the file

159
Solaris
5.2.5 Installation and configuration of QLA2310F SUN
First of all the required updates and patches for Solaris must be installed. To do this you
load the SAN_X.X.X_install_it.tar.Z package from http://www.sun.com/storage/san.
This package contains all the updates and patches and a script for automatic intallation and
for automatic loading of new updates/patches. It also installs the qlc driver.
The qlc driver recognizes the installed QLA2300F SUN HBA and writes some information
to the Systemlog, but it does not recognize any drives. The QLA2300 driver from Sun is
needed. You will find this on the QLogic web site. This package enables you to install the
qla2300 driver with the /kernel/drv/qla2300.conf configuration file. This driver
writes some entries to the /etc/driver_aliases file. These must be removed and the
line qla2300 "pci1077,2300" entered.
The qlc driver must now be removed: rem_drv qlc. The qla2300 driver is then added:
add_drv -c scsi -i "pci1077,2300" -n qla2300. A reconfiguration reboot is then
required: reboot ---r.
To ensure that the same device nodes are always used, persistent binding must be configured. To do this you load the SANblade CLI for Solaris SPARC package from the web site
containing the driver package. Following installation you can configure the driver using the
scli program. This program finds the installed HBA. It can display various attributes and,
among other things, configure persistent binding. You must insert the target ID which is
entered in the st.conf in the appropriate place. The program writes the corresponding
information to the /kernel/drv/qla2300.conf file. After another reconfiguration reboot
the recognized drives should be contained in the Systemlog with the correct target ID.
i
A LUN can also be locked by means of an entry in the driver configuration file
qla23000.conf, for example:
ba0-SCSI-target-id-0-lun-0-disable
160
Solaris
5.2.6 Tape driver st
i
The more recent controller CDs install this tape type already in the st.conf.
To ensure that tape devices can be operated with a LUN <> 0, the file
/kernel/drv/st.conf must be extended as follows:
1. Then the entry for the new device type of the virtual tape drive CentricStor of FSC must
be made in the tape-config-list (the entry for a Magstar drive is shown below):
tape-config-list=
"FSC
",
"IBM
03590B",
centrs
X03590B
=
=
"CentricStor",
"PXT1",
"centrs",
"X03590B";
1,0x36,0,0x18619,1,0x00,0;
1,0x24,0,0x61c439,1,0x00,0;
2. Next, the LUNs to be used from this host must be specified for the connected targets
(ICPs):
#
#
#
#
name="st"
name="st"
...
name="st"
#
#
#
name="st"
name="st"
...
name="st"
#
#
#
#
#
name="st"
name="st"
...
name="st"
STAR-ICP0:

ctrl-15 :
4th 16 LDs
STAR-ICP1:
2nd 16 LDs
ctrl-14 :
2nd 16 LDs
Following a reboot, the ETERNUS CS HE drives are then recognized and the corresponding device nodes created.
161
Solaris
i
The target and LUN are specified in hexadecimal form for the device nodes, i.e.:
– 53 becomes 0x35
– 63 becomes 0x3f
In the case of Qlogic HBAs, the st.conf file alone is not decisive for creating the
device node, i.e. the system also creates device nodes when there is no LUN
entry specifying this in st.conf. This means that no LUNs can be masked out in
this way, either. Instead, this must be done using the qla2300.conf file (see section “Installation and configuration of QLA2310F SUN” on page 160).
3. It is advisable to save the modified st.conf file as st.conf.save, for example,
because certain tools will overwrite the file automatically.
The section “Contents of the file st.conf for Solaris” on page 173 shows an example.
After a reboot, the ETERNUS CS HE drives are recognized.
If there are further targets in the FC loop (e.g. other ICPs, disks or tape devices) further
target numbers appear. The file st.conf must then be appropriately extended. EMULEX
drivers are configured via the file /kernel/drv/lpfc.conf in the same way as the target
numbers of the FC targets are shown in st.conf (previously SCSI IDs).
162
Solaris
5.2.7 Device nodes
Solaris creates symbolic links for recognized tape units in /dev/rmt which point to the
device nodes in the /devices/ directory:
lrwxrwxrwx 1 root root 52 Apr 16 14:09 0bn

– 1f is LUN=31 in hex format,
– c: compression mode,
– b: Berkley mode,
– n: no rewind
together these items describe the logical device V01F on ICP0 (see vtls.conf [ ld ]),
The numbers in /dev/rmt (here 0 - 49) are selected by Solaris depending on the configuration.
– 0-31 are the second 32 LDs on ICP0
– 32-47 are the second 16 LDs on ICP1
– 48-49 are the two native Magstar drives via the targets 0 und 1
i
If the two Magstar drives appear at the start, all the link numbers are shifted. In this
case:
– 0-1 would be the two native Magstar drives via targets 0 und 1
– 2-33 would be the second 32 LDs on ICP0
– 34-49 would be the second 16 LDs on ICP1
163
Solaris
To avoid unwanted accesses to external LDs, it is thus necessary at this point to create
symbolic links with more meaningful names (with ICP and LD name in ETERNUS CS HE)
for those LDs that are to be accessed by this host. (An example of a more meaningful name
would be vt for virtual tape):

Wherever possible you should use the same nomenclature on the other hosts. Only these
links should be entered in the NetWorker configurations subsequently.
There is a further advantage if the FC controller is reconfigured on a host. In this case all
device nodes (controller numbers) are changed on the right-hand side, and the symbolic
links on the left-hand side point to invalid destinations. In other words, although all the links
must be recreated, the entries in the host applications (e.g. NetWorker) remain unchanged.

5.2.8 Persistent Binding
If a device with SCSI is to be operated in Solaris via FC, a unique ID (SCSI ID) must be
assigned to each target (i.e. the external FC controllers of the ICPs in this case). There are
a number of ways for making this assignment. However, the only secure method is to use
persistent binding, because with the automatic procedure the assignment might go wrong in
a reboot or a reconfiguration. A line is entered in lpfc.conf for each ETERNUS CS HE
controller to be operated from Solaris:
fcp-bind-WWPN="10000000c922e06b:lpfc0t53";
The 16-position number is the WWPN, the 'World Wide Port Name' encoded in the FC card
in ETERNUS CS HE.
If the host does not use an ICP logical device, no persistent binding should be entered for
its FC adapter.
An overview of the WWNs for all adapters of the ICP can be shown with:
GXCC - Function bar: Administration ➟ Show WWN’s
i
To show the WWNN and WWPN for an individual host adapter use:
[GXCC object function ➟ ICP… ➟ Show Details]; Host adapter object information
Alternatively, you can find out the number from Solaris in /var/adm/messages after
booting, or in Sinix-Z through /etc/fc/fclog | grep "own port_name", likewise after
booting.
Rules
●
The 0 in lpfc0t53 must address the appropriate FC controller.
●
The 53 here is the assigned SCSI-ID, which must be cross-matched with st.conf
(target=53).
●
It is advisable to select a target number outside of the usual range of 0-16 in order to
avoid conflicts with normal tape devices. For example, this avoids a situation where a
normal tape unit on a different (SCSI) controller is checked on the numerous ETERNUS
CS HE LUNs.
●
If several target systems are linked, the target ID must increase over several FC
controllers. (e.g. lpfc0t53, lpfc0t54, lpfc1t55 - but not lpfc0t53, lpfc1t54,
lpfc0t55).

Its own FC controller must be logged in on the switch as the F-port. You can check this on
the switch by logging yourself in on the switch through telnet.

5.2.10 Solaris systems in server farms
During a reboot, Solaris scans all LUNs with reserve/release. On server farms this feature can
occasionally cause problems with other host systems. A solution to this problem is to mask
the LUNs in the st.conf file given that Solaris will only scanned the LUNs defined as such
(see section “Contents of the file st.conf for Solaris” on page 173).

Setup FCP persistent bindings,
fcp-bind-WWPN binds a specific WorldWide PortName to a target id,
fcp-bind-WWNN binds a specific WorldWide NodeName to a target id,
fcp-bind-DID binds a specific DID to a target id.
Only one binding method can be used.
WWNN, WWPN and DID are hexadecimal values.
WWNN must be 16 digits with leading 0s.
WWPN must be 16 digits with leading 0s.
DID must be 6 digits with leading 0s.
The SCSI ID to bind to consists of two parts, the lpfc interface
to bind to, and the target number for that interface.
Thus lpfc0t2 specifies target 2 on interface lpfc0.
NOTE: Target ids, with all luns supported, must also be in sd.conf.
scan-down must be set to 0 or 1, not 2 which is the default!!

no-device-delay [0 to 30] - determines the length of
the interval between deciding to fail back an I/O because there is no way
to communicate with its particular device (e.g., due to device failure) and
the actual fail back. A value of zero implies no delay whatsoever.
Cautions: (1) This value is in seconds.
(2) Setting a long delay value may permit I/O to build up,
each with a pending timeout, which could result in the exhaustion of
critical Solaris kernel resources. In this case, you may see a fatal
message such as
PANIC: Timeout table overflow

# 36 pages, which isn't nearly enough for LPFC when running IP. Typically,

5.2.13 Extensions for Data Protector and SolarisTivoli
For Data Protector the size of the shared memory must be extended.
Ê
In the file /etc/system the entry:
set shmsys:shminfo_shmmax=0x7FFFFFFF
This change has no negative effect on the system.
Ê
Then the system must be rebooted.
5.2.14 Extensions for NetBackup
For NetBackup the sg driver must be installed in accordance with the NetBackup Media
Manager Device Configuration Guide from Veritas.
5.2.15 Sun StorEdge SAN Foundation Software (SFS/Leadville)
5.2.15.1
General
The Leadville driver from SUN StorEdge SAN Foundation Software (SFS) can also be used on
Solaris systems as an alternative to the Emulex FibreChannel driver lpfc and the Qlogic FibreChannel driver qla. For this purpose, the SAN Foundation Software from Sun must be
downloaded1 for Solaris 8/9. You must register to do this. In Solaris 10 (1/06) and higher,
the software is already part of the operating system.
The benefits of the SFS/Leadville driver lie in the flexible administration of SAN devices in
general, and in the integrated multipath and load balancing softrware MPxIO for RAID systems. A permanent binding of the targets and LUNs as with the lpfc/qla driver is no longer
required.
!

CAUTION!
SFS/lpfc mixed operation has not been released.

In addition to the SFS software, the Emulex FibreChannel Device Management Utility
EMLXemlxu must also be installed. This utility permits both administration (firmware/Fcode
update) and diagnostics. The current version of the utility can be obtained free of charge
from the Emulex websites.
The SMAWdevsp software package must also be installed. This package is contained on the
Control DVD. The current version 2.0B301 can be obtained from the websites for service
partners (Home ➟ Partner Portal ➟ Service partner portal ➟ PRIMEPOWER ➟ Software ➟
Documents ➟ control DVD Products ➟ Solaris Platform ➟ FSC Basic Extensions ➟ Updates).
Installing this packages results in the /kernel/drv/st.conf file for the released tape
drives and for the drive emulations of ETERNUS CS HE being modified.

178
Solaris
The following configuration files must be adjusted for SFS/Leadville operation using
ETERNUS CS HE:
●
/kernel/drv/emlxs.conf
link-speed=1/2/4
It is advisable to set a fixed speed for the FibreChannel connection.
topology=2
The connection of the Open System Server to the ICP of
ETERNUS CS HE is always implemented via FibreChannel switches. Point to Point topology must therefore be set permanently.
The default value should be retained for all other parameters. If HBA-specific settings
need to be made - e.g. when RAID systems are connected directly - the HBA instance
must be set before the parameter.
Example: emlxs0-topology=4;
●
/kernel/drv/fp.conf
Settings are required in this file only if ETERNUS CS HE tape LUNs are to be masked.
This feature is only available in Solaris 10 (Patch 119130-22) and higher.
Example
4 virtual tapes (LUNs 0-3) are configured on one port of an ETERNUS CS HE ICP. 2
servers are now connected to this port via a FibreChannel switch. Server 1 should see
all 4 tape LUNs, but server 2 only tape LUNs 2 and 3. From the viewpoint of server 2,
tape LUNs 0 and 1 must therefore be entered in a blacklist.
pwwn-lun-blacklist=
"510000f010fd92a1,0,1",
"510000e012079df1,1,2";
This entry means that LUNs 0 and 1 on the target 510000f010fd92a1 and LUNs 1 and
2 on target 510000e012079df1 cannot be accessed after a reboot.
●
/kernel/drv/st.conf
After Version 2.0B20 of the SMAWdevsp package has been installed, no further settings
are required. It is important that the following parameter is set for an emulation running
in ETERNUS CS HE:
Xtor=1,0x36,0,0x18619,1,0x00,0;

Example of migration from lpfc to SFS/Leadville
The example below illustrates migration from lpfc to SFS/Leadville on a Primepower 450
with Solaris 9. The virtual tapes rmt/0-3 belong to a VJUK emulation, the virtual tapes
rmt/4-7 to a VDAS emulation.

This output shows that an HBA c4 is connected to a FibreChannel switch (fc-fabric
in the Type column). In the case of a directly connected storage device, fc-privat
would be contained in the Type column. The reference of HBA c4 to the physical node
is contained in the /dev/cfg directory.

In this case the WWPN 10000000c9553c6e represents the WWPN of the ETERNUS
CS HE ICP ports. 16 Tape Devices (LUNs 0-15) and one Changer Device are configured
on this ETERNUS CS HE port.
At this time the ETERNUS CS HE configuration is consequently visible to Solaris, but
not yet activated (Occupant unconfigured).
The following command is issued to activate this configuration on the target

The 8 tape LUNs (/dev/rmt/16 - 23) of the emulation of the type FSC/CentricStor
which were previously visible using the lpfc driver as /dev/rmt/0 - 7 can now be recognized again.
The changer device is not displayed when luxadm display <WWPN> is used.
Here the relevant device node is contained in the /dev/scsi/changer directory.

Solaris
The disadvantage is that all LANs on this target are now visible. With Solaris 10, these
LUNs which are not required can be masked by means of the blacklist (see above). This
is not possible with Solaris 8/9. As an alternative, these LUNs can be set offline using
the following command.
Example: # luxadm -e offline /dev/rmt/8n

Familiar problems
●
In the case of a multipath connection to a tape LUN, the reservation is not canceled by
the mt -f /dev/rmt/x forcereserve command.
●
When a luxadm display /dev/rmt/16 is executed for a tape which is currently
being used, the following error message is issued:
Error: SCSI failure. - /dev/rmt/16
5.2.16 HBAnyware
With ETERNUS CS HE Version 5.0 the HBAnyware Command Line Interface can be used
to maintain the internal FC infrastructure.
For additional information please refer to following URL:
http://www-dl.emulex.com/support/utilities/hbanyware/41/hbanyware.pdf
!
CAUTION!
Please contact our Second/Third Level Support before you modify anything with our
FC HBAs!

HP-UX
5.3 HP-UX
5.3.1 General
●
HP-UX B11.00 is required for connection to ETERNUS CS HE.
(there are two older FC cards, A6684A with HSC-EISA and A6685A with HP-HSC
Interface, which are already supported by HP-UX B10.20. These have not yet been
tested. Both cards support Fabric Login.)
●
The patch PHKL_23939 from http://www.hp.com is required for connection to
ETERNUS CS HE. If the patch is not in use, the machine logs itself on and off with every
open/close on the FC switch. Then the klog.msg of the ICP constantly shows
messages.
●
Device nodes can only be generated if they can be accessed from LUN 0 without interruption.
5.3.2 Restrictions
The system only supports 8 LUNs per partner WWN.
The system must not be connected to an FC switch with the 8 domains.
i
5.3.3 Useful commands:
–
–
–
–
–
–
–
sam (configuration network, setting up device nodes etc.)
swinstall, swverify (software installation)
fcmsutil /dev/td0
ioscan (scanning the I/O ports – shows ETERNUS CS HE)
lsdev
xstm

HP: Migration to Fabric
196
HP-UX
5.3.5 Device nodes
By default, device nodes are created as compressed. However, Mammoth2 and generic
SCSI emulations create nodes which are not compressed. In these cases compression
should be switched on in the ETERNUS CS HE configuration.
/dev/rmt/c6t0d0BESTb
...
!
CAUTION!
If the port on the switch or the switch itself changes then the devices must be regenerated with sam. In the process the controller number is raised
(/dev/rmt/c6t0d0BESTb -> /dev/rmt/c7t0d0BESTb).
197
IBM-AIX
5.4 IBM-AIX
5.4.1 Restrictions
The standard driver OST (Other SCSI Tape) generates device nodes, which cannot
compress.
In CS V2.1 or higher, compression can be turned on explicitly for an LD.
i
5.4.2 Important settings and information
●
●
3590 Emulation on the ETERNUS CS HE side:
–
LAN libraries:
LUN 0 must always be defined with FSC/CentricStor, the other LUNs with
IBM 03590.
–
SCSI libraries:
Define robotics on LUN 0, all emulations with IBM 03590
–
Drives with the emulation FSC/CentricStor are entered in AIX as other scsis tape.
–
Drives with the emulation IBM 03590 are entered as IBM 3590 Tape Drive and
Medium Changer.
The Atape must be used in AIX.
The driver for the drive 3590 (Atape.7.0.3.0.bin or newer version) can be loaded from
ftp://ftp.software.ibm.com/storage/devdrvr/AIX/
The installation of Atape.driver can be checked with:

198
●
When the Mammoth2 emulation is used configuration can take place from LUN 0.
●
Device nodes can only be generated if they can be accessed from LUN 0 without interruption.
●
In AIX there is no persistent binding as AIX addresses the devices directly via the
WWN.
●
IBM-AIX
When hardware scanning takes place with cfgmgr and VJUK the following message is
issued:

5.4.4 Configuration of the drives
Ê
First, delete any drives present drives with smit ➟ Devices ➟ Tape Drive
➟ Remove a Tape Drive.
Ê
Connect the drives or link them with ETERNUS CS HE.
Ê
Reboot the system with reboot -- -r. If the system cannot be rebooted, you can, for
example, delete the tapes with the following script:
#!/usr/bin/ksh
lsdev -Cc tape | awk '{ print $1 }' | while read RMT; do
rmdev -l $RMT -d
done
After this, recreate the configuration automatically with cfgmgr.

6 ETERNUS CS HE in Windows
The following restriction applies for the Windows operating system: A maximum of 32 LUNS
can be released for Windows in ETERNUS CS HE. If more LUNS are configured for
Windows in ETERNUS CS HE, it can happen that Windows sees all the devices but does
not load any tape device drivers.
In Windows 2003 logical devices are supported with the FC port driver 5-2.22a8 64.
6.1 Configuration
Recognizing more than 8 LUNs
●
Change to
HKEY_LOCAL_MACHINE ➟ SYSTEM ➟ CurrentControlSet ➟ Control ➟ ScsiPort
➟ SpecialTargetList with REGEDIT.
●
Define a new key which corresponds to the emulation inquiry. Setup:
Vendor 8 characters
Device 16 characters
Version 1 character
Blanks are shown as _ .
Example
EXABYTE_Mammoth2________v
FSC_____CentricStor_____8
●
Define field. LargeLUNs: REG_DWORD: 0x1
●
For IBM 3590E emulation, an entry is not necessary because the emulation has set the
HiSupport Bit.
205
Important settings and information
ETERNUS CS HE in Windows
6.2 Important settings and information
●
Windows can only see drives of one type on ETERNUS CS HE.
●
When booting with QL2200, the following error messages are written regularly in the
system event log:
"The driver has found a controller error on \Device\SCSI\ql2200 or
ql22001" with the event data: "80110000, f0130000, f0210000,
f0140000, f0170000"
This is normal behavior and occurs, for example, when there are changes in the FC
topology.
●
In order to ensure that the specified block size of 192 KB is maintained in Windows NT
and Windows 2000 with the Qlogic FCC Miniport Driver for QLA2200 adapter for
Exabyte Mammoth-2, you must ensure that the registry.
HKEY_LOCAL_MACHINE ➟ SYSTEM ➟ CurrentControlSet ➟ Services ➟ Ql2200
➟ Parameters ➟ Device
has a high enough setting for the value MaximumSGList:REG_DWORD.
The default of 0x21(33) in some newer driver versions (e.g. 8.1.5.10 NT4 IP or W2K
IP, FW Version 2.02.01 TP/IP) gives an unsuitable block size of only 128 KB; this
rules out volume-sharing with other systems such as Linux.
If MaximumSGList:REG_DWORD is set to 0x41(65), the maximum block size is set
to 256 KB. Windows must be rebooted after the change. If the NetWorker volume is
labeled under MaximumSGList:REG_DWORD 0x41(65), it is then described with the
specified block size of 192 KB for Exabyte Mammoth-2.
●
Before the operating system is updated the device drivers on the host for the HBAs,
tape devices and robotics (jukebox/media changer) on the fibre channel must be
backed up with ETERNUS CS HE for safety’s sake, and after the operating system has
been updated any automatic driver update that takes place must be verified.
Reason: In Windows 2003 it has been observed that after an update the EXABYTE
Mammoth2 tape device driver installed previously has been replaced by a MICROSOFT
Mammoth2 tape device driver which was not compatible with the volumes written previously. Consequently ETERNUS CS HE backups, for example, can no longer be used
with the Microsoft MM2 driver 5.2.3790.0 (01.10.2002)!
●
206
For the emulations IBM 3590 or LTO-2, the corresponding drivers must be installed.
These can be downloaded from http://www.ibm.com/support/us/en/.
7 ETERNUS CS HE on NAS systems
7.1 General information on saving using NDMP
ETERNUS CS HE offers implicit cloning of tapes, which means that a copy of NDMP
backups can be created without placing an additional load on the NAS system .
7.2 NetApp
7.2.1 Prerequisites
Tests were performed in the following system environment:
●
NetApp FAS3020 with operating system version ONTAP 7.2.4 and FC controller
Qlogic 2312
●
Connection of NetApp via FC switch
7.2.2 Restrictions
NetApp filers support up to 64 tape devices. Consequently zoning and other suitable
measures must be used to ensure that the NetApp filer as far as possible only sees the tape
devices intended for it, but in no case more than a total of 64 tape devices.
Because of a restriction in the ONTAP operating system of the NetApp filers, it must also
be ensured that LUN 0 on all the ICP controllers which are visible for NetApp filers is set to
an emulation other than Mammoth2.
207
NetApp
ETERNUS CS HE on NAS systems
IBM 3590E, Mammoth 2 and 9840B are tape emulations which have been tested successfully.
For performance reasons you are recommended to select the HOST setting (compression
by the host) for the GXCC configuration function Logical Drives in the Compression form; the
ON or OFF setting can also be used.
7.2.4 Useful commands
sysconfig -av
sysconfig -t
reboot
show hardware configuration
show tapes
reboot NetApp system
7.2.5 Update Installation in ETERNUS CS HE
NetApp filers crash during update installation of ETERNUS CS HE
With the current status of the NetApp filers, deactivation commands must be entered before
you reboot the ICP so that the filer survives this reboot. Activation is required after this
reboot.
208
Celerra
7.3 Celerra
7.3.1 Prerequisites
Tests were performed in the following system environment:
●
Celerra Datamover NS700G with operating system version DART 5.5.24.204 (or
NS20G with DART 5.5.32.4)
●
Connection of Celerra via FC switch
7.3.2 Restrictions
Celerra only permits the addr- designation to identify NDMP tape devices, not the name designation. This is a general restriction of the DART operating system.
Example
The server_devconfig server_2 -list -scsi -nondisks command on the
Celerra Control Node supplies the following output (abbreviated here):
server_2 :

7.3.3 Configuration
7.3.3.1
Configuration in ETERNUS CS HE
IBM 3590E, Mammoth 2 and 9840B are tape emulations which have been tested successfully.
For performance reasons you are recommended to select the HOST setting (compression
by the host) for the GXCC configuration function Logical Drives in the Compression form; the
ON or OFF setting can also be used.
209
Celerra
7.3.3.2
Configuration of Celerra
It is generally recommended that the block size for NDMP backups should be increased
from the default value of 128k to 256k, the maximum value possible in ETERNUS CS HE.
Under certain circumstances the value to be set depends on the block size used by the
backup application, see below. The block size is set by issuing the command below for each
Data-Mover on the Celerra ControlNode
server_param <data_mover_n> -facility NDMP -modify bufsz -value 256
and rebooting the Data-Mover.
The default values can be used for the other settings for the Data-Mover.

