xxx IBM TotalStorage DS4100 Storage Server: Installation, User’s, and Maintenance Guide
Chapter 1. Introduction
This chapter describes the operating specifications, features, and components for
the IBM TotalStorage DS4100 storage server (hereafter referred to as DS4100 or
storage server). This chapter also includes a list of hardware that comes with the
storage server.
Overview
IBM DS4000 solutions support the large and growing data storage requirements of
business-critical applications. These scalable IBM DS4000 solutions offer you data
access and protection to meet your existing enterprise storage requirements and
prepare for the future.
Designed for data archival, data reference, and near-line storage applications, the
DS4100 utilizes the latest Serial Advanced Technology Attachment (SATA) disk
drive technology. The DS4100 supports up to fourteen 1.5 Gbps 250 GB SATA disk
drive modules, offering up to 3.5 terabytes (TB) of capacity per enclosure.
Note: SATA hard drive CRUs cannot be interchanged with the fibre-channel hard
drive CRUs that are supported in other DS4000 storage products.
The DS4100 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.
IBM currently offers two versions of the DS4100:
v DS4100 base storage server (Machine Type 1724, Model 100)
v DS4100 single-controller storage server (Machine Type 1724, Model 1Sx)
About the DS4100 base storage server
The DS4100 base (dual-controller) storage server (Machine Type 1724, Model 100)
is a rack-mountable storage server that comes with two RAID controllers, two power
supplies, and two cooling units. It provides dual, redundant controllers, redundant
cooling, redundant power, and battery backup of the RAID controller cache. The
DS4100 base storage server is designed to provide maximum host and drive-side
redundancy, enabling full redundant drive loop support to additional disk storage
capacity in the drive expansion enclosures via the drive loop port from each RAID
controller. In addition, each RAID controller supports direct attachment of two hosts
that contain two fibre channel host bus adapters each. External cables and small
form-factor pluggable (SFP) modules connect the storage server to the storage
expansion unit and the host servers.
Up to seven DS4000 EXP100 storage expansion units can be connected together
with the DS4100 base storage server in a fibre-channel loop, providing connections
to a maximum of 112 hard drives. With the DS4100 base storage server, you can

connections for expanding the DS4100 storage capacity to SATA hard drives in
external DS4000 EXP100 storage expansion units.
Currently, the only DS4000 storage expansion unit model that can be attached to
the DS4100 base storage server is the DS4000 EXP100. Do not connect other
DS4000 storage expansion units (such as the DS4000 EXP700 or DS4000
EXP710) to the DS4100 base storage server. Please contact your IBM support
representative for information about the availability of future support for connecting
other DS4000 storage expansion unit models.
Note: You must make fibre channel connections from the host server fibre channel
HBA ports to both controllers in the DS4100 base storage server to ensure
full host-side redundancy.
Attention
To ensure proper operation when connecting DS4000 EXP100 expansion units
to the DS4100 base storage server, you must verify that the DS4000 EXP100
ESM firmware level is at level 9554 or later. If the ESM firmware level is lower
than 9554, disconnect the DS4000 EXP100 and contact IBM support, your
IBM reseller, or your IBM representative for assistance.
About the DS4100 single-controller storage server
The DS4100 single-controller storage server (Machine Type 1724, Model 1Sx,
where x represents an upper-case alphanumeric character) is a rack-mountable
storage server that comes with one RAID controller, one power supply, and two
cooling units. It supports up to fourteen hot-swap internal disk drive slots, which
support over 3.5 TB of storage capacity when using 250 GB SATA disk drives.
External cables and small form-factor pluggable (SFP) modules connect the storage
server to the host server fibre channel HBA ports.
Notes:
1. The DS4100 single-controller storage server does not support storage capacity
expansion using external DS4000 EXP100 expansion units (or any other models
of DS4000 storage expansion units). In addition, it does not offer RAID
controller and drive loop redundancy.
2. The cache in the controller of the DS4100 single-controller storage server is
used for read operations only. No write operations will be cached.
The following limitations apply to this release of the DS4100 single-controller
storage server.
v All factory-delivered DS4100 RAID controllers are shipped with a recent version
of controller firmware loaded on the RAID controller, but that firmware version
might not match precisely the firmware version the RAID controller you need to
replace. When you replace the RAID controller in the DS4100 single-controller
storage server, if the firmware version of the replacement RAID controller is
determined to be incompatible with the configuration database during the boot
process, the DS4100 single-controller storage server will enter a Stop State and
will not allow any DS4000 Storage Manager operations to be performed. In this
case, you must manually upgrade or downgrade the replacement RAID controller
firmware to match the version required by the configuration database. See
“Manually upgrading the firmware for the DS4100 single-controller storage
server” on page 103.
2 IBM TotalStorage DS4100 Storage Server: Installation, User’s, and Maintenance Guide
v The DS4100 single-controller storage server does not support automatic firmware
updates. All firmware upgrades and downgrades for the DS4100 single-controller
storage server must be performed manually, as described in “Manually upgrading
the firmware for the DS4100 single-controller storage server” on page 103.
v All DS4100 single-controller storage server controller firmware updates must be
performed off-line.
v Yo u cannot upgrade from the DS4100 single-controller storage server to the
DS4100 base storage server. Please contact your IBM reseller or representative
for the possible availability of such support in the future.
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
is 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 DS4100 base storage server to the DS4000 EXP100 drive
expansion enclosure ports or fibre channel host bus adapter ports 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.
1
SATA defined
The Serial Advanced Technology Attachment (S ATA) 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).

