A fire suppression system is the responsibility of the customer. The customer’s own
insurance underwriter, local fire marshal, or a local building inspector, or both,
should be consulted in selecting a fire suppression system that provides the correct
level of coverage and protection. IBM designs and manufactures equipment to
internal and external standards that require certain environments for reliable
operation. Because IBM does not test any equipment for compatibility with fire
suppression systems, IBM does not make compatibility claims of any kind nor does
IBM provide recommendations on fire suppression systems.
Table 9 on page 8 lists the environmental specifications for the FAStT600.

Chapter 1. Introduction
IBM FAStT (Fibre Array Storage Technology) solutions support the large and
growing data storage requirements of business-critical applications. These scalable
IBM FAStT solutions offer you data access and protection to meet your existing
enterprise storage requirements and prepare for the future.
Fibre channel is a new technology, similar to a high-speed network, that you can
use to connect large amounts of disk storage to a server or cluster of servers. Fibre
Channel technology supports increased performance, scalability, availability, and
distance for attaching storage subsystems to network servers. The storage server
provides for the attachment of Fibre Channel disk drives to give superior
performance and redundancy.
Fibre channel technology supports applications that require large amounts of disk
storage that is shared by two or more servers. With fibre channel, you can see a
higher throughput rate over longer distances than is possible with small computer
system interface (SCSI) or with serial storage architecture (SSA) technology.
The IBM TotalStorage FAStT600 Storage Server (Machine Type 1722, Models 60U
and 60X) comes with two RAID controllers, two power supplies, and two cooling
units and provides dual, redundant controllers, redundant cooling, redundant power,
and battery backup of the RAID controller cache. The FAStT600 Storage Server is
designed to provide maximum host and drive side redundancy. Each RAID
controller supports direct attachment of one host containing one or two host
adapters.
FAStT600 supports up to fourteen internal disk drive modules, supporting over 2
TBs of storage capacity. Additional storage can be added to the FAStT600 with up
to two FAStT EXP700 Expansion Units using optional EXP700 Attachment features
(feature number 7360, or features number 7361 and number 7362). Utilizing these
features, up to 42 disk drives can be attached to the FAStT600 with individual drive
module capacities ranging from 36.4 GB to 146.8 GB.
After you review the introductory information that is provided in this chapter, go to
Chapter 2, “Installing and configuring the storage server”, on page 11 to begin the
installation process.

Handling static-sensitive devices
Attention: Static electricity can damage electronic devices and your system. To
avoid damage, keep static-sensitive devices in their static-protective package until
you are ready to install them.
To reduce the possibility of electrostatic discharge (ESD), observe the following
precautions:
v Limit your movement. Movement can cause static electricity to build up around
you.
v Handle the device carefully. Hold it by its edges or its frame.
v Do not touch solder joints, pins, or exposed printed circuitry.
v Do not leave the device where others can handle and possibly damage the
device.
v While the device is still in its static-protective package, you should hold the
device and touch an unpainted metal part of the system unit for at least two
seconds. This drains static electricity from the package and from your body.
v Remove the device from its package and install it directly into your system unit
without setting it down. If it is necessary to set the device down, place it in its
static-protective package. Do not place the device on your system unit cover or
on a metal table.
v Take additional care when handling devices during cold weather because heating
reduces indoor humidity and increases static electricity.
Best practices guidelines

|
|
|
|
|
|
|
|
To ensure optimal operation of your system, always follow these best practices
guidelines:
v Back up the data on your storage drives periodically.
v To maintain power redundancy, plug the FAStT600 Storage Server’s right and the
left power supplies into two independent external power circuits through ac
distribution units inside a rack cabinet or directly into external receptacles.
Similarly, the right and left power supplies of the FAStT drive enclosures attached
to the FAStT600 Storage Server should be plugged into the same two
independent external power circuits as the FAStT600 Storage Server. This

ensures that the FAStT600 Storage Server and all its attached drive enclosures
will have power if only one power circuit is available. In addition, having all the
right or all the left power supplies plug into the same power circuit will enable the
components in the storage subsystem to power on simultaneously during an
unattended restoration of power. See Figure 32 on page 34 for an example of
redundant power connections.
v Before any planned system shutdown or after any system changes (additions,
removals, or modifications), save controller subsystem profiles as explained in
the Storage Manager guide for your operating system.
v Ensure that your system is in an optimal state before shutting down. Never turn
the power off if any fault light is lit; be sure to resolve any error conditions before
you shut down the system.
v During any maintenance or attended power-up procedure, carefully follow the
power-up sequence listed in “Turning on the storage server” on page 38. Each
component of the subsystem should be checked that it is powered-on in the
proper order during this entire power-up procedure to ensure the controller will be
able to optimally access all of your storage subsystems.
v The storage subsystem supports simultaneous power-up to the system
components; however, you should always follow the power-up sequence listed in
“Turning on the storage server” on page 38 during any attended power-up
procedure.
v A storage system in an optimal state should recover automatically from an
unexpected shutdown and unattended simultaneous restoration of power to
system components. After power is restored, call IBM support if any of the
following conditions occur:
– The storage subsystem logical drives and arrays are not displayed in the
Storage Manager graphical user interface (GUI).
– The storage subsystem logical drives and arrays do not come online.
– The storage subsystem logical drives and arrays seem to be degraded.
Storage server components
The following sections show the components of the storage server.
The hot-swap features of the storage server enable you to remove and replace hard
disk drives, power supplies, RAID controllers, and fans without turning off the
storage server. Therefore, you can maintain the availability of your system while a
hot-swap device is removed, installed, or replaced.

Heat output, airflow, and cooling
The maximum heat output of the FAStT600 is 390 watts (1330 BTU/hr). Each
FAStT600 (machine type 1722) and drive expansion (EXP700) rack-mounted unit
requires an airflow of 2.5 m
temperature to all racks is recommended to be in the range 10°C through 35°C
(50°F through 95°F), with a recommended operating temperature of 22°C (72°F).
When racks that contain many 1722 units are to be installed together, the following
requirements must be met to ensure that the 1722 units are adequately cooled:
v Air enters at the front of the rack and leaves at the back. To prevent the air that
is leaving the rack from entering the intake of another piece of equipment, racks
must be positioned in alternate rows, back-to-back and front-to-front. This
arrangement is known as “Cold Aisle / Hot Aisle” and is shown in Figure 5 on
page 9.
v Where racks are in rows, each rack must touch the rack that is next to it to
reduce the amount of hot air that can flow around from the back of the rack into
the intakes of the 1722 units that are in that rack. It is recommended that Suite
Attach Kits be used to completely seal any gaps that remain between the racks.
For details of Suite Attach Kits, contact your marketing representative.