8 Tape management systems
8.1 General
General information is provided below concerning the use of ETERNUS CS HE together
with tape management systems, e.g. NetWorker, NetBackup.
The tape management systems currently supported can be found in the support matrix for
ETERNUS CS HE:
https://partners.ts.fujitsu.com/teams/cpc/Support%20Matrix/ETERNUS_CS_
Support_Matrix.xlsx
The following robotic emulation types (virtual library services) are available with
ETERNUS CS HE:
●
VDAS: emulation of DAS/ACI Server
●
VACS: emulation of ACSLS Server
●
VJUK: emulation of SCSI jukebox
The following tape drive emulation types (logical drives) are available with ETERNUS CS
HE:
●
IBM/IBM 3590E1A
●
STK/T9840B
●
IBM/LTO Ultrium 2/4
●
EXABYTE/Mammoth2
●
FSC/CentricStor
The tape drive types and robotic types which are supported by the tape management
systems are listed in the support or compatibility information for the products.
Since ETERNUS CS HE emulates real hardware tape drives, SCSI jukeboxes and tape
libraries, most of the configuration steps needed are identical to the ones needed for real
hardware. Differences are described in the sections below.
213
General
Tape management systems
Consult the tape management systems documentation for a description of how to configure
and use the tape drives and robotics. Most of the systems provide command line or
graphical interfaces for this purpose.
Before configuration of the tape management system can be performed, all tape devices
and robotics must be accessible on the host systems. Check this with the commands and
interfaces provided in the operating system, see chapter “ETERNUS CS HE on UNIX-type
systems” on page 153 for more information.
If the VDAS or VACS emulation is used, a network connection between ETERNUS CS HE
and the host system must be established. This can be checked with the ping command.
Furthermore the name of the host system must be resolvable on the VLP/IUP/VTC of the
ETERNUS CS HE, and the name of the VLP/IUP/VTC must be resolvable on the host
system. Check this using the nslookup command if DNS is used, or search for the host name
in the hosts file.
The maximum IO block size supported by ETERNUS CS HE is 256 KB. Check the
operating system and tape management system documentation for which IO block sizes
are supported. Changes in the default configuration of the management systems might be
needed.
i
The operations import and export of volumes are not supported by ETERNUS CS
HE.
ETERNUS CS HE provides various sizes for logical volumes. The standard value is 900
MB, but other values between 2 GB and 200 GB are selectable. If compression is performed
by ETERNUS CS HE, the amount of data which will fit on a logical volume increases
accordingly (the standard compression ratio for tapes is 1:2; compression with ETERNUS
CS HE is at least as good.). Given the total capacity, there is a simple relationship between
the size and the number of logical volumes: The larger the volumes are, the less volumes
are required, and the smaller the volumes are, the more volumes are required.
The larger the logical volumes are, the more the following negative effects increase:
●
Logical volumes may match physical volumes less well, and appending volumes may
increase the amount of wasted space on physical tape.
●
The utilization of the Tape Volume Cache (TVC) may decrease.
●
The restoration of even a small amount of data may require a large amount of data to
be read back into the TVC.
The number of virtual volumes should be calculated carefully since maintaining very large
numbers of volumes might be a very expensive process which consumes a great deal of
resources on the host systems.
214
NetWorker (EMC and Fujitsu)
8.2 NetWorker (EMC and Fujitsu)
8.2.1 Documentation
Information about NetWorker can be found in the following documentation:
●
Fujitsu NetWorker on the Internet:
https://ts.fujitsu.com/products/software/management/storage/networker/index.html
●
Fujitsu NetWorker Manuals:
http://manuals.ts.fujitsu.com

up_basics/Pages/default.aspx
●
EMC Networker in EMC POWERLINK (personal account required):
https://powerlink.emc.com
8.2.2 Configuration
As a preparation step to configure ETERNUS CS HE, the NetWorker command inquire
should be invoked. The inquire command provides a list of all attached devices with their
device node, inquiry string, serial number, and other information. This list is very useful in
order to find out what ETERNUS CS HE devices are mapped to what device nodes.
Like a real SCSI jukebox or tape library, ETERNUS CS HE is configured in NetWorker using
the jbconfig command. jbconfig creates a jukebox resource along with device resources for
the virtual drives to store all configuration and status data related to the respective
ETERNUS CS HE system. If the VJUK emulation is used, proceed in the same way as for
real SCSI jukeboxes (see the NetWorker Administrator's Guide).
When a VDAS or VACS jukebox is configured, jbconfig asks for the following information:
●
Configure Mode: enter the choice for configuring an STL silo
●
Silo type: depending on the ETERNUS CS HE robotic emulation chosen:
– VDAS: enter the choice for DAS/ACI
– VACS: enter the choice for ACSLS
●
Jukebox Name: enter a name of your choice. Only restriction: there is not already another
jukebox with this name.
●
Silo Server: IP node name of the VLP/IUP/VTC in the external LAN.
215
●
STLI interface library:
– Fujitsu NetWorker:
– VDAS: enter libstlaci_cs.so, except in firewall environments where libstlaci_fw_cs.so
is used
– VACS: enter libstlstk_cs.so
– EMC NetWorker: confirm the prompted default value
●
The other information requested by jbconfig must be answered in the same way as for
real tape libraries.
Some values of the NetWorker Device Resource must be adapted to ETERNUS CS HE configurations:
●
Device block size
The maximum IO block size supported by ETERNUS CS HE is 256 KB. The default
block size used by NetWorker for the tape drive type 3590 Magstar is higher than this
value. All NetWorker hosts in a data zone (i.e. the NetWorker server and the server's
storage nodes) must use the same block size. For every virtual drive the block size
attribute of all device resources must be changed to the same value.
●
CDI
Set CDI to Not used in the device resources of all ETERNUS CS HE logical drives.
This is because virtual tape drives in ETERNUS CS HE do not require cleanings or
tape-drive-specific error recovery. On the other hand, CDI enabled can cause
NetWorker to malfunction because the SCSI interface of virtual tape drives in
ETERNUS CS HE does not completely comply with the SCSI interfaces of real tape
drives.
NetWorker supports two functions which allow more powerful use of ETERNUS CS HE:
●
Prefetching
Prefetching is a feature which is important for recover commands. It accelerates
NetWorker recover commands from multiple volumes if not all volumes are in the TVC
of ETERNUS CS HE and have to be read from physical tape. The prefetch feature is
implemented as a script which is invoked by the NetWorker notification mechanism and
which tells ETERNUS CS HE to read the required logical volumes from physical tape
into the TVC in advance so that they are already back in the TVC when NetWorker
issues the mount command. It must be observed that the prefetch feature accelerates
mounts from the 3rd volume on; it has no effect on the mount times for the 1st and 2nd
volumes.
Templates for the prefetch scripts (for EMC NetWorker as well as for Fujitsu NetWorker)
and a readme about how to install and configure the script are available at ftp:ftp.fujitsusiemens.com/pub/nsr/add-on.
216
●
Fast Mount
If NetWorker mounts a logical volume for relabeling and the logical volume is not in the
TVC, ETERNUS CS HE reads the logical tape back from physical tape into the TVC,
which is useless since NetWorker will immediately invalidate all this data by relabeling
the tape. In detail, things are more complicated: NetWorker actually reads some tape
data even in the case of (re-)labeling. What NetWorker reads are the first 2 blocks on
the tape which hold the volume label. NetWorker reads the label blocks in order to avoid
overwriting valid backup data by mistake. These two label blocks fit into a portion of data
at the beginning of a logical volume which is TVC-resident, i.e. which is never purged
from the TVC. So access to the NetWorker label never requires restoration of a logical
volume from physical tape.
FastMount is an additional function in the silo interface between NetWorker and
ETERNUS CS HE. In ETERNUS CS HE, FastMount is implemented in such a way that
volumes are mounted without recovering any data from physical tape. If FastMount is
available, NetWorker mounts a volume to be (re-)labeled by means of FastMount rather
than using the ordinary mount function.
The FastMount feature is available for the VDAS and VACS emulations together with
Fujitsu NetWorker. EMC NetWorker supports this feature with the VACS emulation only.

8.3.2 Installation
Perform a standard NetBackup installation as referenced in the NetBackup Installation
Guide for the NetBackup version you use.
Example from Solaris
218
–
To install NetBackup, call install on the CD.
–
All queries to the installer are self-explanatory.
–
Approx. 200MB of disk space is required.
–
Default installation path is: /opt/openv/….
–
NetBackup is started by a S77…-script or with ‘initbprd’.
–
NetBackup is stopped with a K77….-script or with ‘bp.kill_all’.
8.3.3 Configuration
●
Recommended configuration tools: bpadm, jnbSA and jbpSA.
●
Storage Units must be configured first, then the devices.
●
The device nodes must be cbn nodes:
c = optional compression.
b = BSD option which is needed explicitly for Solaris.
●
Classes must be defined for the backup jobs.
●
To define devices under NetBackup follow the instructions of the Device Config Guide
for NetBackup version and Operating System.
Notes / Features
●
As of Version 4.5 the Motif interfaces xbpadm, xbpmon, xvmadm and xdevadm are no
longer supported. The Java interfaces jnbSA and jbpSA are recommended, and also
the command line and the menu-based program bpadm.
●
NetBackup works with standard UNIX tape access: mt / tar.
●
From Version 4.5 the term Class is no longer used and is now interpreted as Policy.
●
The Leadville driver from SUN StorEdge SAN Foundation Software (SFS) can also be used
on Solaris systems (see section “Sun StorEdge SAN Foundation Software
(SFS/Leadville)” on page 177).
●
/kernel/drv/st.conf on Solaris (see section “Contents of the file st.conf for Solaris”
on page 173) must be adapted appropriately for ETERNUS CS HE. After Version
2.0B20 of the SMAWdevsp package has been installed, no further settings are required.
It is important that the following parameter is set for an emulation running in ETERNUS
CS HE:
Xtor=1,0x36,0,0x18619,1,0x00,0;
●
On Solaris, the sg driver from Symantec must also be installed. See: Media Manager
Device Configuration Guide from Symantec.
●
/opt/openv/volmgr/bin/robtest for diagnosing devices and acs interface
(see System Administrator’s Guide, Appendix B, Robotic Test Utilities)
●
In the NetBackup ‘inventory’, VACS only returns tapes which are already known to
VACS or have already been accessed. All media servers connected to VACS also need
an ssi client, i.e. for Windows media servers connected to ETERNUS CS HE, Libattch
software needs to be installed.
219
●
In supporting ACS robot interfaces, ensure that only up to 20 spaces for drives are
supported per panel. This restriction must be observed in the configuration of a virtual
drive in ETERNUS CS HE. The drive coordinates are stated in the form:
ACS(0-126)-LSM(0-23)-Panel(0-19)-Drive(0-19).
The numbers in brackets state the permitted values where only the values 0-11 can be
used for NetBackup in drives. This must be followed in the definition of virtual drives in
ETERNUS CS HE.
●
When using the DAS Robot interface, you must ensure that in NetBackup V3.4 only the
first 15 DAS drives are supported. As of NetBackup Version V4.5, up to 250 drives are
supported.
●
No additional modules are needed to support robot interfaces ACS and DAS. Windows
is an exception (see section “System specific” on page 238).
●
It is recommended that you do not configure the same device (virt. device in ETERNUS
CS HE) in several NetBackup systems. If the same device is under robot control in
parallel NetBackup servers, it can be disturbed by SCSI commands. Where necessary,
set the device to the NetBackup device status DOWN in the parallel system.
●
Before you can work with the DAS interface, you must authorize access to the drive via
DAS with: dasadmin alloc <virt. drive> UP <client>
DASADMIN is not shipped with NetBackup and must be purchased separately.
●
Details about the possible causes of connection problems with VDAS or VACS and
other troubleshooting advice is given in sections “Possible problems and solutions” on
page 401 (VDAS) or page 405 (VACS).
●
The ACS numbers configured in ETERNUS CS HE must be strictly ascending.
NetBackup(W2K3) would not be executable if, for example, ACS=0 is used for BS2000
and ACS=2 for NetBackup. Instead, use ACS=0 for BS2000 and ACS=1 for NetBackup.
●
A scratch pool must be configured in cmd_proc for NetBackup and the virutal volumes
must be accommodated there:
> define pool 0 5000 1
# define poolid 1 for max. 5000 volumes
einrichten
ACSSA> set scratch 1 NBU000-NBU999 # Add volumes to pool
ACSSA> logoff
●
The following filters must be entered in the configuration file
<netbackup_path>\volmgr\vm.conf:
INVENTORY_FILTER = ACS <netbackup_roboter_nummer> BY_ACS_POOL 1
<netbackup_roboter_nummer> is generally not equal to the ACSid configured in
ETERNUS CS HE.
220
●
The Virtual Tape Devices on the ETERNUS do not allow buffering higher than 256KB
Do not use tape buffers size more than 256KB (262144) in:
8.3.3.1

The drive types are inquired for each library (for each ICP). Here you must note
which ICP the displayed drives belong to.
NetBackup configuration is implemented as for Windows 2000. The administration
console is started with xvmadm. From here you go via the file menu to the Device
Management. Robots and drives are configured there.
The following processes must run on the LMF client (the programs vmps and bpps
belong to NetBackup):

8.3.3.2
Connection of the robot controller (VACS) via a firewall
From the current version of NetBackup on, connection of the ACSLS robot controller is
supported via a firewall.
NetBackup V5.0 and service release 3 (available on the Internet at:
http://support.symantec.com) were used under Solaris for quality assurance.
222
The robot name configured in NetBackup must be determined before configuration takes
place:
/opt/openv/volmgr/bin/tpconfig
-> 2) Robot Configuration
-> 4) List Configuration
Currently defined robotics are:
ACS(0) ACSLS server = 172.25.95.166
The following variables must then be set on the NetBackup server in the file
/opt/openv/volmgr/vm.conf.
Syntax: ( variable = robot name port)
ACS_TCP_RPCSERVICE
ACS_CSI_HOSTPORT = 172.25.95.166 2001
ACS_SSI_INET_PORT = 172.25.95.166 2001
In ETERNUS CS HE the fixed port is defined as follows:
GXCC -> Configuration -> VirtualLibraryService ->
VACS : RPC-Port Selection UserDefined
RPC-Port:
!
8.3.3.3
2001
Caution!
Communication is still handled via RPC!
Port 111/UDP may not be locked.
Template for supporting SCRATCH mount
When using an LV just for writing (FAST-MOUNT) NetBackup does not communicate this to
ETERNUS CS HE over the supported standard interfaces:
VDAS/DAS
VACS/ACSLS
aci_scratch_set
csc_set_scratch
Instead of this, the following template can be used on UNIX systems.
#!/bin/sh
#----------------------------------------------------------------------#
Example of fast access to (=recycle) volumes
#----------------------------------------------------------------------HOST=yin
VSNList=`/usr/openv/netbackup/bin/admincmd/bpmedialist -l | \
/usr/bin/awk '{print $11, $1}' | \
/usr/bin/egrep '^0' | \
/usr/bin/awk '{print $2}'`
for VSN in $VSNList
do
223
ssh $HOST vlmif conf -r -n -v $VSN
done
This script truncates the LV to the part which is always contained in the cache, so no restore
is required in the event of the next mount.
In newer versions of NetBackup the following template can be used:
set +vx
TZ=GMT-26
# set time + 24 h
HOST1=CS1
HOST2=CS2
DATE=`date +%m/%d/%Y`
# will be the next day in the script shell
TZ=Europe/Berlin
# Find tape (LV) which expire today in the media DBD's
/usr/openv/netbackup/bin/admincmd/bpmedialist -summary | /usr/bin/grep $DATE

By default a Windows machine does not have ACS Deamon (ACSD) build in the
Operating System. Because of that a Windows Host is unable to communicate with an
ACS Robotic through the LAN. ETERNUS CS HE just emulates an ACS Robot.

NetBackup configuration is implemented as for Windows 2000. The administration
console is started with xvmadm (another option is xnb). From here you go via the file
menu to the Device Management. Robots and drives are configured there.
As of Version 4.5 the Motif interfaces xbpadm, xbpmon, xvmadm and xdevadm are no
longer supported. The Java interfaces jnbSA and jbpSA are recommended, and also
the command line and the menu-based program bpadm.
●
The sg driver must also be installed. See: Media Manager Device Configuration Guide
Symantec NetBackup for UNIX, Linux, and Windows.
●To
avoid hold-ups due to long waiting times for messages, it is strongly recommended that
you lengthen the system message queue.
To do this, you must extend the file /etc/system with the following entry:
..
# Settings for Symantec NetBackup, T.Daude 28.02.02 Symantec Software GmbH
set msgsys:msginfo_msgmap=4096
set msgsys:msginfo_msgmax=4096

8.4.1 Documentation
The documentation for Data Protector is shipped on CD together with the product.
8.4.2 Licenses
The following licenses may also be needed for Data Protector:
–
–
–
Cell Manager Multi-Drive
Multi-Drive Server (if other servers are linked to ETERNUS CS HE)
Unlimited Slot Libraries Extension for STK ACSLS or EMASS/GRAU DAS
8.4.3 Miscellaneous
Up to Version 4.1 the software was marketed under the name Omniback.
As ETERNUS CS HE mounts virtual volumes extremely quickly, you must ensure that the
hardware configuration of the Data Protector environment is appropriately defined. To avoid
bottlenecks this may call for relocation of the mount server to its own system.
Data Protector currently only releases the media for a save job once the entire job has run.
As the media table is contained in shared memory, parallel long save runs can lead to a
bottleneck in media management. A remedy can be found in optimum distribution of the
long and short jobs. It is planned to change this behavior of the media management in
Data Protector V5.5.

Installation of Data Protector
●
Call /usr/sbin/swinstall
●
In the Specify Source window, choose the menu item Select Network Directory/CDROM and
specify the mount point of the CD-ROM. Then click OK to open the SD Install - Software
Selection window. The Data Protector product appears in the list of available products.
●
Select it for installation with Mark for Install under the Actions menu item.
●
Under the Actions menu item, select Install analysis and then click OK to start the installation.
●
After the installation you can start Data Protector with:
/sbin/init.d/omni start
and stop it with
/sbin/init.d/omni stop
●
Starting <DATA_PROTECTOR_HOME>/bin/xomni starts the graphical configuration
menu.
Configuration of ETERNUS CS HE in Data Protector
Note that the virtual drives register as FSC-CentricStor, so that Data Protector is unknown.
For this reason, when you click on the Data Exchange Device menu, you only get the error
message that no devices are present. In this case you must just specify the device nodes
manually e.g. /dev/rmt/c0t0d0BEST.
Up to version 3.5, you must also activate the menu item Use direct library access under
Advanced options in the drive configuration. From version 4.1 onwards, there is no need to
activate this item.
Under VDAS the option of using Exabyte Mammoth2 as a tape emulation is also available.
Here the media type T3480/T... is selected for FSC-CentricStor for library and drives, and
the media type Exabyte for Exabyte Mammoth2.
Under VACS it is not possible to use Exabyte Mammoth2 as the media type Exabyte
cannot be selected.

