The server diagnostic programs are stored in upgradable read-only memory (ROM)
on the system board. These programs are the primary method of testing the major
components of the server: The system board, Ethernet controller, video controller,
RAM, keyboard, mouse (pointing device), diskette drive, serial ports, hard drives,
and parallel port. You can also use them to test some external devices. See
Also, if you cannot determine whether a problem is caused by the hardware or by the
software, you can run the diagnostic programs to confirm that the hardware is
working properly.
When you run the diagnostic programs, a single problem might cause several error
messages. When this occurs, work to correct the cause of the first error message.
After the cause of the first error message is corrected, the other error messages might
not occur the next time you run the test.
A failed system might be part of a shared DASD cluster (two or more systems sharing
the same external storage device(s)). Prior to running diagnostics, verify that the
failing system is not part of a shared DASD cluster.
A system might be part of a cluster if:
•
•
The customer identifies the system as part of a cluster.
One or more external storage units are attached to the system and at least one of
the attached storage units is additionally attached to another system or
unidentifiable source.
•
One or more systems are located near the failing system.
If the failing system is suspected to be part of a shared DASD cluster, all diagnostic
tests can be run except diagnostic tests which test the storage unit (DASD residing in
the storage unit) or the storage adapter attached to the storage unit.
Notes:
1. For systems that are part of a shared DASD cluster, run one test at a time in
looped mode. Do not run all tests in looped mode, as this could enable the DASD
diagnostic tests.
2. If multiple error codes are displayed, diagnose the first error code displayed.

Server features
The unique design of the server takes advantage of advancements in symmetric
multiprocessing (SMP), data storage, and memory protection. The server combines:
•
Impressive performance using an innovative approach to SMP
The server supports up to four Pentium III Xeon microprocessors. The server
comes with one microprocessor installed; you can install additional
microprocessors to enhance performance and provide SMP capability.
•
Integrated disk-array subsystem (optional)
Although many operating systems provide software fault tolerance through
mirroring, IBM provides hardware fault tolerance through the redundant array of
independent disks (RAID) controller. The IBM ServeRAID™ controller is a
standard feature. It provides three channels and supports RAID levels 0, 1, 1E, 5,
and 5E.
•
•
Large data-storage and hot-swap capabilities
All models of the server support up to 10 slim-high disk drives. The hot-swap
feature enables you to remove and replace hard disk drives without turning off
the server.
Hot-plug PCI adapter capabilities
The server has four hot-plug slots for PCI adapters. With operating system
support, you can replace failing hot-plug PCI adapters without turning off the
server. If the hot-add feature is supported by the operating system and the PCI
adapter, you can also add PCI adapters in these slots without turning off the
server.
•
Redundant cooling and power capabilities
The redundant cooling and hot-swap capabilities of the fans in the server enable
continued operation if one of the fans fails, because you can replace a failing fan
without turning off the server.
The server comes standard with three 250-watt power supplies, which support
redundancy for a typical configuration. You can install one additional power
supply.
•
•
Large system memory
The memory bus in the server supports up to 16 GB of system memory. The
memory controller provides error correcting code (ECC) support for up to 16
industry-standard, 3.3 V, 168-pin, 8-byte, registered, dual inline memory modules
(DIMMs). The memory controller also provides Chipkill™ memory protection.
Chipkill memory protection is a technology that protects the system from
component failure on a DIMM.
System-management capabilities
The server comes with a Advanced System Management Processor. This
processor enables you to manage the functions of the server locally and remotely.
The Advanced System Management Processor also provides system monitoring,
event recording, and dial-out alert capability.

information.
•
•
•
Integrated network environment support
The server comes with an Ethernet controller. This Ethernet controller has an
interface for connecting to 10-Mbps or 100-Mbps networks. The server
automatically selects between 10BASE-T and 100BASE-TX. The controller
provides full-duplex (FDX) capability, which enables simultaneous transmission
and reception of data on the Ethernet local area network (LAN).
Redundant network-interface card
The addition of an optional, redundant network interface card (NIC) provides a
failover capability to a redundant Ethernet connection. If a problem occurs with
the primary Ethernet connection, all Ethernet traffic associated with this primary
connection is automatically switched to the redundant NIC. This switching
occurs without data loss and without user intervention.
IBM ServerGuide CDs
The ServerGuide CDs included with the server provide programs to help you set
up the server and install the network operating system (NOS). The ServerGuide
program detects the hardware options that are installed, and provides the correct
configuration program and device drivers. In addition, the ServerGuide CDs
include a variety of application programs for the server.
Reliability, availability, and serviceability
Three of the most important features in server design are reliability, availability, and
serviceability (RAS). These factors help to ensure the integrity of the data stored on
the server; that the server is available when you want to use it; and that should a
failure occur, you can easily diagnose and repair the failure with minimal
inconvenience.
The following is an abbreviated list of the RAS features that the server supports.

server components. These LEDs are part of the light-path diagnostics that are
built into the server. By following the path of lights, you can quickly identify the
more information.

These charts list problem symptoms, along with suggested steps to correct the
POST
When you turn on the server, it performs a series of tests to check the operation of
server components and some of the options installed in the server. This series of tests
is called the power-on self-test or POST.
If POST finishes without detecting any problems, a single beep sounds, the first screen
of the operating system or application program appears, and the System POST
Complete (OK) light is illuminated on the operator information panel.
If POST detects a problem, more than one beep sounds and an error message appears
information.
Notes:
1. If you have a power-on password or administrator password set, you must type
the password and press Enter, when prompted, before POST will continue.
2. A single problem might cause several error messages. When this occurs, work to
correct the cause of the first error message. After you correct the cause of the first
error message, the other error messages usually will not occur the next time you
run the test.
POST beep codes
POST generates beep codes to indicate successful completion or the detection of a
problem.
•
•
One beep indicates the successful completion of POST.
More than one beep indicates that POST detected a problem. For more
information, see “Beep symptoms” on page 143.
POST error messages
POST error messages occur during startup when POST finds a problem with the
hardware or detects a change in the hardware configuration. For a list of POST
errors, see “POST error codes” on page 155.
Event/error logs
The POST error log contains the three most recent error codes and messages that the
system generated during POST. The System Event/ Error Log contains all error
messages issued during POST and all system status messages from the Advanced
System Management Processor.
To view the contents of the error logs, start the Configuration/ Setup Utility program;
then, select Event/Error Logs from the main menu.
Small computer system interface messages
Note: If the server does not have a hard disk drive, ignore any message that indicates
that the BIOS is not installed.