Installing the storage server in a rack
Review the documentation that comes with the rack cabinet for safety and cabling
information. When you install the storage server in a rack, consider the following
factors:
v Ensure that the room air temperature is below 35°C (95°F).
v Do not block any air vents. Usually, leaving 15 cm (6 in.) of air space provides
proper airflow.
v Plan the device installation starting from the bottom of the rack.
v Do not extend more than one device out of the rack at the same time.
v Remove the rack doors and side panels to provide easier access during
installation.
v Connect all power cords to properly wired and grounded electrical outlets.
v Take precautions to prevent overloading the power outlets when you install
multiple devices in a rack.
Statement 4:
≥ 18 kg (39.7 lb) ≥ 32 kg (70.5 lb) ≥ 55 kg (121.2 lb)

Setting server ID settings
The FAStT600 comes with a server ID switch that is used to identify the FAStT600
on a Fibre Channel loop. The server ID switch is located on the back of the unit, as
shown in Figure 16 on page 19.
18 IBM TotalStorage FAStT600 Fibre Channel Storage Server: Installation and User’s Guide
Server ID Switch
Figure 16. Setting the Server ID
Server ID switch settings set the server ID to a value from 00 - 77. Server ID switch
X1 is for setting the ones position, and Server ID switch X10 is for setting the tens
position. The settings of the two server ID switches, when used together, provide a
two-digit ID of the server unit. The storage-management software uses the server
ID to provide a correlation between the storage-management graphics and the
physical storage unit. The ID indicates which physical unit corresponds to the
storage-management software status.
Use Server ID switches X10 and X1 to set the server-unit ID to any value from 0
through 7.
Note: Each server unit should have a unique ID if it is going to be connected to
other drive expansion units through the drive loop ports. The Server ID
setting is only valid for the drive loop. The amber Conflict LED (located on
the right-side of the switch) will be lit if there is another unit in the drive loop
that has the same ID setting as the server ID. See your storage server
documentation for more information.
Configuring the storage subsystem
You must configure the storage subsystem configuration after you install the storage
server in a rack. Use the information in the following sections to configure your
storage subsystem configuration.
Storage subsystem management methods
Before you configure the storage subsystem, determine which method of storage
subsystem management you want to use. You can manage the storage subsystems
in either of two ways: Host-agent management or Direct-management.
Chapter 2. Installing and configuring the storage server 19
Host-agent management method:
This method uses host-agent software that is installed on the host server. You must
install at least one management station and a software-agent host. The
management station can be the host or a workstation on the Ethernet network. A
management station will have the client software installed. Figure 17 shows the
host-agent management method.

Direct-management method:
This method uses Ethernet connections from a management station to each
controller. You must install at least one management station. The management
station can be the host or a workstation on the Ethernet network. A management
station will have the client software installed. Attach Ethernet cables to each
management station (one pair per storage server). You will connect the cables to
each controller later when you install the storage server. Figure 18 shows the direct
management method.

Fibre Channel connections
The storage server Fibre Channel consists of a host Fibre Channel loop and a drive
Fibre Channel loop. The host Fibre Channel loop provides the fibre path for host
attachment. It can consist of Fibre Channel cables, SFPs, host bus adapters, Fibre
Channel switches, and RAID controllers. The drive Fibre Channel loop provides the
fibre path to the hard disk drives (HDDs). The drive Fibre Channel loop consists of
Fibre Channel HDDs and optional drive expansion units, Fibre Channel cables, and
SFPs.
The FAStT600 Storage Server supports redundant disk-drive-loop configurations.
Each RAID controller has three SFP ports. These SFP ports are labeled ″Host 1″,
″Host 2″, and ″Expansion″. You can build a redundant drive loop by connecting one
or more expansion units to the redundant RAID controllers. Then, use dual
Management station
Chapter 2. Installing and configuring the storage server 21
fiber-optic cables to connect one expansion unit to another in a daisy-chain. For
more information about adding expansion units, see “Connecting additional
expansion units” on page 35.
Fibre Channel loop configurations
You must determine how the host systems will connect to the storage server. You
can connect up to two host systems directly to the storage server, or you can
connect more than two hosts to the storage server through switches. The
illustrations in the following sections show common host system configurations.
Note: The default is one partition. Four-partition and eight-partition configurations
are provided as option upgrades, as is the option of additional attachments
to expansion units (EXPs). Contact your IBM resellers or marketing
representatives for more information.
Redundant host and drive loops
This section provides examples of FAStT600 host Fibre Channel configurations,
including:
v Redundant host and drive loop Fibre Channel configurations in Figure 19 on
page 23

Chapter 3. Cabling the storage server
This chapter provides Fibre Channel and power cabling information for the storage
server.
After you attach the storage server power cables, use the instructions that are
provided in “Turning the storage server on and off” on page 37 for the initial startup
of the storage server.
Working with SFPs and fiber-optic cables
Each RAID controller has two host ports and one expansion port. An SFP is used to
connect each host port and expansion port to hosts and expansion units. The SFP
is inserted into the port, and then a fiber-optic cable is inserted into the SFP. The
other end of the fiber-optic cable connects to an external device. SFPs are laser
products.
Statement 3
CAUTION:
When laser products (such as CD-ROMs, DVD drives, fiber optic devices, or
transmitters) are installed, note the following:
v Do not remove the covers. Removing the covers of the laser product could result in
exposure to hazardous laser radiation. There are no serviceable parts inside the
device.
v Use of controls or adjustments or performance of procedures other than those
specified herein might result in hazardous radiation exposure.
Danger
Some laser products contain an embedded Class 3A or Class 3B laser diode. Note the
following.
Laser radiation when open. Do not stare into the beam, do not view directly with optical
instruments, and avoid direct exposure to the beam.
Handling fiber-optic cables
Before using fiber-optic cables, read the following precautions.
Attention: To avoid damage to the fiber-optic cables, follow these guidelines:
v Do not route the cable along a folding cable-management arm.
v When attaching to a device on slide rails, leave enough slack in the cable so that
it does not bend to a radius of less than 38 mm (1.5 in.) when extended or
become pinched when retracted.
v Route the cable away from places where it can be snagged by other devices in
the rack.
© Copyright IBM Corp. 2003 27
v Do not overtighten the cable straps or bend the cables to a radius of less than 38
mm (1.5 in.).
v Do not put excess weight on the cable at the connection point. Be sure that the
cable is well supported.
Installing SFP modules
The FAStT600 Storage Server host ports require Small Form-Factor Pluggable
(SFP) Modules. SFP modules are used to convert electrical signals to optical
signals that are required for Fibre Channel transmission to and from RAID
controllers. The FAStT600 Storage Server supports two types of SFP modules; one
with a plastic latch and one with a wire latch. After you install the SFP modules, you
will use fiber-optic cables to connect the FAStT600 Storage Server to other Fibre
Channel devices.
Before you install SFP modules and fiber-optic cables, read the following
information:
v The SFP module housing has an integral guide key designed to prevent you from
inserting the SFP module improperly.
v Use minimal pressure when you insert the SFP module into a port. Forcing the
SFP module into a port could cause damage to the SFP module or the port.
v You can insert or remove the SFP module while the port is powered on.
v The operational loop performance is not affected when you install or remove an
SFP module.
v You must insert the SFP module into a port before you connect the fiber-optic
cable.
v You must remove the fiber-optic cable from the SFP module before you remove
the SFP module from the port. See “Removing SFP modules” on page 30 for
more information.
To install an SFP module, complete the following steps.
Statement 3:
CAUTION:
When laser products (such as CD-ROMs, DVD drives, fiber-optic devices, or
transmitters) are installed, note the following:
v Do not remove the covers. Removing the covers of the laser product could
result in exposure to hazardous laser radiation. There are no serviceable
parts inside the device.
v Use of controls or adjustments or performance of procedures other than
those specified herein might result in hazardous radiation exposure.
28 IBM TotalStorage FAStT600 Fibre Channel Storage Server: Installation and User’s Guide
DANGER
Some laser products contain an embedded Class 3A or Class 3B laser
diode. Note the following.