8.4.4.3
Data Protector
Template for SCRATCH mount support
When using an LV just for writing (FAST-MOUNT) Data Protector does not communicate
this to ETERNUS CS HE over the supported standard interfaces:
VDAS/DAS
VACS/ACSLS
aci_scratch_set
csc_set_scratch
Instead of this, on UNIX machines you can set the following template:
#!/bin/sh
#--------------------------------------------------------------------# Example of fast access to (=recycle) volumes
#
# Limiting conditions:
#
- Omniback must work with compressing device nodes
#
- Compression must be active in CentricStor
#--------------------------------------------------------------------VSNList=`/opt/omni/bin/omnimm -list_scratch_media "Default
T3480/T4890/T9490" | \
/usr/bin/grep "\[" | \
/usr/bin/awk -F[ '{print $2}' | \
/usr/bin/awk -F] '{print $1}'`
for VSN in $VSNList
do
ssh CentricStor-VLP conf -r -n -v $VSN
done
This script truncates the LV to the part which is always contained in the cache, so no restore
is required in the event of the next mount.
This script can lead to corrupted data because if between the creation list of media by DP
and the truncate of the volumes by CS, DP could write to one volume of the list and then
CS truncate the volume. When the list is created, the volumes should be freezed.
!
CAUTION!
When using the script it may happen that data is written to volumes and truncated
to the stub shortly after that, leading to corrupted data. Therefore only use this script
when a time interval without backups is guaranteed. If this is not possible, use the
script shift-lager-free.x to move volumes to the FREE pool temporarily (see
“Scripts for pool maintenance” on page 247).

8.4.4.5
Bypassing lengthy backup times in Data Protector
Under Data Protector the problem can occur that backup times are prolonged by a restore
on the back end. This is caused because sorting of the free (virtual) cartridges is a
permanent process, i.e. the FREE ALLOCATION TABLE is constantly being updated, with
the result that scratched and newly released cartridges get mixed. Load times range from
under one second up to several minutes.
This behavior for handling free (virtual) cartridges within Data Protector is bypassed by
removing the virtual volumes whose retention period is due to elapse on the next day from
the media pool and assigning them to a storage pool. The volumes can remain in the latter
pool until the retention period has elapsed. They are then scratched and moved into the free
pool from which Data Protector takes the tapes for backups.

VJUK configuration
Supported slots
Only 1500 slots are supported per VJUK emulation of DataProtector.
8.4.5.2
Autoconfiguration
An autoconfiguration menu is available for VJUK. With Devices ➟ Autoconfigure Devices... you
can call a self-explanatory autoconfiguration procedure.
8.4.5.3
Configuration of the robots under AIX
With DataProtector, AIX can only be used as a client.
8.4.5.4
Configuration of the robots under HP-UX
After the devices under /dev/rmt have been deleted, the insf -e command is executed.
This program creates all device files anew. The device for the robot can be found under
/dev/rac.
270
8.4.5.5
Data Protector
Configuration of the robots under Solaris
A prerequisite is that the following configuration files are correctly set up:
/kernel/drv/st.conf
/kernel/drv/lpfc.conf
The sst driver is required for the robot. This is supplied by HP and is located under
/opt/omni/spt. It is copied to /usr/kernel/drv using its configuration file sst.conf as
follows (take care!):
●
Solaris 32-bit:
$cp /opt/omni/spt/sst /usr/kernel/drv/sst
$cp /opt/omni/spt/sst.conf /usr/kernel/drv/sst.conf
●
Solaris 64-bit:
$cp /opt/omni/spt/sst.64bit /usr/kernel/drv/sparcv9/sst
$cp /opt/omni/spt/sst.conf /usr/kernel/drv/sst.conf
The robot’s target and Lun are copied into file sst.conf.
Subsequently the line below is entered in the /etc/devlink.tab file:
type=ddi_pseudo;name=sst;minor=character rsst\A1
i
Blanks may not be used for whitespace, but only TABs.
The driver is then installed:
add_drv sst
After the reconfiguration boot (reboot -- -r) you can search for the device file for the
robot under the /devices directory. A link to this must be created from the /dev directory
if the system has not done this automatically, for example:
ln -s /devices/pci@1f,4000/scsi@3,1/sst@4,1:character /dev/rsst4
You see the name of the rsst* device in the boot log (dmesg) or system log
(/var/adm/messages).
8.4.5.6
Configuration of the robot devices under Windows
After ETERNUS CS HE has been connected, the Windows system automatically recognizes the robot and the drives. You can see the robot under the autochanger in the device
manager. Tape and robot devices are displayed using the DataProtector devbra -dev
command.

IBM Tape Device Driver
In ETERNUS CS HE you are recommended to configure "IBM 3590E1A" or "LTO Ultrium
2" as the emulation for the Virtual Drives (VTDs).
With the exception of AIX, the appropriate IBM Tape Device Driver should be installed on
the UNIX and Windows platforms.
The IBM Tape Device Drivers can be downloaded from the following FTP site:
ftp://ftp.software.ibm.com/storage/devdrvr
All of the following commands are given on the administrative console.
Define the Library
DEFINE LIBRARY <name of library> LIBTYPE=ACSLS ACSID=1
Define a drive in TSM V4.x:
DEFINE DRIVE <name of library> <name of drive> DEVICE=<device file>
ACSDRVID=<ACS drive ID>
In Version 4.x a tape must be mounted in the drive in the drive definition.
In Version 5 and higher no tape needs to be mounted in the drive definition. The statements for defining a drive are as follows:
DEFINE DRIVE <name of library> <name of drive> ACSDRVID=<ACS drive ID>
DEFINE PATH <server name> <name of drive> SRCTYPE=SERVER DESTTYPE=DRIVE
LIBRARY=<name of library> DEVICE=<device file>
285

8.5.3 Installation and configuration with Gresham EDT
This software package makes it possible to control ACSLS controlled robots via Gresham
EDT with the External Library Manager Function. This function must be used in configuration
with HP-UX, as TSM does not support any ACSLS libraries in HP-UX.
For further information on the software see:
http://www.gresham-software.com
See product: EDT-DistribuTAPE™
289
Tivoli / TSM
8.5.3.1
Gresham installation
Version 6.2.1.0 was tested under HP-UX, and Version 8.0.0.0 under Solaris/SPARC.
The following package is played in:
edt.6210.hpux.tar.gz Gresham DistribuTape or
edt-acsls.8000.sol-sparc.tar.gz
EDT 6.2.1.0 under HP-UX:
The package was unpacked with gunzip and then extracted with
tar -xvf edt.6210.hpux.tar. Then the unpacked
OMIdtelm.6210.depot was installed with
swinstall -s /<full path>/OMIdtelm.6210.depot.
The software is installed by default in the directory: /opt/OMIdtelm
EDT 8.0.0.0 under Solaris:
The package was unpacked using gunzip and then extracted using
tar -xvf edt-acsls.8000.sol-sparc.tar. It was installed using the setup script.
The directory in which the software is installed by default is /opt/GESedt-acsls
8.5.3.2
Gresham configuration
Start the SSI agent
First the rc.edt script from the <installations path>/bin
directory must be edited; you can create it by copying from rc.edt.smp.
In this file the variable MEDIA_MNGR_HOST must also be changed.
You should enter the IP address or (with working name resolution) the machine name of the
VLP, on which the ACSLS emulation is running (see section “IP addresses and host names”
on page 396 and section “Virtual libraries” on page 397).
Then start the script with the parameter both. This starts the SSI process, and simultaneously initializes DistribuTape.
290
Tivoli / TSM
Set up a storage pool and add tapes on the VLP.
You log in to the VLP and start the program cmd_proc which can be used to configure the
emulation of the ACSLS connection.
You then create a pool using:
define pool <Low Water Mark> <High Water Mark> <Pool ID>
Watermarks and pool IDs:
Low Water Mark
Lowest number of available volumes which must be in the pool;
should be set to 0.
High Water Mark
Maximum number of available volumes in the pool; can be as
high as you wish, e.g. 10000.
Pool ID
A number given by you, from 0 to 65534.
All further commands can then be carried out again on the computer on which Gresham
DistribuTape was installed. However, it is also possible to continue working on the VLP with
cmd_proc.
You can now add volumes to the pool with the command set_scratch:
set_scratch -p <pool ID> -a <first volume> -b <last volume>
or
set scratch <PoolID> <first volume>-<last volume>
You can then see if everything is correctly configured using the query
q_pool -p <pool ID>.
Configuration of a library in Gresham DistribuTape
The complete configuration of a library is carried out using the configuration file elm.conf,
which is found under <installation path>/bin.
If it does not exist, you can copy the example file elm.conf.smp to elm.conf .

8.5.4 Configuring a SCSI library on AIX via VJUK
8.5.4.1
General
The VJUK emulation is supported as of version CS V3.0.
The term element number in the SCSI library corresponds to the term slot number in VJUK.
The device nodes in AIX must have the same slot or element numbers in the TIVOLI-SCSI
library as the virtual drives in the associated VJUK emulation of ETERNUS CS HE.
The VJUK administration tool vjukadmin can be used, among other things, to create an
inventory of the slots or drives, to unload volumes from the drives, and to transfer them
again to the slots.
Access to VJUK with vjukadmin is only possible in the offline status. vjukadmin permits
switching between offline and online. A host can only access the VJUK in online status.

3. Configuration of a non-shared library in the Tivoli Storage Manager V5.1.5
Example
define library aix-vj00 libtype=scsi
define path aix AIX-VJ00 srctype=server desttype=library device=/dev/lb0
define drive aix-vj00 rmt0 element=256
…
define path aix rmt0
device=/dev/rmt0.1
device=/dev/rmt1.1
device=/dev/rmt2.1
…
srctype=server desttype=drive library=aix-vj00
Special features for the Tivoli Storage Manager
Checking volumes with labels into a library:
label libvolume aix-vj00 search=yes volrange=X00000,X00999
labelsource=barcode checkin=scratch overwrite=yes
Checking a volume with an existing label into the library:
checkin libvolume aix-vj00 X00000 status=scratch checklabel=barcode
checkout libvolume aix-vj00 X00000 remove=no checklabel=no
300
Tivoli / TSM
The checkout is to take place with remove=no. If remove=yes the TSM would
attempt to transfer the volume into the VJUK’s I/O slot.
To harmonize the directories between the TSM administration and VJUK:
audit library aix-vj00 checklabel=barcode
or
audit library aix-vj00 checklabel=yes
If checklabel=yes each volume is mounted and the label read by TSM. With
ETERNUS CS HE this means that a volume which was migrated to a real tape must be
read into the cache again!
When checklabel=barcode the data inventory of VJUK and TSM is harmonized.
This operation lasts only a few minutes, even with 16,000 slots, for example.
audit library checklabel=barcode is recommended if TSM finds volumes
mounted in the last TSM run when it starts and cannot reset these, or if an audit library
is recommended by TSM.
If the TSM drives are not emptied by audit volume either, this must be performed using
vjukadmin unload and vjukadmin unmount.
!
8.5.4.3
CAUTION!
audit library with checklabel=yes causes problems with drives which still
contain volumes from the last TSM. TSM wants to load another volume in what
it regards as an empty drive and then aborts the audit function.
Modifying the VJUK configuration and notifying TSM
●
Modifying the VJUK’s robotics connection (TSM must be terminated to permit this):
The device node, e.g. /dev/lb0, must be removed in AIX and created again:
–
–
●
Remove with smit or with rmdev -l lb0 -d
Create again with smit
Modifying the number of slots:
It is sufficient to restart TSM.

Tivoli / TSM
Configuration of the Linux client
The default directory of the Linux client is /opt/tivoli/tsm/client/ba/bin.
1. The freely selectable name of the server is entered in the dsm.opt file:
servername tsm
2. The following entries are made in the dsm.sys file:
SErvername tsm
COMMMethod
TCPPort
TCPServeraddress
enablelanfree
LANFREECommmethod
LANFREETCPPort
TCPip
1502
<IP address/Name>
yes
TCPIP
1500
1502 is specified as TCPPort here. The default TCPPort is 1500. The value may
possibly have to be modified in the dsmserv.opt server file. The values are basically
freely selectable (1024 through 32767).
Configuration of the Linux Storage Agent
The default directory of the Storage Agent is /opt/tivoli/tsm/StorageAgent/bin.
First the configuration file of the Storage Agent, dsmsta.opt, is edited and the following
entry is made:
DEVCONFIG devconfig.txt
The Storage Agent writes device configuration data into the file specified here. This is
generated with the following command (in one line):
Ê
dsmsta setstorageserver myname=csagnt mypassword=xxxxx \
myhladdress=<IPAdresse des StAgent> \
servername=tsm serverpassword=yyyyy \
hladdress=<IPAdresse des TSM Servers> lladdress=1502
The TCP server address specified under hladdress must be the same as that specified in
the dsm.sys file (see above). This command also writes the following line into the
dsmsta.opt file:
SERVERNAME tsm
The Storage Agent can be started either in the background using the script
Ê
dsmsta.rc [ start | stop | restart | status ]
or in the foreground with the command
Ê
304
dsmsta
Tivoli / TSM
Configuration of the TSM server
First the following commands are issued on the server administration console dsmadmc:
Ê
set servername tsm
Ê
set serverpassword xxxxxx
Ê
set serverhladdress <IP address/Name of the TSM server>
Ê
set serverlladdress 1502
Ê
set crossdefine on
For each client for which data transfer via the SAN is envisaged the Storage Agent is
defined as if it were a server (one line!):
Ê
define server csagnt serverpassword=xxxxx hladdress=<IP addr./Name of
Storage Agent> lladdress=1500 [validateprotocol=all]
Here the name and password must be the same as those which were used in defining the
Storage Agent on the client. lladdress designates the LANfree data port.
Configuration of the SAN environment
i
In the documentation the configuration is described slightly differently.
The administration console can also be used to define the library, the drives, the device
class and the storage pool, e.g.:
Ê
define library centricstor libtype=acsls shared=yes
(or for VJUK: define library centricstor libtype=scsi shared=yes)
Ê
define path tsm centricstor srctype=server desttype=library device=/dev/lb0
Ê
define drive centricstor drive0 element=256
Ê
define path tsm drive0 srctype=server desttype=drive library=centricstor \

Ê
define path csagnt drive0 srctype=server desttype=drive \
library=centricstor device=/dev/IBMtape0
... further drives and paths ...
Ê
define devclass centrictape library=centricstor devtype=3590 format=drive \
estcapacity=900M mountretention=0 mountwait=1 mountlimit=drives
Ê
define stgpool centricpool centrictape maxscratch=100
Ê

Verification of LANfree data transfer
For this purpose the Storage Agent is started in the foreground as described above. The
administration console dsmadmc is used on the server. A backup is now made on the client.
On both consoles - Storage Agent and server - the data transfer can be observed by issuing
the following command several times:
Ê
query session
In this case the number of bytes received (Bytes Recvd) on the Storage Agent should be
incremented up to the full size of the backup, while on the server it should only be possible
to see the considerably smaller number of bytes for metadata.
If the backup is excuted with the command line program dsmc, e.g.:
Ê
dsmc archive /ein/directory/*
a summary of the backup is displayed on the console after it has been completed. Information on the LANfree data should be visible there, for example:
Total number of objects inspected:
374
Total number of objects archived:

Total number of objects updated:

General information
●
HP-UX + LINUX can only use ACSLS from TSM 5.3.2.0.
●
TSM uses the record length of 256 KB for all the platforms mentioned.
●
A drive is reserved alternately by the server and the agent in SCSI style for tape I/O.
Here it must be ensured that SHARED=YES and RESETDrives=YES are set.
●
8.5.5.6
If an agent crashes during reservation it is not always recovered automatically upon
booting. In ETERNUS CS HE the reservation of a drive for a host can be canceled by
stopping/starting the emulation.

The backup server on which ARCserve runs is connected to ETERNUS CS HE via FC. A
controller which has been released for the Primergy and the ETERNUS CS HE connection
and has the appropriate driver must be used for this purpose. When the Storport Miniport
Driver is used with any Emulex HBA the default settings are suitable, which means that
configuration is not required. Otherwise the controller and driver parameters must be set
appropriately for the connection of a tape library.
8.6.4 Startup and configuration of virtual libraries
8.6.4.1
Configuring a SCSI library (VJUK)
1. Configure the virtual library on ETERNUS CS HE and check the LUNs assigned with
the aid of GXCC.
The tape drives are assigned their LUNs automatically, starting with 0. The VJUK LUN
must be configured in the GXCC under Virtual Library Services, and it makes sense to
use the next free LUN after the tape drives. Windows and ARCserve have no problems
if there are gaps in the LUNs, however.
When a VJUK is configured in ETERNUS CS HE (GXCC ➟ Configuration ➟ Logical
Drives menu), the first LUN is automatically reserved for the controller and thus displayed as disabled. Any number of tape drives can then be assigned to this controller.
Their LUNs are assigned automatically.
When an Emulex controller is used the elxcfg or HBAnyware program can be employed
to configure the Emulex controller or to check whether the controller has recognized all
the ETERNUS CS HE LUNs.

CA ARCserve Backup
2. The operating system performs a device recognition. Under Windows this is done in the
Device Manager. No Windows drivers are required for the jukebox or tape drives;
ARCserve handles hardware control itself.
3. Start the ARCserve device configuration.
Here the tape drives are assigned to their jukebox.
It is advisable to use the Eject Media after Backup option in ARCserve (Device Configuration ➟ Library Properties or Global Job Options ➟ Operations). This ensures that an
Unmount/Eject is automatically performed at the end of a backup job, thus ejecting the
cartridge used from the virtual drive. Without this option ARCserve leaves the cartridge
in the drive in order to have it available more quickly for reuse.
4. Start the ARCserve manager.
5. Calling the Device Window.
The virtual jukebox with its drives and slots now appears here. After an initial inventory
the backup server is ready to operate.
8.6.4.2
Using an ACSLS library
The Sun Microsystems program LibAttach must ne used for library control for ACSLS
library support on Windows systems.
In addition, the ARCserve Enterprise option must be installed. Configuration is performed
by means of enterprise module configuration. The assignment of tape drives to libraries
and the assignment of tape volumes is performed using the coordinates predefined by
ETERNUS CS HE.
8.6.5 Import or export under ARCserve
With real hardware the Import or Export function under ARCserve is used to address the
mailslot of a jukebox in order to import or export cartridges without opening the jukebox and
thus forcing a complete, time-consuming inventory. This function is also supported in
ETERNUS CS HE; the Scalar 1000 contains 12 virtual Mailslots.
These mailsolts can be addressed from ARCserve, i.e. cartridges can be exported there
from the magazine and also be reimported into the magazine. However, since these virtual
mailslots with their virtual cartridges do not really exist, this function can only be used to
resort cartridges in the jukebox.

318
Time Navigator
After you have made these entries have the content of the library displayed and perform
reinitialization:
All the volumes (LVs) in the sepecified range are then accessible for the library.
TINA supports scatch pools. If an LV is recycled or migrated ETERNUS CS HE receives the
command to truncate the LV and to perform no further restore from the volume (PV).
For this purpose the line:
TRUNCATE_CARTRIDGE="yes"
must be inserted in the file:
%TINA_HOME%/Vtl/catalog_library/vtl_config.txt
!
CAUTION:
Atempo recommends that you should only use one drive when labeling as familiar
problems will otherwise occur.

