Chapter 1. Introduction
This chapter describes the operating specifications, features, and components for
the IBM TotalStorage Fibre Array Storage Technology (FAStT) FAStT100 storage
server (hereafter referred to as FAStT100 or storage server). This chapter also
includes a list of hardware that comes with the storage server.
Overview
IBM FAStT 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.
The FAStT100 (Machine Type 1724, Model 100) is a rack-mountable storage server
that 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 FAStT100 is designed to provide
maximum host and drive-side redundancy. Each RAID controller supports direct
attachment of one host that contains one or two host adapters.
Designed for data archival, data reference, and near-line storage applications, the
FAStT100 utilizes the latest Serial Advanced Technology Attachment (SATA) disk
drive technology. The FAStT100 supports up to fourteen 1.5 Gbps 250 GB SATA
disk drive modules, offering up to 3.5 terabytes (TB) of capacity per enclosure. You
can configure RAID-protected storage solutions of up to 14 TB, providing
economical and scalable storage for your rapidly growing application needs for
limited access, data reference storage capacity. The FAStT100 is designed with
redundant 2 Gbps fibre channel connections for expanding the FAStT100 storage
capacity to SATA hard drives in external EXP100 drive expansion enclosures.
The FAStT100 supports redundant configurations with FAStT EXP100 expansion
units. External cables and small form-factor pluggable (SFP) modules connect the
storage server to the expansion unit. The FAStT100 can be used in storage area
networks to satisfy the needs of various fixed content, data reference applications
that require large amounts of storage capacity but do not have the high utilization
and access characteristics satisfied by fibre channel disk drive storage. The storage
server provides continuous, reliable service, using hot-swap technology for easy
replacement without shutting down the system. Up to three FAStT EXP100 units
can be connected together with the FAStT100 in a fibre-channel loop, providing
connections to a maximum of 56 hard drives. Contact your IBM support
representative for information about the availability of future support for connecting
more than three FAStT EXP100 units.
Note: SATA hard drive CRUs cannot be interchanged with the fibre-channel hard
drive CRUs that are supported in other FAStT storage products.

Attention
ensure proper operation when connecting EXP100 expansion units to the
FAStT100, you must verify that the EXP100 ESM firmware level is at level
9551 or later. If the ESM firmware level is lower than 9551, disconnect the
EXP100 and contact IBM support, your IBM reseller, or your IBM
representative for assistance. See the IBM TotalStorage FAStT EXP100
Expansion Unit Installation and User′s Guide for details on how to determine
ESM firmware versions.
Fibre channel defined
Fibre channel technology is outlined in the SCSI-3 Fibre Channel Protocol
(SCSI-FCP) standard. Fibre channel is a high-speed data transport technology that
used for mass storage and networking.
Using a fibre-channel arbitrated loop (FC-AL), more than 100 fibre-channel devices
can be supported, compared to 15 small computer system interface (SCSI) devices.
The connection from the FAStT100 to the FAStT EXP100 is a 2 Gb fibre-channel
device that supports data transfer rates up to 200 MBps half-duplex and 400 MBps
full-duplex on optical interfaces.
SATA defined
The Serial Advanced Technology Attachment (SATA) interface offers increased data
rate performance over Parallel Advanced Technology Attachment (ATA), while
maintaining the benefits of ATA. SATA is designed to overcome the performance
barriers that have been forecasted for current parallel technologies while
maintaining the cost-efficiency of Parallel ATA. SATA specifications allow for thinner,
more flexible cables, and lower pin counts. It also enables easier, more flexible
cable routing management and the use of smaller connectors than is possible with
the existing Parallel ATA technology.
The Serial ATA Working Group introduced the first SATA specification, Serial ATA
1.0, in 2001 (http://www.serialata.org).
Product updates
You should download the latest version of the FAStT Storage Manager host
software and the FAStT storage server controller firmware (and, if you are
connecting EXP100 expansion units to the FAStT100 storage server, the EXP100
ESM firmware and the EXP100 disk drive firmware) at the time of the initial
installation and when product updates become available.
1
notified of important product updates, you must first register at the IBM
Support and Download Web site:
www.ibm.com/servers/storage/support/fastt
1. For the FAStT100, each drive is considered to be a device in a fibre-channel loop, even though the FAStT100 drive interface is
SATA (not fibre channel). The EXP100 ESM and the FAStT100 controller and SATA hard drive interposer convert SATA interface
protocol to fibre channel protocol.