You will get these messages only when running the SCSISelect Utility.
Solving ServeRAID problems
This section describes the ServeRAID text and numeric messages that might appear
during startup. This section also includes some basic information about rebuilding a
defunct drive.
In addition to the information provided in this section, you might want to use the
ServeRAID IPSSEND program to help isolate ServeRAID problems.
ServeRAID controller messages
This section lists the ServeRAID messages that might appear during system startup.
The ServeRAID controllers provide a Device Event Log that collects statistics on the
number and types of events that occur on a selected physical drive. After correcting a
problem with the array, clear the log so that you can identify any subsequent errors
All physical drives contain unique identifiers, such as the drive serial number and
manufacturer. During configuration, the ServeRAID controller stores this
information.
ServeRAID startup messages
During power-on self-test (POST), the ServeRAID controller compares the stored
configuration information to the configuration that is actually present. If a
discrepancy exists, one or more status messages appear after POST completes, but
before the operating system loads.
Notes:
1. When the ServeRAID controller requires your input, a list of function keys will
appear below the message.
2. Where the Action information tells you to start the IBM ServeRAID configuration
program, insert the IBM ServeRAID Support CD into the CD-ROM drive; then,
restart the server. The Action column also provides general information about
the message.
3. Where SID or ch appears in these messages, sid is the SCSI ID for the device, and
ch is the channel to which the device is attached.
4. Where m or n appears in these messages, a number will appear in the actual
message.
Following are messages associated with the ServeRAID subsystem in alphabetical
order.
A new drive was installed.
Explanation: When the ServeRAID controller detects a new drive that is not part of the
current configuration, the following message appears:
x new ready drives found
where x is the number of ready drives found.
Action: This is an information message. No action is required.

Explanation: Auto rearrange is enabled or disabled.
Action: This is an information message. No action is required.
Battery-Backup Write Cache Not Responding
Explanation: BIOS code detected a bad or failed battery-backup write cache.
Action: Press F9 to remove the battery-backup write cache from the configuration, or press
F10 to exit without change.
Battery-Backup Write Cache Replacement
Explanation: The ServeRAID controller detects that the battery-backup write cache is
defective.
Action: Press F8 if you replaced the battery-backup write cache, or press F10 if you have not
replaced the battery-backup write cache.
Configured drives are missing.
Explanation: When the ServeRAID controller detects that a previously configured drive is
missing, the following message appears:
x online drives not responding
where x is the number of drives not responding. Example of a possible message: Online
Drive on Channel 3 SCSI ID 3 is not responding.
Action: Press one of the following keys:
F2 – Detailed description. Press this key for a detailed description of the problem, such as the
example message above.
F4 – Retry. Press this key after correcting a problem. For example, press F4 after you turn on
the external storage enclosure that contains the physical drive.
F5 – Change the configuration and set the drives to defunct. Press this key to accept the new
state that the ServeRAID controller will assign to the drive. For example, the ServeRAID
controller will assign the drive a state of defunct or empty. You can also press F5 when you
must remove a drive. RAID level-1 and RAID level-5 logical drives are present, and
performance in a degraded mode is acceptable. The ServeRAID controller will assign the
drive a state of defunct, but the server can complete startup. However, the array will remain
in critical mode and the potential for data loss will exist until you replace and rebuild the
defunct drive. To prevent the loss of data, replace and rebuild the defunct drive in a timely
manner.
Note: A physical drive in the defunct state does not necessarily mean that you need to
replace the drive. Before you replace the drive, ensure that:
1. All cables are connected properly to the backplane and to the physical drive.
Also, ensure that all cables inside the server are connected properly.
2. The hot-swap drive trays are seated properly in the drive bay.
After you perform these steps, if the physical drive does not function properly, replace the
drive.
F10 – Continue booting without changing the configuration. Press this key to continue
without change to the configuration.

Configured drives are not in the configured location.
Explanation: When the ServeRAID controller detects that a previously configured drive is
present, but the drive is in a new location, the following message appears:
x online drive has been rearranged
where x is the number of drives that have been rearranged. Examples of possible messages
are:
Online Drive on Channel 3 SCSI ID 4 moved to Channel 3 SCSI ID 3
Online Drive on Channel 3 SCSI ID 3 moved to Channel 3 SCSI ID 4
Action: Press one of the following keys:
F2 – Detailed description. Press this key for a detailed description of the problem, such as the
example messages above.
F4 – Retry. Press this key after correcting a problem. For example, press F4 after you move
the physical drive to its previously assigned location.
F5 – Change the configuration and set the drive to defunct. Press this key to accept the new
state that the ServeRAID controller will assign to the drive. For example, the ServeRAID
controller will assign the drive a state of defunct or empty.
Note: A physical drive in the defunct state does not necessarily mean that you need to
replace the drive. Before you replace the drive, ensure that:
1. All cables are connected properly to the backplane and to the physical drive.
Also, ensure that all cables inside the server are connected properly.
2. The hot-swap drive trays are seated properly in the drive bay.
3. If you have not already attempted to rebuild the drive, try rebuilding it. See
“Rebuilding a defunct drive” on page 23 for more information.
After you perform these steps, if the physical drive does not function properly, replace the
drive.
F6 – Change the configuration and accept the rearrangement. Press this key to modify the
configuration to match the current drive location. You might remove the hot-swap drives
from the server for security or maintenance reasons. If you replace the drives but install them
in different drive bays, you can press F6 to accept the new locations, and the ServeRAID
controller will update the configuration.
F10 – Continue startup without changing the configuration. Press this key to continue
without change to the configuration.