VJUK emulation
8.8 VJUK emulation
●
Connection of the virtual robotics VJnn and of its virtual tape devices is implemented
via an FC switch.
●
Up to 48 virtual jukeboxes VJnn are supported per ETERNUS CS HE.
●
In the GXCC configuration virtual drives the vtd line on whose LUN VJnn is configured
is displayed but is not available for tape emulation (so-called shadow device with the
disabled identifier in the configuration file). You are therefore recommended if possible
to use a LUN for the robotics which is higher than the number of virtual drives (LUNs).
Note: The FC controller always permits LUNs up to 255. Sample tests with FSC
Networker on Solaris and VJNN on LUN 220 worked.
i
AIX needs the robotics on LUN 0.
●
Windows with VJUK recognizes more than 8 LUNS if a virtual drive and not the virtual
robotics is configured on LUN 0 in ETERNUS CS HE.
●
Maximum number of volume slots in VJUK:
Emulation
Maximum slots
OEM limit
FSC/CS-TL
61440
ADIC/Scalar-1000
61440
1182
ADIC/Scalar-10K
61440
22938
The slot limit of 61440 can be lower owing to the host platform/backup application.
320
●
The administration tool vjukadmin is supplied for VJUK. The slot sequence of the drives
and media which may need to be taken into consideration for configuring the backup
application is displayed using the inventory command.
●
On Windows 2003, after VJNN, the virtual drives in ETERNUS CS HE and zoning on
the FC switch have been configured, the LUNS/Tapes are reentered in the registry
without any further action, i.e. also without rebooting Windows 2003, and unknown
autochanger and the tape devices (EXABYTE driver for Mammoth2 V2.10 was already
present) are recognized and made operational.
●
No robotics driver must be installed specially for the FSC/CS-TL virtual jukebox in
Windows; the original Microsoft driver is activated automatically (unknown autochanger
from the manufacturer GenChanger with driver version 5.2.3790.0, driver date 21th of
June 2006 on Windows 2008).
VJUK emulation
●
VDAS and VACS can mount volumes from VJUK. A collision/operating errors can be
avoided by means of correct configuration or setting up the name ranges on the backup
server.
●
As in the real world, by default VJUK offers the backup application 1 transport unit for
mounting/unmounting logical volumes in virtual drives. In the event of a mount request
(SCSI move request) for restoring the relevant virtual volume from the real tape, VJUK
must consequently wait for the restore from the real tape to be completed and is blocked
for further mount/unmount requests during this period.
●
In the real world, library control via SCSI is not designed for long delays in the case of
SCSI requests. Consequently timeout values in the single-digit minute range are
customary in drivers and application programs. In the case of a mount request which
requests the virtual volume concerned to be restored from the real tape, SCSI aborts
can be caused by both the operating system and the backup application. In order to
prevent this, prefetch scripts should be used as far as possible so that virtual volumes
are read into a cache in advance.
Alternatively, in CS V4 and higher logical volumes can be configured on a TVC-resident
basis (LVG attribute Cache Policy with the value NO_BACKUP_TO_TAPE or
TVC_RESIDENCE) or a Disk Library Edition (models ETERNUS CS500DL and
ETERNUS CS1000DL) can be used.
321
NAS filer - NetApp
8.9 NAS filer - NetApp
Miscellaneous
The distinctive feature of the configuration is that the version of NDMP used (version 3)
does not support tape cloning.
ETERNUS CS HE offers an implicit cloning of tapes, so that now a copy of NDMP backups
can be made without extra burden on NetApp.
Requirements
–
–
NetApp F760 with operating system version ONTAP6.2R2 and FC controller
FC-BA X2045A (QLA2200).
NetApp connection via FC switch
Restrictions
Only the first 16 virtual drives of NetApp are recognized.
Configuration
●
ETERNUS CS HE ICP
Emulation IBM 3590E
Compression by HOST
●
NetWorker 6.1A10 with EKS 1-5 for Solaris
In /nsr/res/defaults make the following entry:
NSR_DEV_BLOCK_SIZE_3590=256
The NetWorker block size for 3590 must be adapted from default 384k to 256k. This is
because the DUMP command which is implicitly called on NetApp sets 256k as the
maximum block size.
The settings for the timer are as recommended for NetWorker (section “NetWorker
(EMC and Fujitsu)” on page 215).

DiskXtender for Windows
8.10 DiskXtender for Windows
DiskXtender for Windows is a software package from Legato (EMC) that saves data written
to a Windows drive which has been declared as an extended drive in a library on a changer
in accordance with specific rules.
Information on trademarks
●
DiskXtender for Windows, MediaStor and Legato are trademarks of the EMC Corporation.
●
SUN is a registered trademark of the Sun Microsystems, Inc.
●
EMULEX is a registered trademark of the EMULEX Corporation.
The expansion for DiskXtender for Windows in ETERNUS CS HE is available as of Release
3.1D SP01.
ETERNUS CS HE should first be configured and connected with the system on which
DiskXtender for Windows is running so that the ETERNUS CS HE tapes are already known
there when DiskXtender for Windows is installed.
To avoid complications, only the drives required for DiskXtender for Windows should be
generated, and only this ETERNUS CS HE system should be connected to the DiskXtender
for Windows system at fibre channel level (if necessary select zoning on the FC switch).
8.10.1.1
Virtual Library Services
ACSLS is used for communicating with DiskXtender for Windows, i.e. VACS on the
ETERNUS CS HE side. The following settings via GXCC ➟ Configuration ➟ Virtual Library
Services must be made to permit this:
Mode:
Enabled
RPC-Port Selection: Default
Access Control:
ON
323
A client entry must be generated for each extended drive on the DiskXtender for Windows
side:
Name:
UserId:
<Name of the DiskXtender for Windows system in capital letters>
By default the user ID has the following format:
DX_<Name of the DiskXtender for Windows system in upper case>_
<Extended Drive letter>
Volumes:
<All volumes which may be used for this extended drive>
The specified volumes are assigned to the extended drive of the DiskXtender system
specified in the relevant user ID.
Creation or deletion of a volume during ongoing operation - after VACS-reinit - is recognized on the fly on the DiskXtender for Windows side.
Example
DiskXtender system WILLI with extended drives D and E is assigned the logical
volumes DXD000 through DXD099 and DXE000 through DXE0999 respecively in

8.10.4 Further information
●
After labeling, DiskXtender for Windows displays the following sizes for the medium:
Total bytes: 19.999.948.800
Written bytes: 1.006.764.032
●
The Media Copy function is only possible within the ACSLS Media Services. It must be
ensured that the compression setting is uniform (see section “Logical Drives” on
page 324).
●
An alternative to Media Copy is provided by the Multi-Target Feature of DiskXtender for
Windows.
●
When any change is made to the ETERNUS CS HE configuration for any logical drive
(vtd on ICP), all tape device emulations are stopped and restarted in ETERNUS CS HE
V3.1D throughout the ICPs when Distribute and Activate takes place. When Distribute and
Activate takes place in ETERNUS CS HE with the tape device emulations being
stopped/started, the ACSLS Service and the volumes in DiskXtender for Windows go
offline. Remedy: Reboot the DiskXtender for Windows server.
But such uncontrolled offline statuses for DiskXtender for Windows should be avoided
so as to prevent potential inconsistencies in the DiskXtender for Windows environment.
Consequently configuration/reconfiguration of logical drives in ETERNUS CS HE
should only be performed on the ICP on which the tape device emulations for DiskXtender for Windows run during previously announced maintenance times or be
activated with Distribute and Activate. For the purpose of this maintenance, the DiskXtender for Windows server should first be shut down and rebooted following a
successful Distribute and Activate.

8.11.2 ACSLS library in Simpana with VACS
In the library configuration for CommVault Simpana the Work Pool Number 0 and the Volume
Range NoScratch have to be specified. This leads CommVault Simpana to scratch a released
volume before reusing it. Different to a manual Erase/Scratch in CommVault Simpana migrated logical volumes are not recalled from physical drives when an automatic Scratch Mount

●
The service Removable Storage (RSM Removable Storage Management) must be stopped and disabled in Windows (Administrative Tools).
●
The original driver from Microsoft (see section “VJUK emulation” on page 320; 8th item)
is enabled automatically in Windows for the virtual robotics VJUK in ETERNUS CS HE
In the device manager is the Library as „Unbekannter Medienwechsler/Unknown Medium Changer” displayed.
Configuring the SCSI library and tape drives
343
The Select Drives list shows the virtual tape drives which are physically recognized in Windows. The checkmark may not be used as a selection character for those tape drives which
are not under corresponding VJUK control in ETERNUS CS HE or which are not to be employed with VJUK in the Simpana application (in the example only the 16 tape drives from
LUN 0 through LUN 15 are relevant for VJUK and are to be configured in Simpana).
344
When automatic detection takes place by means of Exhaustive Detection of the SCSI library
and of the tape drives, at least one virtual volume from the volume range of the associated
VJUK must exist in ETERNUS CS HE beforehand as Exhaustive Detection mounts/unmounts
a volume on each device:
In the example precisely one volume is mounted/unmounted on all 16 selected tape drives
(see above) one after the other via VJUK in the case of Exhaustive Detection. In this case no
data is written (in contrast to Validate drive for configured tape drives (see section “Further

8.11.4 ADIC DAS Library in Simpana with VDAS
i
The configuration of an ADIC DAS library in CommVault Simpana with VDAS requires
at least ETERNUS CS HE V5.0A SP01!
Configuring the ADIC DAS library
Prior to configuring, make sure that the "NobleNet Portmapper for TCP", installed with the
QUANTUM DAS-Client(ACI) software, is started:
i
Potential services for ACSLS/VACS (StorageTek LibAttach, SUN RPC Portmapper)
are from experience incompatibel with the NobleNet Portmapper and therfore must
be deactivated.
The following configuration steps are illustrated using the example of an ADIC DAS Library
in Simpana 8.0 SP05 on Windows 2003 (in the example mch003sx) with ETERNUS CS HE
(in the example VDAS on VLP eule).
351

Ê
358
Opening dialog window Drive Properties and entering its VDAS-LibDev name (as
specified in ETERNUS CS HE) in the Drive ID field for each tape drive:
i
The ETERNUS CS HE VDAS-LibDev names that are automatically
detected by Simpana are offered in the Drive ID list.
Compare these with the "serial number" as shown in ETERNUS CS HE
(XTCC on ICP, vtls.conf).
!
In the Drive ID field the LibDev name must be entered that exacty
corresponds to the LUN or the device node.
Ê
Configuring each tape drive:
359
Ê
After completely configuring the library and its drives in Simpana, it is useful to verify
them by means of Simpana with the so called "drive validation". In doing so, media must
be available in the ADIC DAS library in Simpana, in order to tentatively perform a
Write/Read.
i
360
In ETERNUS CS HE it can be configued via "Virtual Library Services VDAS"
which media, i.e. logical volumes of the ETERNUS CS HE, are detected by
Simpana in its ADIC DAS library or can be accessed.
8.11.5 Further information
●
It is recommendable to check the configuration of the tape drives by means of Simpana
drive validation (Validate drive context menu writes and reads) before performing a backup.
●
Number of data transfer operations for a media agent:
When messages containing Total number of data transfer operations on the
MediaAgent exceeds the maximum allowed value appear, it may be necessary to increase
the parameter Maximum number of parallel data transfer operations in MediaAgent Properties
➟ Tab General.
The default value is generally 25 (see CommVault Simpana 7.0 Manual Features - Media Management, page 338 and 342).
361
i
●
When checking the configuration, ensure that the maximum number of parallel
data transfer operations (see above) is limited to the default value of 25 in the
case of jobs for drive validation.
If a very large number of logical volumes results in the CommCell Console GUI slowing
down or hanging - e.g. when the slots are displayed - the size of the Java memory for
the GUI call of the CommCell Console can be increased. For this purpose the -Xms512m
and -Xmx1024m parameters are added below the icon CommCell Console GUI ➟

VTCP
8.12 VTCP
VTCP (Virtual Tape Control Program) is a backup application which runs on Fujitsu
mainframe servers. It was developed specially for using an ETERNUS-VT600 system,
which is equivalent to CS V3.1.
A Fujitsu document describes how the service engineer must adjust ETERNUS VT600 (CS
V3.1D) after it has been installed in a Fujitsu mainframe environment to permit it to work
with VTCP.
8.12.1 Incompatibility problem in ETERNUS CS HE V4.0A and higher
The introduction of the FHS (Filesystem Hierarchy Standard) and the standard security features in CS V4.0A and higher not only removed the basis for the configuration adjustments
described in the document mentioned above, but also required changes to the VTCP software.
To solve this problem, in CS V4.0A and higher the vtcp-config tool was provided which permits exceptions to FHS compliance (reintroduction of the /usr/apc/... paths) and cancels some of the security features (enabling of rexec and setting up a vtcp user account
which has no password). Use of the tool as described in the section below enables the current VTCP software to work directly with ETERNUS CS HE.
8.12.2 Use of the vtcp-config tool
The two operations in the original Fujitsu document
adduser vtcp
passwd vtcp ...
must be replaced by
/opt/fsc/CentricStor/etc/vtcp-config -configure
This implements the required measures on both VLPs. In addition, it must be ensured that
IP reverse lookup on the VLPs of ETERNUS CS HE functions for the host systems which intend to use this interface.
The following command can be used to delete the vtcp user account and to disable rexec on
both VLPs:
/opt/fsc/CentricStor/etc/vtcp-config -deconfigure
368
VTCP
The current status of the VTCP configuration on the ISP concerned can be queried with the
command
/opt/fsc/CentricStor/etc/vtcp-config -status
The following files and directories are affected when the tool is used:
/etc/xinetd.d/rexec
/etc/hosts.allow
/etc/passwd
/etc/shadow
/home/vtcp

ACSLS coordinates and LibDevName
In ETERNUS CS HE logical volumes are based for ACSLS in a home-location. To identify
the home-location of your LVs log on to CLI and start cmd_proc. Enter query volume all
or for a specific volume query volume AK0000.
Example output
ACSSA> query volume AK0000

At first you need to identify the first two numbers (acs and lsm). Afterwards you can
configure your Logical Drives with the same ACS and LSM. It is important to configure the
right LibDevName. Otherwise NVBU will not be able to handle drives and media.
i
If there are ACS and LSM differently configured in ETERNUS CS HE, the homelocation of LVs will be set automatically to 1,1,1,1,1.
For additional information see also „LibDevName in the Service Manual“ (GXCC
Main Menu ➟ Configuration ➟ Logical Drives ➟ LibDevName).
The name comprises four decimal digits, the so-called coordinates, separated by ','.
The following rules apply here:
1. coordinate (ACS): 0 - 255, 1 is recommended as the default
2. coordinate (LSM): 0 - 23
3. coordinate (PANEL): 1 - 10, 12 -15
4. coordinate (DRIVE): 0 – 19
i
This means NVBU supports a maximum of 280 drives with VACS (14 panels * 20
drives).

NVBU Configuration
In NVBU Configurator (Start ➟ BakBone Software ➟ NetVault Backup ➟ NVBU Configurator)
select “Media Manager” Tab.
Enable „Use barcodes as labels“.
Set “Unavailable device retry interval (mins)” to 1. This reduces the drive’s offline time.
Media request timeout
Here you can define how long NVBU has to wait for media. It is defined by each backup job
but can be saved in a policy. This is a possibility to avoid timeouts while restoring migrated
LVs which want to be reused.

9 ETERNUS CS HE NAS functionality
9.1 Network connection of the ETERNUS CS HE NAS frontend
9.1.1 Use of IP pools
ICPs of an ETERNUS CS HE cluster on which the NAS services NFS and/or CIFS are configured are also referred to as NAS ICPs.
Clients which use the NAS services of an ETERNUS CS HE must have an IP connection
to at least one NAS ICP in order to be able to mount the NAS filesystems or file groups exported from ETERNUS CS HE.
To achieve load distribution and high availability of the data paths between NAS clients and
NAS ICPs, the IP addresses of the NAS ICPs which can be reached from NAS clients must
be configured in IP pools. Each IP pool contains a group of IP addresses and assigned network interfaces. ETERNUS CS HE guarantees the availability of all IP addresses of an IP
pool for NAS clients as long as at least one network interface which is assigned to the pool
is operable.
Interfaces of the type ACCESS can also be configured on a NAS ICP. However, these interfaces are not used for connecting NAS clients and are not described below.
The following rules apply for creating IP pools:
●
An IP pool must contain at least one IP address.
●
An IP pool may only contain IP addresses in the same IP subnetwork.
●
If an IP pool contains fewer IP addresses than network interfaces which are assigned
to it, interfaces can remain unused.
●
If an IP pool contains more IP addresses than network interfaces which are assigned to
it, there will be interfaces to which more than one IP address is assigned.
●
A network interface can be assigned to only one IP pool.
●
Different IP pools must contain addresses in different IP subnetworks.
385
ETERNUS CS HE NAS functionality
When multiple IP pools are used, a corresponding number of subnetworks must exist in the
customer network. It is, however, not necessary to define more than one IP pool just to be
able to use all the network interfaces which are available on the NAS ICPs. The rules for
configuring IP pools enable multiple network interfaces of a NAS ICP to be assigned to the
same IP pool and consequently to the same IP subnetwork.
9.1.1.1
Load distribution in IP pools
The data traffic on the incoming side is distributed over the available interfaces of a NAS
ICP by the NAS clients making equal use of the IP addresses of the IP pools with their assigned interfaces. Routing settings on the NAS ICP are responsible for the distribution of
the outgoing data to the interfaces of a NAS ICP. When effective load distribution is achieved on the incoming side, this is also the case on the outgoing side.

ICP2
The figure shows a configuration comprising four NAS clients, each of which uses a particular IP address to communicate with a total of two NAS ICPs of the ETERNUS CS HE.
Two addresses of an IP pool are configured on each NAS ICP. The NAS ICPs transfer packets to clients via the same interfaces that were used to receive the clients’ jobs.
9.1.1.2
High availability of the data inputs
When a network interface fails, ETERNUS CS HE initially attempts (if possible and if so configured) to switch the IP address of the failed interface to an alternative local interface on
the node (local failover) which belongs to the same IP pool as the failed interface. In this
case the active data stream is retained.
386
If no such interface exists, ETERNUS CS HE switches the IP address to an interface of the
same IP pool on another node (global failover). In this case the active data stream is interrupted.
In both cases it is ensured that the IP addresses assigned to the services are always available.
9.1.1.3
Load balancing via DNS server configuration
This section describes how DNS load balancing can be used to enable a Network Attached
Storage which is implemented in the network by multiple servers to look like a service with
a single point of access.
Method of operation
DNS permits multiple IP addresses to be assigned to one name. If such a name is queried
by a resolver, the DNS server always returns all known IP addresses, but in a changing order. The resolver then has the responsibility of deciding which IP address is actually used.
The strategy according to which a DNS server specifies the order can be configured in the
case of bind-compatible name servers. Three variants are possible in the case of BIND: cyclical, random and permanent. With the permanent variant the IP addresses are returned
in the order in which they are contained on the name server.
The DNS query by the client is only issued the first time a connection is set up. If the client
knows the IP address, it always communicates with the server of this IP address when
further queries are issued. Access to another server is excluded. The problem of session
binding, in other words when a particular client always has to communicate with the same
server, as is the case for CIFS and NFS, does not occur with DNS.
Configuring ETERNUS CS HE NAS with DNS load balancing
ETERNUS CS HE NAS with DNS load balancing requires a DNS server in the environment.
The IP address of each NAS data input must be entered in this with the same name.
387
client1
.....
clientN
DNS
LAN
ICP1