maintain power redundancy, plug the 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 FAStT100
should be plugged into the same two independent external power circuits as the
FAStT100. This ensures that the FAStT100 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 enables the
components in the storage subsystem to power on simultaneously during an
unattended restoration of power. See Figure 47 on page 52 for an example of
redundant power connections.
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.
Ensure that your system is in an optimal state before you shut it 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.
During any maintenance or attended power-up procedure, carefully follow the
power-up sequence listed in “Turning on the storage server” on page 57. Check
that each component of the subsystem 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.
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 57 during any attended power-up
procedure.
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 you
remove, install, or replace a hot-swap device.
Hot-swap drive bays
The hot-swap drive bays that are accessible from the front of your storage server
are shown in Figure 2 on page 6.

Figure 2. FAStT100 hot-swap drive bays
The FAStT100 supports up to 14 FAStT 1.5 Gbps SATA hard disk drives. These
drives are preinstalled in drive trays. The unit consisting of the drive and the drive
carrier assembly is called a drive CRU. The SATA drive CRU includes the drive tray,
the SATA drive, and the hard disk drive (HDD) interposer card. You install the drive
CRUs in the 14 drive bays on the front of the storage server. There are no
serviceable parts in a drive CRU. If it fails, it must be replaced in its entirety (drive,
interposer, bezel, and tray).
Attention:
Never hot-swap a drive CRU when its associated green Activity LED is flashing.
Hot-swap a drive CRU only when its associated amber Fault LED lights and is
not flashing or when the drive is inactive and its associated green Activity LED
lights and is not flashing.
The SATA drive and its HDD card are digitally signed together at the factory. Do
not swap drives and interposers between drive CRUs. Do not replace one SATA
drive with another SATA drive. These actions will result in a drive CRU that
cannot be recognized by the storage server RAID controller.
Note:
the hard disk drive you want to remove is not in a failed or bypass state,
always use the Storage Manager client program either to place the drive in a
failed state or to place the array that is associated with the drive (or drives)
offline state before you remove the drive from the enclosure.

Each RAID controller contains three ports for Small Form-Factor Pluggable
(SFP) modules that connect to the fibre channel cables. Two of the SFP
ports (labelled Host 1 and Host 2) are for host server attachment. The third
SFP port (labeled Expansion) is used to connect additional expansion units
the storage server.
Each RAID controller also contains a battery to maintain cache data in the
event of a power failure. For more information, see “Cache memory and
RAID controller battery” on page 66.
Hot-swap fans
The storage server has two interchangeable hot-swap and redundant fan
CRUs. Each fan CRU contains two fans. If one fan CRU fails, the second
fan CRU continues to operate. You must install both fan CRUs to maintain
proper cooling within the storage server, even if one fan CRU is not
operational.

Substantial deviations from the suggested operating range, in either direction, if
sustained for extended periods of time, will expose the unit to greater risk of
failure from external causes.
Heat output, airflow, and cooling
The maximum heat output of the FAStT100 is 390 watts (1088 BTU/hr). Each
FAStT100 rack-mounted unit requires an airflow of 2.5 m
input air temperature to all racks should be in the range 10° C - 35° C (50° F - 95°
F). The recommended operating temperature is 22° C (72° F).
When racks that contain many FAStT100s are to be installed together, the following
requirements must be met to ensure that the FAStT100s are adequately cooled:
Air enters at the front of the rack and leaves at the back. To prevent the air that
leaving the rack from entering the intake of another piece of equipment, you
must position the racks in alternate rows, back-to-back and front-to-front. This
arrangement is known as “cold aisle/hot aisle” and is shown in Figure 6 on page
12.
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 storage servers that are in that rack. You should use Suite
Attach Kits to completely seal any gaps that remain between the racks. For
details about Suite Attach Kits, contact your marketing representative.
Where racks are in rows front-to-front or back-to-back, a gap of at least 1220 mm
(48 in.) must separate the rows across the cold aisle.