New controller installed in a configured server or drives are imported.
Explanation: When the ServeRAID controller detects that the identifiers of the drives do not
match the controller configuration information, the following message appears: x online
drive(s) found with mismatch configuration Examples of possible messages:
Configuration mismatch Channel 1 SCSI ID 0 with Host ID
Configuration mismatch Channel 2 SCSI ID 0 with Host ID
Action: Press one of the following keys:
F2 – Detailed description. Press this key for a detailed description of the problem, such as the
example messages above.
F4 – Retry. Press this key after correcting the problem. For example, press F4 after you move
the physical drive to its previously assigned location, or after you install the original physical
drives back in the server.
F5 – Change the configuration and set the drive to defunct. Press this key to accept the new
state that the ServeRAID controller will assign to the drive. For example, the ServeRAID
controller will assign the drive a state of defunct or empty.
Note: A physical drive in the defunct state does not necessarily mean that you need to
replace the drive. Before you replace the drive, ensure that:
1. All cables are connected properly to the backplane or processor or I/ O board, and to the
physical drive. Also, ensure that all cables inside the server are connected properly.
2. The hot-swap drive trays are seated properly in the drive bay.
After you perform these steps, if the physical drive does not function properly, replace the
drive.
F7 – Import configuration information from drive. Press this key to restart the server. Press
this key to import the configuration information from the drive and to update the
configuration information for the ServeRAID controller. This choice is useful when you
replace the ServeRAID controller in an existing ServeRAID subsystem. You also might press
F7 if you replace a whole set of drives with drives that were configured in another server with
a ServeRAID controller. When you install drives in a server that has no logical drives
defined, the F7 choice will not appear. The ServeRAID controller does not contain any logical
drives in its factory configuration. Therefore, F7 will not appear. In this case, do the
following:

Rebuilding a defunct drive
A physical drive is defunct when there is a loss of communication between the
controller and the physical drive. This can be caused by any of the following:
•
•
•
An improperly connected cable, physical drive, or controller
A loss of power to a drive
A defective cable, backplane, physical drive or controller
Diagnostics 23
Download from Www.Somanuals.com. All Manuals Search And Download.
In each case, the communication problem needs to be resolved, and then a rebuild
operation is required to reconstruct the data for the device in its disk array. The
ServeRAID controllers can reconstruct RAID level-1 and RAID level-5 logical drives,
but they cannot reconstruct data stored in RAID level-0 logical drives.
To prevent data-integrity problems, the ServeRAID controllers sets the RAID level-0
logical drives to blocked during a rebuild operation. After the rebuild operation
completes, you can unblock the RAID level-0 logical drives, and access them once
again. Remember, however, that the logical drive might contain damaged data.
Steps for recovering from defunct drives
If the defunct drives are part of an array, do the following:
•
If more than one physical drive in an array is defunct, replace DDD drives and
restore from backup.
•
•
If a rebuild operation is in progress, wait until the rebuild is complete.
If a rebuild is not in progress and only one physical drive in the array is defunct,
replace the drive.
Rebuilding a hot-swap drive
A hot-swap rebuild refers to a rebuild operation that is started by the ServeRAID
controller when it detects that a drive that is part of a RAID-I or RAID-J array and in
the defunct state has been removed and reinserted on the SCSI backplane. The
reinsertion of the physical drive, whether it is the same drive or a new drive, will
trigger the ServeRAID controller to start the rebuild operation. During the rebuild
operation, the drive being rebuilt is in the rebuild state, and the logical drive remains
critical until the rebuild operation has been successfully completed.
On IBM servers, when a hot-spare drive is available, the rebuild operation will begin
automatically without the requirement to replace the failed drive.
To start a hot-swap rebuild, do the following:
1. Without removing the drive completely, gently remove the physical drive from
the server, using the handle of the hot-swap tray. If necessary, refer to the
documentation that comes with your server on removing a physical drive.
2. Wait 20 seconds to allow the physical drive to completely spin down.
Note: When power is removed from a hot-swap drive, the drive immediately
parks the heads, locks the actuator in the "landing zone", and begins
spinning down. However, the spinning down of the disk might require up
to 20 seconds after power is removed. Do not move the drive while it is
spinning down. Moving the drive while it is spinning down may damage
the drive.
3. Gently replace into the server the physical drive that you removed. Make sure the
drive is completely installed in the backplane connector.
Recovering from an incomplete format of a physical
drive
During formatting of a physical drive, if the format process is stopped by a system
reset, system shut down, power outage, or by some other means, the physical drive
becomes inoperable.
To enable the physical drive to communicate with the ServeRAID controller again, do
the following:
24 Hardware Maintenance Manual: xSeries 250
Download from Www.Somanuals.com. All Manuals Search And Download.
1. Note the channel of the ServeRAID controller to which the physical drive is
connected.
2. Note the SCSI ID of the physical drive.
3. Use ipssend format to restart the format of the physical drive. The syntax is:
ipssend format controller channel sid
where:
•
•
•
controller is the ServeRAID controller number (1–12)
channel is the channel number for the device (1, 2, or 3)
sid is the SCSI ID for the device (0–15)
After the format is complete, the ServeRAID controller will be able to recognize
the drive again.
Recovering from a failure in a failover-environment
In a failover environment, when the ServeRAID device driver is unable to send a
command to the primary controller and the primary controller does not respond to a
reset command, the device driver attempts to failover to the secondary controller.
Note: Loose cables or defective physical drives will not cause a failover to occur.
Replacing a non-hot-plug controller in a failover pair
If a failed controller is not in a hot-plug PCI slot, do the following to replace it:
1. Shutdown the server.
2. Replace the failed controller.
3. Reconfigure the new controller.
Notes:
1. Be sure the firmware level of the new controller is the same as the controller you
are replacing. Be sure to use the same controller name, partner name, and SCSI
initiator ID for the controller you are replacing.
2. For detailed instructions, refer to the Hardware Maintenance Manual for the
ServeRAID controller being serviced.
If the failed controller is in a hot-plug slot, refer to the documentation that comes with
the server for instructions for replacing the controller.
Diagnostic programs and error messages
The server diagnostic programs are stored in upgradable read-only memory (ROM)
on the system board. These programs are the primary method of testing the major
components of the server.
Diagnostic error messages indicate that a problem exists; they are not intended to be
used to identify a failing part. Troubleshooting and servicing of complex problems
that are indicated by error messages should be performed by trained service
personnel.
Sometimes the first error to occur causes additional errors. In this case, the server
displays more than one error message. Always follow the suggested action
instructions for the first error message that appears.
The following sections contain the error codes that might appear in the detailed test
log and summary log when running the diagnostic programs.