VLP
ETERNUS CS HE
The procedure for doing this is presented taking a DNS on Microsoft Windows Server 2003
as an example:
1. Start -> Administrative Tools -> DNS
2. In the console tree, right-click the applicable forward lookup zone and click New Host.
3. In the Name text box, type the DNS computer name for the new host.
4. In the IP address text box, type the IP address for the new host.
5. Select the Create associated pointer (PTR) record check box to create an additional
pointer record in a reverse zone for this host, based on the information you entered in
Name and IP address.
6. Click Add Host to add the new host record to the zone.
i
388
To avoid the need to enter the NAS clients in the ICP’s host file, it makes sense to
configure the DNS server for the ISPs as well. This can also be done from the VLP.
9.1.1.4
Restrictions for clients which are reached only via routers
All IP packets to systems outside the subnetworks to which a NAS ICP has direct access
are sent to the default router.
i
If the default router is part of the subnetwork of an IP pool, appropriate routing settings on the NAS ICP guarantee that the corresponding IP addresses (with the assigned interfaces on the NAS-ICP) including NAS clients, which are outside the
subnetworks to which a NAS ICP has direct access, can be used as target addresses without restriction.
!
CAUTION!
Currently only one default router can be configured per NAS-ICP.
9.1.2 Detailed settings for network interfaces
ETERNUS CS HE V5 enables connection parameters of the Link Layer of a network interface to be set explicitly. By default these settings are specified between the network interface and the switch by means of autonegotiation. In certain cases, however, it can be necessary to set the parameters manually, e.g. when autonegotiation is not possible or fails.
In the configuration window Network Interfaces the autonegotiation specification must then
be set to NO for the interface concerned. Furthermore, the connection speed and duplex
mode must be specified explicitly.
i
These setting options exist for all network interfaces, not just for those in an IP pool.
9.1.3 Releasing filesystems and file groups
NAS filesystems or NAS file groups are released on the NAS ICPs. If a NAS filesystem in
the ETERNUS CS HE configuration has not been assigned to an HSM service, it is released
completely. If, on the other hand, it is managed by an HSM service, separate releases are
performed for all file groups of the filesystem.
ETERNUS CS HE generates the release with permanently predefined attributes.
389
9.1.3.1
NFS releases
NFS releases are listed in the /etc/exports file on every NAS ICP. ETERNUS CS HE generates entries there with the following attributes:
<fsname>
*(rw,fsid=<id>,secure,no_subtree_check,sync,root_squash)
<fsname> is the name of the filesystem or file group. This name may not be changed. Nor
may the administrator add or remove releases.
<id> stands for a particular numeric filesystem ID determined by ETERNUS CS HE. Each
entry in /etc/exports contains its own <id> which the administrator may not change.
The remaining release attributes, on the other hand, may be changed. Following this action
the NFSD component must be stopped and then restarted on all NAS ICPs. The XTCC interfaces must be used to stop and start the NFSD component.
The release of the filesystem or file group is not restricted to particular users or client hosts
and should be adapted to the requirements of the customer network.
The other entries have the following meaning:
rw
The filesystem or file group is exported for the purpose of reading and writing. It
makes no sense to change this attribute, assuming that the filesystem/file group is
used as a storage location for backup and archive applications.
secure
The NFS server checks whether all client jobs are sent from privileged ports.
For security reasons you are recommended not to change this attribute.
no_subtree_check
The NFS server does not perform the check to see whether a client’s job concerns
a file which resides in an exported subtree of the filesystem. Provided applications
do not configure any hard links between filesystems of different file groups of the
same filesystem, the setting should not be changed.
sync
The NFS server executes all write jobs of NFS V2 and all commit jobs of NFS V3
synchronously, i.e. the client receives an acknowledgment only when the data has
been persistently stored on the server. The opposite setting async does achieve
higher performance of the NFS server. However, in this case the client receives an
acknowledgment for the storage of data which is not yet persistent on the server and
would be lost if the server were to crash. Whether such situations are tolerable depends on the client’s restart behavior. You are recommended to retain the sync setting.
390
no_root_squash
When the client issues a job with the privileged user ID 0, the server also executes
the job with this ID. For security reasons it may be necessary to change this setting
on root_squash. The server will then map all client accesses with user ID 0 to accesses with a nonprivileged user ID (by default the ID of the user nobody). In this
case the administrator must ensure that the applications on the NFS clients also
have access rights with nonprivileged user IDs to all the required data of exported
NFS filesystems and file groups.
9.1.3.2
CIFS releases
CIFS releases are managed in a database which is synchronized throughout the cluster.
They can be displayed using the net conf list command.
Contents of the [global] section may not be changed.
Only settings of sections which describe the releases of the various CIFS shares may be
changed (but releases may not be added or removed). As with the NFS releases you are
recommended to supplement the attributes by access lists for authorized users and/or
hosts.
CIFS shares are released by ETERNUS CS HE with the following attributes:
path = <fs_fg_path>
Path of the released filesystem or file group. This setting may not be changed.
comment = <text>
Comment text (may be changed)
read only = no
The filesystem or file group is released for reading and writing. It makes no sense
to change this attribute, assuming that the filesystem/file group is used as a storage
location for backup and archive applications.
391
9.1.4 User configuration
The users and groups whose identities are used by the NAS clients to access the released
filesystems and file groups must be configured on the NAS ICPs.
The user IDs/group IDs must be generated on all NAS ICPs, and the user IDs/group IDs
must be the same on each node.
With NFS, numeric user IDs and group IDs are used to validate the client’s accesses. These
IDs are transferred 1:1 between the client and the server. If the client uses an ID which is
not known on the server, the server maps this ID to an "anonymous", nonprivileged ID. It
does the same when access takes place with the super user ID 0, different to the default
NFS release generated by CS (see attribute “no_root_squash” on page 391).
With CIFS, the client logs in as soon as a CIFS share has been mounted. In this case an
ID must be used which is known on the server. This ID must exist on all NAS ICPs as a
Linux ID, and it must be known to the Samba server on a NAS ICP which is used as a CIFS
server before the first login of a NAS client can take place. This is done using the following
command:
smbpasswd -a <username>
When a CIFS client logs in, the user name and password are queried.
9.1.5 Protection period
In released NAS filesystems with the attribute PROTECTABLE=Yes, applications can establish a protection period by setting the file access stamp to a future point in time. However,
file protection becomes effective only when no write permission is set for the file.
i
A protected file cannot be changed or deleted before the protection period has
elapsed.
File protection can be removed before the protection period has elapsed, but only by calling
the administration command ecs-del-protection on an ETERNUS CS HE node.
392
Separating physical devices of the VTL and of the NAS
9.2 Separating physical devices of the VTL and of the NAS
backend by FC zoning
In ETERNUS CS HE systems which are used simultaneously as virtual tape libraries and
as NAS/HSM servers, the same SCSI tape drives and SCSI libraries may not be visible simultaneously for VTL IDPs and for NAS IDPs.
This assignment of the devices to FC zones and appropriate configuration of the FC switches ensure that the devices provided for VTL or NAS purposes can be accessed only by
the relevant IDP nodes.
9.3 Joint use of logical devices and libraries by the VTL and the
NAS backend
It is possible to use the logical drives and virtual libraries provided by the ETERNUS CS HE
as backend devices for the NAS/HSM services. This can be done by either cascading two
separate ETERNUS CS HE systems or by creating a 'loopback' configuration in which the
FC-ports of the NASIDP are directly cabled to FC-ports on one or more ICPs. A connection
for the library access must also be provided (either FC or LAN). The following points must
be considered when building up such a configuration.
●
The VTL resources that are to be used by the NASIDP must be completely configured
and activated before they can be configured for use in the NASIDP.
●
The library access can be implemented via FC (vjuk) or via LAN (vacs).
– The FC connection is restricted to no more than 64K LVs per vjuk however multiple
vjuk libraries can be configured.
– The LAN connection between NASIDP and the VLP must be provided externally to
the ETERNUS CS HE to enable the Auto VLP failover function.
●
The selection of the size of the LVs used has a very large effect on the access times of
files that have been migrated and must be retrieved from tape. As does the number of
LDs
●
The FC connections from the NASIDP to the ICPs should be distributed to different ICP
to ensure availability of the LDs if an ICP fails or is taken out of service.
●
The two data replication options must be considered, either TVPG with primary and
copy TVPs or the more flexible dual/triple save LVGs. The data replication factor and
data transfer requirement during the entire process being the decisive factor.
●
The additional load on the VTL cache / ICP and IDP's must be considered.

Useful commands and information
10.3 ETERNUS CS HE configuration data displays for the user
To set up the host configuration, you often need information on which ISP a device
emulation, a library emulation, a device server (PDS) or a library server (PLS) is running.
You receive a compact overview in global status, to start e.g. with:
GXCC main window ➟ Function bar ➟ Tools ➟ Global Status.
10.3.1 IP addresses and host names
ISP
The IP addresses of the ISP are shown at the top of the XTCC main window. The host name
is visible in the label of the ISP icon in the GXCC main window.
The IP addresses of the ISP are also contained in the list which can be viewed with:
GXCC main window ➟ Function bar ➟ Administration ➟ Show WWNN and WWPN
Libraries
The IP addresses of real libraries are shown in the GXCC main window in the robot icons
at the bottom of the display and in the related balloon help.
FC switch
The IP addresses or host names of the internal FC switch (or switches) are displayed in the
object information of the FC fabric.
10.3.2 Emulations
The emulations are represented as columns over the host name of their ICP in global
status. If you leave the mouse pointer over the box which represents the emulation or virtual
device, this will display the name of the emulation, the LUN (fibre channel) or the device
name (ESCON) and the number of the assigned controller and the robot address.
In the XTCC of the relevant ICP you can obtain the same information by left clicking the icon
of the emulation or the virtual device. The inquiry data which have been set are displayed
in the icon of the virtual device.
There is a printable overview at
Global Status ➟ Function bar ➟ Tools ➟ Show Balloon Help Summary.
396
10.3.3 Virtual libraries
The libraries are represented in Global Status by boxes next to the emulations. If you leave
the mouse pointer over the icon, the ISP and emulation type will be displayed.
For VDAS and VACS types, the entered clients are outputted in the balloon info of the icon
in the XTCC window.
The Balloon Help Summary also shows on which ISP the relevant emulation is running.
10.3.4 Real devices (PDS)

Control of ADIC / ABBA / AML libraries
10.4 Control of ADIC / ABBA / AML libraries
10.4.1 DASADMIN
In the host
●
The host is the DAS client of VDAS in ETERNUS CS HE.
The following variables must be set and exported:
DAS_SERVER=<name or IP address of the VDAS servers (see page 397)>
e.g. DAS_SERVER=172.25.95.172
DAS_CLIENT=<name of client (=own name) in configuration>
e.g. DAS_CLIENT=suse7
In ETERNUS CS HE
●
ETERNUS CS HE (VLS) is the DAS server for the hosts.
The host should be added to the list of VDAS clients. Its access rights must be set. The
process is described in the maintenance manual under Configurations ➟ Virtual Library
Services.
●
ETERNUS CS HE (PLS) is the DAS client for DAS in AMU-PC.
In this context, DASADMIN can also be started on the PLS host of the ETERNUS CS
HE (in the general VLP).
The IP address of the AMU-PC is entered under Configurations ➟ Physical Library
Services.
Drives (PDS) and library services are brought together as libraries with Configurations
➟ Tape Libraries. Here you must also specify if ETERNUS CS HE takes over the
cleaning management for the drives.
398
In the Aan ETERMU PC
ETERNUS CS HE (PLS) is the DAS client of the DAS server in the AMU.
●
In the DAS server, the service engineer must configure the VLP on which the PLS (or
PLSs) run, as the ACI client for the physical ETERNUS CS HE drives.
After activating the configuration, there should be a function check of mount and
dismount via dasadmin. For real devices this is done from ETERNUS CS HE (host of the
relevant PLS), for virtual devices it is done from the hosts.
i
If you wish to perform the physical cleaning of the tape drives for some or all drives
via ETERNUS CS HE (see section on Configuration ➟ Tape Libraries in the maintenance manual), then the automatic cleaning for these drives must be deactivated
on the AMU-PC. If CLN volume groups are also shown in Global Status next to the
physical volume groups in the library, ETERNUS CS HE administers the cleaning
of the drives in the corresponding library.
In vtls.conf, the IP address of the server for the physical library is defined in the section
[pls]. The client is defined in the variable SYSNAME (also see page 397).

10.4.2 Communication between client and server
It is common practice these days to construct firewalls between individual security cells.
Here, we describe how communication works in these cases.
RPC communication for DAS control:
DAS client
DAS server
Enquiry for port of program number: 536875008 via
TCP/UDP Port 111
(in UNIX: rpcinfo –p <DAS server>)
Returns port <XXX>
The port is either located dynamically in the system
after server start or can be assigned in VDAS.
A request is made to the DAS server:
The client finds itself a free port and registers itself with
rpcbind with Port <YYY> and a program number. This
is a number from 40000000 and is increased with
every request. A free port is requested every time.
The rpc function communicates the client program
number, where the response is awaited.
Request to DAS server via TCP/IP Port <XXX>
Enquiry for port of program number which was given
via TCP/UDP Port 111
Returns port <YYY>
Confirmation message for the request via port <YYY>
The client logs out of rpcbind releases the port <YYY>
again.
400
10.4.3 Possible problems and solutions
Problem: No connection to VDAS from the SAN host is possible via dasadmin.
●
Call dasadmin qversion on the VLP. For this call, the host (VLP) must be defined in
vtls.conf.
●
Check with rcpinfo -p on the VLP, to see if the rpcbind process works.
●
Is the UDP protocol (see communication between client and server) blocked by a
firewall?
●
In Windows 2000 the variables DAS_SERVER and DAS_CLIENT must be defined as
system variables under: Start ➟ Settings ➟ Control Panel. In Control Panel, select the
entry System (System Properties). In System Properties, click the Advanced tab. In the
center you will find a button called Environment Variables.
●
With the variable ACI_DEBUG=1, a further trace stage can be set.
401
Control of the StorageTek libraries
10.5 Control of the StorageTek libraries
This describes how the physical libraries are operated.
10.5.1 Cleaning management in StorageTek libraries
If the automatic cleaning for the drives (with STK this applies either for all drives or for none)
is to be switched off and ETERNUS CS HE has to take over the cleaning, proceed as
follows:
1. Call acsss_config on the ACSLS computer and select the following menu item:
3: Set general product behavior variables
2. From the parameters which are then offered, set Enable Transport Auto Clean Option to
FALSE.
Make sure that cleaning management is activated in the ETERNUS CS HE configuration.
If CLN volume groups are also shown in Global Status next to the physical volume groups
in the library, ETERNUS CS HE will administer the cleaning of the drives in the corresponding library.
10.5.2 Adding tapes in L180
●
Open the door, and sort the tapes into the slots.
●
Then close the door again. The robot then makes an inventory run of all the tapes found
in the library.
10.5.3 Partitioning a library
The SL500, SL3000 and SL8500 robots can be split into a number of partitions. The relevant chargeable license from SUN must be read in to do this. Robot control must take place
by means of an FC switch and the corresponding zoning. The partitions are configured
using the control program SL-Console with the firmware status FRS_4.40 or higher.
i
402
A firmware status of 1300 or higher is required for SL500.
10.5.4 Starting the ssi daemon
The ssi daemon needs 3 environment variables:
–
–
–
CSI_HOSTNAME=<name of the SUN controller computer with the real robot or of the
VACS host>
CSI_CLIENTNAME=<name of client computer>
CSI_TCP_RPCSERVICE=TRUE
The ssi daemon is started with the command: ssi 0 50004 23
10.5.5 Stopping the ssi daemon
1. Request the PID with ps –ef | grep ssi.
2. kill –15 <pid>
10.5.6 cmd_proc
In order to be able to use the program, the ssi process must be running.
Operations with cmd_proc:
Inform
query drive all
Mount
mount <VOL> <POS>
e.g. mount TDS004 2,0,0,1
Unload
dismount <VOL> <POS> f
e.g. dismount TDS004 2,0,0,1 f
Show scratch pools
query pool all
Show contents of a scratch pool

logoff
10.5.7 Communication between client and server
It is common practice these days to construct firewalls between individual security cells.
Here, we describe how communication works in these cases.
403
RPC communication for ACSLS control
ACSLS client-server communication:
ACSLS
server
Request via Port
50004 →
(50000–50099
possible)
Enquiry for port of program number: 300031
via TCP/UDP Port 111
← Response via
dynamic port
← Returns port <XXX>
(in UNIX: rpcinfo –p <ACSLS server>)
The port is either located dynamically in the
system after server start, or it can be
assigned in VACS.
A request is made to the ACSLS server:
SSI daemon
Robot controller program
ACSLS client
If the SSI daemon has still not registered
with rpcbind, it finds a free port and registers
with rpcbind with port <YYY> and the
program number. This lies between
1234567886 – 1234567985 and depends
on the port number of the client.
e.g. Port 50004 == 1234567890
The rpc function communicates the SSI
program number, where the response is
awaited.
Request to ACSLS server via TCP/IP Port
<XXX> →
←Enquiry for port of program number,
which was given, via TCP/UDP Port 111
Returns port <YYY> →
← Confirmation message for the request via
port <YYY>
The SSI daemon does not log out from
rpcbind.
404
Information on the Cashion connection
10.5.8 Possible problems and troubleshooting advice
Problem: No connection to VACS possible from SAN host.
●
Call cmd_proc -p 50099 on the VLP.
●
On the VLP use rcpinfo -p to check whether the rpcbind process works.
●
Is the UDP protocol (see section “Communication between client and server” on
page 403) blocked by a firewall ?
●
Under Windows 2000 and WIN-NT the Storagetek Libattach and PowerRPC Portmapper
services must be active.
10.6 Information on the Cashion connection
For a Cashion connection over 122 m, 2 COM servers (COM <-> Ethernet) from
W&T1 - Product 586312 - were used which were configured in box-to-box mode.
The configuration is described in the manual3.
The following parameters from the standard package had to be modified here:
●
TCP/IP addresses/configuration (gateway, network masks)
Setting to box-to-box
Standard: 9600,8,N,1
Modification of hardware handshake ➟ without handshake
●
ISP-COM connection with 9P/9P twisted serial cable. Robot connection with
standard 9P/25P cable.
Connection of the COM servers takes place via a normal LAN.

10.7 Information on Fujitsu libraries
The control computer of FUJITSU libraries is the PLP. All settings for the FUJITSU library
are made on this, such as adding or deleting clients.
This is done with the lmadmin program which is contained in the
/opt/FJSVlmf/bin directory.

10.8 Information on LTO drives
Carrying on recording physical tapes shall only be done on physical drives of one manufacturer and only for the last and identical LTO generation. This needs to be considered for
tape drives assigned to a tape library in ETERNUS CS HE.
This means for example:
–
In the tape library TL0, to which also physical volumes of a physical volume group PVGx
are assigned, HP LTO-4 und IBM LTO-4 shall not be activated simultaneously when performing a save, because updates on devices of different manufacturers is not guaranteed.
–
In a tape library, physical drives of type IBM LTO-4 and IBM LTO-2 shall not be activated
simultaneously when performing a save.
10.9 Information on cascading with CentricStor V3.x systems
The following must be borne in mind when an CentricStor V3.x system is used as a cascading destination:
If an FC controller of an IDP of the cascading source (V5.0 system) is connected directly
(not via an FC switch) to an FC controller of an ICP of the cascading destination (V3. system), LOOP mode must be configured for every such FC controller in the V3.x system.
This change is necessary irrespective of whether this connection is used by PLS or PDS.
406
Information on cascading with CentricStor V3.x systems
The setting is made using the GXCC menu Configuration ➟ FC Boards. The FC controller’s
Mode parameter must be switched from AUTO to LOOP. Distribute and Activate must then be
executed.
407
10.10 Fibre channel switches in the SAN environment
10.10.1 Features of the FC connection
408
●
Provided that no direct point-to-point connections between host and ETERNUS CS
HE/ICP are used, all components of the SAN can be connected via a fibre channel
switch to the ETERNUS CS HE ICPs. The (brocade) switch works here with zoning
which can be configured via Telnet or Internet Explorer. For more information, see
section “Zoning” on page 409.
●
Startup sequence: The FC switch must always be switched on first and then the
ETERNUS CS HE ICPs. If you do not switch on in this sequence FC_AL will be
activated instead of FC point-to-point.
●
If a Linux 8.0 host shares an ICP host connection with other systems (Linux or other),
no part of the configuration may be changed while the system is running. This includes
reboot and shutdown processes of one of the hosts.
●
Regardless of the switch type used, it is advisable to set the transmission speed
explicitly for the port employed with the portcfgspeed command.
●
If an FC switch Brocade 4100 is used internally or externally in an ETERNUS CS HE
system, problems can occur in the automatic recognition of the FC topology (LOOP
instead of fabric). The problem can be solved by explicitly preventing the use of LOOP
on the port employed: The switch command portcfggport ensures that LOOP initialization does not take place. You can obtain information about this using the help
command.
10.10.2 Zoning
10.10.2.1
Rules
–
–
The SAN switch must be independent and must not be linked to the internal switch from
ETERNUS CS HE.
There are 2 different ways to configure zoning:
1. Port zoning (recommended for ETERNUS CS HE)
2. WWN zoning
Port zoning obliges the use of a strict, but advantageous cable plan. It does not require
any changes to be made to the configuration of the switch when host bus adapters are
exchanged. With WWNN-Zoning, defective GBIC ports can be changed without reconfiguring.
–
–
–
–
Each zone may contain only one point-to-point connection to a host, so that if there is
an error in a host bus adapter, further connections are not broken.
While a new zone configuration is being activated, there should be no data traffic in the
whole fabric.
The rule that you should not have any overlapping zones on a device (here the ICP),
must be broken. You must break the rule in order to enable ICP-Sharing by different
hosts.
Only connections that are strictly necessary should be created.

Diagnostics in the event of performance problems
When performance problems occur it may be necessary to look at the data throughput in a
ETERNUS CS HE system. The easiest way to ascertain the values is on the internal FC
switch. With Brocade switches this is possible using telnet.
Use telnet to go to the switch under the admin ID. You must ask the service provider for
the password for admin. The FC switches a defined under the names FCS0 through FCS3
in the /etc/hosts file.
The following commands can be used to read out information:
fabricshow
Shows the fabric configuration
switchshow
Shows the configuration of the ports and connected WWPN. Interconnect connections and FC speeds are displayed.
zoneshow
Shows the configured and active zones (switch on the frontend or
backend)
portperfshow
Shows the performance on the various ports and Interconnect connections
The session is terminated with the logout command.
If Brocade switches are also installed on the SAN side it is also possible here to perform
objective analyses using the commands mentioned above. In this case the Interconnect
connections in particular must be looked at specifically as they occassionally present a bottleneck.

10.12 Example of a filter bridge for separating ETERNUS CS HE
10.12.1 General
The problem that customers want to be certain that ETERNUS CS HE does not open a back
door into their computer centers repeatedly raises its ugly head. One approach to solve this
is a filter bridge between ETERNUS CS HE and the rest of the computer center on the basis
of a
LINUX PC. The following is intended as an aid to solving this problem.
●
A conventional PC with at least 2 network interfaces can be used.
●
The LINUX system used in the ETERNUS CS HE development was, for example, SuSE
SLES9 Rcxx. Linux 2.6.5-7.97 is supplied as the kernel, and this is sufficient. However,
the userland commands brctl and ebtables are not available. These were
obtained from the Internet as a source and compiled and installed.
●
The system contains the start/stop script bridge which you can copy with cut&paste to
the /root ID, for example. The commands are then:
Start:

The bridge configuration is also available on the system and should be copied under
the ID /etc/sysconfig, otherwise the bridge script must be adjusted. Adjustments are
only required in this configuration file. You have a free hand in designing the set of rules
RULES_xx, provided you bear in mind that the set of rules is interpreted/evaluated
several times by the shell before it is executed. It is advisable to use the example below
as a guide.