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.
reduce the possibility of electrostatic discharge, observe the following
precautions:
Limit your movement. Movement can cause static electricity to build up around
you.
Handle the device carefully, holding it by its edges or its frame.
not touch solder joints, pins, or exposed printed circuitry.
not leave the device where others can handle and possibly damage the
device.
While the device is still in its static-protective package, touch it to an unpainted
metal part of the system unit for at least two seconds. This drains static electricity
from the package and from your body.
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
metal table. Take additional care when handling devices during cold weather
because heating reduces indoor humidity and increases static electricity.
Preparing for installation
Complete the following steps to prepare the FAStT100 for installation into a rack
cabinet.
Prepare the site to meet all area, environmental, power, and site requirements.

Installing the support rails
Before installing the FAStT100 in a rack, you must install the rails and
rack-mounting hardware that come with your storage server. The FAStT100 requires
Electronic Industries Association (EIA) 310-D Type A 19-inch rack cabinet. The
distance between EIA rails, from the front to the rear of the rack, is 60.96 cm (24
in.) minimum and 81.28 cm (32 in.) maximum. This rack conforms to the EIA
standard. Where you place the support rails in the rack depends on where you
intend to position the storage server.
Complete the following steps to install the support rails:
Note: Refer to Figure 10 on page 20 while performing these steps.
Ensure that the rack has already been installed.
Ensure that a stabilizer has been correctly attached to the bottom front of the
rack to prevent the rack from tipping forward while the FAStT100 is being

and Figure 8 on page 18 to locate the proper rack mounting holes for installing
the support rails into the rack.
Note the following considerations before you choose where to install the rails:
you are installing the FAStT100 into an empty rack, install it into the
lowest available position so that the rack does not become unstable.
you are installing more than one FAStT100 in the rack, start at the lowest
available position, and work upward.
appropriate, allow for possible later installation of other units.
necessary, remove the rack power distribution unit before you install the
support rails.
For procedures and more information, refer to the installation and service
guide, or equivalent, for the rack.

Starting with the left rail, remove and save the 6/32 in. screw (5). Loosen the
four rail adjustment screws (2).
Note:
The support rails are not marked as Left or Right. However, each rail
can be correctly mounted on only one side of the rack cabinet. The rails
should be mounted with the alignment pins at the front of the rack.
Figure 10 shows the installation of the left support rail.
Hold the front of the rail against the inside of the right rack-mounting flange
and loosely tighten the lower M6 screw (4). See Figure 7 on page 17 for the
location for this screw.
Extend the rear of the support rail until it makes contact with the rear rack rail.
From the rear of the rack, thread and tighten two M6 screws (1) (see
Figure 8 on page 18 for the location for these screws). From the front of the
rack, finish tightening the front M6 screw (4).
When you are the finished, the rail should be attached to the cabinet using one
screw in the front (inserted at the second-to-lowest hole) and two M6
screws at the back.

Continue with “Removing the CRUs.”
Removing the CRUs
Attention: This section describes how to remove the CRUs in order to minimize
the weight of the FAStT100 before you install it in the rack. However, if you have
three or more people available to lift and install the FAStT100 in a rack, you might
not find it necessary to remove the CRUs before you install the FAStT100. If this is
the case, you can skip the CRU removal instructions provided in this section.
Instead, continue with “Installing the FAStT100 into a rack” on page 24, and then
skip the CRU replacement instructions provided in “Replacing the FAStT100 CRUs”