Power checkout
Power problems can be difficult to troubleshoot. For instance, a short circuit can exist
anywhere on any of the power distribution busses. Usually a short circuit will cause
the power subsystem to shut down because of an overcurrent condition.
A general procedure for troubleshooting power problems is as follows:
1. Power off the system and disconnect the AC cord(s).
2. Check for loose cables in the power subsystem. Also check for short circuits, for
instance if there is a loose screw causing a short circuit on a circuit board.
3. Remove adapters and disconnect the cables and power connectors to all internal
and external devices until system is at minimum configuration required for
4. Reconnect the AC cord and power on the system. If the system powers up
successfully, replace adapters and devices one at a time until the problem is
isolated. If system does not power up from minimal configuration, replace FRUs
of minimal configuration one at a time until the problem is isolated.
To use this method it is important to know the minimum configuration required for a

the 10/ 100 Mbps Ethernet controller.
Diagnostics 35
Download from Www.Somanuals.com. All Manuals Search And Download.
Network connection problems
If the Ethernet controller cannot connect to the network, check the following:
•
Make sure that the cable is installed correctly.
The network cable must be securely attached at all connections. If the cable is
attached but the problem persists, try a different cable.
If you set the Ethernet controller to operate at 100 Mbps, you must use Category 5
cabling.
If you directly connect two workstations (without a hub), or if you are not using a
hub with X ports, use a crossover cable.
Note: To determine whether a hub has an X port, check the port label. If the label
contains an X, the hub has an X port.
•
•
Determine if the hub supports auto-negotiation. If not, try configuring the
integrated Ethernet controller manually to match the speed and duplex mode of
the hub.
Check the Ethernet controller lights on the operator information panel.
These lights indicate whether a problem exists with the connector, cable, or hub.
— The Ethernet Link Status light illuminates when the Ethernet controller
receives a LINK pulse from the hub. If the light is off, there might be a
defective connector or cable, or a problem with the hub.
— The Ethernet Transmit/ Receive Activity light illuminates when the Ethernet
controller sends or receives data over the Ethernet Network. If the Ethernet
Transmit/ Receive Activity light is off, make sure that the hub and network
are operating and that the correct device drivers are loaded.
— The Ethernet Speed 100 Mbps light illuminates when the Ethernet controller
LAN speed is 100 Mbps.
•
•
•
Make sure that you are using the correct device drivers, supplied with the server.
Check for operating system-specific causes for the problem.
Make sure that the device drivers on the client and server are using the same
protocol.
•
Test the Ethernet controller.
How you test the Ethernet controller depends on which operating system you are
using (see the Ethernet controller device driver README file).

when loading device drivers.
Check the following:
•
Determine if the interrupt (IRQ) setting assigned to the Ethernet controller is also
assigned to another device in the Configuration/ Setup Utility program.
Although interrupt sharing is allowed for PCI devices, some devices do not
function well when they share an interrupt with a dissimilar PCI device. Try
changing the IRQ assigned to the Ethernet controller or the other device. For
example, for NetWare Versions 3 and 4 it is recommended that disk controllers not
share interrupts with LAN controllers.
•

•
Make sure that the hub is turned on.
Check all connections at the Ethernet controller and the hub.
Check the cable. A crossover cable is required unless the hub has an X designation.
Use another port on the hub.
If the hub does not support auto-negotiation, manually configure the Ethernet
controller to match the hub.
•
•
If you manually configured the duplex mode, make sure that you also manually
configure the speed.
Run diagnostics on the LEDs.
The Ethernet Transmit/
Receive Activity light does

without turning off the server. In the past you would need to turn off the server and
disconnect power to perform these operations. With the hot-plug features, you can
remove the top cover of the server with the power on.
The server supports hot plug, hot add, and hot swap devices and is designed to
operate safely while turned on with the top cover removed. The server is designed to
protect you and the server. Follow these guidelines when you work inside a server
that is turned on:
•
Avoid loose-fitting clothing on your forearms. Button long-sleeved shirts before
working inside the server; do not wear cuff links while you are working inside the
server.
•
•
Do not allow your necktie to hang inside the server.
Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist
watches.
•
•
Remove items from your shirt pocket (such as pens or pencils) that could fall into
the server as you lean over it.
Take care to avoid dropping any metallic objects, such as paper clips, hair pins, or
screws, into the server.

Working with adapters
You can install up to six PCI adapters in the expansion connectors on the processor
board. All six of the slots are peripheral component interconnect (PCI) expansion
slots.
The server comes with an integrated super video graphics array (SVGA) video
controller, which is not removable. If you want to disable this controller and use a
video adapter instead, you can install a video adapter in an expansion slot. When you
install a PCI video adapter, the server BIOS automatically disables the integrated
video controller.
Note: Video adapters are supported in all six PCI slots.
The following illustration shows the location of the 64-bit PCI expansion slots on the
processor board.

Review the documentation that comes with the adapter and follow those
instructions in addition to the instructions given in this chapter. If you need to
change the switch or jumper settings on the adapter, follow the instructions that
come with the adapter documentation.
Slots 3 through 6 support 5.0V, 3.3V, and universal PCI adapters.
Note: Universal PCI adapters support both 3.3V and 5.0V operation.
Slots 1 and 2 support 3.3 V and universal non-hot-swap PCI adapters only.
•
•
The server uses a rotational interrupt technique to configure PCI adapters.
Because of this technique, you can install a variety of PCI adapters that currently
do not support sharing of PCI interrupts.
•
•
The system scans PCI slots 1 through 6 to assign system resources; then the
system starts (boots) the PCI devices in the following order: processor board
devices, slots 1 and 2, and then slots 3 through 6.
The performance of the PCI adapters depends on the types of adapters in the
system.