Clustering support
Clustering is a means of sharing array groups among controllers to provide
redundancy of controllers and servers. This redundancy is important if a hardware
component fails. If a hardware component failure occurs in a cluster, another server
takes ownership of the array group.
Clustering requires software specific to your operating system. For more information
about clustering, go to the following Web site:
www.pc.ibm.com/us/compat/nos/matrix.shtml

Note:
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 DS4100 base storage server only: To maintain power redundancy, plug the
DS4100 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
6 IBM TotalStorage DS4100 Storage Server: Installation, User’s, and Maintenance Guide
the DS4000 storage expansion units attached to the DS4100 storage server
should be plugged into the same two independent external power circuits as the
DS4100. This ensures that the DS4100 storage server and all its attached
storage expansion units 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 56 on
page 62 for an example of redundant power connections.
This guideline cannot be followed for the DS4100 single-controller storage
Note:
server, which does not offer redundant power supplies. However, you can
use Uninterruptible Power Supply (UPS) units with the DS4100
single-controller storage server to provide protection against power
brown-outs and short power outages.
v Before any planned system shutdown or after any system additions, removals, or
modifications (including logical drive creations, storage partitioning definitions,
hardware changes, and so on), save the storage subsystem profile as explained
in the DS4000 Storage Manager guide for your operating system. Save the
profile in a location other than the logical drives created for the DS4100 storage
server.
v 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.
v During any maintenance or attended power-up procedure, carefully follow the
power-up sequence listed in “Turning on the storage server” on page 66. 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.
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 66 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
DS4000 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 DS4100 storage server.
Hot-swappable devices enable you to maintain the availability of your system while
you remove, install, or replace a hot-swap device. All DS4100 storage server
models support hot-swap SATA hard disk drives and cooling fan CRUs, so you can
remove and replace these components without turning off the storage server. In
addition, the DS4100 base storage server supports hot-swap RAID controllers and
power supplies.
Chapter 1. Introduction 7
Attention: The DS4100 single-controller storage server does not support
hot-swap RAID controllers or power supplies. You will lose access to data if you
attempt to remove or replace a functioning (non-failed) RAID controller or power
supply in a DS4100 single-controller storage server without first powering down the
storage server.
Hot-swap drive bays
The hot-swap drive bays that are accessible from the front of your storage server
are shown in Figure 2.
Hot-swap drive bays
f10ug052
Figure 2. DS4100 hot-swap drive bays
The DS4100 supports up to 14 DS4000 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 S ATA 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:
1. 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.
2. 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.
3. After you remove a drive CRU, wait at least 70 seconds before replacing or
reseating the drive CRU to allow the drive to properly spin down. Failure to do
so may cause undesired events.
If the hard disk drive you want to remove is not in a failed or bypass state,
Note:
always use the DS4000 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) in an offline state before you remove the drive from the enclosure.