Use the following procedures to remove the CRUs from the FAStT100 before
installation. Use these instructions after you have completed all applicable site,
rack, and FAStT100 preparations (as discussed in “Preparing for installation” on
page 14) and installed the support rails (as discussed in “Installing the support rails”
page 18). Alternately, if necessary, you can use these instructions to lighten the
FAStT100 before removing it from the shipping box. The shipping box opens to
provide access to the storage server CRUs.
The FAStT100 comes with a rack-mounting hardware kit for installing it in a rack. It
easier to lift the FAStT100 and install it in a rack cabinet if you remove all the
CRUs first. You will need an antistatic wrist strap and a cart or level surface (to hold
the CRUs). Observe the precautions listed in “Handling static-sensitive devices” on
page 14. In the following procedure, you will remove the following CRUs from the
storage server before you install it in the rack:

When you install a hard disk drive in the storage server, the drive tray plugs into a
printed circuit board called the midplane. The midplane sets the fibre-channel loop
automatically, based on the server ID switch setting and the physical location
(bay) of the hard disk drive.
Server ID (Enclosure ID) settings
The FAStT100 comes with a server ID switch (also referred to as an enclosure ID
switch) that is used to identify the FAStT100 on a fibre channel loop. The server ID
switch is located on the back of the unit, as shown in Figure 21 on page 30.
Chapter 2. Installing the storage server
29
Page 60
30
Server ID Switch
Figure 21. Setting the Server ID
Each drive enclosure in a FAStT storage subsystem drive loop must have a unique
drive enclosure ID. FAStT controllers use a combination of the enclosure ID and the
number of the physical slot that a fibre channel hard drive occupies to create a
unique fibre channel loop address or arbitrated loop physical address (AL_PA) for
each drive in a fibre channel drive loop. The enclosure ID consists of two digits, a
tens digit (x10) and ones digit (x1).
Attention: When connecting the FAStT100 to EXP100 drive enclosures, DO NOT
use the tens digit (x10) setting. Use only the ones digit (x1) setting to set unique
server IDs or enclosure IDs.
Give each drive expansion enclosure in a redundant drive loop a unique ones digit
(x1) ID. This setting will enforce hard AL_PAs (unchangeable between fibre channel
Loop Initializations [LIPs]) for the drives and facilitate drive loop problem
troubleshooting in the event of an error. If the ones digits are not unique, two or
more devices will have the same hard AL_PA. In such a case, the controller will use
soft AL_PAs for the devices that have identical hard AL_PAs.
The problem with soft addressing is that addresses may change between LIPs. This
possibility increases the difficulty of troubleshooting drive loop problems, since one
cannot easily ascertain whether the same device with a different address or
different device may be causing a problem.
f10ug062
Note: The FAStT100 is shipped with 00 as the default server ID setting. If you
connect the storage server to a FAStT EXP100, you must set the EXP100
enclosure ID setting to a value other than 00. 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 another unit in the drive loop has the same ID setting as the server ID.
Storage server speed settings
The default switch setting is 2 Gbps. This is the only speed setting allowed for the
FAStT100.
Attention: Do not remove the metal plate that covers the storage server speed
setting. Do not adjust the storage server speed setting.
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
either of two ways: host-agent management or direct-management.
Important:
the operating system of the host server that the storage subsystem
logical drive(s) is mapped to is not Microsoft Windows NT, you have to
make an out-of-band direct management connection to the storage
subsystem to set the correct host type first. Then, the server will be
able to recognize the storage subsystem correctly for in-band
management.
Host-agent management method
This method requires host-agent software that you install on the host server. The
host-agent software allows the FAStT storage manager client program to manage
the FAStT storage subsystem using the same fibre channel connections between
the host server and the storage subsystem. 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 22 on page 32 shows the host-agent
management method.

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 23 on page 33

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 FAStT100 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 fiber-optic cables
connect one expansion unit to another in a daisy-chain. For more information
about adding expansion units, see “Connecting expansion units” on page 53.
f10ug008
Management station
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 fibre channel storage server through switches.
The illustrations in the following sections show common host system configurations.

