For your own safety
In the interest of your own safety and perfect performance of your
new product and computer system please note the following:
- Computer components and disk drives are sensitive to static
charge. Take precautions to divert any electrostatic charge from
your person before and while handling the components with your
hands or any tools.
- Before removing Controllers or Power Supplies ensure that the
system is powered down and disconnected from the main
electrical socket.
- Ensure correct lifting methods are used when handling the

Configuration of the SATABoy is conducted by NexScan, Nexsan’s
unique configuration tool. NexScan allows the SATABoy to be
configured by either the built in web server or via the on board
RS232 serial port. Both methods are not hardware, software or java
runtime specific. The web interface uses standard HTML and is
compatible with all mainstream browsers (Internet Explorer,
Netscape, Opera, Mozilla etc).
All main components of the SATABoy are pluggable; these include
PSUs (Power Supply Units), RAID controller(s) and disks.
Owing to the SATABoy’s huge data capacity, low cost and amazing
performance it is ideal for many applications such as disk-to-disk
backup, streaming video and audio, secondary storage and fixed
content archiving.

Getting Started
This part of the manual is designed to enable you (the user) to
configure and start using your SATABoy quickly and safely. Please
carefully read and review all the information in this section before
installing the product.
[03.01]
Before you begin
Ensure that the ambient temperature of the installation site for the
SATABoy does not exceed 30°c. If the temperature of the
installation site is not automatically regulated, then ensure that
seasonal climate changes will not result in the maximum
temperature being exceeded. The product’s ambient temperature
requirement remains the same when multiple units are present.
Ensure full airflow is possible. Do not obstruct the front or rear of
the product.
Do not lift a populated SATABoy chassis alone, remove all
pluggable components first then ask a colleague to assist you.
If installing the SATABoy into a rack mount cabinet you are advised
to remove the power supplies and disks before doing so. This will
make the unit much lighter to lift. When installing into a rack
mount cabinet take extra care not to trap fingers and clothing
during the installation. Please follow the Rack Mount Instructions
included with the Unit (or see the relevant section of this manual).
If the SATABoy is being installed into a rack, please ensure that the
rack is correctly grounded.
The user must ensure that the main power drawn by the
equipment does not overload the available electrical supply in the
rack. When connecting the equipment to the electrical supply,
please consult the rating details of the SATABoy.

A disposable ESD strap is supplied with the unit as protection
against Electrostatic Discharge. This strap should be worn at all
times and properly tied to ground while handling your Nexsan
systems. Ensure that your environment has sufficient ESD
safeguards to protect against latent failures. Failure to protect
against ESD may result in critical losses.
[04.0]
Single and Dual Controller
Configurations
The SATABoy supports both single controller and dual controller
configurations. Dual controller systems support controller
failover, so that, should either controller fail host access to disk
data will continue. Depending on your requirements, both
controllers can be configured to be active for improved
performance and data availability. This is referred to as being an
active-active or AA configuration.
This manual will focus on a single controller installation. Notes will
be added for any differences concerning dual controller activeactive configurations.

Setting up the network
The SATABoy controller ships with a default IP address depending
on the slot it is inserted to.
Slot
0 (top)
1 (bottom)
Default IP Address
10.11.12.13
10.11.12.14
It is likely that this address may not be accessible from the IP
configuration of your network. To change the IP address there are
two main methods;
1) Add a route to access the desired IP address.
2) Use the serial port to change the IP address to something suitable.
Both methods are acceptable.
[11.01]
Add a route to access the desired IP address
To add a route to access the desired IP address you must have access
to the CLI (command line interface) or a shell window / terminal.
Type the following line, according to your OS to add the route
Windows: route add 10.11.12.13 mask 255.255.255.255
<Workstation IP number>
Linux: /sbin/route add 10.11.12.13/32 gw <Workstation IP number>
Solaris: route add 10.11.12.13 mask 255.255.255.255
<Workstation IP number>
Replace <Workstation IP number> with the IP address of the
workstation you are using.
NOTE: To add a route for the controller in Slot 1, you will also need
to change the route to 10.11.12.14
27
[w] www.nexsan.com
Once the routing has been established, you will be able to access the
SATABoy’s web interface using a standard browser. It is important to
complete the network configuration of the SATABoy. To do this you
must type the IP address of the SATABoy into your Internet Browser
(i.e. Microsoft Internet Explorer or Netscape Communicator).
When you hit return or the GO button the browser should load the
SATABoy’s login page. You will need to click the login button to
continue; by default there is no username or password.
Once the main page is loaded, click on the ‘Network Configuration”
button on the left hand side.
28
A new page will load in the main frame of the GUI. All the pages in
the main frame (except the home frame) have multiple tabs at the
top of the page, these are used to access other related pages.
How to set IP address – decides whether to use DHCP (Dynamic
Host Configuration Protocol) or a manually set IP address. Use the
radio buttons to select the desired value. If you choose DHCP you
will not need to choose any further values. It is recommended to
have your DHCP server reserve a static IP for your SATABoy.
IP address – assuming you have chosen to set up the network
manually enter a free IP address into the field. The IP address that
you already have may be fine.
Subnet mask – set the subnet mask that fits the class of your
network. In most cases 255.255.255.0 is acceptable. Type the new
subnet mask into the text box.
Gateway – type the IP address of your Internet gateway into
this text box.
Primary/Secondary DNS – type the IP address of both your Primary
and Secondary DNS into the respective text boxes.
When you have updated all these settings click the ‘Save
Configuration’ button.
NOTE: You will need to restart the system before these changes
take effect.

Use the serial port to change the IP address to something suitable.
You will need to use the serial port of your computer, sometimes
known as a COM port, with the supplied DB9 cable. This cable is
known as a null modem cable, unlike a straight-through cable a
null modem cable has lines 2 and 3 crossed.
The below instructions are for using ‘Hyper Terminal’. Alternatively,
you can use any terminal emulation program.
First, ensure that the serial cable is connected to the SATABoy and
to an available serial port on your computer.