the online help to configure the logical drives, partitions, and so on for the RAID
controllers. Use your operating system documentation to make the new logical
drives accessible to the operating system.
Note: Make sure that you start the storage-management software to continuously
monitor the status of the storage server. For information about the
importance of this information, see “Monitoring status through software” on
page 41.
34 IBM TotalStorage FAStT600 Fibre Channel Storage Server: Installation and User’s Guide
Connecting additional expansion units
After you install the storage server, you can connect additional expansion units. You
can do this at any time after you install the storage server, even while it is turned on
and processing data. You can even install one expansion unit now and an additional
expansion unit later.
Note: You must purchase an option to connect additional drive expansion
enclosures to the FAStT600 storage server. Contact your IBM resellers or
marketing representatives for more information.
Attention: You can add only new expansion units to the storage server. This
means that there must be no existing configuration information on the expansion
unit that you want to install. If the expansion unit that you want to install currently
contains logical drives or configured hot spares, and you want them to be part of
the FAStT600 storage server, you must contact IBM for information. Improper drive
migration might cause loss of configuration and other storage server problems.
To connect an additional expansion unit, perform the following steps.
1. Follow the instructions in your expansion unit installation manual to set up and
mount the new expansion unit.
2. Use the following procedure and illustration to connect a single expansion unit
to the storage server:
a. Use a fiber-optic cable to connect to the FC-Expansion Units port on the left
RAID controller in the storage server to the In port on the left ESM board of
the expansion unit.
b. Use a second fiber-optic cable to connect the FC-Expansion Units port on
the right RAID controller in the storage server to the Out port on the right
ESM board of the expansion unit.
c. Ensure that the enclosure ID switch is set to a value different from one set
for the FAStT600 server and other drive expansion enclosures in the loop.
Also, ensure that the link speeds of the expansion units are set to 2 Gb.

To ensure optimal operation of your system, always follow these best practices
guidelines:
v Back up the data on your storage drives periodically.
v To maintain power redundancy, plug the FAStT600 Storage Server’s right and the
left power supplies into two independent external power circuits through ac
distribution units inside a rack cabinet or directly into external receptacles.
Similarly, the right and left power supplies of the FAStT drive enclosures attached
to the FAStT600 Storage Server should be plugged into the same two
independent external power circuits as the FAStT600 Storage Server. This
ensures that the FAStT600 Storage Server and all its attached drive enclosures
will have power if only one power circuit is available. In addition, having all the
right or all the left power supplies plug into the same power circuit will enable the
components in the storage subsystem to power on simultaneously during an
unattended restoration of power. See Figure 32 on page 34 for an example of
redundant power connections.
v Before any planned system shutdown or after any system changes (additions,
removals, or modifications), save controller subsystem profiles as explained in
the Storage Manager guide for your operating system.
v Ensure that your system is in an optimal state before shutting down. Never turn
the power off if any fault light is lit; be sure to resolve any error conditions before
you shut down the system.
v During any maintenance or attended power-up procedure, carefully follow the
power-up sequence listed in “Turning on the storage server” on page 38. Each
component of the subsystem should be checked that it is powered-on in the
proper order during this entire power-up procedure to ensure the controller will be
able to optimally access all of your storage subsystems.
v The storage subsystem supports simultaneous power-up to the system
components; however, you should always follow the power-up sequence listed in
“Turning on the storage server” on page 38 during any attended power-up
procedure.
v A storage system in an optimal state should recover automatically from an
unexpected shutdown and unattended simultaneous restoration of power to
system components. After power is restored, call IBM support if any of the
following conditions occur:
– The storage subsystem logical drives and arrays are not displayed in the
Storage Manager graphical user interface (GUI).
– The storage subsystem logical drives and arrays do not come online.
– The storage subsystem logical drives and arrays seem to be degraded.
Turning the storage server on and off
This section contains instructions for turning the storage server on and off under
normal and emergency situations.
If you are turning on the storage server after an emergency shutdown or power
outage, see “Restoring power after an emergency shutdown” on page 41.

Turning on the storage server
|
|
|
|
|
|
|
|
|
Important: You must turn on the drive enclosures and verify that the drive
enclosures’ FC connections are optimal by checking the indicator lights
before you turn on the FAStT600 Storage Server. The controllers might
not recognize the correct configuration if the hard disk drives are
powered up after the FAStT600 Storage Server. For instructions on
powering up the drive enclosures, refer to the drive enclosure
documentation.
Note: Always wait at least 30 seconds between the time you turn off a power
switch and the time you turn on the power again.
Use this procedure to turn on the power for the initial startup of the storage server:
1. Verify that:
a. All communication and power cables are plugged into the back of the
storage server and a properly grounded ac electrical outlet
b. All hard disk drives are locked securely in place. For more information, see
“Installing hot-swap drives” on page 50.
Note: At least one drive must be present before you start the FAStT600.
Attention: If you are restarting the system after a normal shutdown, wait at
least 10 seconds before you turn on the power by using the power-on sequence
in step 2.
2. Check the system documentation for the hardware devices that you intend to
power up, and then determine the proper startup sequence. Use the following
power-on sequence, where applicable:
a. Turn on the power to the supporting devices (for example, Ethernet switches
and management stations) before the storage server.
Attention: If you will be directly managing the storage array, you must set
up the Dynamic Host Configuration Protocol (DHCP) or BOOT-P server
before turning on the power. Setting up the server allows the controllers to
obtain the corresponding IP address when you turn on the power to the
array module. For more information, see the software installation guide for
your operating system.
b. You must turn on the expansion units before the storage server. The
controllers might not recognize the correct configuration if the drives are
powered up after the storage server. For instructions on powering up the
expansion units, see the expansion-unit documentation.
c. Turn on the power to the storage server; then restart or turn on the power to
the host.
Note: Depending on your operating system, you might not have to restart
3. Turn on the power to each device, based on the power-on sequence in step 2.
To turn on power to the storage server, turn on the power-supply switches on
the back of the storage server. You must turn on both power-supply switches to
take advantage of the redundant power supplies.
4. Use the storage-management software and the Fault LEDs to check the overall
status of the storage server and its components. All LEDs should be green on
the front of the storage server. If they are not, use the storage-management
software to diagnose the problem (see “Monitoring status through software” on
page 41).
38 IBM TotalStorage FAStT600 Fibre Channel Storage Server: Installation and User’s Guide
the host. For more information, see the software installation guide for
your operating system.
Note: The green Drive active LED and amber Drive fault LED below the drive
CRUs might flash intermittently as the drives spin-up. Wait until the
storage server is finished powering up before checking the LEDs on the
front of the storage server. For more information, see “Checking the
LEDs” on page 42.
Turning off the storage server