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 57 for the initial startup
the storage server.
Working with SFPs and fiber-optic cables
Each RAID controller has two host ports and one expansion port. You use a
small-form factor pluggable transceiver (SFP) 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:
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.
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 you use fiber-optic cables, read the following precautions.
Copyright IBM Corp. 2004
Attention: To avoid damage to the fiber-optic cables, follow these guidelines:
not route the cable along a folding cable-management arm.
When attaching to a device on slide rails, leave enough slack in the cable so that
does not bend to a radius of less than 38 mm (1.5 in.) when extended or
become pinched when retracted.
Route the cable away from places where it can be snagged by other devices in
the rack.

not overtighten the cable straps or bend the cables to a radius of less than 38
(1.5 in.).
not put excess weight on the cable at the connection point. Be sure that the
cable is well supported.
Installing SFP modules
The FAStT100 host ports require 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 FAStT100 supports two types of SFP modules: one
with a plastic latch and one with a wire latch. After you install the SFP modules, you
use fiber-optic cables to connect the FAStT100 to other fibre channel devices.
Before you install SFP modules and fiber-optic cables, read the following
information:
not mix long-wave SFPs and short-wave SFPs on a single storage server.
Use either long-wave SFPs or short-wave SFPs. You can use the Storage
Manager client to view the Storage Subsystem Profile in order to verify that you
are not mixing long-wave and short-wave SFPs.
The SFP module housing has an integral guide key designed to prevent you from
inserting the SFP module improperly.
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.
You can insert or remove the SFP module while the port is powered on.
The operational loop performance is not affected when you install or remove an
SFP module.
You must insert the SFP module into a port before you connect the fiber-optic
cable.
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 42 for
more information.

for the RAID controllers. Use your operating system documentation to make the
new logical drives accessible to the operating system.
Important: Controller firmware version 5.42.xx.xx is required for the FAStT100.
However, this version of the controller firmware should be used only for
the FAStT100. Do not use controller firmware version 5.42.xx.xx for any
FAStT storage servers other than the FAStT100.

Connecting expansion units
Attention: The minimum EXP100 ESM firmware level (9551 or later) is required
before attaching an EXP100 to the FAStT100.
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.
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 FAStT100 storage server, you must contact IBM for information. Improper drive
migration might cause loss of configuration and other storage server problems.
connect a single additional expansion unit to the storage server, perform the
following steps:
Note:
The following procedures are for ″cold-case″ procedures (the FAStT100 is
powered down when expansion units are connected, as in the case of a new
installation). For ″hot-case″ procedures (the FAStT100 is powered on when
expansion units are connected), see “Adding a FAStT EXP100 to an existing
FAStT100 configuration” on page 91.
Follow the instructions in your expansion unit installation manual to set up and
mount the new expansion unit.
Use the following procedure and Figure 48 on page 54 to connect a single
expansion unit to the storage server:
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.
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.
Ensure that the enclosure ID switch is set to a value different from one set
for the FAStT100 server and other drive expansion enclosures in the loop.
Also, ensure that the link speeds of the expansion units are set to 2 Gb.
Note: When connecting the FAStT100 to EXP100 drive enclosures, do not
use the tens digit (x10) setting. Use only the ones digit (x1) setting to
set unique server IDs or enclosure IDs. For more information, see
“Server ID (Enclosure ID) settings” on page 29.

Remove the blank filler trays and insert drive trays. Connect power to the drive
expansion unit first, then connect power to the FAStT100. After the storage
server is powered-on, the storage server locates the new drives.
Use the Storage Manager client to check the status of the new drives, correct
any errors found, and configure the new drives.
For more detailed information about how to cable the storage server and expansion
units, see the FAStT100 Fibre Channel Cabling Instructions that come with the
storage server.
FAStT EXP100 loop redundancy
The FAStT EXP100 provides redundant loop support when the second ESM is
configured, and when both loops (called A and B) are connected to a FAStT storage
server that supports redundant loops. If a cable or SFP module fails on drive loop
drive loop B provides redundancy, which is an alternate path to your disk drives.
Figure 49 on page 55 shows a redundant loop that you might create with a
FAStT100 and three FAStT EXP100s. The numbers provided in Figure 49 on page
show the order in which cables should be attached.