Heat output, airflow, and cooling
The maximum heat output of the DS4100 is 390 watts (1235 BTU/hr). Each
DS4100 rack-mounted unit requires an airflow of 2.5 m
input air temperature to all rack cabinets should be in the range 10° C - 35° C (50°
F - 95° F). The recommended operating temperature is 22° C (72° F).
When rack cabinets that contain many DS4100s are to be installed together, the
following requirements must be met to ensure that the DS4100s are adequately
cooled:
v Air enters at the front of the rack cabinet and leaves at the back. To prevent the
air that is leaving the rack cabinet from entering the intake of another piece of
equipment, you must position the rack cabinets in alternate rows, back-to-back
and front-to-front. This arrangement is known as “cold aisle/hot aisle” and is
shown in Figure 8 on page 16.
v Where rack cabinets are in rows, each rack cabinet must touch the rack cabinet
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
cabinet. Yo u should use Suite Attach Kits to completely seal any gaps that
remain between the rack cabinets. For details about Suite Attach Kits, contact
your marketing representative.
v Where rack cabinets 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.
v To ensure correct airflow in each rack cabinet, the rack filler plates must be
installed in unused positions. Also, all the gaps in the front of the rack cabinets
must be sealed, including the gaps between the storage servers.

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 (ESD), 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 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. 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 DS4100 for installation into a rack
cabinet.
1. Prepare the site to meet all area, environmental, power, and site requirements.
For more information, see “Storage server operating environment” on page 13.
2. Move the DS4100 to the site.

are going to install the support rails.
Attention: Use the rack mounting template provided in Figure 9 on page 21
and Figure 10 on page 22 to locate the proper rack mounting holes for
installing the support rails into the rack cabinet.
Note the following considerations before you choose where to install the rails:
v If you are installing the DS4100 into an empty rack, install it into the lowest
available position so that the rack does not become unstable.
v If you are installing more than one DS4100 in the rack, start at the lowest
available position, and work upward.
v If appropriate, allow for possible later installation of other units.
v If necessary, remove the rack power distribution unit before you install the
support rails.
v For procedures and more information, refer to the installation and service
guide, or equivalent, for the rack cabinet.

Removing the CRUs
Attention: This section describes how to remove the CRUs in order to minimize
the weight of the DS4100 before you install it in the rack cabinet. However, if you
have three or more people available to lift and install the DS4100 in a rack cabinet,
you might not find it necessary to remove the CRUs before you install the DS4100.
If this is the case, you can skip the CRU removal instructions provided in this
section. Instead, continue with “Installing the DS4100 into a rack cabinet” on page
28, and then skip the CRU replacement instructions provided in “Replacing the
DS4100 CRUs” on page 29.
Use the following procedures to remove the CRUs from the DS4100 before
installation. Use these instructions after you have completed all applicable site, rack
cabinet, and DS4100 preparations (as discussed in “Preparing for installation” on
page 18) and installed the support rails (as discussed in “Installing the support rails”
on page 22). Alternately, if necessary, you can use these instructions to lighten the
DS4100 before removing it from the shipping box. The shipping box opens to
provide access to the storage server CRUs.
The DS4100 comes with a rack-mounting hardware kit for installing it in a rack
cabinet. It is easier to lift the DS4100 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 18. In the following procedure, you will remove the following
CRUs from the storage server before you install it in the rack cabinet:

f10ug046
Note: Some storage servers ship with a panel installed over the server ID switch to
prevent the server ID from being changed accidentally. If your storage server
has a protective panel over the server ID switch, use a pencil or a small
screwdriver to change the server ID.
Each storage expansion unit in a DS4000 storage subsystem drive loop must have
a unique enclosure ID. DS4000 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).
Note: The DS4100 is shipped with 00 as the default server ID setting. If you
connect the storage server to a DS4000 EXP100, you must set the DS4000
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

as the server ID.
Attention: When connecting the DS4100 to DS4000 EXP100 storage expansion
units, 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.
Storage server speed settings
The default switch setting is 2 Gbps. This is the only speed setting allowed for the
DS4100.
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 cabinet. 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 (in-band) management or direct (out-of-band)
management.
Important: If the operating system of the host server that the storage subsystem
logical drive(s) is mapped to is not Microsoft
to make a direct (out-of-band) 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 host-agent
(in-band) management.
Host-agent (in-band) management method
This method requires host-agent software that you install on the host server. The
host-agent software allows the DS4000 Storage Manager client program to manage
the DS4000 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 23 on page 35 shows the host-agent (in-band)
management method.

Direct (out-of-band) 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). Yo u will connect the cables to
each storage server controller later when you install the storage server. Figure 24
on page 36 shows the direct (out-of-band) management method.
Note: Do not connect the DS4100 storage server Ethernet ports to a public
network or public subnet. It is strongly recommended that you create a
private network between the DS4100 storage server and the management
station.