When the controller reboots you are advised to use the web
interface to continue the configuration of the system.
To access the GUI, type the newly designated IP address of the
SATABoy into your web browser.
When you press return or the GO button, the browser will load the
SATABoy’s login page. You will need to click the login button to
continue; by default this will not require a user name or password.
Now the main page is loaded, click the ‘Network Configuration”
button on the left hand side of the main page.
35
[w] www.nexsan.com
Before loading a new web page, the web server may ask you to
provide a user name and password in order to continue (depending
on configuration); the default username and password are as follows:
User name = ‘ADMIN’ (in uppercase without the quotation marks)
Password = ‘PASSWORD’ (in uppercase without the quotation marks).
Once the user name and password are accepted a new page will
load in the main frame of the GUI. All the pages in the main frame
(except the home – system status page) have multiple tabs at the
top of the page, these are used to access other related pages. In

Setup Fibre Channel Interface
In order to ensure correct operation of the Fibre Channel interface
you should use the web GUI to review and / or alter the Fibre
Channel settings.
From the home page select the ‘Controller Admin.’ on the left side
39
[w] www.nexsan.com
When the main frame reloads, click ‘Fibre’ from the row of tabs at
the top of the page.
The Fibre page allows the configuration of both Fibre Ports on
the current controller. Use the drop down menus to configure
the settings.
Topology – allows you to select between ‘Point to Point’, ‘Loop’
or ‘Auto’ topologies. The loop topology should be used when
connecting to other devices using a switch. ‘Point to Point’ is
normally used when connecting directly to an initiator or switch.
The ‘Auto’ mode will try to negotiate what topology to use, this
works by trying to connect to a loop, failing this it will try to
connect using ‘Point to Point’ mode. Auto may not always work,
especially if the device(s) at the other end are also using
automatic configuration.
Loop ID – selects the ID of this port. Use the drop down menu to
select an address between 0 and 126. Auto may also be selected to
find an address that is not already occupied. Loop ID does not need
to be set if you are running in ‘Point to Point’ mode.
Link Speed – denotes the speed of the connection. The SATABoy is
capable of running at either 1Gbit (One Gigabit per second) or 2Gbit
(Two Gigabits per second). You should set this speed depending on
your other Fibre Channel equipment. It is also possible to use Auto
mode to attempt negotiation of the correct speed.
40
Frame Size – chooses the frame size to be used. The frame size
relates to the data payload of each packet. Typically the larger the
payload the more data can be transmitted. The available frame
sizes are 512, 1024, 2048 and 2112.
After both interfaces have been configured click the ‘Save new
configuration’.
NOTE: The settings will be applied at the next restart of the system.

Quick Start
Quick Start is a quick and easy way to set up the SATABoy.
This will create one RAID 5 array per controller and either one or
two volumes, depending on the setting selected. If you are using
many high capacity disks it may be the case that you end up with
more LUNs than expected, as the maximum LUN size is 2.2TB. If
you require LUNs to be over 2.2TB please contact technical support.
All volumes are mapped to both host ports. The Fibre Channel
interfaces are set to AUTO mode.
The default shipping configuration for the SATABoy is Quick Start
with one volume.
If your system has no arrays present, Quick Start is a good way to
get started.
From the GUI home page click on ‘Quick Start’ from the left frame.
The main frame will then display the default Quick Start
configuration, 1 volume config, this can be changed by clicking the
tabs on the top left of the main frame.
42
The available options are, ‘1 volume configuration’ and ‘2 volume
configuration’.
Select the configuration that is most applicable to you. If neither fit
what you want to achieve you should consult the ‘Creating Custom
RAID arrays and Partitions’ section of the manual.
The main frame will then display the options and settings that will
be changed in order to complete the Quick Start process.
43
[w] www.nexsan.com
The Quick Start process will automatically change any settings that
are not already configured correctly. There is no need to change
anything before starting the process.
To continue you must click in the confirm checkbox and then click
the ‘Quick Start’ button.
A final warning will appear to ensure that you are aware that any
current data will be destroyed.
Again, click the tick box and click ‘Confirm Quick Start Configure’
to continue or click the ‘CANCEL Quick Start’ button to cancel.
The Quick Start operation will take several hours to construct the array
data. You can check on the progress of this in the progress page.
From the home page, click on ‘RAID information’ in the left frame.
44
Then click on ‘Progress’ tab from the top of the main page.
The progress page displays the progress of any controller based
utility on any of the configured arrays.
The above example shows 1 array being constructed. When the
progress bar reaches 100% the array is ready to be used.
This concludes the ‘Getting Started’ section of the manual.

Creating Custom RAID
arrays and Partitions
Although the default setup may be acceptable for many customers,
it is possible to easily create custom RAID arrays and volumes of
different types and sizes.
In order to create a RAID array you must have free or unused disks.
Free disks are disks that do not belong to a RAID array and are not
configured as hot spares. If there are no free disks, then disks must
be made available.
Drives can be made available by deleting a configured RAID array or
by deleting hot spares. Hot spares are easily deleted but RAID arrays
must contain no volumes before they can be deleted. In order to
delete a RAID array, all the volumes on the array must be deleted.

Creating RAID Arrays
From the left hand menu on the home page of the GUI, click on the
‘Configure RAID’ button.
In the main frame click on the ‘Add Array’ tab from the top of
the page.
Select the available drives (yellow) by checking the tick boxes. You
can configure between 2 and 14 drives into a single RAID array.
At the top of the page you can also select the following features
Array Name – This is a friendly name that will help you identify the
new RAID array, set this to something that describes the use of the
array such as ‘customer database’.
50
Select RAID level – allows you to choose the RAID level that best suits
your application. Use the drop down to select the correct RAID level.
Select Stripe size – use the drop down menu to select the desired
stripe size for your array.
Select array owner – this option is only shown in active-active
mode, use this to select which controller the array will belong to.
Once all the settings and disks have been selected click the ‘Create
RAID Set’ button to begin RAID array construction.
The construction of an array takes several hours. You can check on
the progress of this in the progress page. From the home page,