Figure 49. FAStT EXP100 redundant loop configuration
To create the redundant loop shown in Figure 49, you would perform the following
steps:
Make two fibre-channel connections from the First expansion unit to the Second
expansion unit (connections 1 and 2).
Make two fibre-channel connections from the Second expansion unit to the Last
expansion unit (connections 3 and 4). Currently, you can connect up to three
FAStT EXP100s together in a redundant drive loop. Contact your IBM support
representative for information about the availability of future support for
connecting more than three FAStT EXP100 units.
Make a fibre-channel connection from the storage server drive port to the OUT
port in the left ESM of the First expansion unit in the redundant drive loop
(connection 5).
Make a fibre-channel connection from the storage server drive port to the IN
port in the right ESM of the Last expansion unit in the redundant drive loop
(connection 6).
IBM SATA disk drives are dual-ported, providing individual access from two
fibre-channel loops to the same disk drive. When configuring the ESMs, configure
the second ESM the same way that you configured the first ESM. Refer to the Fibre
Channel Cabling Instructions that come with your storage server for more
information about dual-loop support and implementation.
Each ESM on the EXP100 has an SFP module input port and an SFP module
output port. As you cable FAStT EXP100s together, connecting input ports to output
ports can improve diagnostic capability. Refer to the FAStT100 Storage Server Fibre
Channel Cabling Instructions for cabling connections between input and output
ports.

maintain power redundancy, plug the 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 FAStT100
should be plugged into the same two independent external power circuits as the
FAStT100 . This ensures that the FAStT100 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 47 on page 52 for an example of
redundant power connections.
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.
Ensure that your system is in an optimal state before you shut it 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.
During any maintenance or attended power-up procedure, carefully follow the
power-up sequence listed in “Turning on the storage server.” You should check
that each component of the subsystem is powered-on in the proper order during
this entire power-up procedure to ensure that the controller will optimally access
all of your storage subsystems.
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” during any attended power-up procedure.

the correct configuration if the hard disk drives are powered up after the
FAStT100. For instructions on how to power 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.
Perform the following steps to turn on the power for the initial startup of the storage
server:
Verify that:
All communication and power cables are plugged into the back of the
storage server and a properly grounded ac electrical outlet.
All hard disk drives are locked securely in place. For more information, see
“Installing hot-swap hard disk drives” on page 70.
Note: At least one drive must be present before you start the FAStT100.
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
step 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:
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
the Dynamic Host Configuration Protocol (DHCP) or BOOT-P server
before you turn 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.
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 how to power up
the expansion units, see the expansion-unit documentation.
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
the host. For more information, see the software installation guide for
your operating system.
Turn on the power to each device, based on the power-on sequence in step 2.

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:
The internal temperature of the storage server exceeds the maximum operating
temperature (an over-temperature condition).
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 Manager client 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

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 Chapter 6,
“Hardware maintenance,” on page 95).
Use this procedure to shut down the storage server during an emergency:
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.
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.
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:
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.
After you have checked for damage, ensure that the power-supply switches are
off; then plug in the storage-server power cords.
Complete step 2 on page 58 to determine the proper power-on sequence for
your system.
Complete steps 3 and 4 on page 58 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
over-temperature condition:
Make sure that the power-supply switches on the back of the storage server are
turned off.
whatever is necessary to cool the unit (replace the fans, use external fans to
cool the room, and so on).
Check all components and cables for visible damage. Do not start the storage
server if you find evidence of damage.
Complete step 2 on page 58 to determine the proper power-on sequence for
your system.
When the internal temperature of the storage server is below 35°C (95°F),
complete steps 3 and 4 on page 58 to turn on power to the devices in your
system and to check the status of the storage server.