LVD SCSI backplane
The server contains hardware that enables you to replace a failed hard disk drive
without turning off the server. Therefore, you have the advantage of continuing to
operate your system while a hard disk drive is removed or installed. These drives are
known as hot-swap drives. The hot-swap drives are attached to a hot-swap hard disk
drive backplane. The backplane is a printed circuit board behind the drive bays. For
more information on drive bays and drive installation, see “Installing internal drives”
As shipped, the LVD SCSI hot-swap hard disk drive backplane supports a split, dual-
channel configuration. You can install a maximum of 10 slim-high, hot-swap hard
disk drives. You can attach five drives to each half of the backplane. These drives must
be low voltage differential (LVD) hard disk drives that operate at 160 MB per second
or lower.
You can configure the channels on the SCSI backplane in one of two ways:
•
You can configure each SCSI channel (bus) independently. This is the standard
backplane configuration. In this configuration:
— The hard disk drives in the upper half of the backplane are attached to
channel A through a SCSI cable that comes attached to the SCSI backplane.
— The hard disk drives in the lower half of the backplane are attached to
channel B through a second optional SCSI cable. One end of this second SCSI
cable comes attached to the SCSI channel B connector on the backplane. The
other end of this cable is folded and restrained with a clamp.
When you are installing hot-swap hard disk drives in the standard backplane
configuration, attach the first five to channel A; then, attach the remainder to
channel B. Refer to the illustration in this section for the SCSI channel connector
locations.
•
You can choose to configure the SCSI backplane as a single 10-drive SCSI channel.
Notes:
1. The LVD SCSI backplane is also known as the SCSI backplane or the hot-swap
hard disk drive backplane.
2. Table 14 on page 98 lists the SCSI identifiers (IDs) for the LVD SCSI backplane and
the hot-swap hard disk drives that are attached to SCSI channels A and B.
3. Carefully route all cables so that they do not become damaged.
4. Cable identifiers are printed on the cables that come with your server and
options. Use these identifiers to attach the cables to the correct connectors. For
example, the hard disk drive cables are labeled "HDD".
5. For information on cabling options and using the LVD SCSI backplane, refer to
the documentation that comes with the option kit.

Your server contains hardware that enables you to replace a failed hard disk drive
without turning off the server. Therefore, you have the advantage of continuing to
operate the system while a hard disk drive is removed or installed. These drives are
known as hot-swap drives.
Each hot-swap drive has two indicator lights on the front of the server. If the amber
hard-disk status light for a drive is lit continuously, that individual drive is faulty and
needs to be replaced. When the hard-disk status light indicates a drive fault, you can
replace a hot-swap drive without turning off the server.
Each hot-swap drive that you plan to install must be mounted in a hot-swap-drive
tray. The drive must have a single connector attachment (SCA) connector. Hot-swap-
drive trays come with hot-swap drives.
Internal drive bays
Internal drives are installed in bays.
•
Your server comes with one CD-ROM drive and one 3.5-inch, 1.44 MB diskette
drive.

The left front bays support 5.25-inch, half-high, removable-media drives. Any
two adjacent 5.25-inch, half-high bays can be converted to a single full-high bay.
Note: The server EMI integrity and cooling are both protected by having the left
front bays covered or occupied. When you install a drive, save the filler
panel from the bay, in case you later remove the drive and do not replace it
with another.
•
You cannot install hard disk drives in the left front bays. You can install hot-swap
hard disk drives only in the hot-swap hard disk drive bays on the right front side
of the server.
•
•
If you are installing a device with a 50-pin connector in one of the left front bays,
you will need a 68-to-50-pin converter (option number 32G3925).
Your server supports ten 1-inch (26 mm) slim-high, 3.5-inch hot-swap hard disk
drives in the hot-swap bays.

Some drives have a special interface called small computer system interface, or SCSI.
Using this interface, you can attach multiple drives to a single SCSI controller.
Notes:
1. Any information about SCSI drives also applies to other SCSI devices, such as
scanners and printers.
2. If you plan to install both internal and external SCSI devices, you must follow the
instructions in this section.
A 16-bit (wide) low voltage differential (LVD) SCSI cable connects the hard disk drive
backplane to the ServeRaid adapter located in a PCI slot on the processor board. An
additional 16-bit, two-drop SCSI cable comes with the server. It is located in the
bottom of the server media bay and is restrained with a cable clamp.
If you want to install SCSI devices in the removable media bays:
1. Locate the internal SCSI connector on the power backplane.
2. Use the 16-bit two-drop SCSI cable located in the bottom of the server media bay.

Review the information in “Before you begin” on page 58.
All the DIMMs installed in each set must be the same size and speed, but all the
sets do not have to contain DIMMs of the same size and speed.
•
•
The memory board contains 16 DIMM connectors and supports 4-way memory
interleaving.
Install only 3.3 V, 168-pin, 8-byte, registered DIMMs. Only 100 MHz, 72-bit,
registered, synchronous, error correcting code (ECC), SDRAM configuration
DIMM memory is supported for the 128 MB, 256 MB, 512 MB and 1 GB (when
available) DIMMs.
•
•
•
If you install 4 GB of memory, some of the memory is reserved for system
resources. The amount reserved for system resources depends on the
configuration of the server.
If you install 16 GB of memory, the Configuration/ Setup Utility will display the
memory that is usable by the network operating system. This amount of memory
might differ from the amount of memory you have installed.
Installing or removing DIMMs changes the configuration information in the
server. Therefore, after installing or removing a DIMM, you must save the new
configuration information in the Configuration/ Setup Utility program. Refer to
information.