|
|
|
|
|
|
Attention: Except in an emergency, never turn off the power if any storage server
Fault LEDs are on. Correct the fault before you turn off the power. Use the
storage-management software and the Fault LEDs to check the overall status of the
storage server and its components. All LEDs should be green on the front of the
storage server. If they are not, use the storage-management software to diagnose
the problem (see “Monitoring status through software” on page 41). This ensures
that the storage server will power up correctly later. For more information, see
“Troubleshooting” on page 74.
The storage server is designed to run continuously, 24 hours a day. After you turn
on the storage server, do not turn it off. Turn off the power only when:
v Instructions in a hardware or software procedure require you to turn off the
power.
v A service technician tells you to turn off the power.
v A power outage or emergency situation occurs (see “Performing an emergency
shutdown” on page 41).
Statement 5
CAUTION:
The power control button on the device and the power supply do not turn off the
electrical current supplied to the device. The device also might have more than one
power cord. To remove all electrical current from the device, ensure that all power
cords are disconnected from the power source.

Use this procedure to turn off the power:
1. Before proceeding, use the storage-management software to determine the
status of the system components and special instructions. The operating system
software might require you to perform other procedures before you turn off the
power.
2. Use the storage-management software to check the status of the storage
server. Correct problems that are reported before you turn off the power.
3. Perform the following steps:
a. Stop all I/O activity to the storage server and attached expansion units.
Make sure that:
v All of the green Drive active LEDs on the front of the storage server (and
on all attached expansion units) are not flashing.
Chapter 4. Operating the storage server 39
v The green Cache active LEDs on the back of the storage server are off.
b. If applicable, use the operating system software to disconnect the storage
server logical drives from the host before the storage server is powered off.
Attention: To turn off all power to the storage server, you must turn off both
power-supply switches and disconnect both power cords. Use the procedure in
step 4 for the proper shutdown sequence.
4. Turn off the power to each device based on the following shutdown sequence:
a. Turn off power to the host before the storage server. If the host must stay
powered on to support an existing network, see the operating system
documentation for information about disconnecting the storage server logical
drives from the host before the storage server is powered off.
b. Turn off power to the storage server before you turn off power to the
expansion units. Turn off both power supply switches on the back of the
storage server.
c. Turn off power to other supporting devices (for example, management
stations, fibre-channel switches, or Ethernet switches).
Note: You do not need to perform this step if you are servicing only the
storage server.
5. After you perform the necessary maintenance procedures, turn on the power
using the procedure in “Turning on the storage server” on page 38.
Restoring power after an unexpected shutdown
The storage server might shut down unexpectedly under any of the following
conditions:
Attention: There might be data loss in each of the following cases:
v The internal temperature of the storage server exceeds the maximum operating
temperature (an over-temperature condition).
If both fan CRUs fail or are unable to maintain an internal temperature below
70°C (158°F), one or both of the power supplies in the storage server will shut
down. If both power supplies shut down, the unit is inoperable.
The storage-management software warns you if the temperature of the unit is
rising, before it has risen sufficiently to shut down the power supplies. The first
warning comes when the storage server internal temperature exceeds 45°C
(113°F). The storage server shuts down if the temperature rises to 70°C (158°F).
v There is a general power failure or a loss of power to the unit.
v You are forced to shut down the storage server without performing the normal
shutdown procedures (listed in “Turning off the storage server” on page 39)
because of an emergency situation.
Attention: To avoid damage to the hardware, take special care when restarting
the system after an unexpected shutdown.
|
|

If the storage server shuts down unexpectedly, go to “Restoring power after an
over-temperature shutdown” on page 41. Otherwise, go to “Restoring power after an
emergency shutdown” on page 41.

Note: Unattended restoration of power is supported; however, if power restoration
is attended, you should follow the best practices guidelines and the power
restoration sequence in “Turning on the storage server” on page 38.
40 IBM TotalStorage FAStT600 Fibre Channel Storage Server: Installation and User’s Guide
Performing an emergency shutdown
Attention: Emergency situations might include fire, flood, extreme weather
conditions, or other hazardous circumstances. If a power outage or emergency
situation occurs, always turn off all power switches on all computing equipment.
This will help safeguard your equipment from potential damage due to electrical
surges when power is restored. If the storage server loses power unexpectedly, it
might be due to a hardware failure in the power system or midplane (see
“Troubleshooting” on page 74).
Use this procedure to shut down the storage server during an emergency:
1. If you have time, stop all I/O activity to the storage server by shutting down the
host or disconnecting the storage server logical drives through the host.
2. Check the LEDs (front and back). Make note of any Fault LEDs that are on so
you can correct the problem when you turn on the power again.
3. Turn off all power-supply switches; then unplug the power cords from the
storage server.
Restoring power after an emergency shutdown
Use this procedure to restart the storage server if you turned off the power-supply
switches during an emergency shutdown, or if a power failure or a power outage
occurred:
1. After the emergency situation is over or power is restored, check the storage
server for damage. If there is no visible damage, continue with step 2;
otherwise, have your system serviced.
2. After you have checked for damage, ensure that the power-supply switches are
off; then plug in the storage-server power cords.
3. Complete step 2 on page 38 to determine the proper power-on sequence for
your system.
4. Complete steps 3 and 4 on page 38 to turn on power to the devices in your
system and to check the status of the storage server.
Restoring power after an over-temperature shutdown
Use this procedure to restart the storage server after an unexpected shutdown due
to an over-temperature condition:
1. Make sure that the power-supply switches on the back of the storage server are
turned off.
2. Do whatever is necessary to cool the unit (replace the fans, use external fans to
cool the room, and so on).
3. Check all components and cables for visible damage. Do not start the storage
server if you find evidence of damage.
4. Complete step 2 on page 38 to determine the proper power-on sequence for
your system.
5. When the internal temperature of the storage server is below 35°C (95°F),
complete steps 3 and 4 on page 38 to turn on power to the devices in your
system and to check the status of the storage server.
Monitoring status through software
Use the storage-management software to monitor the status of the storage server.
Run the software constantly, and check it frequently.
Chapter 4. Operating the storage server 41
The storage-management software provides the best way to diagnose and repair
storage-server failures. The software can help you:
v Determine the nature of the failure
v Locate the failed component
v Determine the recovery procedures to repair the failure
Although the storage server has fault LEDs, these lights do not necessarily indicate
which component has failed or needs to be replaced, or which type of recovery
procedure you must perform. In some cases (such as loss of redundancy in various
components), the fault LED does not turn on. Only the storage-management
software can detect the failure.
®
For example, the recovery procedure for a Predictive Failure Analysis
(PFA) flag
(impending drive failure) on a drive varies depending on the drive status (hot spare,
unassigned, RAID level, current logical drive status, and so on). Depending on the
circumstances, a PFA flag on a drive can indicate a high risk of data loss (if the
drive is in a RAID 0 volume) or a minimal risk (if the drive is unassigned). Only the
storage-management software can identify the risk level and provide the necessary
recovery procedures.
Note: For PFA flags, the General-system-error LED and Drive fault LEDs do not
turn on, so checking the LEDs will not notify you of the failure, even if the
risk of data loss is high.
Recovering from a storage-server failure might require you to perform procedures
other than replacing the component (such as backing up the logical drive or failing a
drive before removing it). The storage-management software gives these
procedures.
Attention: Not following the software-recovery procedures can result in data loss.
Checking the LEDs
The LEDs display the status of the storage server and components. Green LEDs
indicate a normal operating status; amber LEDs indicate a possible failure.
It is important to check all the LEDs on the front and back of the storage server
when you turn on the power. In addition to checking for faults, you can use the
LEDs on the front of the storage server to determine if the drives are responding to
I/O transmissions from the host.
For information about the LEDs on the front of the storage server, see:

Cache memory and RAID controller battery
Each RAID controller contains 128 MB of cache data. It also contains a
rechargeable battery that maintains data in the cache in the event of a power
failure. The following sections describe these features and their associated LEDs.
Cache memory
Cache memory is memory on the RAID controller that is used for intermediate
storage of read and write data. Using cache memory can increase system
performance. The data for a read operation from the host might be in the cache
memory from a previous operation (thus eliminating the need to access the drive
itself), and a write operation is completed when it is written to the cache, rather than
to the drives.
See the storage-management software documentation for information on setting
cache memory options.
The RAID controller has a Cache active LED that displays the current status of the
cache. The LED is on if there is data in the cache, and it is off if there is no data in
the cache.
If caching is enabled and the Cache active LED never comes on during I/O activity,
it indicates that the cache memory has failed or the battery has failed (the green
Battery LED will be off).
Note: Always use the storage-management software to check your cache memory
settings before assuming a hardware failure.
46 IBM TotalStorage FAStT600 Fibre Channel Storage Server: Installation and User’s Guide
Figure 38 shows the location of the Cache active LED on the front of the RAID
controller.
Figure 38. Cache active LED
RAID controller cache battery
Each RAID controller contains a sealed, rechargeable 4-volt lead-acid battery. This
battery provides cache backup for up to five days in the event of a power loss.
The service life of the battery is three years, after which time the battery must be
replaced. See the storage-management software for information on how to view and
set the battery expiration date.
Cache
active
LED
Each RAID controller has a green Battery LED on the back that indicates the
battery status, as follows:
v The LED is on and remains steady when the battery is fully charged.
v The LED flashes when the battery is charging or performing a self-test.
v The LED is off if the battery or the battery charger has failed.
The battery performs a self-test at startup and every 25 hours thereafter (during
which time the Battery LED flashes). If necessary, the battery begins recharging at
that time. If the battery fails the self-test, the Battery LED turns off, indicating a
battery fault.
Data caching starts after the battery completes the startup tests.