10.12.4 Ports used by ETERNUS CS HE
The TCP and UDP ports used by ETERNUS CS HE are described in section 4.2.1 Network
services of the User Guide [1].
428
Long distance over an FCIP connection with Cisco Switch
10.13 Long distance over an FCIP connection with Cisco Switch
FCIP connections can be established using Cisco Switches / Directors of the MDS-9000
family.
FCIP is a storage networking technology (RFC 3821) based on the Internet protocol which
enables FC data to be tunneled via IP networks.
10.13.1 Long distance over an FCIP connection between the internal Brocade
Switches of ETERNUS CS HE with CMF
To permit a catastrophe-resident solution, two VSANs are required which should also have
two redundant connections in the WAN to ensure redundancy.
The VSANs are created via the CISCO LAN/WAN. In the example below, FCS0 has a connection to FCS1 via VSAN10, and FCS2 has a connection to FCS3 via VSAN11.
429
10.13.1.1
Configuration settings
i
Important for the CISO-FCIP configuration: the IOs within ETERNUS CS HE may
not be interrupted in order to prevent the ETERNUS CS HE mirror from being split.
If only one connection between the sides exists, the ETERNUS CS HE ISPs must be shut
down - a vtcon stop is not sufficient.
Cisco settings
●
A VSAN without zones
●
Firmware status >= 3.1.2 required
●
MTU (Maximum Transmit Unit) Frame Size:
The default size is 1500. You are recommended not to change the pathmtu enable setting; this is used to calculate the best MTU size automatically.
Not all network connections support an MTU size > 1500.
●
Sets Write acceleration for FCIP
●
Interoperability Mode in the Cisco Switch/Director 3
●
Sets ISL Port to E (E_port)
Example
CISCO configuration via CLI for ports 1 and 2, and on Cisco Switch1:
config t
interface fc 1/1 -2
portmode E
switchport trunk mode off
switchport speed 4000
switchport rate-mode dedicated
no shutdown
exit
config t
vsan database
vsan 10 interop 3
vsan 11 interop 3
no shutdown
exit
430
Brocade settings
In the default configuration, ports 2 and 3 on the FC switches are provided as an ISL connection.
When additional bandwidth is required for the ISL connections, additional ports can be
used. The settings used in the example must be specified here.
The following settings must be made and if necessary checked in the internal FC switches
FCS0,1,2 and 3:
–
Interoperability Modes remains in Native Mode
–
PID format must be 1. This can be checked with:
configshow: fabric.ops.mode.pidFormat
–
Longdistance is enabled via the switch configuration:
FCS0:admin> switchdisable
FCS0:admin> configure
Fabric parameters (yes, y, no, n): [no] y
…
…
Long Distance Fabric: (0..1) [0] 1
●
For Brocade FabOS < 6.3
Set ISL Mode for ports 2 and 3:
portcfgislmode 2 1
portcfgislmode 3 1
Define Speed as max. 4G:
portcfgspeed 2,4
portcfgspeed 3,4
Disable Trunking:
portcfgtrunkport 2,0
portcfgtrunkport 3,0
Enable Long Distance (e.g. 20 km):
●
portcfgloongdistance 2,LS,0,20
portcfglongdistance 3,LS,0,20
For Brocade FabOS 6.3 and higher
Disable Quality of Service:
portcfgqos
portcfgqos
Disable Credit Recovery:
portcfgcreditrecovery - - disable 2
portcfgcreditrecovery - - disable 3
- - disable 2
- - disable 3

Note
The master decides centrally that volumes are to be set to scratch. As the master is the
Authorized User, it can do this without taking over ownership of the volumes.
Mutual access to the volumes by the media servers is prevented by the ownership.
When a volume is released, it can be selected by any media server.
A volume either has one owner or is unowned.
449
10.14.3 Ownership of a volume
Assigning the ownership of a volume
●
By entering the volume in a volume range for a client in the VACS configuration (initial
ownership of volumes).
!
CAUTION!
This applies only when an owner is set for the first time for a volume, otherwise
the ownership is not changed.
Check using volrpt.
●
By assigning ownership using the cmd_proc subcommand: set owner
●
Using rules for transferring ownership when the following activities are performed: mount
scratch, set scratch, set scratch reset.
When the status changes from scratch to data you can, for example, define that the
mounting user is to become the new owner.
A specific mount for a volume from a scratch pool is handled like a mount scratch.

Definition and meaning of the Userid in the ACSLS
The Userid discussed here has nothing to do with a user account at operating system level.
It is defined in the backup tool for ACSLS accesses; the default is the host name or empty
(““).
Whether an ACSLS Userid can be set depends on the backup tool:

10.14.3.3
Special features when using the VACS security rules
Definition of the Userid for the host
In VACS the Userid used by the backup tool which is employed for ACSLS requests must
be entered. All is not permitted. Most backup tools use ("") or the host name for ACSLS requests.
VACS replaces the empty entry by the first entry found. It is therefore recommendable to
enter the host name as the Userid if no explicit Userid is known.

Use of the Authorized Userid by customer applications
Example with NetBackup
Each master server has overall control of the volumes of its media servers.
A media server is always assigned to one customer. In terms of volume accesses, the media servers should be separated from each other. The master server can access all volumes
of its mefia servers.
The master server returns thevolumes to the VACS scratch pool as unowned when they have
been released.
Another media server fetches an unowned volume from the scratch pool. This media server
then becomes the owner of this volume.
This mechanism is implemented using the Netbackup tool robstat.
This is only possible for one instance ETERNUS CS HE.
Example with NetBackup or TimeNavigator
There are multiple applications.
Each application has a primary and a secondary master server.
Each master server is responsible for a number of media servers.
The VACS scratch pools are not used.
Multiple NetBackup and TimeNavigator instances access an ETERNUS CS HE.

The installation descriptions on the CD may be more up-to-date than the descriptions in this Integration Guide.
11.2 Installation descriptions
This CD-ROM can be used to install the GUI software required for the monitoring of an
ETERNUS CS HE system. The GUI software was tested on the operating systems MSWindows 95/98/NT/2000/XP/VISTA, LINUX and SOLARIS. The software to be installed
includes the base software Tcl/Tk and the GUI software components GXCC and XTCC. In
the following the procedures for installing the software packages on the various operating
systems are described.
455
Installation descriptions
Installation of the GUI software GXCC/XTCC
11.2.1 Installation on MS-Windows Platform
The operating systems supported are MS-Windows 95/98/NT/2000/XP and VISTA. On
these platforms the base software Tcl/Tk is integrated in the GUI software packet (GXCC
and XTCC). Versions of Tcl/Tk, including all associated links, that are already installed at
the time of installation, are not affected by the installation process per se. Any available
configuration data in the file hosts.txt will automatically be saved.
On a multi-user system (such as MS-Windows NT/2000/XP/VISTA), the installation
and deinstallation must be performed under an administrator account. However, the
programs can be started from any account via the menu Start. Certain administrative functions, however, do require an administrator account.
i
Names of files and directories can be displayed by MS-Windows in different ways
(e.g. name.ext, Name.ext, NAME.EXT). This has, however, no significance.
Names of folders, window titles, button labels and message texts depend on the
language option of MS-Windows and may deviate from this description.
Information about unattended installation can be found in section “Unattended Installation
/ Deinstallation under MS-Windows” on page 470.
11.2.1.1

ETERNUS CS HE
Using a selection window, it is possible to exclude specific components from the installation
process.
Should the tools required for the installation and deletion of CA-Unicenter extensions on MS-Windows NT/2000 Systems be needed, then the CA Unicenter
Integration Tools components must not be deselected.
i
By selection of the component GXCC Demo (FALKE) the snapshot files required for
the offline mode (refer to section “Offline Mode” on page 466) will be included.
During the installation of the GUI software, the user will be guided through the process by
means of various self explanatory dialogue windows. All individual windows containing the
buttons Next or Install must be acknowledged. In the concluding window Setup has finished
installing... the user can decide to Import V6 User Data (if available) and to Uninstall V6 Control
Center (if present). The installation will be terminated by clicking the Finish button.
11.2.1.2
Installation of the GUI documentation (optional)
The GUI software includes the capability to automatically access, provide and update the
online documentation for the ETERNUS CS HE system being monitored. The documentation of the GUI programs GXCC and XTCC can optionally be installed to ensure that it is
accessible even when no connection has been established to an ETERNUS CS HE system
(offline-mode). Depending on actual availability it consists of the complete ETERNUS CS
HE service and/or user manual or it consists of selected chapters, concerning the graphical
user interface.
CAUTION!
Because the documentation will be copied into the folder doc of GXCC, it is
important to perform the following steps after the installation of the GUI software
(section “How to proceed” on page 456):

11.2.1.4
Creating the CA-Unicenter Extensions for ETERNUS CS HE
During the installation of the GUI Software, various tools for the installation and deletion of
the CA-Unicenter extensions are installed provided that the CA Unicenter Integration Tools
components has not been deselected.
On a multi user system (MS-Windows NT/2000/XP/VISTA), these tools can only be installed
under the account of the user (with administration privileges) who installed the GUI
Software.
Guidance for the operation will be given by invoking Start ➟ Program Files ➟ Fujitsu ➟
ETERNUS CS Control Center V7 ➟ Setup ➟ SNMP Integration Readme.
For the installation of the extensions the tool Start ➟ Program Files ➟ Fujitsu ➟ ETERNUS CS
Control Center V7 ➟ Setup ➟ Add ETERNUS CS to CA-Unicenter should be invoked. This tool
copies all files necessary for the operation of the CA-Unicenter to the appropriate directories.
By invoking Start ➟ Program Files ➟ Fujitsu ➟ ETERNUS CS Control Center V7 ➟ Delete
ETERNUS CS from CA-Unicenter the extensions can be deleted.
11.2.1.5
Deinstallation of the Software
After invocation of Start ➟ Program Files ➟ Fujitsu ➟ ETERNUS CS Control Center V7 ➟ Setup
➟ Uninstall ETERNUS CS Control Center a window with the title 'Fujitsu ETERNUS CS
Control Center V7 Uninstall' will be displayed asking 'Are you sure that you want to
completely remove Fujitsu ETERNUS CS Control Center V7 and all of its
components ?'. Pressing Yes starts the deinstallation of both, the GUI software and the
documentation. By pressing No, deinstallation can be cancelled. Any available configuration
data in the file hosts.txt will automatically be saved.
Information about unattended deinstallation can be found in section “Unattended Installation / Deinstallation under MS-Windows” on page 470.
11.2.1.6
Configuration Data
During the course of the installation, a check is made as to whether the configuration data,
contained in the file hosts.txt, already exists in the associated directory. If this is not the
case, a search is made for configuration data which were saved during a possible previous
deinstallation process. If a previous version, in violation of the recommended procedures,
was not deinstalled and thus no configuration data was saved, then the configuration data
in the file hosts.txt must be copied manually from the directory
<Installation_path_old\xtcc\tmp> to <Installation_path_new\xtcc\tmp>.
459
11.2.2 Installation on a LINUX Platform
On this platform the base software Tcl/Tk is integrated in the GUI software packet (GXCC
and XTCC). Versions of Tcl/Tk that are already installed at the time of installation are not
affected by the installation process per se.
The package names for the GUI software of ETERNUS CS HE V4 and higher have
changed. Before installing this GUI-Software the GUI packages of any older version
must be deinstalled.

GXCC and XTCC are started via command line input. The user can specify the operation
mode as start parameter. For GXCC the program gxcc, and for XTCC the program xtcc
should be invoked. Start in service mode, observe mode, or user mode is accomplished via
options -service, -observe, or -user. Without any option specified the program is
started in user mode.
Syntax of command line input:
gxcc [-service | -observe] [&]
xtcc [-service | -observe] [&]
i
11.2.2.3
If the Linux server is accessed via a VNC client and if IPv6 is activated on the Linux
server, the environment variable DISPLAY contains IPv6 format of the server IP
address (e.g. ::1:1.0, ::ffff:127.0.0.1:1.0). In this case the variable DISPLAY
must be provided with IPv4 format of the IP address (e.g. 127.0.0.1:1.0) or with
the hostname (e.g. localhost:1.0) to ensure starting the GUI software.
Deinstalling the GUI Software
The deinstallation has to be performed under the user account root in the following
sequence:
1. rpm -e fsc-GlbDoc
2. rpm -e fsc-GlbXtcc
3. rpm -e fsc-BrkXtcc
11.2.3 Installation on a SOLARIS Platform
The installation has to be performed under the user account root of the SOLARIS system.
On this platform the base software Tcl/Tk is integrated in the GUI software packet (GXCC
and XTCC). Versions of Tcl/Tk that are already installed at the time of installation are not
affected by the installation process per se. The installation has been tested with SPARC
SOLARIS Version 9 (english). In other SOLARIS versions the procedure may differ.

Online Documentation of the GUI Software
11.3 Online Documentation of the GUI Software
11.3.1 General
The GUI software includes the capability to automatically access, provide and update the
online documentation for the ETERNUS CS HE system being monitored.
During the installation of the GUI programs GXCC and XTCC their documentation will also
be installed to ensure that it is accessible even when no connection has been established
to an ETERNUS CS HE system (offline-mode). Depending on actual availability it consists
of the complete ETERNUS CS HE service and/or user manual or it consists of selected
chapters, concerning the graphical user interface.
11.3.2 Displaying the Documentation via the Help Function of the GUI
The Help menu of GXCC and XTCC contains an entry for the GUI online documentation,
the text of which depends on the operation mode the GUI has been started with. After
starting in service mode, an entry CS <version> Service manual (complete) will be displayed,
if the complete service manual exists, or an entry CS <version> Service manual (GUI-Part) will
be displayed, if only the chapters concerning the graphical user interface are available.
In case of user mode and observe mode an entry CS <version>User manual (complete) will
be displayed, if the complete user manual exists, or an entry CS <version>User manual (GUIPart) will be displayed, if only the chapters concerning the graphical user interface are
available. The service mode will be handled like the user and observe mode if no service
manual is available.
Invoking this function leads to the display of the service or user manual with a PDF viewer.
For this purpose a PDF viewer must be installed on the system:
–
–
–
On a MS-Windows platform: Acrobat Reader
On a LINUX platform: xpdf or acroread
On a Solaris platform: acroread
!
464
CAUTION!
If the GUI software is started on a Linux system from a MS Windows system via Xserver, then the Online documentation display can cause the X-server to crash
when Acrobat Reader 4 is installed on the Linux system. This effect has not been
observed with Acrobat Reader 5.
Font Files
11.4 Font Files
11.4.1 General
When the GUI software uses a fixed font (monospaced font) to display window elements,
the preferred font (as from ETERNUS CS HE V4.0) is the TrueType font Bitstream Sans Vera
Mono, if this font is installed in the X Window system. Otherwise the font Courier, which
exists on all platforms, is used, as it has been in the past. Among other things, this new font
has the characteristic that the number 0 differs clearly from the character O.
During the installation of ETERNUS CS HE the font will be installed by default, and
therefore will automatically be used when the GUI software is started on the ETERNUS CS
HE console. If the GUI software is installed using the GUI CD on computers outside of
ETERNUS CS HE and the GUI should use the new font, the font must be installed on the
computer where the GUI software runs.
On the GUI computer the font may be installed at a later time. For this purpose the GUI CD
provides the related font files in the directory fonts. This directory is located in the root
directory of the CD-ROM.
11.4.2 Installation of the font files
The installation of the font files depends on the platform and must be executed manually in
the majority of cases.
11.4.2.1
Installation on MS-Windows Platform
The installation of the font files occurs automatically during the installation of the GUI
software.
11.4.2.2
Installation on a LINUX Platform
The installation of the font files has to be performed manually by the user. The procedure
depends on the Linux distribution used. The X Server has to be restarted in all cases at the
end of the font installation, so that the new font files may be used.
11.4.2.3
Installation on a SOLARIS Platform
The installation of the font files has to be performed manually by the user. The procedure
depends on the Solaris system used. The X Server has to be restarted in all cases at the
end of the font installation, so that the new font files may be used.
465
Offline Mode
11.5 Offline Mode
Usually the display generated by the GUI software is based on data, which are periodically
received from an active ETERNUS CS HE system. The communication partner within the
active system is the InfoBroker. For demonstration purposes the GUI software can take the
data from a file, and display the information of an inactive ETERNUS CS HE system,
described by these data. This way of operation will be called offline mode in the following,
the file will be called a snapshot file.
When GXCC is running on a system which does not contain the InfoBroker, a window Mode
Select will be automatically displayed to the user, containing an option button for setting the
operation mode. Via the option File the user chooses the offline mode, and in the window
File Select the user may determine the snapshot file. The user may use the default snapshot
file or select a snapshot file from an arbitrary directory via the button Browse. After determining the snapshot file the GUI software displays the name of the ETERNUS CS HE
system which is described by the snapshot file.
When GXCC is running on a system which contains the InfoBroker, the system described
will be displayed automatically. In order to choose in this case the offline mode one has to
invoke the function Open from the menu File of the GXCC window. Then the window File
Select will be displayed to the user, offering the functions described above.
During the installation of GXCC the directory TEST for snapshot files will be created. The
snapshot file gxtcc.gxd will be created in this directory. It is proposed as default in the
window File Select. Additional files are provided on the CD-ROM for demonstration
purposes. They have to be copied manually into the appropriate directory in order to use
them.
11.5.1 Integrating the Snapshot Files
In the following the procedures for copying the snapshot files onto the various operating
platforms is described under the appropriate headings.
466
11.5.1.1
Offline Mode
MS-Windows Platform
The following steps are only required, if during installation setup of the GUI software
the component GXCC Demo (FALKE) has been deselected; otherwise the additional
files are already present.
i
The installation is to be done as follows:
1. Insert the CD-ROM into the CD drive if not already done.
2. Open the Windows directory on the CD and double click the left hand mouse button on
the file gui87en.exe.
i
Control is active.
3. The displayed Installation directory must be incorporated using the Next button.
4. A window appears with the title Directory Exists followed by the message 'The
directory '<Installation_directory>' already exists. Would you like
to install to that directory anyway ?' This question should be replied to in
the affirmative by means of Yes.
5. By selecting the component GXCC Demo (FALKE), the additional installation of the
necessary snapshot files is prepared.
6. All subsequent windows are to be acknowledged with the Next or Install buttons.
7. In the final window Setup has finished installing... clicking on the Finish button concludes
the installation process.
11.5.1.2
LINUX Platform
1. Mount the CD-ROM on the file system:
mount <directory for the CD drive>
Example: mount /media/cdrom
2. Select the CD-ROM directory which contains the snapshot files:
cd <directory for the CD drive>/demo/TEST
Example: cd /media/cdrom/demo/TEST
3. Copy all snapshot files (including directories) into the directory prepared by GXCC:
cp -r * /usr/apc/gxtcc/TEST
467
Offline Mode
11.5.1.3
SOLARIS Platform
In case of operating the system via the CDE user interface a window File Manager will
be displayed automatically with the directory of the CD-ROM.
2. Open the directory demo by double clicking the icon of this directory with the left mouse
button.
3. Open the directory TEST by clicking the icon of this directory with the left mouse button.
4. Select all files and folders by invoking the function Select All in the menu Select within the
window File Manager of the CD-ROM.
5. Open a new window File Manager for the target for the snapshot files via the workspace
menu of the desktop (i.e. positioning the mouse pointer on the desktop background and
pressing the right mouse button). There the function File Manager has to be invoked
within the submenu entry Files.
6. Open the target directories /opt/SMAW/SMAWLglb/gxtcc/TEST, by opening sequentially all directories of this path by double clicking the icon of each directory with the left
mouse button.
7. Copy the highlighted snapshot files via drag&drop into the target directory. All
highlighted files implicitly are also transferred.
8. Close the window File Manager for the target of the snapshot files.
9. Release the CD-ROM by invoking the function eject in the menu File in the window File
Manager.
As an alternative to the CDE user interface, the command line interface requires the
following procedure:
1. Select the directory of the CD:
cd <directory for the CD drive>
Example: cd /cdrom/cdrom0
2. List the content:
ls
3. Select the CD-ROM directory containing the snapshot files:
cd demo/TEST
4. Copy all snapshot files (including directories) into the directory prepared by:
cp -r * /opt/SMAW/SMAWLglb/gxtcc/TEST
5. Release the CD-ROM via the command eject in the root directory.
468
Offline Mode
11.5.2 Functionality in Offline Mode
The data of a snapshot file reflect either a snapshot or a maximum 2 hour period of the
history of an ETERNUS CS HE systems. The covered time period determines whether the
display in the Global-Status-Monitor is static or dynamic. In case of a static display the
picture does not change, since the data only reflect a single point in time. In case of a
dynamic display the picture is updated periodically, according to the data which correspond
to the period currently reflected.
Both kinds of snapshot files can be distinguished by the name suffix. A file with the suffix
gxd contains a single snapshot only, whereas a file with the suffix db covers a whole period.
11.5.2.1
Static Display
Starting GXCC in offline mode will always display a static picture of an ETERNUS CS HE
system. For each ISP in the display there is a function menu provided containing the
function Show Details (XTCC), which opens a XTCC window in offline mode and displays a
static picture of the concerned ISP.
In the menu Tools of the GXCC menu bar the Global-Status-Monitor can be started. If there
is only one snapshot file of type gxd of the concerned system (i.e. there is no additional file
*.db), the stored operational data are only displayed in a static picture. The display of
performance data is not included, because it only reflects a snapshot.
11.5.2.2
Dynamic Display
If a snapshot file of type db exists for the system already being displayed in GXCC, then the
GXCC-Recorder tool will be activated when the Global Status Monitor is started in offline
mode. This tool delivers to the Global Status Monitor periodically the operational data which
are stored in the snapshot file for the concerned time period. The Global Status Monitor
updates the display according to the data delivered. When operational data changes,
changes become visible in the picture displayed by the Global Status Monitor, but not in
GXCC.
The tool GXCC Recorder also supports the sequential display of snapshot files of different
systems (this is called ROTATE mode). In order to do so the user has to select the corresponding snapshot files of type db within the application window of the GXCC Recorder.
When a snapshot file changes, then the GXCC display changes also.

11.6.2 Setup Exit Codes
0
Setup was successfully run to completion.
1
Setup failed to initialize.
2
The user clicked Cancel in the wizard before the actual installation started.
3
A fatal error occurred while preparing to move to the next installation phase (for
example, from displaying the pre-installation wizard pages to the actual installation
process). This should never happen except under the most unusual of circumstances,
such as running out of memory or Windows resources.
4
A fatal error occurred during the actual installation process.
i
Errors that cause an Abort/Retry/Ignore box to be displayed are not fatal errors.
If the user chooses Abort at such a message box, exit code 5 will be returned.
5
The user clicked Cancel during the actual installation process, or chose Abort at an
Abort/Retry/Ignore box.
6
The Setup process was forcefully terminated by the debugger (Run or Terminate used in
IDE).