Ultra2 (LVD) SCSI ports
The server supports an optional IBM ServeRAID controller. This controller provides
three independent SCSI channels. A 16-bit (wide) LVD SCSI cable connects the hard
disk drive backplane to one channel of the RAID controller. Two 68-pin SCSI
The server has a dual-channel Ultra-2 small computer system interface (SCSI)
controller. This controller supports two independent SCSI channels: one external and
one internal. Each of these channels supports up to 15 SCSI devices. You can use the
external LVD SCSI channel connector, on the rear of the server, to connect different
types of SCSI devices, such as drives or printers.
SCSI cabling requirements
If you plan to attach external SCSI devices, you must order additional SCSI cables. To
select and order the correct cables for use with external devices, contact your IBM
reseller or IBM marketing representative.
For information about the maximum length of SCSI cable between the terminated
ends of the cable, refer to the ANSI SCSI standards. Adhering to these standards will
help ensure that the server operates properly.
Setting SCSI IDs
Each SCSI device connected to a SCSI controller must have a unique SCSI ID. This ID
enables the SCSI controller to identify the device and ensure that different devices on
the same SCSI channel do not attempt to transfer data simultaneously. SCSI devices
that are connected to different SCSI channels can have duplicate SCSI IDs. SCSI IDs 6
and 7 are reserved for the SCSI controller on either SCSI channel A or B. The following
table lists the SCSI IDs for devices that are connected to one channel. In Table 14 on
page 98, the hot-swap hard disk drive bays are in the standard (vertical)
configuration.

Serial ports
The server has two standard serial ports: Serial port A and Serial port B. The
operating system can use and share both serial ports; however, the integrated
Advanced System Management Processor can use and share only Serial port A.
Some application programs require specific ports, and some modems function
properly only at certain communication port addresses. You might need to use the
Configuration/ Setup Utility program to change communication port address
assignments to prevent or resolve address conflicts.
Viewing or changing the serial-port assignments
To view or change the serial-port assignments:
1. Restart the server and watch the monitor screen.
2. When the message Press F1 for Configuration/Setupappears, press F1.
3. From the main menu, select Devices and I/O Ports; then, press Enter.
Note: The Devices and I/ O Ports choice appears only on the full configuration
menu. If you set two levels of passwords, you must enter the
administrator password to access the full configuration menu.
4. Select the serial port; then, use the arrow keys to advance through the settings
available.
5. Select Save Settings; then, select Exit Setup to exit from the Configuration/ Setup
Utility main menu.

Universal Serial Bus ports
The server has two Universal Serial Bus (USB) ports that configure automatically.
USB is an emerging serial interface standard for telephony and multimedia devices. It
uses Plug and Play technology to determine the type of device attached to the
connector.
Notes:
1. If you attach a standard (non-USB) keyboard to the keyboard connector, the USB
ports and devices will be disabled during the power-on self-test (POST).
2. If you install a USB keyboard that has a mouse port, the USB keyboard emulates a
mouse and you will not be able to disable the mouse settings in the
Configuration/ Setup Utility program.
3. Check to make sure your NOS supports USB devices.
USB cables and hubs
You need a 4-pin cable to connect devices to USB 1 or USB 2. If you plan to attach
more than two USB devices to the machine, you must use a hub to connect the
devices. The hub provides multiple connectors for attaching additional external USB
devices with a maximum of 127 external devices.
USB technology provides up to 12 megabits-per-second (Mbps) speed with a
maximum of 127 external devices and a maximum signal distance of five meters (16
ft.) per segment.
USB-port connectors
Each USB port has an external connector on the rear of the server for attaching USB
compatible devices.

Ethernet port
Your server comes with an integrated Ethernet controller. This controller provides an
interface for connecting to 10-Mbps or 100-Mbps networks and provides full-duplex
(FDX) capability, which enables simultaneous transmission and reception of data on
the Ethernet local area network (LAN).
To access the Ethernet port, connect a Category 3, 4 or 5 unshielded twisted-pair
(UTP) cable to the RJ-45 connector on the rear of the server.
100 Hardware Maintenance Manual: xSeries 250
Download from Www.Somanuals.com. All Manuals Search And Download.
Note: The 100BASE-TX Fast Ethernet standard requires that the cabling in the
network be Category 5 or higher.
Configuring the Ethernet controller
When you connect the server to the network, the Ethernet controller automatically
detects the data-transfer rate (10Mbps or 100Mbps) on the network and then sets the
controller to operate at the appropriate rate. That is, the Ethernet controller will
adjust to the network data rate, whether the data rate is standard Ethernet (10BASE-
T), Fast Ethernet (100BASE-TX), half duplex (HDX), or full duplex (FDX). The
controller supports half-duplex (HDX) and full-duplex (FDX) modes at both speeds.
The Ethernet controller is a PCI Plug and Play device. You do not need to set any
jumpers or configure the controller for the operating system before you use the
Ethernet controller. However, you must install a device driver to enable the operating
system to address the Ethernet controller. The device drivers are provided on the
ServerGuide CDs.
Failover for redundant Ethernet
The IBM 10/ 100 Fault Tolerant Adapter is an optional redundant network interface
card (NIC adapter) that you can install in the server. If you install this NIC adapter
and connect it to the same logical LAN segment as the primary Ethernet controller,
you can configure the server to support a failover function. You can configure either
the integrated Ethernet controller or the NIC adapter as the primary Ethernet
controller. In failover mode, if the primary Ethernet controller detects a link failure,
all Ethernet traffic associated with it is switched to the redundant (secondary)
controller. This switching occurs without any user intervention. When the primary
link is restored to an operational state, the Ethernet traffic switches back to the
primary Ethernet controller. The switch back to the primary Ethernet controller can be
automatic or manually controlled, depending on the setup and operating system.
Note that only one controller in the redundant pair is active at any given time. For
example, if the primary Ethernet controller is active, then the secondary Ethernet
controller cannot be used for any other network operation.
Note: The operating system determines the maximum number of IBM 10/ 100 Fault
Tolerant Adapters that you can install in the server. See the documentation
that comes with the adapter for more information.
Considerations when combining failover and hot-plug
functions: If the operating system supports hot-plug PCI adapters and the optional
redundant NIC adapter is installed in a hot-plug PCI slot, you can replace the NIC
adapter without powering off the server — even if it is the primary Ethernet
controller. Disconnecting the Ethernet cable from the primary Ethernet controller will
cause the Ethernet traffic to switch automatically to the secondary Ethernet controller.
This can be very useful if a faulty adapter causes a network problem, or if you want to
upgrade the primary adapter hardware.
Note: If you hot replace the primary adapter while the Ethernet traffic is being
handled by the secondary Ethernet controller, the traffic does not
automatically switch back to the primary adapter when the primary adapter
comes back online. See “Configuring for failover”.
Configuring for failover: The failover feature currently is supported by OS/ 2™,
Windows NT Server, and IntraNetWare. The setup required for each operating
system follows.
Windows NT Server: IBM offers hot-plug support for Windows NT Server Version 4.0.
Failover can work in conjunction with hot-plug support or independently. If you are
not using hot-plug support, go to “Windows NT Server failover setup” on page 102.