Fibre channel connections
The storage server fibre channel connection consists of up to four host
fibre-channel loops and a redundant drive fibre-channel loop. The host fibre-channel
loops provide the fibre path for host attachment. They can consist of fibre-channel
cables, SFPs, host bus adapters, fibre-channel switches, and RAID controllers. The
redundant drive fibre-channel loop provides the fibre path to the hard disk drives
(HDDs). The redundant drive fibre-channel loop consists of fibre channel HDDs and
optional storage expansion units, fibre-channel cables, and SFPs.
Exception: The DS4100 single-controller storage server does not support drive
loops or expansion units.
The DS4100 base 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 fiber-optic
cables to connect one expansion unit to another in a daisy-chain. For more
information about adding expansion units, see “Connecting expansion units (base
storage server only)” on page 57.
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
36 IBM TotalStorage DS4100 Storage Server: Installation, User’s, and Maintenance Guide
connect more than two hosts to the fibre channel storage server through switches.
The illustrations in the following sections show common host system configurations.
Note: The default configuration is one partition. Four-partition, eight-partition, and
sixteen-partition configuration upgrades are available as upgrade options.
You must perform partition upgrades one increment at a time, which means
you cannot upgrade directly from a four-partition configuration to a
sixteen-partition configuration; in this case, you would have to upgrade from
a four-partition configuration to an eight-partition configuration, and then from
the eight-partition configuration to a sixteen-partition configuration. Contact
your IBM reseller or marketing representative for more information.

44 IBM TotalStorage DS4100 Storage Server: Installation, User’s, and Maintenance Guide
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 65 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. 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:
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 you use 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 cabinet.
© Copyright IBM Corp. 2004 45
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 DS4100 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 DS4100 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 DS4100 to other fibre channel devices.
Before you install SFP modules and fiber-optic cables, read the following
information:
v Do 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 DS4000
Storage Manager client to view the storage subsystem profile in order to verify
that you are not mixing long-wave and short-wave SFPs.
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 Yo u 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 Yo u must insert the SFP module into a port before you connect the fiber-optic
cable.
v Yo u 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 48 for
more information.

required before attaching a DS4000 EXP100 to the DS4100 base storage server.
Refer to the section “Replacing a failed hot-swap ESM” in the IBM TotalStorage
DS4000 EXP100 Storage Expansion Unit Installation, User’s, and Maintenance
Guide for details on how to identify ESM firmware levels.
You cannot connect expansion units to the DS4100 single-controller storage server.
If you are using the DS4100 single-controller storage server, skip this section.
Please contact your IBM support representative for information about the availability
of such support in the future.
Chapter 3. Cabling the storage server 57
Attention: In the initial installation of the DS4100, you can add only new
expansion units to the DS4100 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 DS4100 storage server,
refer to the IBM TotalStorage DS4000 Hard Drive and Storage Expansion Enclosure
Installation and Migration Guide. Improper drive migration might cause loss of
configuration and other storage server problems. Contact your IBM support
representative for additional information.
To connect a single additional expansion unit to the storage server, perform the
following steps:
The following procedures are for ″cold-case″ procedures (the DS4100 is
Note:
powered down when expansion units are connected, as in the case of a new
installation). For ″hot-case″ procedures (the DS4100 is powered on when
expansion units are connected), see “Adding a DS4000 EXP100 to an
existing DS4100 configuration (base storage server only)” on page 109. Yo u
can also refer to the IBM TotalStorage DS4000 Hard Drive and Storage
Expansion Enclosure Installation and Migration Guide.
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 Figure 53 on page 59 to connect a single
expansion unit to the storage server:
a. Ensure that the enclosure ID switch on the new expansion unit is set to a
value different than the value set for the DS4100 and any other expansion
units in the loop. Also ensure that the link speeds of the expansion units are
set to 2 Gbps. See “Setting the interface options” on page 32.
When connecting the DS4100 to DS4000 EXP100 storage expansion
Note:
units, 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 33.
b. 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.
c. 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.