Before returning an exit code of 1, 3, or 4, an error message explaining the problem will
normally be displayed. Future versions may return additional exit codes, so applications
checking the exit code should be programmed to handle unexpected exit codes gracefully.
Any non-zero exit code indicates that Setup was not run to completion.
11.6.3 Uninstaller Command Line Parameters
The uninstaller program unins000.exe accepts the following command line parameters:
/SILENT
When specified, the uninstaller will neither ask the user any questions nor display a
message stating that uninstall is complete. Shared files that are no longer in use are
deleted automatically without prompting.
Any critical error messages will still be shown on the screen. The uninstallation progress
window is displayed.
/VERYSILENT
When specified, the uninstaller will neither ask the user any questions nor display a
message stating that uninstall is complete. Shared files that are no longer in use are
deleted automatically without prompting.
Any critical error messages will still be shown on the screen. The uninstallation progress
window is not displayed.
/SUPPRESSMSGBOXES
Instructs the uninstaller to suppress message boxes. Only has an effect when combined
with /SILENT and /VERYSILENT.
11.6.4 Uninstaller Exit Code
The uninstaller will return a non-zero exit code if the user cancels or a fatal error is encountered. Programs checking the exit code to detect failure should not check for a specific nonzero value; any non-zero exit code indicates that the uninstaller was not run to completion.
Note that at the moment you get an exit code back from the uninstaller, some code related
to uninstallation might still be running. Because Windows doesn't allow programs to delete
their own EXEs, the uninstaller creates and spawns a copy of itself in the TEMP directory.
This clone performs the actual uninstallation, and at the end, terminates the original
uninstaller EXE (at which point you get an exit code back), deletes it, then displays the
uninstall complete message box (if it hasn't been suppressed with /SILENT or
/VERYSILENT).

12 Web GUI for ETERNUS CS HE administration
As of ETERNUS CS HE V5.0A a web based graphical user interface is supplied for administration of ETERNUS CS HE.
This GUI offers all functions necessary for media management (i.e. LV, LVG, PV, PVG).
The Web GUI does not need any further software to be installed and can be used on common operating systems with Firefox (version 2 and 3) or Internet Explorer(IE7 and IE8), also
on the ETERNUS CS HE console.
For detailed informationen about operating and monitoring via the Web GUI please refer to
the User Guide or the Online help (after having started the Web GUI and successful login
to a ETERNUS CS HE system).
12.1 Starting the Web GUI
To permit communication between the client (browser) and the CS-WEB application in the
ETERNUS CS HE cluster (Web server), the Web server supports both the customary HTTP
connection, in which all data is transferred between the client and the server in unencrypted
form, and an encrypted HTTPS (SSL) connection.
Proceed as follows to start the Web GUI in the mode you require:
1. Call the Web browser.
2. Enter the address in the Web browser:
–
http://<host>/eternus-cs for unencrypted transmission
–
https://<host>/eternus-cs for encrypted transmission
Enter the host name or the IP address of the VLP in place of <host>.
3. Click on [Enter].
Once you have started the Web GUI successfully, the login window is displayed (see section “Logging in” on page 476).

13 Application recommendation for ETERNUS CS
HE Update Installation
This chapter provides the service engineer and the administrator of the front-end application with the necessary decision information what update procedure shall be chosen and
also acts as an example and guideline for the rolling update of an ETERNUS CS HE cluster.
13.1 General information
The rolling software update is a flexible basic procedure via which the software update for
ETERNUS CS HE systems can be executed interrupt-free for the front-end application.
One or a number of CS nodes are installed while the remaining nodes maintain operations.
The non-interruption for an active front-end application presumes that this application is
available on at least 2 ICPs or 2 IUPs, that it is SWAP master resistant in its LAN robot
connection, that it can also execute an interrupt-free switchover between these connections
and that administrative interfaces permit the implementation of such switchovers.
If this is not fulfilled, running jobs are aborted. As ETERNUS CS HE operations are not
interrupted during the rolling update, non-plannable recovery runs are possible at any time.
Plannable backup jobs should be terminated before starting the rolling update.
As an alternative to the interrupt-free rolling software update, ETERNUS CS HE always
offers the option of a so-called cluster update where the CS nodes are basically updated
simultaneously. This procedure requires much less time for the update but also a (short)
downtime of the entire system. Values for the time required for the software update via the
various procedures are compared in the section Update assessment criteria.
In specific situations, the decision for a particular update procedure should be based on
weighing up the customer's priorities and the features of the backup applications used.
479
Update procedure
Application recommendation for ETERNUS CS HE Update Installation
13.2 Update procedure
The decision about the update procedure used is supported by the software update
program (updmc). It determines the possible update options based on the software version
already installed on the system and the new updates to be installed. The service engineer
makes the final decision about the recommended procedure to be used based on customer
requirements.
13.2.1 Online update
The online update installation is a fully automatic, interrupt-free update procedure where an
ETERNUS CS HE service is not interrupted. ETERNUS CS HE system redundancy and
failsafe is not restricted at any time. This method assumes that the components of the
operating system kernel, the CAFS and the central ETERNUS CS HE components are not
affected by the update installation.
13.2.2 Rolling update
The rolling software update is a flexible basic procedure via which the software update for
ETERNUS CS HE systems can be executed interrupt-free for the front-end application.
One or a number of CS nodes are installed while the remaining nodes maintain operations.
The non-interruption for an active front-end application presumes that this application is
available on at least 2 ICPs or 2 IUPs, that it is SWAP master resistant in its LAN robot
connection, that it can also execute an interrupt-free switchover between these connections
and that administrative interfaces permit the implementation of such switchovers.
13.2.3 Split cluster update
In typical 2-site ETERNUS CS HE configurations the CS system is symmetrically
distributed over two locations and the applications connected redundantly. In this case, the
so-called split cluster update is also an interrupt-free rolling update configuration
optimized for front-end applications via which all ISPs of a location are simultaneously
installed. The other location runs the ETERNUS CS HE and backup activities of the frontend applications for this period.
480
Update situations
13.2.4 Cluster update
As an alternative to the interrupt-free rolling software update, ETERNUS CS HE always
offers the option of a so-called cluster update where the CS nodes are basically updated
simultaneously. This procedure requires much less time for the update but also a (short)
downtime of the entire system, i.e. all applications must be ended before starting the
cluster update. Values for the time required for the software update via the various procedures are compared in the section Update assessment criteria .
13.3 Update situations
Depending on the existing update conditions, the service engineer must decide for one of
the software update procedures recommended by the update tool updmc:
●
●
●
Online update
Condition:
The update medium (hotfix/patch CD) fulfills all the criteria for the online
update.
Execution:
fully automatic via the update program updmc, a decision by the service
engineer is not required.
Rolling update
Conditions:
The rolling update must be performed interrupt-free on oneor a number
of CS nodes (see section “Rolling update” on page 480).
The update program updmc has recommended rolling update as a
possible update procedure.
Execution:
The service engineer performs the rolling update according to the
Update handling instructions section “Rolling Update” on page 491.
The service engineer can decide to use the cluster update (with
downtime).
Split cluster update
Conditions:
The update program updmc recommends the rolling update as a
possible update procedure and the CS system is symmetrically
distributed at two locations and the applications are connected symmetrically and redundantly.
Execution:
The service engineer executes the software update according to the
Update handling instructions - “Split cluster update” on page 492.
Alternatively, the service engineer can decide to use the cluster update
(with downtime).
481
Update assessment criteria
●
Cluster update
Conditions:
A maintenance slot with CS downtime is available to the service
engineer
Execution:
The service engineer continues the software update program updmc
with c (continue). The update is executed automatically.
The post update actions are executed by the service engineer according
to the instructions in the update program updmc, .
13.4 Update assessment criteria
13.4.1 Planning and administration expenditure
In order to estimate the planning and administration expenditure involved in implementing
the rolling update, the type and configuration of the front-end applications to be operated
are of decisive importance. In order to perform the SW update for the front-end applications
interrupt-free, it must be ensured when configuring the front-end application that the tape
devices are distributed at various ICPs.
It should also be noted that the front-end applications can be be re-connected differently
regarding the LAN robot connection. (see table “Front-end applications in an ETERNUS CS
HE environment” on page 483, Column: SWAP Master Resistant).
An overview of the currently most common front-end applications is in table “Front-end
applications in an ETERNUS CS HE environment” on page 483. Should an application be
used which is not listed here, Fujitsu Technology Solutions Product Planning must be
contacted beforehand.
The first two columns show the front-end application and the operating system used. The
column ’Pending’ Device Deactivation shows whether the deactivation of the drives belonging
to the ICP/IUP can be requested in backup/restore mode.
The column SWAP Master Resistant shows whether the reconnection of the LAN library
(VDAS, VACS, VAMU) after swap master on VLP or IUP, can take place in the application
without any problems, e.g. in the mount requests hanging in the application.
The column Handling instructions describes the activities for the service engineer and the
administrator for the respective front-end application.

13.4.2 Complexity
As can be seen in the table above, the complexity of the operation from an application pointof-view is defined by the number and type of applications and the size of the backup configurations on the front-end.
The rolling update must be viewed as a basic mechanism which is the prerequisite for
interrupt-free application operation subject to the conditions described above. The
additional support required by the data center administration regarding the coordination of
the individual instances affected by the update must be clarified beforehand. Decisive is
●
whether the ICP/IUP to be installed can be simply switched off as the affected applications must "survive" this downtime via redundancy and the corresponding symmetrical
configuration of the devices without any interruption to the backup operation.
●
whether the devices for the applications involved are easy to disable/detach and subsequently enable/attach so as to to automatically restart backup operations,
●
manual interventions in the application by the system administrator are required, in
agreement with the service engineer, to place the device affected by the ICP/IUP
update to the status that permits a detach/attach,
●
whether a mixture of all previously named options exists and the coordinated decommissioning is therefore linked to a high amount of work for the administrator or
485
whether, in the worst-case, deactiving individual ICP/IUPs is not even possible due to
the existing configuration which thus leads to unforeseeable system statuses in the
application.
●
The conditions listed show that detailed planning is essential before implementing the
rolling update in order to guarantee no interruptions during the update.
13.4.3 Total duration and downtime
This section compares the time required for the update versions rolling update, split cluster
update and cluster update (with downtime).
The service engineer must decide whether he wants to or must execute an interrupt-free
update for the application via rolling update / split cluster update for a longer time slot or
whether he wants to execute the automatic update with a restricted downtime in a slot that
is as short as possible.
13.4.3.1
Time required for the rolling update
A backup of the current system partition of the ISP must be made before the update.
The time required for the rolling update of a CS cluster is as follows.
●
The first update step is that the installation program itself is updated on all ISPs and the
installation servers and SW repository are loaded with the new software from the DVD.
●
The second update step is to consecutively update the software on all ISPs.

The time required for the split cluster update installation of a CS cluster is as follows.
–
A backup of the current system partition of all ISPs of the site affected by the update
must be made before the update.
The installation program itself is then updated online on all ISPs and the installation
servers and the SW repository are loaded with the new software from the DVD.
All ISPs at site A are subsequently updated.
When site A is fully operational again and the applications have been switched, site B is
updated.
Once site B is fully operational again, site C is updated.

The displayed pre-update action is
automatically executed.
5.3
For example:ssh ICP<n> reboot
The service engineer executes the
displayed post update action for the ICP.
If a reboot is requested as post update
action, it must be initiated using the
reboot-command on the ICP (not via vtcon
on the VLP master).

13.5.2 Split cluster update
i
492
The procedure for the split cluster update is described in the service manual,
section: Implementing the installation - split cluster update for models CS1500 and higher.
●
Assuming a symmetrical front-end connection, the front-end activities are transfered
simultaneously as described in the handling instructions “Example of the transfer of
front-end activities on the BS2000 S-server” on page 493 to all ICPs of a location, while
the other location maintains the current backup operation of the front-end applications.
●
The software is then jointly updated on all ICPs of this location; the front-end activities
of the other location are transferred and the update is run at the other location.
●
The symmetrical distribution of the front-end activities at the two locations is the
conclusion. The cluster status existing before the update is thus re-established.
13.5.3 Example of the transfer of front-end activities on the BS2000 S-server
A rolling update of the ETERNUS CS HE can be performed interrupt-free for the BS2000
application on the S server, if tape devices of at least two ICPs are available in the BS2000.
All front-end activities of this ICP must be transferred to another ICP before the rolling
update for an ICP can be started.
This is as follows based on the example BS2000 on an S-server, which executes its Archive
tape activities via the ETERNUS CS HE ISPs (ICP1 and ICP5):
●
The service engineer checks the front-end activities on ICP1 via the menu Global Status
Monitor in the GXCC. On the ETERNUS CS HE side, 16 emulations each are
configured on both the ICP1 and ICP5 (virtual components Emu ICP1 LibDevice:
50...5F , ICP5 LibDevice: 10...1F).
Read/write activities on
devices on ICP1
493
494
●
On the application side on the front-end on the BS2000 S Server, the administrator
can use the command show-device-depot' to check the logical devices in the depot (in this
example 50 -5F and 10…1F).
●
The administrator checks the existence of the logical devices (50 ..5F and 10...1F) in the
Robar SV configuration.
●
The administrator detaches the logical devices of the front-end application (belonging to
the ICP1) using the command det-dev *d(50,5F ). The currently used devices
change initially to the status detach-pending.
●
The service engineer checks whether the front-end activities automatically transfer to
ICP5 after detaching the devices on the ICP1. If this is the case, no further action is
required by the administrator. If this is not the case (possibly unanswered messages to
the BS2000 console), then the administrator must intervene and ensure that all frontend activities that previously ran on the ICP1 are now started on another ISP (here
ICP5).
The first device is
already mounted
on ICP5.
495
496
●
The administrator and the service engineer wait until all application backups/restores
have been transferred from ICP1 to ICP5 and devices are no longer attached with ICP1
(virtual components emu instead of previous turquoise running+attached is now green =
running)
●
As soon as all front-end activities have been ended on ICP1 (see above), the Service
Engineer starts the rolling update on ICP1 (Step 5.2 in table 5 on page 491)
●
The service engineer executes the post-update action for ICP1 (Step 5.3 in table 5 on
page 491)
Figure 1: Figure 7: CentriStor Status - reboot ICP1
●
The service engineer waits until the "post-update-activities" have ended on the ICP1 and
the ICP1 is actively functioning again in the ETERNUS CS HE cluster.
●
The administrator now attaches in the BS2000 all logical devices of the ICP1 via the
BS2000 command att-dev *d(50.5f) and checks via the show-device command
whether all of the devices are attached and assigned.
497
498
●
The service engineer waits until the front-end application integrates the devices on
ICP1 and mounts on its devices.
●
The rolling update on the first ICP (in this case ICP1) is thus completed.
●
The procedure must then be applied to all other cluster ICPs accordingly.

AutoVLP Failover Function
As the VLP Master plays a central role in the ETERNUS CS HE system, failure of the
VLP Master also causes the entire system to fail. To prevent this, a standby Standby
VLP (SVLP) can be integrated into the system as a backup computer. This SVLP is
inactive except for the monitoring function.
The AutoVLP failover function checks the functional integrity of the VLP Master at regular
intervals and, when it detects a malfunction, automatically takes the requisite steps: the
current VLP Master is split from the system and the SVLP is integrated into the system
as the current VLP Master. The system is then once more fully operational.

Cache
In the manual the term cache is sometimes used not only in its general sense but as a
synonym for Tape Volume Cache (TVC) or Tape Filesystem (TFS).
Cache Filesystem ➟ TFS
Cache Mirroring Feature ➟ CMF
Cache Policy
The Cache Policy is a feature of an LVG. It determines the behavior with regard to backup
in the TVC and to tape for the associated LVs. It can only be defined when a new LVG
is created. The following values are possible:
STANDARD:
TVC_RESIDENCE:
NO_BACKUP_TO_TAPE:
The logical volumes are displaced from the TVC according to an LRU algorithm if the memory space is required
for other purposes and after they have been
backed up to physical volumes.
The logical volumes are never displaced from the TVC,
even after they have been backed up to physical volumes.
The logical volumes are not backed up to physical volumes and can therefore never be displaced from the
TVC.
The default setting is STANDARD.
CAFS
The ETERNUS CS HE Appliance Filesystem (CAFS) is a cluster filesystem which, since CS
V4.0, has been used for the tape files systems of the TVC and also for the /DB and
/install2000 filesystems instead of DTVFS which was previously used under SINIXZ.
CAFS satisfies the ETERNUS CS HE requirements to a large degree, both in terms of
powerful processing of very large volumes of data and also in terms of data integrity and
availability even when hardware components are affected by a fault or fail completely.
CAFS enables ETERNUS CS HE operation to be maintained (apart from possible
reductions in performance) when the appropriate redundant configuration is provided,
even when disk faults occur, the RAID system crashes, one or more nodes in the cluster
crash, and faults occur in SAN and LAN communication, including complete failure of
the SAN.
501
Glossary
CAFS Cluster
A CAFS Cluster consists of CAFS Nodes, NSDs and a LAN which interconnects the
CAFS Nodes. An ETERNUS CS HE system forms a single CAFS Cluster.
When the CAFS Cluster is configured, a primary and a secondary Cluster Configuration
Server must be defined. The Cluster Configuration Server manages the information on
the CAFS Cluster Configuration and makes it available to all CAFS Nodes. When the
CAFS Daemon of a CAFS Node is started, it contacts the primary Cluster Configuration
Server (or the secondary Cluster Configuration Server if the primary does not respond)
to obtain the current data on the CAFS Cluster Configuration. Without this data it cannot
join the CAFS Cluster.
In order to prevent a split-brain situation in the CAFS Cluster when the SAN and LAN
are split into two or more parts, CAFS provides so-called Quorum Nodes and
Tiebreaker Disks. Provided more than half the Quorum Nodes are operating and can
be reached via the LAN, the CAFS Cluster is operational. In the models ETERNUS
CS500 and CS1000 both ISPs (IUP0 and IUP1) are configured as Quorum Nodes; in
the models ETERNUS CS1500 or higher both VLP ISPs (VLP0 and VLP1) and the
Tiebreaker Processor (TBP0) are configured as Quorum Nodes. When exactly half of
an even number of Quorum Nodes is accessible via the LAN, the Tiebreaker Disks
decide the issue. If the majority of the Tiebreaker Disks are available in this case, the
CAFS Cluster remains operational. Precisely one Tiebreaker Disk is configured for the
models ETERNUS CS500 and CS1000.
CAFS Cluster Configuration Manager
There is precisely one Cluster Configuration Manager in the CAFS Cluster. In the
models ETERNUS CS1500 or higher it executes on the VLP master.
When a CAFS Node crashes, the Configuration Manager decides whether a quorum
still exists and whether or not CAFS Cluster operation should continue.
CAFS Filesystem
A CAFS Filesystem is a filesystem of the type gpfs which is managed and maintained
by the CAFS. ETERNUS CS HE V4.0 or higher has not only the Tape Filesystems
(TFSs), but also /DB and /install2000 CAFS Filesystems.
CAFS Filesystem Manager
There is precisely one Filesystem Manager for each CAFS filesystem. In the models
ETERNUS CS1500 or higher it executes on the VLP master.
The Filesystem Manager implements status and configuration changes to the
filesystem, deals with mount and unmount requests and checks the efficiency of disk
utilization.
CAFS Node
A CAFS Node is an operating system map on a computer within a CAFS Cluster. In
ETERNUS CS HE each ISP is a CAFS Node, and vice versa.

cascading
With the cascading feature ETERNUS CS HE offers the option of using another
ETERNUS CS HE system which is connected via FC as the backend system. The
ETERNUS CS HE system used as the backend is called the cascading destination. The
ETERNUS CS HE system which uses the cascading destination is referred to as the
cascading source.
The main feature of the cascading source is that it uses PVs in native tape format
(➟ native tape format). This format corresponds to the original format of the LV when it
is transferred from the host applications to ETERNUS CS HE; it consequently contains
no metainformation.

FC
Fibre Channel (FC) is a standard which was designed for serial and continuous highspeed transfer of large volumes of data. It is also used in the Storage Area Network (SAN)
within ETERNUS CS HE and in some cases for the connections between the ICPs and
the hosts and between the IDPs and the back-end devices. The FC controllers used in
ETERNUS CS HE support bandwidths of between 1 Gbit/s (Gigabit per second) and
4 Gbit/s.
In the case of a Fibre Channel, each device has a WWNN (World Wide Node Name)
and each port of a device a WWPN (World Wide Port Name) as a unique worldwide
identifier. Each of these is a 64-bit address which is generally presented in hexadecimal
format as 8 bytes separated by colons.
A distinction is made between three types of Fibre Channel topologies :
–
–
–
Switched Fabric (FC-SW)
In the case of the Fibre Channel Switched Fabric, point-to-point connections are
switched between the channel via one or more FC switches.
Arbitrated Loop ( FC-AL)
In the case of the Fibre Channel Arbitrated Loop a logical bus is involved on which all
terminals share the same bandwidth. In ETERNUS CS HE, FC-AL can only be used
to connect back-end devices.
Point-to-Point (FC-P2P)
This refers to a direct connection between two terminals.
The FC Layer Model has 5 layers which have the following names:
–
–
–
–
–
FC-0 (Physical Layer)
FC-1 (Data Link Layer, coding/decoding the signals to be transferred)
FC-2 (Network Layer, flow control, service classes)
FC-3 (Common Services Layer, e.g. multicast, striping)
FC-4 (Protocol Mapping Layer, e.g. FCP, FICON)
FC Layer Model ➟ FC
FCIP
Internet-protocol-based storage networking technology (RFC 3821) which enables FC
data to be tunneled over IP networks.
FCP
FCP, like FICON, is a protocol of the uppermost layer FC-4 (Protocol Mapping Layer) in
the FC Layer Model. It defines how the SCSI protocol of the Application Layer above,
which is exchanged between the application and the terminal, is mapped onto the
services of the lower FC layers.
506
Glossary
FC Switch
An FC switch is the central component of an FC-based Storage Area Network (SAN). It is
capable of connecting each of the terminals which are connected in a star-shaped
configuration with any of the others and of guaranteeing a defined bandwidth for each
connection. The FC switches used for the internal SAN in the models ETERNUS CS500
and highter have 16, 24 or 32 ports.