Windows NT Server hot-plug setup: IBM Hot Plug PCI for Windows NT Server 4.0
package is available for download from the IBM Web site at:
http://www.pc.ibm.com/support
Enter the brand type of Server, click on Downloadable files and look for Hot Plug.
The IBM Hot Plug PCI for Windows NT Server 4.0 package uses the Intel Desktop
Management Interface (DMI) to control hot-plug support for the Ethernet controllers.
The Ethernet controller in the computer is DMI compliant. Download and install the
following software in the order listed:
1. IBM PCI Hotplug for Windows NT 4.0 Failover DMI Agent
2. IBM PCI Hot Plug for Windows NT 4.0 Solution
3. IBM 10/ 100 Fault Tolerant Adapter device drivers
Note: The order of installation is important. You must install the IBM Hot Plug for
Windows NT Server 4.0 package before you install the IBM 10/ 100 Fault
Tolerant Adapter driver. If you install the adapter device driver before the PCI
Hot Plug Solution package, the adapter device driver will not recognize the
hot-plug code. This happens because the adapter device driver only checks
the NT registry for the Hot Plug package during installation. If the PCI Hot
Plug Solution package is added after the adapter device driver is installed, the
adapter must be removed and added again in order for it to detect the PCI
Hot-Plug Solution code.
To install the IBM PCI Hotplug for Windows NT 4.0 Failover DMI Agent:
1. Download the IBM PCI Hotplug for Windows NT 4.0 Failover DMI Agent DMI
Agent file from the Support web page and extract the files onto a diskette.
2. Insert the diskette into the diskette drive.
3. From the Start menu, select the Run option.
4. Type A:\ SETUP.EXE in the Open box.
5. Click Ok. The setup wizard opens.

support web page and extract the files onto a diskette.
2. Log on to Windows NT Server as a user in the Administrator group.
3. Insert the diskette into the diskette drive.
4. From the Start menu, select the Run option.
5. Type A:\ SETUP.EXE in the Open box.
6. Click OK. The Setup wizard opens.
7. Follow the instructions given by the setup wizard until the program is installed.
Windows NT Server failover setup: To install the IBM 10/ 100 Fault Tolerant Adapter
device drivers:
1. Add the redundant NIC adapter according to the instructions that are provided
with the adapter.
2. Use the ServerGuide CDs to install the AMD PCNet Ethernet Family adapter
device driver.
3. Do not select the Grouping box at this point; you must first restart the machine.

4. From the Windows NT Server desktop, select Control Panel, then select the
Network icon, then select the Adapters tab.
5. Highlight one of the adapters that will be in the redundant pair and then click the
Properties... button.
6. Check the Grouping box. This will show the possible combinations for redundant
pairs.
7. Select the adapter pair you want and then select OK. Note that the integrated
Ethernet controller is located at PCI C.
Two options are available for recovering from a failover condition. The options
are determined by the Enable for DMI / Hot Swap Support checkbox. If the IBM
Hot Plug PCI for Windows NT Server 4.0 package is installed, this checkbox will
appear at the bottom of the Adapter Properties panel. If you do not have the IBM
Hot Plug PCI for Windows NT Server 4.0 package installed on the server, you will
not see the Enable for DMI / Hot Swap Support checkbox.
If the Enable for DMI / Hot Swap Support checkbox is not checked or is not
present, traffic will automatically switch back to the primary adapter when the
primary link status is restored. In this mode, the adapter cannot be hot-swapped.
Users with the IBM Hot Plug PCI for Windows NT Server 4.0 package installed
should check the Enable for DMI / Hot Swap Support checkbox.
If the Enable for DMI / Hot Swap Support checkbox is checked, traffic will
remain on the secondary adapter until the user directs it to return to the primary
adapter. This can be done after the hot-swap replacement of the primary adapter
or by using the DMI interface.
8. Select Close to exit from the Network setup.
When you restart the server, the failover function will be in effect.
If a failover occurs, a message is written to the NT Event Viewer log. In addition, if
the Enable for DMI / Hot Swap Support checkbox is checked, a DMI alert will also be
generated.
IntraNetWare: The IBM PCI Hot Plug System Bus Driver Diskette for Novell Netware
V4.41, V4.42, and V5.0 is available for download from the IBM Web site at:
http:/ / www.pc.ibm.com/ support
The failover function is now enabled. If a failover occurs:
•
•
The operating system console generates a message.
The custom counters for the device driver contain variables that define the state of
the failover function and the location of the redundant pair. You can use the
NetWare Monitor to view the custom counters.
Note: If the primary adapter was hot-replaced while the Ethernet traffic was being
handled by the secondary Ethernet controller, the traffic does not
automatically switch back to the primary adapter when the primary adapter
comes back online. In this case, issue the command:
LOAD d:\path\PCNTNW SCAN
where d and path are the drive and path where the driver is located. This
command causes the device driver to locate the primary adapter and switch
the Ethernet traffic to it.