3. Remove the blank filler trays and insert drive trays. Connect power to the drive
expansion unit first and then connect power to the DS4100. After the storage
server is powered on, the storage server locates the new drives.
4. Use the DS4000 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 DS4100 Fibre Channel Cabling Instructions that come with the
storage server.
DS4000 EXP100 loop redundancy (DS4100 base storage server only)
The DS4000 EXP100 provides redundant loop support when the second ESM is
configured, and when both loops (called A and B) are connected to a DS4100
storage server model that supports redundant loops. (The DS4100 base storage
server supports redundant loops; the DS4100 single-controller storage server does
not support redundant loops.) If a cable or SFP module fails on drive loop A, drive
loop B provides redundancy, which is an alternate path to your disk drives.
Figure 54 on page 60 shows a redundant loop that you might create with a DS4100
and three DS4000 EXP100s. The numbers provided in Figure 54 on page 60 show
the order in which cables should be attached.

Figure 54. DS4000 EXP100 redundant loop configuration
To create the redundant loop shown in Figure 54, you would perform the following
steps:
1. Make two fibre-channel connections from the First expansion unit to the Second
expansion unit (connections 1 and 2).
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
DS4000 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 DS4000 EXP100 units.
3. 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).
4. 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 S ATA 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
DS4100 Fibre Channel Cabling Instructions for more information about dual-loop
support and implementation.
Each ESM on the DS4000 EXP100 has an SFP module input port and an SFP
module output port. As you cable DS4000 EXP100s together, connecting input ports
to output ports can improve diagnostic capability. Refer to the DS4100 Storage
Server Fibre Channel Cabling Instructions for cabling connections between input
and output ports.
60 IBM TotalStorage DS4100 Storage Server: Installation, User’s, and Maintenance Guide
Power cabling
The DS4100 base storage server uses two standard power cords, and the
single-controller storage server uses only one. You can connect the power cords to
a primary power unit inside the rack cabinet, such as a properly grounded ac
distribution unit, or to an external source, such as a properly grounded electrical
outlet.
The DS4100 storage server does not ship with power cords. Refer to Appendix C,
“Power cords,” on page 125 for the list of IBM-approved power cords for your
region. Depending on your model, the DS4100 storage server does ship with one or
two line jumper cords for connecting the DS4100 power supply or power supplies to
an IBM-approved rack power distribution unit.
If you have not already done so, attach the power cords by using Figure 55 for the
location of the component parts.

Perform the following to cable the power cords:
1. Connect the power cord to the power supply.
2. Remove the nut that holds the power cable strain-relief clamp, and then remove
the strain-relief clamp.
3. Wrap the strain-relief clamp around the power cord approximately 20 cm (8 in.)
from the power supply connection end. Leave some slack between the clamp
and the power-supply end of the power cord.
4. Replace the power cable strain-relief clamp, and tighten it securely with the nut.
5. Plug the power cord into a properly grounded electrical outlet.
Note: To maintain power redundancy, plug the storage server’s right and 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 DS4000
storage expansion units attached to the DS4100 should be plugged into
the same two independent external power circuits as the DS4100.
It is recommended that you determine the maximum surge current
possible when all devices in the power circuit are started at the same
time. Based on the total number of devices on a power circuit, find the
maximum (worst-case) specification value in order to prevent the circuit
from tripping. When both power supplies are connected and the storage
server is powered on, each power supply unit will handle approximately
Chapter 3. Cabling the storage server 61
one-half of the current load. If there is only one power supply unit, it will
handle all of the current load. To ensure maximum protection against
power loss due to power supply unit failure or a power circuit tripping,
both power supply units must be connected and powered on. See
Table 10 on page 15 for the DS4100 AC power requirements.
See Figure 56 for an example of redundant power cabling.
Exception: The DS4100 single-controller storage server has only one
power supply, so it does not support power redundancy.

Installing the DS4000 Storage Manager client
Refer to the IBM TotalStorage DS4000 Storage Manager 9.10 Installation and
Support Guide for the appropriate operating system for instructions on how to install
the Storage Manager software. Use that document and the online help to configure
the logical drives, partitions, and so on for the RAID controllers. Use your operating
62 IBM TotalStorage DS4100 Storage Server: Installation, User’s, and Maintenance Guide
system documentation to make the new logical drives accessible to the operating
system. Do not proceed with the configuration set-up you have completed the
DS4000 Storage Manager installation.
Assemble any additional items in preparation for software installation. These items
might include:
v HBA drivers
v Controller firmware version 05.42.xx.xx
v IP addresses for RAID controllers (for in-band management only)
v Additional documentation for switches and HBAs, if needed
v DS4000 Storage Manager Version 9.10 Support CD, which includes the IBM
DS4000 Storage Manager 9.1 software and DS4000 storage server controller