[13.04]
Renaming an Array
The Rename array feature is used to change the user defined
friendly name of each configured array.
Click the ‘Configure RAID’ button on the left side of the GUI.
Then click the ‘Rename Array’ tab from the top of the main page.
52
The ‘Rename Array’ page will appear in the main section of the
web GUI.
To rename an array simply enter the new name of the array in
relevant text box and click the ‘Save Settings’ button.
[13.05]
Add Spare
This page allows a hot spare to be added. There are two types of
hot spare disks, a pool spare and a dedicated spare.
Add a pool (floating) hot spare disk – this type of spare disk
will be used by any existing parity array that becomes degraded
providing the capacity of the disk is large enough to be used by
the degraded array.
NOTE: If the disk is smaller than the smallest disk in an array it will
not be used for rebuilding.
53
[w] www.nexsan.com
Add a hot spare disk dedicated to an array – this type of spare is
assigned to a specific array, if any other array becomes degraded this
disk will not be used for rebuilding, this disk will only be used to
rebuild onto by the array it is assigned to. Note that when adding this
type of spare the array it is to be assigned to must be selected.
NOTE: Under default configuration when a new disk is inserted the
disk will automatically be configured as a pool spare.
[13.06]
Delete spare
Use this page to change the usage of a disk from a spare to
unused. This is required if you want to use disks shown as spares as
part of a new RAID array. More than one disk can be selected,
although it is advised that one hot spare is left available to rebuild
onto should an array member disk fail resulting in a degraded
array. Leaving an array in a critical state is not advisable. Your data
is more vulnerable and data could be lost if another disk fails
(depending on RAID level).
54
[13.07]
Array Owner
When operating in active-active mode you will have this
additional page shown. This page allows the owner controller of
arrays to be changed. The controller that ‘owns’ an array will be
the controller that processes host IO for the volume(s). Should a
controller fail, the arrays owned by the failed controller will
temporally be moved over to the surviving controller. When the
failed controller is replaced or restarted the arrays will move back
to the configured owner controller.
NOTE: The current firmware does not support ‘failback’ or hot
plugging. When a controller fails the only way to bring it back
online is to restart the system (either power cycle or select reboot
controller(s) from the web GUI).
[13.08]
Configuring Volumes
All the configuration of volumes is done within the ‘Configure
Volumes’ section of the GUI. The different configuration functions
are accessed by the tabs at the top of the screen.
55
[w] www.nexsan.com
[13.09]
Creating Volumes
The Configure Volumes section of the GUI allows the user to create,
expand, rename, delete, LUN map and LUN mask volumes.
In order to use the capacity in an array, a volume must be created
first. By default, one full size volume is created for each array
created (unless the 2.2TB Limit is breached). However, this volume
can be deleted and multiple smaller ones created instead. Volumes
can also be mapped to either one or both of the host ports of the
system. This allows two completely independent computers to
access different volumes on the same array.
Volumes have certain limitations. The best way to understand how
the volumes work is to visualise an empty array as an empty block.
If the array is empty the first volume you create will start at the
beginning of the array (unless you specify to leave free space there)
The above shows a dark grey section that represents a created
volume, roughly 20% of the entire capacity of the array. You can
see that it begins at the beginning of the array. A second volume
can be added after the first.
56
The newly created volume is shown above in light grey. The new
volume backs directly on to the previous volume.
It is possible to expand volumes if there is free space directly at the
end of the volume. Because of this the blue volume cannot be
expanded, but the yellow can.
The light grey volume has been expanded. If another volume is
created directly on the end of it further expansion is no longer
possible. Because of this there is feature when creating a new volume
to ‘reserve’ space for future expansion of the previous volume.
Above a third volume has been added (in mid grey) that reserves
space for future expansion of the yellow volume. The reserved space
can only be used by the volume that ends before the free space.
57
[w] www.nexsan.com
The above picture shows that the light grey volume has now been
expanded into the reserved free space.
It is possible to delete a volume and reuse the space to create
new volumes.
The above picture shows that the dark grey and mid grey volumes
have been deleted. It is now possible to create new volumes in the
available space. However it is not possible to create a single volume
that spreads over two or more areas of free space. The largest
volume size that can be created is equal to largest single area of
free space. The RAID controller will, by default, create a new
volume at the first area of free space. If this is not possible, for
example the first area of free space is not large enough for the
desired size, then the controller will use the next free space area
that is large enough.
To create a new volume, click on the ‘Add Volume’ tab at the top of
the ‘Configure Volumes’ page.
58
The ‘Add Volume’ page will then load in the main frame.
To create a volume, select the array by clicking the radio button
next to it (located at the top of the page). All the configured arrays
will be displayed. No arrays are selected by default.
Once the array has been selected you may want to view how much
space is available on the array.
When you know what space is available use the following sections
to define the volume’s parameters.
Enter the name for the new volume – defines the friendly name
of the volume.
Enter the size of the new volume in MB – defines the size of the
new volume in Megabytes or the currently selected units.
Reserve an optional free space area at beginning of the new
volume for future expansion of a previous volume – defines
how much, if any, free space should be reserved for expansion of
the previous volume.
Select logical unit number (LUN) for new volume on host 0/1 –
defines the LUN value of this volume on host ports 0 and 1.
59
[w] www.nexsan.com
Once you have defined the relevant parameters click the ‘Create
Volume’ button. The volume will be created and mapped instantly.
[13.10]
Active-active differences
When adding or creating a new volume in active-active mode you
first need to select an array. Below is an example.
Arrays with no free space will not be available. Click the radio
button next to the array you wish to add a new volume to. Then
click the ‘Next>>’ button, once this has been done you will see the
‘Create New Volume’ page.
[13.11]
Expand Volume
The ‘Expand Volume’ tool allows expansion of volumes. Volume(s)
can only be expanded if there is free space directly after it.
Click the ‘Expand Volume’ tab to at the top of the ‘Configure
Volumes’ page.
60
This will change the main page and display the ‘Expand
Volume’ settings.
Each volume with details of free space is displayed on this page.
To expand a volume, simply type the new size into the text box.
Then click the ‘Expand Volume’ button to expand. Volumes with no
free space available will not have the ‘Expand Volume’ text box or
button displayed.
[13.12]
Rename Volume
Volumes can have their assigned friendly names changed by using
the ‘Rename Volume’ page.
Click the ‘Rename Volume’ from the top of the page.
61
[w] www.nexsan.com
This will display the ‘Rename Volume’ page.
To change the friendly name of a volume, type the new name into
the respective text box. You can change the name of more than one
volume at a time. When you have made the changes, click the ‘Save
Settings’ button to confirm.
[13.13]
Map Volume
In order to be available to a host system, each volume must be
mapped to a LUN on at least one host port. If the volume was not
mapped when created or you want to change the mapping then
use this page.
Click the ‘Map Volume’ button at the top of the page.
This will load the ‘Map Volume’ page into the main section of
the web GUI.
62
Use the drop down menus for each volume to select the LUN for each
host port. A volume can be assigned to a LUN with a value between 0
and 31. Selecting UNMAPPED will make the corresponding volume
unavailable to all attached host systems on the corresponding host
port. If there are identical LUNs on a host port at least one will be
automatically set to UNMAPPED when ‘Save Settings’ is clicked. This is
done in order to allow the configuration to succeed. It is important
that each LUN is unique per host port.
Press the ‘Save settings’ button to confirm changes.
NOTE: Changes are made immediately, so changing the LUN of a
volume in use could cause your Operating System to crash or lose
communication with the volume.
[13.14]
When in ‘2 port active-active’ mode you will only be able to
change the LUN of volumes being presented on an active port.
The active port on which a volume will be presented is
determined by which controller the array and volumes are owned
by. Changing the owner of an array will change the port on
which the volumes will be presented.