Monitoring status through software
Attention
ensure proper operation when connecting EXP100 expansion units to the
FAStT100, you must verify that the EXP100 ESM firmware level is at level
9551 or later. If the ESM firmware level is lower than 9551, disconnect the
EXP100 and contact IBM support, your IBM reseller, or your IBM
representative for assistance. See the IBM TotalStorage FAStT EXP100
Expansion Unit Installation and User′s Guide for details on how to determine
ESM firmware versions.
Use the Storage Manager client to monitor the status of the storage server. Run the
software constantly, and check it frequently.
Important:
Refer to the IBM TotalStorage FAStT Storage Manager 8.42 Installation
and Support Guide for the appropriate operating system for instructions
how to install the FAStT Storage Manager 8.42.xx.xx host software.
addition, to download the latest version of the FAStT Storage
Manager 8.42.xx.xx host software, the FAStT storage server controller
firmware and NVSRAM 5.42.xx.xx, and the latest FAStT EXP100 R2
ESM firmware (version 955x or higher), go to the following Web site:
www.ibm.com/storage/support/fastt
The Storage Manager client provides the best way to diagnose and repair
storage-server failures. The software can help you:
Determine the nature of the failure
Locate the failed component
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 Manager client 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 Manager client 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 Manager client gives these procedures.

Cache memory and RAID controller battery
Each RAID controller in the FAStT100 contains 128 MB of cache data. Each
controller 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
the drives.

See the Storage Manager client 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.
caching is enabled and the Cache active LED never comes on during I/O activity,
indicates that the cache memory has failed or the battery has failed (the green
Battery LED will be off).
Note: Always use the Storage Manager client to check your cache memory
settings before assuming a hardware failure.
Figure 53 shows the location of the Cache active LED on the front of the RAID
controller.
Figure 53. 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 three 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 Manager client for information on how to view and set
the battery expiration date.
Each RAID controller has a green Battery LED on the back that indicates the
battery status, as follows:
The LED is on and remains steady when the battery is fully charged.
The LED flashes when the battery is charging or performing a self-test.
The LED is off if the battery or the battery charger has failed.

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. This chapter also provides instructions to help you add new
EXP100 expansion units to existing FAStT100 configuration.
For more field-replaceable unit (FRU) and Option part number information, see the

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.
reduce the possibility of electrostatic discharge, observe the following
precautions:
Limit your movement. Movement can cause static electricity to build up around
you.
Handle the device carefully, holding it by its edges or its frame.
not touch solder joints, pins, or exposed printed circuitry.
not leave the device where others can handle and possibly damage the
device.
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.
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.
Take additional care when handling devices during cold weather because heating
reduces indoor humidity and increases static electricity.
Working with hot-swap hard disk 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
replacing existing drives with ones containing a larger capacity.
Copyright IBM Corp. 2004
Before you begin, complete the following tasks:
Read the safety and handling guidelines in “Safety” on page iii and in “Handling
static-sensitive devices” on page 14.
Ensure that your current system configuration is working properly.
Back up all important data before you make changes to data storage devices.

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:
Blank trays: A storage server without a full set of drives (14) contains blank
trays in the unused drive bays. Before installing new drives, you must remove
these empty trays. Save the empty trays for future use. Each of the 14 bays
must always contain either a blank tray or a hot-swap hard disk drive.
Note:
For proper cooling and EMC protection, do not leave a drive slot open
without either a drive blank or a drive CRU inserted.
Drive CRUs: The FAStT100 supports up to fourteen IBM 1.5 Gbps SATA hard
disk drives.
Note: Do not use fibre-channel hard disk drive CRUs in the FAStT100.
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 CRU labels: A label is provided on the front of each hard disk drive. Use
this label to record the location information for each drive before you remove it.
Ensure that you keep track of the drives and their corresponding bays. Also,
record the location information in Table 17 on page 103. If you install a drive in
the wrong bay, you might lose data.
Drive LEDs: Each drive tray has two associated LEDs, a green Activity LED and
amber Fault LED, on the chassis of the FAStT100. These LEDs indicate the
status for that drive. See Table 14 for the drive LED states and descriptions.

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.
Installing hot-swap hard disk drives
You can install hard disk drives while the storage server is turned on and running.