modifications (including logical drive creations, storage partitioning definitions,
hardware changes, and so on), save the storage subsystem profile as explained in
the DS4000 Storage Manager guide for your operating system. Save the profile in a
location other than the logical drives created for the DS4100 storage server.
Important: Controller firmware version 05.42.xx.xx is required for the DS4100.
However, this version of the controller firmware should be used only for
the DS4100. Do not use controller firmware version 05.42.xx.xx for any
DS4000 storage servers other than the DS4100. This version of the
controller firmware does not support intermix of fibre-channel drive
expansion enclosures. Please contact your IBM support representative
for information about the availability of such support in the future.
Always refer to the readme that is included with the DS4100 storage
server firmware package (whether the firmware is accessed by the Web
or CD) for any special requirements or restrictions that apply to that
particular firmware version.
Note: Make sure that you install the DS4000 Storage Manager event monitoring
service to enable continuous monitoring of the status of the storage server.
For more information about the importance of this information, see
“Monitoring status through software” on page 70.

64 IBM TotalStorage DS4100 Storage Server: Installation, User’s, and Maintenance Guide
Chapter 4. Operating the storage server
To ensure optimal operation of your system, always follow these best practices
guidelines:
v Back up the data on your storage drives periodically.
v DS4100 base storage server only: To 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 DS4000
storage expansion units attached to the DS4100 should be plugged into the
same two independent external power circuits as the DS4100. This ensures that
the DS4100 and all its attached storage expansion units 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 56 on page 62 for an example of redundant power
connections.
v Before any planned system shutdown or after any system additions, removals, or
modifications (including logical drive creations, storage partitioning definitions,
hardware changes, and so on), save the storage subsystem profile as explained
in the DS4000 Storage Manager guide for your operating system. Save the
profile in a location other than the logical drives created for the DS4100 storage
server.
v 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.
v During any maintenance or attended power-up procedure, carefully follow the
power-up sequence listed in “Turning on the storage server” on page 66. 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.
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 66 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
DS4000 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 69.

Turning on the storage server
Important: DS4100 base storage server only: You must turn on the storage
expansion units and verify that the storage expansion unit fibre channel
connections are optimal by checking the indicator lights before you turn
on the DS4100. The controllers might not recognize the correct
configuration if the hard disk drives are powered up after the DS4100.
For instructions on how to power up the storage expansion units, refer
to the storage expansion unit documentation.
Always wait at least 30 seconds between the time you turn off a power
Note:
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:
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 hard disk drives” on page 80.
Note: At least one drive must be present before you start the DS4100.
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 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.
b. Yo u 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.
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
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.
3.
To turn on power to the storage server, turn on the power-supply switches on
the back of the storage server. Yo u must turn on both power-supply switches to
take advantage of the redundant power supplies.
4. Use the DS4000 Storage Manager client and the Fault LEDs to check the
overall status of the storage server and its components. All LEDs should be
66 IBM TotalStorage DS4100 Storage Server: Installation, User’s, and Maintenance Guide
green on the front of the storage server. If they are not, use the DS4000
Storage Manager client to diagnose the problem (see “Monitoring status through
software” on page 70).
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 71.
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 DS4000
Storage Manager client 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 DS4000 Storage Manager client to diagnose
the problem (see “Monitoring status through software” on page 70). This ensures
that the storage server will power up correctly later. For more information, see
Chapter 6, “Hardware maintenance,” on page 111 .
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 69).
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.

Perform the following steps to turn off the power:
1. Before proceeding, use the DS4000 Storage Manager client 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 DS4000 Storage Manager client to check the status of the storage
server. Correct problems that are reported before you turn off the power.
Chapter 4. Operating the storage server 67
3. 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.
v The green Cache active LEDs on the back of the storage server are 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 6 for the proper shutdown sequence.
4. Before the storage server is powered off, use the operating system software to
either disconnect the storage server logical drives from the host or to flush the
logical drive data cache in the host server memory.
5. If applicable, use the operating system software to disconnect the storage
server logical drives from the host before the storage server is powered off.
6. 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.
7. After you perform the necessary maintenance procedures, turn on the power
using the procedure in “Turning on the storage server” on page 66.
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 DS4000 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 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 Yo u are forced to shut down the storage server without performing the normal
shutdown procedures (listed in “Turning off the storage server” on page 67)
because of an emergency situation.