Chapter 5. Installing and replacing components
This chapter provides instructions to help you install or remove customer
replaceable units (CRUs), such as hot-swap drives, fans, RAID controllers, and
power supplies.
For more field-replaceable unit (FRU) and Option part number information, see the
following Web site:
www.ibm.com/storage/techsup.htm
Handling static-sensitive devices
Attention: Static electricity can damage electronic devices and your system. To
avoid damage, keep static-sensitive devices in their static-protective packages until
you are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following
precautions:
v Limit your movement. Movement can cause static electricity to build up around
you.
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed printed circuitry.
v Do not leave the device where others can handle and possibly damage the
device.
v While the device is still in its static-protective package, touch it to an unpainted
metal part of the storage server for at least two seconds. This drains static
electricity from the package and from your body.
v Remove the device from its package and install it directly into your storage
server without setting it down. If it is necessary to set the device down, place it in
its static-protective package. Do not place the device on your storage server
cover or any metal surface.
v Take additional care when handling devices during cold weather because heating
reduces indoor humidity and increases static electricity.
Working with hot-swap drives
Drives are devices that the system uses to store and retrieve data. This section
explains how you can increase the storage-server capacity by adding more drives
or replacing existing drives with ones containing a larger capacity.
Figure 40 on page 50 shows the location of the hot-swap drive bays that are
accessible from the front of the storage server. To maintain proper cooling within the
storage server, always keep a filler panel in each drive bay that does not contain a
drive CRU.
© Copyright IBM Corp. 2003 49
Hot-swap
drive CRU
Figure 40. Location of hot-swap drives
Attention: Never hot-swap a drive CRU when its green Activity LED is flashing.
Hot-swap a drive CRU only when its amber Fault LED is completely on and not
flashing or when the drive is inactive with the green Activity LED on and not
flashing.
Before you install or remove drive CRUs, review the following information:
Filler panels
Storage servers without a full set of drives (14) contain filler panels in the
unused drive bays. Before installing new drives, you must remove the filler
panels. Save the filler panels for future use. Each of the 14 bays must
always contain either a filler panel or a drive CRU.
Drive CRUs
The RAID controller supports up to 14 (half-high or slim) 40-pin
fibre-channel hard disk drives. These drives come preinstalled in drive trays.
This drive-and-tray assembly is called a drive CRU. You can install the drive
CRUs in the 14 drive bays on the front of the storage server.
Drive LEDs
Each drive CRU has two LEDs, which indicate the status for that particular
drive. For information about the drive LED operating states and
descriptions, see Figure 35 on page 43 and Table 10 on page 43.
Fibre-channel loop IDs
When you install a drive CRU in the storage server, the drive CRU
connects into a printed circuit board called the midplane. The midplane
automatically sets the fibre-channel loop ID to the default value 00.
Hot-swap hardware
The storage server contains hardware that you can use to replace a failed
hard disk drive without turning off the storage server. Therefore, you can
continue operating the system while a hard disk drive is removed or
installed. These drives are known as hot-swap drives.
Slim drives
You can install slim, hot-swap drive CRUs.
Installing hot-swap drives
Before you begin, take the following precautions:
v Read the safety and handling guidelines that are provided in “Safety” on page iii
and “Handling static-sensitive devices” on page 49.
v Ensure that the current system configuration is working properly.
v Back up all important data before you make changes to storage devices, such as
hard disk drives.
50 IBM TotalStorage FAStT600 Fibre Channel Storage Server: Installation and User’s Guide
Use the following procedure to install hot-swap drives in the storage server. You can
install additional drives while the storage server is powered up and running.
Note: If you are replacing a drive, see “Replacing hot-swap drives” on page 52.
1. Read the instructions that come with the drive CRU.
2. Check for Fault LEDs. If any amber LEDs are lit, see “Checking the LEDs” on
page 42 and “Troubleshooting” on page 74.
3. Determine the bay into which you want to install the drive.
4. Install the drive CRU:
Note: The hard disk drive comes with a tray already attached. Do not attempt
to detach the drive 4 from the tray 3. See Figure 41.
Figure 41. Releasing the drive latch
a. Release the blue latch 1 on the drive CRU by pressing on the inside of
the bottom of the tray handle. See Figure 41.
b. Pull the handle 2 on the tray out into the open position.
c. Slide the drive CRU into the empty bay until the tray handle 2 touches the
storage-server bezel.
d. Push the tray handle 2 down into the closed (latched) position.
5. Check the drive LEDs.
a. When a drive is ready for use, the green Activity LED is continuously on and
the amber Drive fault LED is off.
b. If the amber Drive fault LED is completely on and not flashing, remove the
drive from the unit and wait 10 seconds; then reinstall the drive.
6. Use the storage-management software to configure the drive.
7. Update the information in “Records”, on page 77.
Chapter 5. Installing and replacing components 51
Replacing hot-swap drives
Drive problems include any malfunctions that delay, interrupt, or prevent successful
I/O activity between the hosts and the hard disk drives. This includes transmission
problems between the host controllers, the RAID controllers, and the drives. This
section explains how to replace a failed drive.
Attention: Failure to replace the drives in their correct bays might result in loss of
data. If you are replacing a drive that is part of a RAID level 1 or RAID level 5
logical drive, ensure that you install the replacement drive in the correct bay.
Use the following procedure to replace host-swap drives:
1. Check the hardware and software documentation that is provided with the
system to see if there are restrictions regarding hard disk drive configurations.
Some system fibre-channel configurations might not allow mixing different drive
capacities or types within an array.
2. Check the storage-management software for recovery procedures for a drive
that has failed. Follow the steps in the software procedure before you continue
with this procedure.
3. Determine the location of the drive that you want to remove.
Attention: Never hot-swap a drive CRU when its green Activity LED is
flashing. Hot-swap a drive CRU only when its amber Drive fault LED is on and
not flashing or when the drive is inactive with the green Activity LED on and not
flashing.
4. Remove the drive CRU.
a. Press on the inside of the bottom of the tray handle to release the blue latch
1. See Figure 42.
b. Pull the handle 2 on the tray 3 out into the open position.
c. Lift the drive CRU partially out of the bay.
d. To avoid possible damage to the drive 4, wait at least 20 seconds before
you fully remove the drive CRU from the storage server to allow for the drive
to spin down.
Figure 42. Drive latch on a hot-swap drive
e. Verify that there is proper identification (such as a label) on the drive CRU,
and then slide it completely out of the storage server.
52 IBM TotalStorage FAStT600 Fibre Channel Storage Server: Installation and User’s Guide
5. Install the new drive CRU.
a. Gently push the drive CRU into the empty bay until the tray handle 2
touches the storage-server bezel.
b. Push the tray handle 2 down into the closed (latched) position.
6. Check the drive LEDs.
a. When a drive is ready for use, the green Activity LED is on, and the amber
Drive fault LED is off.
b. If the amber Drive fault LED is on and not flashing, remove the drive from
the unit and wait 10 seconds; then reinstall the drive.
7. Return to normal operation.
Upgrading drives
You can upgrade drives in the following two ways:
v By adding drives to empty slots in the storage server (see “Installing hot-swap
drives” on page 50)
v By replacing existing drives with larger capacity drives
Adding larger-capacity drives
This section provides guidelines for upgrading the drives in the storage server.
Read the software documentation and this entire section to determine if you should
use this procedure, use a modified version of this procedure, or use a different
procedure that is provided by your operating system. Instructions that are provided
with your software should supersede anything stated in this document.
There are two methods for upgrading drives:
v Replacing all the drives at the same time
This method requires that you back up the data on the affected drives and then
turn off the storage server. After replacing all the drives, you must reconfigure the
new drives and restore data from backup. See the procedure in “Replacing all
drives at the same time” on page 54.
This is the safest way to exchange drives without losing data. However, this
method might take a long time to complete because of the backup,
reconfiguration, and restoration processes. In addition, other users are not able
to use the storage server (or any expansion units attached to the storage server)
until you finish the procedure. You must use this method on RAID 0 logical
drives.
v Replacing the drives one at a time
In this method, you manually fail each drive, replace it, and wait for the system to
restore data to the new drive before installing the next drive. After you install the
new drives, you can configure them to make the additional drive space available.
See the procedure in “Replacing the drives one at a time” on page 56.
Using this method, you can replace the drives while the storage server is
running, eliminating the down time that is required if you replace all the drives at
once. However, this method is more risky because you can lose data if the drive
restoration or storage subsystem reconfiguration process fails. In addition, the
reconstruction process might take a long time. This method works only on
redundant logical drives (RAID 1, 3, or 5). You cannot use this method with any
drives containing RAID 0 logical drives.
Consider backing up your data if you use this method. This safeguards your data
if the restoration and reconfiguration process fails or the new drive malfunctions.
Chapter 5. Installing and replacing components 53
The method you use depends on the following considerations:
v Which method most closely matches the recommended drive upgrade procedure
that is provided in the operating system or the storage-management software
documentation
v Which RAID level is used on the affected drives (RAID 0 requires you to replace
all the drives at the same time)
v How much downtime is acceptable as you swap the drives
v The number of drives in an array. Replacing drives one at a time is better suited
for arrays consisting of 3 to 5 drives. If you have more than 20 drives, consider
replacing all drives at the same time.
Replacing all drives at the same time
Use this procedure to replace all drives at the same time. You must use this method
if you are upgrading drives containing RAID 0 logical drives. All the data currently
on the drives is lost when you replace the drives; therefore, you must back up all
data that is currently on the drives. This procedure also requires you to turn off the
storage server, which makes the storage server (and any attached expansion units)
inaccessible to other users.
To replace all the drives at the same time, perform the following steps:
1. Read the following information:
v The information in “Adding larger-capacity drives” on page 53, particularly
the paragraphs that discuss the differences between the two possible
upgrade procedures
v The information in your software documentation regarding drive upgrades
and installation
v The documentation that comes with the new drives
Read all precautionary notes, kit instructions, and other information. Kit
instructions often contain the most current information regarding the drives
and their installation, plus upgrade or servicing procedures. Compare the kit
instructions with this procedure to determine if you need to modify this
procedure.
2. Use the storage-management software to check the status of the storage
server. Correct any problems that are reported.
3. Perform a complete backup of the drives that you are replacing.
You need the backup to restore data on the drives later in this procedure.
Attention: When you handle static-sensitive devices, take precautions to
avoid damage from static electricity. For details about handling static-sensitive
devices, see “Handling static-sensitive devices” on page 49.
4. Unpack the new drives.
Set the drives on a dry, level surface away from magnetic fields. Save the
packing material and documentation in case you need to return the drives.
5. Perform the following steps:
a. Stop all I/O activity to the storage server and attached expansion units.
Make sure that:
1) All of the green Drive activity LEDs on the front of the storage server
(and on all attached expansion units) are not flashing.
2) The green Cache active LEDs are off on the front of the RAID
controllers.
54 IBM TotalStorage FAStT600 Fibre Channel Storage Server: Installation and User’s Guide
b. If applicable, use the operating system software to disconnect the storage
server logical drives from the host before you power off the storage server.
Attention: To turn off all power to the storage server, you must turn off both
power-supply switches and disconnect both power cords. Use the procedure in
step 6 for the proper shutdown sequence.
6. Turn off the power to each device based on the following shutdown sequence:
a. Turn off power to the host before you turn off power to the storage server.
If the host must stay powered on to support an existing network, see the
operating system documentation for information about disconnecting the
storage server logical drives from the host before the storage server is
powered off.
b. Turn off power to the storage server before you turn off power to the
expansion units. Turn off both power supply switches on the back of the
storage server.
c. Turn off power to other supporting devices (for example, management
stations, fibre-channel switches, or Ethernet switches).
Note: You do not need to perform this step if you are servicing only the
storage server.
7. Use the procedures in “Replacing hot-swap drives” on page 52 to remove the
drives that you want to replace. Use the procedures in “Installing hot-swap
drives” on page 50 to install the new drives into the storage server.
8. After you install all the new drives, check the system documentation for the
hardware devices that you intend to power up, and then determine the proper
startup sequence. Use the following power-on sequence, where applicable:
a. Turn on the power to the supporting devices (for example, Ethernet
switches and management stations) before you turn off power to the
storage server.
b. You must turn on the expansion units before the storage server. The
controllers might not recognize the correct configuration if the drives are
powered up after the storage server. For instructions on powering up the
expansion units, see the expansion-unit documentation.
c. Turn on the power to the storage server; then restart or turn on the power
to the host.
9. Turn on the power to each device, based on the power-on sequence in step 8.
To turn on power to the storage server, turn on the power-supply switches on
the back of the storage server. You must turn on both power-supply switches
to take advantage of the redundant power supplies.
10. Check the green Drive activity LED and the amber Drive fault LED below the
new drive CRUs.
Make sure that the Drive activity LEDs are on and the Drive fault LEDs are off.
Note: The Drive fault LEDs might flash intermittently while the drives spin up.
v If the Drive activity LED is off, the drive CRU might not be installed correctly.
v If the Drive fault LED stays on or the Drive activity LED stays off, the new
11. Use the storage-management software to configure the new drives. See the