Configuring Fibre Channel
and LUN Masking
This section of the manual is designed to give a better
understanding of the Fibre Channel interface features and the
setup parameters.
[14.01]
Fibre Channel Topologies
The SATABoy is capable of supporting the two most commonly
recognised Fibre Channel topologies; point to point and loop.
[14.02]
Loop Topology
The loop topology can be used to directly connect to a HBA (Host
Bus Adapter) running in loop mode, but point to point is actually
more efficient at this. Loop is mostly used when connecting the
SATABoy to a hub or loop switch. When using a hub all traffic is
passed through all the nodes in the loop until it reaches the
destination node. The entire bandwidth of the loop is shared by all
the nodes. This significantly reduces performance.
The above diagram shows the two lines from each node going in to
the hub in the centre. Each line represents either the TX (transmit)
or RX (receive) of each nodes cable. The following diagram shows
the route of a packet going from the middle server to the SATABoy.
64
The data travels around the loop until it reaches the destination.
This diagram shows the data being transmitted from the SATABoy
back to the same server.
These diagrams show that loop modes are not particularly efficient.
65
[w] www.nexsan.com
[14.03]
Point to Point Topology
The next series of diagrams show the same scenario as the loop
mode running with a hub but this time using point to point mode
with a fabric switch.
In the above diagram it is not necessary to display the TX and RX as
each node communicates directly with the switch. The logic in the
switch sends data directly from one node to the destination node.
The following diagram shows the same communication as before.
Here you can see that the data does not have to travel via other nodes
and therefore does not affect the performance of the other nodes.
66
[14.04]
LUN Mask
The SATABoy has the ability to define which hosts (initiators) are
allowed to access LUNs. Settings for each LUN are individually
designated. All discovered initiators are listed and they can either
be granted full access or no access.
To use this feature the SATABoy must be connected to a Fabric
Switch and be running in Point to Point mode. It is not possible to
mask LUNs in Loop mode.
To access the ‘LUN Mask’ page click the ‘LUN Mask’ tab at the top
of the ‘Configure Volume’ page.
CAUTION: MAPPING VOLUMES TO MORE THAN ONE HOST CAN
CAUSE DATA CORRUPTION. IF YOU ARE MAPPING TO MORE THAN
ONE HOST ENSURE THAT YOU HAVE THE CORRECT SOFTWARE TO
DO THIS!
The LUN Mask page shows each configured volume. In order to
mask the desired LUN click the radio button and then click the
adjacent ‘Mask LUN’ button.
67
[w] www.nexsan.com
The second page is where the LUN Masking is set. Use the options
on this page to create a mask.
Scan Fabric For Initiator WW Port Names – is a button that scans
the Fibre Channel for any newly added hosts (initiators) that were
not present when the page was loaded.
The second section of the page lists the current initiators in black.
Previously discovered but now missing initiators are shown in grey.
Each Initiator displays it’s ‘Port Address’ and ‘WW Port Name’ The
WW Port Name is the individual address of the initiator (the Fibre
Channel adapter in the host computer). This address can be
identified in the HBA’s BIOS or sometimes there will be a small
sticker on the HBA itself.
68
Each initiator can have access to the volume ‘Enabled’ or ‘Disabled’.
Initiators with volume access enabled will have read and write access
to the volume. Initiators with access disabled will not be able to
access the LUN at all. Select the desired state with the check boxes.
Initiators that have been previously discovered but are no longer
present have the extra option of ‘Remove’. This will delete this
initiator from the list. If it is discovered again it will follow the ‘All
other initiators’ rule.
All other Initiators – is a check box that defines how newly
discovered initiators will be treated. If the box is ticked all new
initiators will gain access to this volume automatically, if the box is
not ticked any new initiator will not be granted access.
When the above options have been defined click the ‘Apply LUN
Mask’ button.

Advanced Network Options
All of the advanced networking options can be found in the
‘Configure Network’ section of the GUI. This can be accessed from
the left hand side of any GUI page.
Each setting can then be accessed from the row of tabs at the top

[15.02]
When operating in active-active mode, the IP address settings for
both controllers will be shown. You only need to access one Web
GUI or IP address as the same configuration and status information
is available from either controller. Should a controller fail you will
have to log onto the web GUI belonging to the surviving controller.
It is important that you configure both controllers correctly and
document both the GUI IP addresses. For email alerts, you must
configure the network settings so that either controller can send
email. This entails configuring the gateway IP address and the DNS
settings on both controllers.
[15.03]
Network Port
Use the Network Port page to alter the speed and duplex mode of
the Network port.
The SATABoy has a 10/100/1000Base T Ethernet port that can be used
in various modes. Use the drop down to select the required mode.
72
Auto negotiate network speed and duplex
Auto negotiate network speed with fixed full duplex
Auto negotiate network speed with fixed half duplex
Fixed to 1Gbit Full Duplex
Fixed to 100Mbit Full Duplex
Fixed to 100Mbit Half Duplex
Fixed to 10Mbit Full Duplex
Fixed to 10Mbit Half Duplex
If the SATABoy is connected to a switch, you may use full duplex.
However half duplex will work fine with hubs and switches, but may
be a little slower. Only use 1Gbit if you are sure you have 1Gbit
networking. If you are not sure about your networking, use ‘Fixed to
10Mbit Half Duplex’ or ‘Auto negotiate network speed and duplex’.
When you have made your decision press the ‘Save Network Port
Setting’ button.
NOTE: You will need to restart the SATABoy for the changes to
take effect.
[15.04]
You will be able to configure the network port settings for both
controllers when operating in active-active mode.
73
[w] www.nexsan.com
[15.05]
E Alert
The SATABoy has the capability of sending an email to a specified
email address in the event of either a warning condition, error
condition or any new event.
SATABoy uses pre-emptive degradation monitoring to discover
possible future problems. Examples are internal temperature higher
than normal, change of the network IP address dictated by a DHCP
server (which means that you will need to use a new network
address to access the Web GUI) and similar events.
Error conditions are comprised of events that significantly reduce the
security of the system. For example, an array member disk failure.
Sender email address – is the senders email address that the
SATABoy uses. You may consider using [email protected] or
[email protected]. To set the sender, type the
address into the text box.
SMTP email address – is the IP address or name of your mail
server. You can only type the name of your mail server (i.e.
mail.mydomain.com) if you have DNS correctly set up either
manually or via DHCP. If DNS has not been configured then you will
have to enter the IP address of your email server. Enter the value
into the supplied text box.
74
Recipient email address – is the email address that the SATABoy
should send email to. This would typically be the address of an
administrator. Type the recipient email address into the text box.
ATA RAID system friendly name – is an easy way to determine the
location of the SATABoy that has sent email. This feature is mainly
useful for users with many systems, this can be set to a name that
relates to the location or use of the unit i.e. Server1 RAID. Type the
desired value into the text box.
When to send – decides under what circumstances an email should
be sent. There are four possible options. ‘Don’t send Email alarms’
will not send any emails, this option is only recommended for users
who do not wish to receive any emails from the unit and will be
able to hear audible alarm should a problem occur. ‘Send Email
alarms for errors only’ will send an email only when errors occur.
This setting is suitable for most users. ‘Send Email alarms for
warnings and errors’ will send email when warnings or errors
occur; this is ideal for expert users. ‘Send Email alarms for all
events’ will send email when any new event is put into the event
log, this option can generate a lot of emails yet is ideal for users
that want to monitor the SATABoy closely. Use the drop down
menu to choose the desired option.
Send automatic status emails – use the pull down menu to
configure how often the SATABoy should send a status email, this
email contains a summary of the system status and lets a user
know the SATABoy is up and running. When set to ‘Disabled’ no
status emails will be sent.
When you have completed the set up click the ‘Save E-Alert
Settings’ button. You may reload this page and use the ‘Send test
email now’ to check that the configuration works.
Send Test Email Now button – use this to test your email settings,
by clicking this button a test email will be generated and sent, if
there is a problem with your email or network configuration the
email will be queued and not sent.
75
[w] www.nexsan.com
Current emailer status – this shows if any emails in the email queue
are waiting to be sent. Emails are queued up in memory to ensure
they are always sent even if your network or email server is busy or
not available. A status of ‘ready’ indicates that all emails have been
sent and the emailer is ready to accept and send new emails.
Clear Email Queue button – this button clears emails from the
email queue, you may need to do this if your network or email
settings were incorrect and emails have been queued up. Bear in
mind that any error or warning emails in the queue will be
permanently lost.
[15.06]
SNMP (Simple Network Management Protocol)
The SATABoy is capable of sending SNMP traps to a SNMP Network
Management Station. The SNMP page is used to configure the
relevant settings in order to achieve this.
76
MIB – At the bottom of this page you can download the MIB
(Management Information Base) for SNMP V1 and V2c
IP address to send SNMP trap to – this should be set to the IP
address of the remote management station that will receive SNMP
traps.
Community string – this must be set to the community string that
your network management station is expecting to receive.
Trap version – select the trap version according to what version of
trap your network management station is capable of receiving.
When to send a SNMP trap – select under what conditions the
SATA system will send a SNMP trap.
To send a test trap enter a test string into ‘test string’ text box,
then click the ‘Send Test SNMP Trap Now’ button.
77
[w] www.nexsan.com
[15.07]
Date & Time
The SATABoy has a real time clock. It is strongly advised that you set
the time and date. This is very important when the system is recording
events to the event log or sending emails and SNMP traps.
You can enter the time and date manually or have the time and
date set by a time server.
Time entered in ‘hh:mm:ss’ format – input the time into this field
in the specified format. Please note that the inputted time will not
tick, the time you type in will be used from the time you click the
‘Save Settings’ button, not from when you typed it.
Date entered in ‘dd/mm/yyyy’ format – input the date in the
specified format.
Time zone relative to GMT (GMT offset) – Use the drop down
menu to select the time zone.
78
To set the Time and Date automatically use the following fields.
Time server IP address to use for auto time and date configure
– allows you to select a predefined time server from the drop down
menu or a custom time server for automatic time and date
configuration. Use the radio buttons to decide which mode to use.
Time server time and date format – is a drop down menu that
allows you to select the format of the data that will be received
from the daytime server. Choose this carefully as many time servers
use different settings. If you are unsure of the time format your
daytime server is sending click ‘Retrieve Daytime Server Data’,
below this button you will see the data the daytime server sent.
Select from the pull down menu the format that matches this data.
Set system time and date by the timer server every 24 hours –
check the tick box if you wish the time and date to be set by the
configured daytime server every 24 hours.
Contact Daytime Server To Auto Configure Time And Date button
– use this to test your daytime server settings or for a ‘one time’
automatic configuration of the date and time from a daytime server.
Retrieve Daytime Server Data – use this button to fetch the time
and date string from your daytime server, this allows you to see
what time and date format your daytime server is using.