Fibre Channel ➟ FC
Fibre Channel Protocol ➟ FCP

FICON
FICON, like FCP, is a protocol of the uppermost layer FC-4 (Protocol Mapping Layer)
in the FC Layer Model. It defines how the ESCON protocol of the Application Layer
above is mapped onto the services of the FC layers below.
Filegroup
Filegroup (FG) is an abstract configuration object - comparable with a Logical Volume
Group (LVG) in ETERNUS CS HE. A Filegroup represents a set of files in the filesystem
- more precisely: a subtree - and is a carrier of common attributes of these files. Among
other things, a Filegroup forms the basis of Shares which refer to the entire subtree represented by the Filegroup or parts thereof. Filegroups are disjunctive. In particular, Filegroups cannot be nested.
Filesystem Descriptor
The Filesystem Descriptor is a data structure with important descriptive data of a CAFS
Filesystem, such as the assigned NSDs, the current status and the references to the
logging files.
At least one Filesystem Descriptor exists for each CAFS filesystem. Depending on the
ETERNUS CS HE model, up to 3 replications are maintained, distributed over the various locations.
In the model ETERNUS CS50 only one Filesystem Descriptor exists for each CAFS filesystem.
In the models ETERNUS CS500 or higher a quorum is defined for each CAFS filesystem for the Filesystem Descriptor replications. If this quorum is fallen below, CAFS unmounts the filesystem concerned on all ISPs.

ISP
ISP (Integrated Standard Processor) is the general term for a processor which is used
in an ETERNUS CS HE system. Depending on the peripherals and the software configuration, a distinction is made between the following types of ISP:
ICP
NAS ICP
IDP
NAS IDP
ICP_IDP
TBP
VLP
VTC
ISP with host connection using ESCON, FICON and/or FCP.
ISP with LAN ports and two internal FC ports.
ISP without host adapter but with tape drives.
ISP with SAN interface and/or LAN interface for NAS filesystems.
This ISP type combines the attributes of ICP, IDP and VLP in one ISP. An
ICP_IDP has both a host adapter and a SCSI or FC controller to operate
real tape drives and robots. IUP (Integrated Universal Processor) is a
synonym for ICP_IDP
This ISP type is provided in the models ETERNUS CS1500 or higher. The
TBP (Tiebreaker Processor) is one of the three Quorum Nodes in the CAFS
Cluster. Its function is to prevent a split-brain situation.
Processors of this type always occur in pairs in the models ETERNUS
CS1500 or higher. Central management processes, in particular VLM and
PLM, run on one of the two, the VLP Master. The other, the Standby VLP
(SVLP), monitors the operating status of the VLP Master and is kept ready
to take over the VLP Master’s tasks.
In the smallest model ETERNUS CS50 this is the only ISP and combines
the attributes of the ICP, IDP and VLP. For the TVC the local disks are
configured to form a RAID10 instead of an external RAID system.

LD
A logical drive is a virtual, non-physical drive which presents the host applications the
interface of a real drive which is emulated by a program. Two types of emulation programs are distinguished in ETERNUS CS HE; these are referred to as VTD (Virtual
Tape Device) and 3490 Emu (or Emu for short).
VTD emulations are used when the hosts are connected via FC SCSI. The emulated
device types are EXABYTE/Mammoth2, FSC/CentricStor, IBM/IBM 3590E1A, BM/LTO
Ultrium 2 and STK/9840B.
3490 emulations are used when the hosts are connected via ESCON or FICON. The
emulated device types are IBM 3490-E and Fujitsu F6473K.
Depending on the authorization information (license keys) installed, a total of up to 128
LDs can be operated per ICP. However, more than 64 LDs per ICP are only permitted
for ICPs whose host channel connections are all of the type FC SCSI.
Local Unit ➟ LUN
Location
A location is a combination of ETERNUS CS HE components which are physically close
to each other. In other words these components are either accommodated in the same
rack or in multiple racks which are set up immediately next to each other.
The models ETERNUS CS50, CS500 and CS1000 form a single location (SingleLocation System).
In ETERNUS CS1500 or higher up to 3 locations are possible. These are assigned the
standard names A, B, and C (Multi-Location System).
If the locations are at geographically separate sites, this is called a Multi-Site System.
Otherwise the term Single-Site System is used.

Glossary
LUN
A Logical Unit Number (LUN) was originally, and still is, used to address subunits of a
SCSI target, for example individual drives of a tape library, in the event of I/O requests.
LUN masking refers to the masking of LUNs of a SCSI target in such a way that particular
users can only access particular devices. In ETERNUS CS HE this functionality is
implemented by means of LUN mapping, in which the original LUN range specified by a
particular host is mapped onto an equally large map LUN range on the available devices
(logical devices) in such a way that the devices represented by the mapped LUNs are
available exclusively to this host.
In the storage world the term LUN is used to refer to the subdivision of a RAID system
into logical disks and has been extended to include logical unit, as a result of which LUN
refers to a virtual disk as seen from outside of the RAID system.
LUN Masking ➟ LUN
LUN Mapping ➟ LUN
LV
A logical volume (LV) is a file which is stored temporarily in a tape filesystem of the Tape
Volume Cache (TVC) and stored permanently in a physical volume (PV). The standard
size in an LVG is 900 MB, but this can be selected in discrete steps: 2, 5, 10, 20, 50,
100 oder 200 GB.
Depending on the model, up to 1.5 million LVs can be defined in an ETERNUS CS HE
system, the name of each (VSN) being unique in the system.
LVG
Group of logical volumes for which the same rules apply.
LV stub
The part of a logical volume which (regardless of the Cache Policy) remains resident in
the TVC is identified with LV stub or, in an unambiguous context, with stub. It is 128 KB
in size and contains all the metainformation and the first data blocks of the logical
volume.

Manager Node
When the CAFS Cluster is configured, the CAFS Nodes which can be considered as
Manager Nodes for the roles of Configuration Manager and Filesystem Manager are
specified. The Manager which is then active during CAFS Cluster operation is then
determined automatically.
In then models ETERNUS CS500 and CS1000 both ISPs (IUP0 and IUP1), and in the
models ETERNUS CS1500 or higher both VLP ISPs (VLP0 and VLP1) are configured
as Manager Nodes. In the model ETERNUS CS50 the single ISP is naturally also a
Manager Node.
Message Manager ➟ MSGMGR
Migration
Files which have not yet been premigrated are saved on tape. Their file contest on disk
is released except for a stub. Files which have been premigrated are released except
for a stub.
MSGMGR
Exists once in ETERNUS CS HE. Filters and saves the ISPs’ system messages and
implements predefined measures (e.g. service call, sends SMS, etc.). The MSGMGR
is also responsible for forwarding the system messages to the user interface.

NAS
Network Attached Storage (NAS) is storage which is made available by an autonomous
computer, also referred to as a filer, in a LAN via the NFS (Network File System) or
SMBP (Server Message Block Protocol). The latter is also referred to as CIFS (Common
Internet File System), LAN Manager Protocol or NetBIOS Protocol and is implemented
in Linux by means of the free software Samba.
In ETERNUS CS HE the role of a filer is performed by the ICP, ICP_IDP (IUP) or VTC.
NAS ICP
Der NAS ICP bildet innerhalb des ETERNUS-CS-HE-Clusters die Schnittstelle zum
Kunden-LAN für Zugriffe auf Netzwerkdateisysteme, die via NFS und/oder CIFS freigegeben wurden. Im Gegensatz zu den ICPs der VTL benötigt ein NAS-ICP mindestens
ein externes Netzwerkinterface.
Ein NAS-ICP ist mit 4 LAN-Ports ausgerüstet. Für den Anschluss an den NAS-Cache
besitzt der NAS ICP zwei interne FC-Ports. Die zentrale Aufgabe des NAS-ICP ist die
Bereitstellung von Filesystemen für Applikationen, die auf den Hosts des Kunden-LAN
laufen. Die Filesysteme können in ein hierarchisches Speichermanagement integriert
sein.
NAS IDP
Auf dem NAS-IDP laufen die Dienste des hierarchischen Speichermanagements. Diese
benötigen den direkten Zugriff auf die Ressourcen des Hintergrundspeichers.
Der NAS IDP ist zuständig für die Kommunikation mit den Tape Libraries und Bandlaufwerken, um Kopien von Dateien aus NAS-Filesystemen auf Bandvolumes zu speichern
bzw. von dort abzurufen. Er ist mit den dafür erforderlichen SAN- und/oder LAN-Schnitstellen ausgestattet. Die Kommunikation mit den anderen Rechnern des ETERNUSCS-HE-Clusters erfolgt über eine redundante LAN-Verbindung.
NAS Filesystem
A NAS Filesystem (NASFS) is a filesystem in the CAFS, in which ETERNUS CS HE provides shares for storing data via NAS interfaces (NFS, CIFS).
native tape format
The native tape format of a PV corresponds to the original format of the LV as transferred
from the host applications to ETERNUS CS HE; it consequently contains no metainformation. The assignment between LV and PV is 1:1. The VSNs of the LV and assigned
PV are identical.
Native tape format is mandatory for a PV which is to be saved at a cascading destination. But native tape format is also permitted for backup to physical backend devices.
Native tape format is configured by assigning the PVG attribute Type the value NATIVE.

Network Shared Disk ➟ NSD
NFS ➟ NAS
NSD
The term Network Shared Disk (NSD) refers to a disk which has been assigned a name
that is unique within the CAFS Cluster. The disk can be: a physical disk, a partition of a
physical disk, a logical disk (LUN) or a partition of a logical disk. Normally all ISPs are
connected to an NSD via the SAN. When this direct access to an NSD is interrupted,
access must take place over the LAN via the primary or secondary NSD server which
is assigned to this NSD.
The NSD name begins with rd if the NSD is contained in an external RAID system,
otherwise it begins with the name of the ISP on whose local disks it resides. The
following naming schema is used:
<NSD-name>
rd<xx>L<yyyy>[p<z>] or <ISP-name>L<yyyy>[p<z>]
<xx>
RAID number, 2-digit, decimal
<ISP-name>
ISP name
<yyyy>
LUN, 4-digit, hexadecimal
<z>
Partition number, 1- or 2-digit, decimal
An NSD which is assigned for use by a CAFS Filesystem has the NSD Usage attribute,
which has one of the following values:
dataAndMetadata
The NSD contains both metadata and user data.
dataOnly
The NSD contains only user data and no metadata.
metadataOnly
The NSD contains only metadata and no user data.
descOnly
The NSD contains no user data and no metadata, but a socalled Filesystem Descriptor.
The NSD is automatically assigned the appropriate value for the ETERNUS CS HE
model and for the location concerned during the GUI configuration of the CAFS
Filesystems. This value can only be set explicitly in Expert mode.
The value of the NSD Failure Group attribute is also set automatically and can only be
modified when the GUI is in Expert mode. NSDs which can all fail simultaneously as the
result of a particular error event, for example all NSDs at one location, are assigned to
the same NSD Failure Group. If, for example, the replication factor 2 is set for the user
data and/or metadata of a filesystem, CAFS attempts to store the two copies in NDSs
in different NSD Failure Groups so that the user data and/or metadata remains available
when only one NSD Failure Group crashes.
NSD Failure Group ➟ NSD

Glossary
NSD Name ➟ NSD
NSD Server
An NSD Server is a CAFS Node which must be connected directly to the NSD which it
accesses on behalf of other CAFS Nodes. A primary and a secondary NSD Server can
be configured for each NSD. A CAFS Node can perform the role of the NSD Server for
multiple NSDs. It can simultaneously be the primary NSD Server for some NSDs and
the secondary NSD Server for others. If a CAFS Node has either no or only restricted
access to an NSD (e.g. failure of either both or one of the redundant SAN connections),
it communicates with the associated primary NSD Server, and if this does not respond,
with the secondary NSD Server.
As in ETERNUS CS HE all ISPs (with the exception of the TBP) are connected to all
NSDs via the internal SAN and via the internal LAN, and with each other also via the
internal LAN, each one of them satisfies the requirements to be the NSD Server for
each NSD. For the models ETERNUS CS500 and CS1000, IUP0 is configured as the
primary NSD Server and IUP1 as the secondary NSD Server for all NSDs. In the model
ETERNUS CS1500 or higher VLP0, which belongs to Location A, is the primary NSD
Server for all NSDs of Location A and the secondary NSD Server for all NSDs of
Location B, while VLP1, which belongs to Location B, performs the complementary
NSD Server roles.

519
Glossary
PV
A physical volume (PV) is a data storage which is managed by the PLM (Physical Library Manager). The following cases must be distinguished here:
1. The PV is a real magnetic tape cartridge on which generally multiple logical volumes (LVs) are stored together with additional metainformation in a CS-internal tape
format.
2. The PV is a real magnetic tape cartridge on which precisely one logical volume is
stored in native tape format (➟ native tape format). This format corresponds to the
original format of the LV when it is transferred from the host applications to
ETERNUS CS HE; it consequently contains no metainformation. PVs of this type
occur particularly when the ETERNUS CS HE system is functioning as a cascading
source, but they can also occur independently of the existence of cascaded
ETERNUS CS HE systems.
3. The PV is a virtual magnetic tape cartridge on which precisely one logical volume
is stored in native tape format. In this case the ETERNUS CS HE system functions
as a cascading source.
The VSN of a PV is defined when the PV is added to a PVG. The other configurable
attributes of a PV correspond to the attributes of the assigned PVG. The Type attribute
has the value NATIVE for PVs in native tape format, and in all other cases the value
STACKED.

Reconciliation
This term refers to an action of the HSM Component for comparing the contents of a
filesystem with the managed metadata. For example, as a result of the reconciliation the
metadata for deleted files is invalidated on the BSM.
RAID (Redundant Array of Independent Disks)
A RAID System consists of at least a RAID controller and a disk array. A RAID controller
organizes the data on the disk array in such a manner that a disk error will not result in
any data being lost and that higher read and write speeds can be achieved than with a
single disk. Loss of data is prevented by redundant storage of the data on different
disks, i.e. by mirroring. Higher read and write speeds are achieved by striping, i.e. by
splitting the data into stripes which can be accessed in parallel. Precisely how these two
basic functions work on their own and in combination is specified by the RAID Level.
In ETERNUS CS HE the two mirrored system disks of an ISP form a RAID system of
RAID Level 1 (simple mirroring). The 6 internal disks which are used in the model
ETERNUS CS50 for the TVC, on the other hand, are configured as a real RAID system
of RAID Level 10. Here striping takes place using disks which are mirrored in pairs
(RAID 0 via multiple RAID 1).
In the models ETERNUS CS500 or higher external RAID systems which are connected
to the ISPs via the internal SAN and the internal LAN are used for the TVC. A RAID
system of this type consists of so-called shelves. A shelf contains up to 15 disks and is
equipped with redundant power supply modules and fans. The shelf which is also
equipped with 2 RAID controllers is called a RAID basic unit. A shelf without RAID
controllers is called a RAID extension. An external RAID system which is used in the
models ETERNUS CS500 or higher consists of one RAID basic unit and up to 7 RAID
extensions, and RAID Level 5 is configured for each of these RAID systems.
RAID System
A RAID (Redundant Array of Independent Disks) system consists of one or two RAID
controllers and multiple physical hard disks. These are organized as a logical disk drive
which permits a greater storage capacity, greater data security and/or greater
throughput than a single physical disk drive.
The TVC of an ETERNUS CS HE system uses one to up to eight RAID systems.
Recall
The file content on disk is recovered from the tape copy.
Redundant Array of Independent Disks ➟ RAID System

Glossary
Reorganisation
Depending on the configuration paramters, the logical volumes (LVs) saved on the
physical volumes (PVs) are automatically copied onto other physical volumes (PVs) of
the same physical volume group (PVG). This is done for the following reasons:
–
–
–
Effective use of the physical volumes (PVs) available
Prevention of physical and chemical aging processes
Faulty or inaacessible physical volumes (PVs)
This procedure is called Reorganisation. Reorganisation of an individual physical disk
(PVs) can also be initiated by the administration.
Replication Factor
The Replication Factor specifies the number of copies which the CAFS makes of the
user data, metadata and the Filesystem Descriptor of a CAFS Filesystem in order to
enhance availability in the event of a malfunction. Replication Factor 1 means no
replication; the data is only backed up once. With Replication Factor 2 the data is replicated and stored on NSDs in different NSD Failure Groups. A separate Replication Factor
can be assigned to the user data, the metadata and the Filesystem Descriptor.
During the GUI configuration of the CAFS Filesystems the Replication Factor is
assigned automatically in accordance with the ETERNUS CS HE model and the configuration of the locations. The Replication Factor for user data, metadata and the
Filesystem Descriptor of a CAFS Filesystem can only be set in the Expert mode of the
graphical user interface (GUI).
S
SAN
The entire data flow between all ETERNUS CS HE components (ISPs and external
RAID Systems) is handled via an internal Starage Area Network (SAN) which must be
configured redundantly for the models ETERNUS CS1500 or higher. It is implemented
by one FC switch with high-performance capability, or, when redundancy is provided in
single-site systems, by two of these, or by at least four of these in multi-site systems.
Two FC technologies are available: Multi Mode and Single Mode. In Multi Mode the
devices which are connected via 4 Gbit Fibre Channel can be located up to 150 m from
each other; in Single Mode the distance can be as much as 30 km.
Scope
A scope is understood as the scope of variables, namely program or file sections in
which the variables are usable and visible.
Example: The ETERNUS CS HE configuration file vtls_add.conf contains scopes for
special configuration settings which cannot be made via the graphical user interface.

Server Management
The functions for monitoring the physical statuses of the hardware components of an
ETERNUS CS HE ISP, e.g. temperature, power, are referred to collectively by the term
Server Management. Since ETERNUS CS HE V4.0A these functions have been implemented using the corresponding software modules of PRIMERGY ServerView Suite.
One major task of Server Management is to analyze the System Event Log (SEL), an
NVRAM (non volatile random access memory) in which the BMC (Baseboard
Management Controller) and BIOS log hardware incidents in accordance with the
industry standard IPMI (Intelligent Platform Management Interface).

Service Pack
A service pack consists of all the ETERNUS CS HE software which implements the
functions and patches released in an ETERNUS CS HE version at a particular time.
This includes the following data carriers:
–
–
a service pack DVD
a patch CD if patches have been released.
The data carriers can be used both for initial installation and for update installation.
A service pack is identified unambiguously by the combination of the number of the
service pack DVD and the number of the patch CD. When a new service pack DVD is
produced, i.e. its number is incremented by 1, the software stored on it incorporates all
the corrections of the patches in the last service pack.

Glossary
TFG
A Tape Filesystem Group (TFG) can consist of one or more tape filesystems. The ETERNUS-CS administrator generates a TFG by selecting the tape filesystems which are to
belong to this TFG and by assigning the TFG a name. Assignment of a TFS to the
specified TFG does not take effect immediately after this selection has been made, but
only after further configuration steps (see below).
Each tape filesystem belongs to precisely one TFG. If a tape filesystem is not explicitly
assigned to a named TFG, it automatically belongs to TFG FLOATING, which exists implicitly and cannot be generated or deleted.
The assignment of an LVG to a named TFG or to TFG FLOATING defines that the LVs
of the LVG are distributed evenly over the various tape filesystems of just this TFG. The
corresponding definition of a TFG thus enables the tape filesystems of this TFG to be
used exclusively by the LVs of the assigned LVGs. As long as no LVG is assigned to a
specified TFG or as soon as no LVG is assigned to a specified TFG, the tape filesystems which are explicitly assigned to this TFG do not belong to the specified TFG but
to the FLOATING TFG.
If a TFS is removed from a TFG, the LVs stored in the TFS are moved to the remaining
tape filesystems of the TFG.
TFS
Since ETERNUS CS HE V4.0A a Tape Filesystem (TFS) is a filesystem of the type gpfs
(CAFS) in which the logical volumes (LVs) are stored temporarily. The tape filesystems
as a whole constitute the Tape Volume Cache (TVC). In ETERNUS CS HE the tape
filesystems are tied to a permanent naming schema: /cache/nnn, where nn stands for
a number between 100 and 899. When the Cache Mirroring Feature (CMF) is used, each
tape filesystem is mirrored. The tape filesystems are configured within the ETERNUS
CS HE configuration by means of GXCC. The storage space available for a TFS is
provided by NSDs being assigned exclusively to this TFS.

Like an ICP_IDP it combines the attributes of an ICP, IDP and VLP. In contrast to the
ICP_IDP it is equipped with additional boards. These boards and an internal RAID
controller are used to configure an internal RAID system which is used for the TVC.
The predefined host name for this ISP type is VTC.

WORM
WORM is the abbreviation for Write Once and Read Multiple (times). In other words: data
which is written to a WORM tape cannot be overwritten or modified and can be deleted
only by means of demagnetization. This permits, for example, audit-standard storage of
data during its entire archiving period.