drive might be faulty. See the storage-management software for problem
determination.
Chapter 5. Installing and replacing components 55
Replacing the drives one at a time
Use this procedure to replace all the drives one at a time. You cannot use this
procedure on RAID 0 logical drives (use the procedure in “Replacing all drives at
the same time” on page 54).
Note: If your storage subsystem has hot spares assigned, you might want to
unassign the hot spares while you perform this procedure. If you do not,
reconstruction might start on the hot spare before you insert the new drive.
The data on the new drive is still rebuilt, but the process takes longer for
each drive. Remember to reassign the hot spares when you are finished with
this procedure.
To replace the drives one at a time, perform the following steps:
1. Read the following information:
v “Adding larger-capacity drives” on page 53, particularly the paragraphs that
discuss the differences between the two possible upgrade procedures
v Your software documentation regarding drive upgrades and installation
v The documentation that comes with the new drives
Read all precautionary notes, kit instructions, and other information. Kit
instructions often contain the most current information regarding the drives
and their installation, plus upgrade or servicing procedures. Compare the kit
instructions with this procedure to determine if you need to modify this
procedure.
2. Use the storage-management software to check the status of the unit. Correct
any problems that are reported.
3. Back up the data on the drives that you are replacing.
Attention: When you handle static-sensitive devices, take precautions to
avoid damage from static electricity. For details about handling static-sensitive
devices, see “Handling static-sensitive devices” on page 49.
4. Unpack the new drives.
Set the drives on a dry, level surface away from magnetic fields. Save the
packing material and documentation in case you need to return the drives.
5. Use the storage management software to ensure that the array that was
defined using these drives is in optimal (not degraded) state before manually
failing the first drive you want to replace. If the array is in degraded state, use
the recovery procedures to bring the array into the optimal state.
Make sure that:
v You fail only one drive
v The software status display shows a failed status for the appropriate drive
v The amber Drive fault LED (on the front bezel below the drive) is on
Attention: Removing the wrong drive can cause data loss. Make sure that
you remove only the failed drive CRU. The Drive fault LED below the failed
drive CRU should be on.
If you remove an active drive accidentally, wait at least 30 seconds and then
reinstall it. Because you failed two drives in a RAID array, the array might be
marked failed by the controller. This array will not be available to the host for
I/O. See the storage-management software for further recovery instructions. Do
not attempt to replace any drives until the array is brought back to optimal
state.
56 IBM TotalStorage FAStT600 Fibre Channel Storage Server: Installation and User’s Guide
6. Use the procedures in “Replacing hot-swap drives” on page 52 to remove the
failed drive. Use the procedures in “Installing hot-swap drives” on page 50 to
install the new drives into the storage server.
The new drive automatically reconstructs the data after you install it in the
drive slot.
During data reconstruction, the amber Drive fault LED might come on for a few
minutes, then turn off when the green Drive activity LED begins flashing. A
flashing Drive activity LED indicates that data reconstruction is in progress.
Note: If your storage subsystem has active hot spares, data might not start
copying to the new drive until the data is reconstructed on the hot
spare. This increases the time that is required to complete the
procedure.
7. Check the green Drive activity LED and the amber Drive fault LED below the
new drive CRUs.
Make sure that the Drive activity LEDs are on and the Drive fault LEDs are off.
Note: The Drive fault LEDs might flash intermittently while the drives spin up.
v If the Drive activity LED is off, the drive CRU might not be installed correctly.
Remove the drive CRU, wait 30 seconds, and then reinstall it.
v If the Drive fault LED stays on or the Drive activity LED stays off, the new
drive might be faulty. See the storage-management software for problem
determination.
8. Use the storage-management software to monitor the status of the new drive
and the progress of the data reconstruction. Wait for data reconstruction to
finish (the Drive activity LED stops flashing).
Note: The Drive activity LED will continue to flash after reconstruction is
finished if there is I/O activity to that drive. In that case, use the host
software to determine if the data reconstruction is finished.
9. When reconstruction is finished on the new drive, repeat step 5 on page 56
through step 8 for each additional drive that you want to install.
10. Use the storage-management software to configure the additional space on the
new drives.
Working with hot-swap cooling fans
The storage server cooling system consists of two fan CRUs, each containing two
fans. The fan CRUs circulate air inside the unit by pulling in air through the vents
on the front of the drive CRUs and pushing out air through the vents in the back of
each fan CRU. See Figure 43 on page 58.
If two fans fail, or the fans cannot maintain an internal temperature below 70°C
(158°F), the power supplies in the unit will automatically shut down (an
over-temperature condition). If this occurs, you must cool the unit and restart it. See
“Restoring power after an over-temperature shutdown” on page 41.
Attention: The fans in the storage server draw in fresh air and force out hot air.
These fans are hot-swappable and redundant; however, when one fan fails, you
must replace the fan CRU within 48 hours to maintain redundancy and optimum
cooling. When you replace the failed fan CRU, be sure to install the second fan
CRU within 10 minutes to prevent any overheating due to the lack of the additional
fan CRU.