Fibre Channel
The Fibre page allows configuration of both Fibre Ports on the current
controller. Use the drop down menus to configure the settings.
85
[w] www.nexsan.com
Topology – allows you to select between ‘Point to Point’, ‘Loop’ or
‘Auto’ topologies. The loop topology should be used when
connecting to other devices using a switch. ‘Point to Point’ is
normally used when connecting directly to an initiator or switch.
The ‘Auto’ mode will try to negotiate what topology to use. First it
will try to connect to a loop. If this fails it will try to connect using
‘Point to Point’ mode. Auto may not always work, especially if the
device(s) at the other end are also using auto.
Loop ID – selects the ID of this port. Use the drop down menu to
select an address between 0 and 126. Auto may also be selected to
find an address that is not already occupied. Loop ID does not need
to be set if you are running in ‘Point to Point’ mode.
Link Speed – denotes the speed of the connection. The SATABoy is
capable of running at either 1Gbit (One Gigabit per second) or
2Gbit (Two Gigabits per second). You should set this speed
depending on your other Fibre Channel equipment. Auto mode will
attempt to negotiate the correct speed.
Frame Size – choose the frame size to be used. The frame size
relates to the data payload of each packet. Typically the larger the
payload the more data can be transmitted. The available frame
sizes are 512, 1024, 2048 and 2112.
After both interfaces have been configured click the ‘Save new
configuration’ button.
NOTE: The settings will be applied at the next restart of the system.
86
[16.02]
When operating in active-active mode the ‘configure fibre’ page
will show and allow configuration of the fibre ports on both
controllers, the corresponding controller number is indicated on the
left. Note that in ‘2 port active-active’ mode, 2 of the ports will
have a grey background to indicate that these are passive ports.
87
[w] www.nexsan.com
[16.03]
Cache
The SATABoy has a write cache memory which is normally enabled.
The cache memory holds data being written to disk. This enables
the controller to confirm that a command is completed before the
data has been physically written. In the event of a power failure
during an unfinished write operation, the cache has a battery
backup to protect cached data for up to three days. The SATABoy
controller will automatically complete any unfinished write
operations after power is restored.
Current write cache state – shows details about the current cache
configuration being used.
Manually override current write cache status – will force the
cache on or off without a reboot. Use the tick box if you wish to
use this option.
Desired write cache status – choose the preferred cache state. Use
the radio buttons to select Enable or Disable write cache.
Allow SCSI host to override write cache status – some SCSI
commands will force the write cache not to be used. Click the tick
box to override this.
88
Ignore force unit access (FUA) bit – When the FUA (Force Unit
Access) bit is set by a host system on a per command basis, data
is written and read directly to and from the disks without using
the onboard cache. This will incur a time overhead, but
guarantees the data is written to the disks. Set this option to
force the controller to ignore the FUA bit so that command
execution times are more consistent.
Write cache streaming mode – When the write cache is enabled
in streaming mode, the system continuously flushes the cache. This
provides maximum cache buffering to protect against raid system
delays adversely affecting command response times to the host.
When the write cache is in non-streaming mode, the system runs
with a full write cache to maximise cache hits and maximise
random IO performance.
Cache Optimization Setting – use these radio buttons to tune the
access performance of the cache. If your host system is accessing a
large number of different files or different areas of a volume then
selecting ‘random access’ may improve host performance. A file server
with a large number of users or a database may produce this type of
access pattern. If your host system is accessing a small number of
large files sequentially then selecting sequential access may improve
host performance. Streaming video may produce this type of access
pattern. If there is a mixture of sequential and random access then
selecting the ‘Mixed sequential / random’ option may improve overall
performance. Experimenting with these options is permissible in order
to determine which is best for your host system.
NOTE: The write cache will be flushed 5 seconds after the last host
write, it is recommended for a shutdown all host activity is stopped
and then wait 30 seconds before powering this system off.
Once you have made the required changes hit the ‘Save settings’
button to continue.
89
[w] www.nexsan.com
[16.04]
When operating in active-active mode you will have access to the
‘cache mirroring’ option. Enabling this ensures the write cache
memory of both controllers is kept synchronised. Should either
controller fail, the surviving controller will have correct and current
cache information that the failed controller was working with
before it failed. This will result in no cache write data being lost.
Disabling cache mirroring may mean write cache data is lost should
a controller fail.

Alarm
The audible alarm can be enabled or disabled using this page.
90
Silence the audible alarm – By clicking this button the audible
alarm will be silenced.
NOTE: This does not solve the problem that caused the alarm to sound.
Re-sound the audible alarm – click this button to enable the
audible alarm.
[16.06]
Lost Data
The Lost Data page is used to acknowledge and clear the warning
regarding missing data due to bad blocks.
When the RAID controller cannot reconstruct array data due to
there being no access to the redundant data (2 or more blocks not
accessible or using RAID 0) then you will see the ‘The RAID
controller has found some unrecoverable data blocks’ warning in
the problem page. Click the ‘Acknowledge lost data warning’
button to clear this warning.
NOTE: It is recommended that you then run a host based OS utility
that can detect and repair disk errors such as ‘scandisk’.
91
[w] www.nexsan.com
[16.07]
Reboot
The Reboot page allows the controller to be restarted or shutdown
without physical contact with the device.
Click the ‘Reboot Controller’ button to reboot the SATA RAID
controller. While the controller is rebooting the configured arrays
and volumes will not be accessible from your attached host
system(s), before this function is used it is advised that all host IO is
ceased. You may also need to reboot your host system(s) after the
RAID controller has rebooted.
Click ‘Shut Down Controller(s)’ to shutdown, this will ensure all the
cache data is flushed to the disks, when the SATABoy is put into a
shutdown state your host system(s) will not be able to access any
of the configured volumes.
[16.08]
Acknowledge Rebuild
When a RAID array has been through a reconstruct process, the
problem has to be manually acknowledged. This ensures the system
administrator is aware that a failed disk exists and a spare disk has
been used.
Click the “Acknowledge RAID Array Reconstruction” to clear the
reconstruction warning.
92
[16.09]
Rebuild Rate
The Rebuild Rate page can be used to select the amount of IO time
dedicated to rebuilding a critical array. If your host activity is high
then a higher rebuild priority may need to be selected so the array
rebuild completes in a shorter time. The disadvantage of doing this
is that less time will be dedicated to providing your host with data
and potentially reducing host data throughput. Bear in mind that
your data is vulnerable while an array is critical. Depending on RAID
level, any further disk failures could mean your data becomes
unavailable to your host i.e. RAID array goes offline.
To select a new rebuild rate click the appropriate radio button, then
click ‘Set Rebuild Priority’.
[16.10]
Verify Config (Configuration)
The Verify Config page allows the user to specify what type of
verification should be carried out on configured RAID arrays and
how often.
93
[w] www.nexsan.com
Select Verify Utility to use – Select ‘surface scan’ or ‘parity scrub’
to use for the next array verify utility. The selected utility will
execute after verify interval has expired. Surface scan uses up very
little array IO time. Surface scanning will make sure all data blocks
on all array disks can be read. Parity scrub uses much more time
and will read all the array data and make sure the parity
(redundant) data is intact. Any parity inconsistencies will be
corrected. Both utilities will correct (where possible) blocks that
cannot be read by using the parity data to rebuild the missing data
onto a remapped block. Only one verify utility can be active at any
one time for performance reasons. Multiple array configurations are
verified one at a time.
Verify Interval – Use the above settings to set the amount of time
between an array verify.
Execute verify utility NOW – click ‘Execute verify utility NOW’ to
run the selected utility immediately.
button to continue.
[16.11]
Spare Mode
The Spare Mode page allows the user to determine how disks
should be used when an array is critical.
Inserted disks automatically used as hot spares – any inserted
disk can immediately be used as a hot spare / rebuild disk.
NOTE: For a hot spare disk to be of use it must be at least the same
capacity as the smallest RAID array member.
94
Inserted disks must be manually configured as hot spares – any
newly inserted disk or an existing unused disk will not be used as a
rebuild disk, the disk must be configured as a hot spare by the user of
this system before the disk will be used by a degraded or critical array.
[16.12]
AA Config
This page allows the controller mode to be selected. Select ‘Single
controller mode’ when only one controller is installed. Select ‘2 port
active-active mode’ or ‘4 port active-active mode’ when two
controllers are installed. For differences between 2 and 4 port
active-active see the ‘Active-active mode operation’ section.
Kill Other Controller – this button will force a controller failure on
the other controller, in the above case controller 1, this button is
useful for testing your fail-over configuration. If you have
connected and configured your SATABoy system correctly for activeactive operation then killing the other controller should not affect
the attached host system(s).
95
[w] www.nexsan.com
[16.13]
Quick Start
Quick Start is an easy and quick way to set up the SATABoy.
This creates one RAID 5 array per controller and either one or two
volumes, depending on the setting selected. If you are using many
high capacity disks it may be the case that you end up with more
LUNs than expected, as the maximum LUN size is 2.2TB. If you
require LUNs to be over 2.2TB please contact technical support. All
volumes are mapped to both host ports. The Fibre Channel
interfaces are set to AUTO mode.
The default shipping configuration for the SATABoy is Quick Start
with one volume.
If your system has no arrays present Quick Start is a good way to
get started.
Form the GUI home page click on ‘Quick Start’ from the left frame.
The main frame will then display the default Quick Start
configuration, 1 volume config, this can be changed by clicking the
tabs on the top left of the main frame.
96
The available options are, ‘1 volume configuration’ and ‘2
volume configuration’.
Select the configuration that is most applicable to you. If neither fit
what you want to achieve you should consult the ‘Creating Custom
RAID arrays and Partitions’ section of the manual.
The main frame will then display the options and settings that will
be changed in order to complete the Quick Start process.
97
[w] www.nexsan.com
The Quick Start process will automatically change any settings that
are not already configured correctly. There is no need to change
anything before starting the process.
To continue you must click the confirm checkbox and then click the
‘Quick Start’ button.
NOTE: When in active-active mode the controller number will be
displayed and quickstart will configure two arrays, one per controller.
A final warning will appear to ensure that you are aware that any
current data will be destroyed.
Again, click the tick box and click ‘Confirm Quick Start Configure’
to continue or click the ‘CANCEL Quick Start’ button to cancel.