Latches and handles
Use the latches and handles to remove or install the fan CRUs.
Attention: Do not run the storage server without adequate ventilation and cooling,
because it might cause damage to the internal components and circuitry.
Both fan units must always be in place, even if one is not functioning properly, to
maintain proper cooling.
Use the following procedure to replace a hot-swap fan:
1. Check the LEDs on the back of the storage server.
2. If the amber Fault LED is on, remove the fan CRU that has failed.
a. Slide the latch to unlock the fan CRU.
b. Use the handle (black knob) to pull the fan from the storage server. See
Figure 44.
Figure 44. Removing a fan
3. Install the new fan unit.
a. Place the fan CRU in front of the fan slot.
58 IBM TotalStorage FAStT600 Fibre Channel Storage Server: Installation and User’s Guide
b. Hold the latch open, and slide the fan all the way into the slot. If the fan
does not go into the bay, rotate it 180°. Ensure that the latch is on the side
closest to the center of the storage server.
c. Release the latch. If the lever remains open, pull back on the fan slightly,
and then push it in again until the latch snaps into place.
4. Check the LEDs.
The Fault LEDs turn off after a few seconds. If they remain on, see
“Troubleshooting” on page 74.
Working with hot-swap power supplies
The storage server power system consists of two power supply CRUs. The power
supply CRUs provide power to the internal components by converting incoming ac
voltage to dc voltage. One power supply CRU can maintain electrical power to the
unit if the other power supply is turned off or malfunctions. The power supply CRUs
are interchangeable (by reversing the locking levers).
Each power supply CRU has a built-in sensor that detects the following conditions:
v Over-voltage
v Over-current
v Overheated power supply
If any of these conditions occurs, one or both power supplies will shut down. All
power remains off until you cycle the power switches (turn the power switches off,
wait at least 30 seconds, then turn the power switches on). For more information,
see “Restoring power after an unexpected shutdown” on page 40 and “Restoring
power after an over-temperature shutdown” on page 41.
The power supplies are customer replaceable units (CRUs) and do not require
preventive maintenance.
v Always keep the power supplies in their proper places to maintain proper
controller-unit cooling.
v Use only the supported power supplies for your specific storage server.
The power-supply controls on the rear of the storage server are shown in Figure 45
on page 60.

Working with hot-swap RAID controllers
Each RAID controller fits into the back of the storage server and has the following
components:
v Battery
v Cache memory
v Two host ports and one expansion port
v One Ethernet port
v One serial port
Each RAID controller has a unique hardware Ethernet address, which is printed on
a label on the front. There is also a label giving the cache battery manufacturing
and installation dates on the top of the controller unit. Figure 49 on page 64 shows
the location of these items.

Important: The replacement RAID controller CRU does not come with a RAID
controller cache battery installed, nor the mounting hardware that holds
the battery in place inside the RAID controller. You must remove the
cache battery that is inside the existing RAID controller that you are
replacing, and install that battery inside the replacement RAID controller
CRU, using the battery unit mounting hardware taken from the existing
controller. The steps to remove and replace the battery are included in
the following procedure.
To replace a RAID controller, perform the following steps:
1. Check the storage-management software for instructions on RAID controller
failure-recovery procedures. Follow the steps provided in the software
documentation before continuing with step 2.
2. Label each cable that connects to the RAID controller that has failed. This
ensures that all cables will be properly reconnected to the new RAID controller.
Attention: Handle and install fiber-optic cables properly to avoid degraded
performance or loss of communications with devices. When working with
fiber-optic cables, do not pinch them, step on them, or locate them in aisles or
walkways. Do not overtighten the cable straps or bend the cables to a radius
smaller than 38 mm (1.5 in.).
3. From the RAID controller that has failed, remove the fibre-channel cables from
the SFPs. The location of these components is shown in Figure 50 on page 65.

Replacing the battery in the RAID controller
Each RAID controller contains a rechargeable battery that maintains the data in the
cache memory for three days without power to the unit.
Use the following procedure if the storage-management software instructs you to
replace the battery because the current battery has failed or is nearing its expiration
date. You can also use the storage-management software to check the status of the
battery.
1. Check the storage-management software for instructions on battery
replacement procedures. If you are not using write-cache mirroring, this might
involve clearing cache memory on the RAID controller that contains the battery
that has failed. This is done by either placing the controller offline before
removing it from the FAStT600 server or turning off caching in the FAStT600
server, using storage-management software. Follow the steps given in the
software procedure before you continue with this procedure.
Attention: When you handle static-sensitive devices, take precautions to
avoid damage from static electricity. For details about handling static-sensitive
devices, see “Handling static-sensitive devices” on page 49.
2. Unpack the new battery.
Set the new battery on a dry, level surface. Save all packing materials in case
you need to return the battery.
Note: The battery comes with a new battery label. You will need this label
later in the procedure.
3. Review all documentation that comes with the new battery for updated
replacement procedures and other information.
4. Use the storage-management software to locate the RAID controller that
contains the failed battery (the RAID controller Fault LED might be on).
5. Label each cable that connects to the RAID controller that contains the battery
that has failed. This ensures that all cables will be properly reconnected to the
RAID controller after you replace the battery.
6. Use the storage management software to take offline the RAID controller that
contains the battery that has failed.
Attention: To prevent data loss, you must shutdown the system before you
can replace the RAID controller battery. For the proper shutdown sequence,
see “Turning off the storage server” on page 39.
7. Remove the fibre-channel cables and the SFPs from the RAID controller that
contains the battery that has failed or is nearing its expiration date. For more
information, see “Working with SFPs and fiber-optic cables” on page 27.
8. Remove the RAID controller as described in “Replacing a RAID controller” on
page 64.