NOTE: When in active-active mode the owner controller number
will be shown for each disk, for example (C0) means the disk
belongs to controller 0.
[17.05]
Disk Stats
Disk Stats (Statistics) is the page that shows the access information
about the disks in the subsystem.
The picture above shows all the disks in the system and how
many times they have been accessed. Refer to the help below
for explanations.
IOs – Displays the number of requested IOs by the host system. The
individual figures represent each request. Bear in mind that a single
request may be up to 255 blocks long.
Transfer Retries – Displays the number of instances when a request
has failed because of a problem between the RAID controller and
disk. This counter will normally read 0.
107
[w] www.nexsan.com
Media Retries – Displays the number of instances when a request
has failed because of bad surface media on the hard disk. This will
normally read 0.
Read – The number of host read requests.

controller firmware.
When in active-active mode the controller number will be shown
next to the disk. (C0) means the disk is owned by controller 0 and
(C1) means the disk is owned by controller 1.
[17.06]
Bad Blocks
Bad blocks are areas of disk media that data can no longer be read
from. The SATABoy automatically re-maps single bad blocks to a
spare block when using a parity protected RAID level. However if
two bad blocks are discovered in the same stripe then data cannot
be reconstructed. This is most likely to happen during a rebuild,
when one disk is missing and another disk has a media error.
The page shows the number of bad blocks for each drive. Most
drives will never suffer from bad blocks. If there are bad blocks
present you can view where these are with the ‘Next’ button. Each
drive’s bad blocks can be viewed individually.

Problems
The Problem page is where you can view a summary of current
problems with the system.
119
[w] www.nexsan.com
Most of the time there will be no information in this page.
However in the unlikely event that your subsystem has a problem
this page will give you information about the fault. You can also
shortcut to this page by clicking the ‘green tick’ or ‘red cross’
(depending on subsystem status) located top right of the GUI.
NOTE: When in active-active mode problem messages will
normally have a controller number shown that indicates which
controller has the problem. When a controller number is not
shown the problem will not be related to a specific controller
but, for example, a failed PSU.
[18.07]
Event Log
The Event Log is like a diary of events kept by the controller.
Certain events will be recorded to the log, which is stored on the
installed hard disks.
120
The event log can be viewed in various ways using the filters.
In normal operation the event log is rarely used. It may be required
for you to email the event log to technical support if you are
experiencing difficulties.
The event log and config dump can be downloaded with a single
mouse click to the ‘Download event log and config dump’ link.
NOTE: When in active-active mode the controller number that posted
the event will be shown, for example see below, ‘C1’ indicates a
controller 1 event and ‘C0’ indicates a controller 0 event.

Additional Technical Information
APPA Quick Start Guide
What is APPA?
APPA is an acronym for Active Passive Passive Active and is the first of
two controller failover modes that can be selected on the SATABoy.
What do I need to run APPA?
The product must have two controllers installed. This feature
requires that the controllers be attached to your network using a
fabric switch.
How does APPA work?
APPA works by having two controllers. Each controller has an active
port and a passive port. The active port for each controller is used for
data transfer for the LUNs owned by that controller, the passive ports
remain dormant. Should a controller fail, the passive port of the
surviving controller becomes active and mimics the previously active
port of the failed controller. This is done by the passive port of the
surviving controller logging into the switch with the same WWN of
the previously active port of the failed controller. The RAID arrays of
the failed controller are passed to the surviving controller. The result is
that the connected host computers are not aware of the failure.
NOTE: It is essential that a fabric switch be utilized for this feature
to work correctly.
132
This is a typical APPA set up.
Both ports of both controllers are connected to the fabric switch. If a
controller were to fail the passive port of the surviving controller
would take over the failed controller’s active port. To understand how
this works it’s important to understand how a fabric switch operates.
133
[w] www.nexsan.com
When targets and initiators are logged in to a fabric switch their
world wide names (WWNs) are saved in the switch database.
During the log on process the new device will receive a list of other
devices connected to the switch.
When a controller fails, the passive port of the surviving controller
logs in, this then updates the database. Requests to the WWN of
the failed controller are now re-routed to the surviving controller.
Does APPA support multiple hosts?
Yes, multiple host computers are supported. LUN masking is also
available to make this easier to manage.
Does APPA support failback?
Failback is automatic. Controllers can only be inserted when the
system is powered off. When a new controller is inserted to replace
a failed controller, the configuration of the failed controller is
cloned to the new controller.
134
Do I need any third party software to use APPA?
No, the failover is done at the level of the switch. APPA will work
on any operating system that supports P2P mode fibre channel.
Failover is transparent to the host as it always sees the same
WWPN, even after a controller failure.
[19.02]
Active-active mode failover further information
Here is how Active – Passive – Passive – Active works.
Here you can see that one port on each controller is active. The
other port on each controller is passive. The active port is used to
access the RAID arrays dedicated to that controller. The passive port
also actually logs into the switch but does not present any LUNs.
Each controller has one accessible path.
135
[w] www.nexsan.com
In the event of a controller failure the passive port logs out of the
fabric and then logs back in using the WWN of the previously active
port of the failed controller.
The RAID arrays owned by the failed controller are now accessible
from the surviving controller. The LUN mapping and masking is
preserved during the process.
As the port logs in as the previous WWN then the OS does not
notice any difference. No additional drivers are required and the
process is seamless.
136
[19.03]
Four Port active-active operation
With ‘Four Port active-active’ all the fibre ports are active. Both
ports on a controller show the same LUNs but have different
WWNs. So each LUN that is mapped has two paths to it.
To the OS a disk mapped this way will look like two disks. This is
why a solution like this requires third party software in order to
load balance and failover correctly. With qualified failover software
installed (Veritas DMP for example) the OS will see a single disk for
each LUN. The OS will be aware that there are two paths and in the
event of only one path being available (due to a controller failure
or link failure) the OS will switch to the surviving path, with no user
intervention required.
137
[w] www.nexsan.com
The failover works in much the same way as the APPA model.
[19.04]
Controller Replacement
In most situations, when a controller is replaced, the replacement
will automatically inherit the same configuration and system
settings as the original that it is replacing.
Under some circumstances however, the correct configuration
cannot be determined automatically - for example when the
controller has previously been used in another system. In this case,
a ‘cloning’ page will be presented both on the serial port and on
the web interface (at the replacement controller’s default IP
address), presenting you with a choice between using a controller
configuration stored on the disks or using the configuration stored
in the controller’s flash memory.
If you are fitting a replacement controller to a functional system,
you should select ‘n’ to use the configuration stored on the disks. If
you are installing a replacement disk set or chassis, you should
select ‘c’ to use the configuration stored in the controller’s flash
memory. If you are unsure which option is correct for your
situation, contact technical support for more information.

Troubleshooting
Web Interface Problems
When I type in the IP address I have assigned to NexScan in my
web browser nothing happens?
Check that system is responding.
The best way to contact the SATABoy unit is with a ping utility.
Different operating systems have different ping utilities, but they
are on the whole very similar. We will use Microsoft for the purpose
of this guide.
Open a DOS window and retreat to the root level of the C drive (or
the drive that has the currently loaded Operating System), to do
this type
cd \
Then attempt to ‘ping’ the Nexsan unit. Type:
C:\> ping 192.1.168.225
NOTE: Replace the above address with your SATABoy’s IP address.
If the ping is successful you will see a similar response to the one below.

If you have a successful reply but cannot access the home page
please consult technical support.
If no reply is returned check that you are using the right IP address.
If you are using DHCP, check that the DHCP has allocated an
address to NexScan. If there is no reply you can perform a SCSI
scan. When scanning SCSI device you will see an ‘inquiry string’
that reports back the size, name and speed of a device. You can
normally see this information when your computer is booting.
When the SATABoy is scanned the reply is SATABy(xxxxxxxx), the x’s
in parenthesis should be numbers in HEX that is the IP address. To
decode this address take the first two numbers i.e. B1
B1 (hex) = 177 (decimal)
Repeat this until you have all four decimal numbers of the IP address.
If you still get no reply you should attempt to reset the IP address
manually. Use the serial port. Please refer to the main set up guide.
When I am using the menus I am being asked to provide a
username and password?
You probably have security turned on. The username “ADMIN” and
password “PASSWORD” (both uppercase without quote marks) will
allow you to access any page.
The default user name and password are not responding, what do I do?
Make sure that you are entering the username and password in
UPPERCASE, as this logon is case sensitive. If this is not the case the
user name and password may have been changed from the original
factory settings.
You can reset the password using the serial port interface.
Use the ‘Getting Started’ section to see how set up your computer
to run with the serial port.
140
When logged on to the serial port, use the cursor keys to navigate
the menus.
From the main menu go to
System Admin >> Set GUI ‘Admin’ password
Type the new password into the supplied box.
The password is set immediately.
[20.02]
Start Up Problems
When I power up my subsystem it beeps. What is the problem?
The subsystem will beep for a variety of reasons. A beeping unit
does not mean that the unit is broken. If you have email enabled
check your inbox. This will probably provide a clear explanation of
where the problem lies.
You can also find the current problems using either the Web interface
by clicking the red X in top right corner of the home page.
Another way to discover problems is by checking the lights on
the unit.
The front panel LEDs are clearly marked and will give an indication
to where the problem lies.
For further help contact your technical support.
When I start up the Battery LED is flashing. Is my battery dead?
No. The flashing LED means that the battery state is unknown or
charging. It is normal for this light to flash for the first 10 minutes
of operation as the battery state is unknown.
If the flashing persists after ten minutes the battery is charging. If
the LED is solid red after ten minutes the battery has failed and
needs replacing.

Resolving Problems
The NexScan Interface has told me that a disk has failed. My data is
still online. What should I do?
If a disk has failed you will need to find out which one it is. Do this
by using the web GUI, you should extract the faulty disk, DO NOT
re-use a failed disk in the system even if it appears to have no fault.
Then contact your dealer regarding a replacement. Arrange for a
replacement as soon as possible, as your array may be in a critical
state. When the replacement module arrives you should check that
no damage has been caused during transit and then insert into the
empty slot. The SATABoy will detect the new disk and rebuild to it
if the array is critical. If you already had a spare disk the SATABoy
will assign the new disk as a spare too, check this has happened
using the web GUI.
A power supply has failed. My system still works but what should I do?
Do not remove the faulty power supply! Removing a power supply
will drastically reduce airflow and cooling, potentially resulting in
over heating the system. Contact your dealer regarding a
replacement PSU. Only remove the failed PSU when the
replacement arrives.
My RAID controller has failed. What should I do?
If a RAID controller fails you will not be able to access your data.
Your data will be safe on the disks until a replacement controller
arrives*. Leave the controller in place and contact your dealer for a
replacement.
*Data in write cache will be lost if a controller fails in non-AA systems.
Please contact your dealer for help with any other queries.

How do I upgrade the firmware?
Nexsan Technologies will occasionally make new firmware available
for the SATABoy. New firmware may include new features and
ensure the smooth running of the SATABoy system.
Using the GUI interface to upload the firmware.
It is advised to power cycle unit before uploading the firmware
1) Unzip the firmware file to your C:\ directory
2) Open the SATABoy GUI by typing the SATABoy IP address into
Internet Explorer and click go or press return.
3) Log in if required, note the default username is: ADMIN and
default password is: PASSWORD, although you may of changed
these default settings, if so use your SATABoy administrator
username (ADMIN) and your configured password.
4) Once logged in and at the main window, in the address bar type
after the SATABoy IP address ‘/admin/fwupdate.asp’ then press
enter. (e.g. 172.16.1.210/admin/fwupdate.asp)
5) Click on the browse button to find the file you extracted to the
C:\ directory, select the firmware file and click open.
6) Once the file is selected, click the upload firmware button,
after the file is uploaded (which may take some period of time
to be sent, depending on the network connection speed) you
should see:
DO NOT SWITCH THE ATA RAID SYSTEM OFF until you are sure the firmware
update has finished
Firmware update has started
Click this text to see the current firmware update status

143
[w] www.nexsan.com
7) To view the progress click the link Click this text to see the
current firmware update status and a RED window with the
progress will appear.
8) You should double check that the unit has finished upgrading
the firmware by checking that you can see all of the following
messages in the event log, the most important message to look
for is ‘Microcode Updated OK’. If you don’t see this message DO
NOT switch the system off otherwise this may render your
SATABoy unusable.
0000: 09_Aug_2003 at 15:25:10: Microcode Updated OK

0003: 09_Aug_2003 at 15:22:31: Starting microcode update
DO NOT POWER CYCLE THE SATABOY UNTIL YOU SEE THE MESSAGE
MICROCODE UPDATED OK IN THE EVENT LOG.
For dual controller systems see below:
9) For the second controller repeat steps 4 through to 8, then
continue to step 10, using the IP address of the second
controller.
10)You may reboot remotely by going to Controller Admin then the
reboot tab, check to confirm, or power off the SATABoy for 10
seconds and then power back on. Once the controller is up
power on the server.
144
[21.01]
Using FTP to upload the firmware
It is advised to power cycle unit before uploading the firmware.
1) Unzip the firmware file to your C:\ directory
2) FTP to the IP address of the SATABoy, enter the username:
‘ADMIN’ and the password: PASSWORD or whatever your
currently configured ADMIN password is.
3) Once a connection is established type lcd \ to take you to the C:\
directory then type ‘put firmware’, where ‘firmware’ is the
filename of the firmware file.
4) Once the file has been transferred you will see ‘Connection
closed by remote host’.
5) Open the GUI interface of the SATABoy and you should see the
progress of the firmware update.
6) You should double check that the unit has finished upgrading
the firmware by checking that you can see all of the following
messages in the event log, the most important message to look
for is ‘Microcode Updated OK’. If you do not see this message
DO NOT switch the system off otherwise this may render your
SATABoy unusable.