Advanced System Management ports
Your server has three communication ports dedicated to the Advanced System
Management Processor. One port uses a standard D-shell serial-port connector,
connector C. The other two ports, which are used for the ASM Interconnect function,
use a dual RJ-45 connector.
You can attach a dedicated modem to the D-shell system-management connector on
the rear of the server to communicate with the integrated Advanced System
Management Processor.
The ASM Interconnect function uses the RJ-45 system-management connectors. This
function enables you to connect the Advanced System Management Processors of
several rack-mounted servers so that they can communicate with each other in half-
duplex mode.

Using IBM ServeRAID
The following information is for configuring an IBM ServeRAID-3H, ServeRAID-
3HB, or ServeRAID-3L. These high-performance, redundant array of independent
disk (RAID) controllers are ideally suited for data-storage environments that require
superior performance, flexibility, and reliable data storage.
You also can use the configuration and reference information in this chapter to
configure the IBM ServeRAID controllers provided on some IBM server system
boards.
Understanding RAID technology
RAID is the technology of grouping several physical drives in a computer into an
array that you can define as one or more logical drives. Each logical drive appears to
the operating system as a single drive. This grouping technique greatly enhances
logical-drive capacity and performance beyond the physical limitations of a single
physical drive.
When you group multiple physical drives into a logical drive, the ServeRAID
controller can transfer data in parallel from the multiple drives in the array. This
parallel transfer yields data-transfer rates that are many times higher than with
nonarrayed drives. This increased speed makes the system better able to meet the
throughput (the amount of work in a given amount of time) or productivity needs of
the multiple-user network environment.
The ability to respond to multiple data requests provides not only an impressive
increase in throughput, but also a decrease in response time. The combination of
parallel transfers and simultaneous responses to multiple requests allows disk arrays
to provide a high level of performance in network environments.
Stripe-unit size
With RAID technology, data is striped across an array of physical drives. This data-
distribution scheme complements the way the operating system requests data.
The granularity at which data is stored on one drive of the array before subsequent
data is stored on the next drive of the array is called the stripe-unit size.
You can control the stripe-unit size and maximize the performance of the ServeRAID
controller by setting a stripe-unit size to a value that is close to the size of the system
I/ O requests. You can set the stripe-unit size to 8 KB, 16 KB, 32 KB, or 64 KB. For
example, performance in transaction-based environments, which typically involve
large blocks of data, might be optimal when the stripe-unit size is set to 32 KB or 64
KB; however, performance in file and print environments, which typically involve
multiple small blocks of data, might be optimal when the stripe-unit size is set to 8 KB
or 16 KB.
The collection, in logical order of these stripe units, from the first drive of the array to
the last drive of the array, is called a stripe.
Note: If you are using the ServeRAID-3L:

•
Eight physical drives are supported in an array if the stripe-unit size is set
to 32 KB or 64 KB.
Sixteen physical drives are supported in an array if the stripe-unit size is
set to 8 KB or 16 KB.
If you are using the ServeRAID-3H or ServeRAID-3HB, sixteen physical drives
are supported in an array if the stripe-unit size is set to 32 KB or 64 KB.
Supported RAID levels
Disk arrays are used to improve performance and reliability. The amount of
improvement depends on the application programs that you run on the server, the
RAID levels that you assign to the logical drives, and the stripe-unit size.
The ServeRAID controllers support RAID level-0, RAID level-1, RAID level-1
Enhanced (1E), RAID level-5 and RAID level-5 Enhanced (5E).
Understanding RAID level-0
RAID level-0 stripes the data across all the drives in the array. This offers substantial
speed enhancement, but provides for no data redundancy. RAID level-0 provides the
largest capacity of the RAID levels offered, because no room is taken up for redundant
data or data-parity storage.
RAID level-0 requires a minimum of one drive and, depending upon the level of
firmware and the stripe-unit size, supports a maximum of eight or 16 drives.
The following illustration shows an example of a RAID level-0 logical drive.
You start with two physical drives.
Create an array using the two physical drives.
Then, create a logical drive within that array.

The data is striped across the drives, creating blocks. Notice that the data is striped
across all the drives in the array, but no redundant data is stored.

A physical drive failure within the array results in loss of data in the logical drive
assigned RAID level-0, but only in that logical drive. If you have logical drives
assigned RAID level-1, 1E, 5, or 5E in the same array, they will not lose data.
Note: You can assign RAID level-0 only to logical drives in an array that contains
only one physical drive.
When you replace a failed drive, the ServeRAID controller can rebuild all the RAID
level-1E and RAID level-5E logical drives automatically onto the replacement
physical drive. However, any data stored in a failed RAID level-0 logical drive is lost.
Though the risk of data loss is present, you might want to assign RAID level-0 to one
of the logical drives to take advantage of the speed offered with this RAID level. You
could use this logical drive to enter data that you back up each day and for which
safety is not of primary importance, that is, data that you can re-create easily. You also
might want to use a RAID level-0 logical drive when the work you are doing requires
maximum drive capacity.
Understanding RAID Level-1
RAID level-1 provides 100% data redundancy and requires only two physical drives.
With RAID level-1, the first half of a stripe is the original data; the second half of a
stripe is a mirror (that is, a copy) of the data, but written to the other drive in the RAID
level-1 array.
Because the data is mirrored, the capacity of the logical drive when assigned RAID
level-1 is 50% of the array capacity.
The following illustration shows an example of a RAID level-1 logical drive.
You start with two physical drives.
Using IBM ServeRAID 119

Create an array using the two physical drives.
Then, create a logical drive within that array.
The data is striped across the drives, creating blocks. Notice that the data on the drive
on the right is a mirror copy of the drive on the left.

With RAID level-1, if one of the physical drives fails, the ServeRAID controller
switches read and write requests to the remaining functional drive in the RAID level-
1 array.
Understanding RAID Level-1 Enhanced
If you have three or more physical drives in the array, you can no longer select RAID
level-1, but you can select RAID level-1 Enhanced (also called RAID level-1E).
RAID level-1E combines mirroring with data striping. This RAID level stripes data
and copies of the data across all of the drives in the array. As with the standard RAID

level-1, the data is mirrored, and the capacity of the logical drive is 50% of the array
capacity of the grouping of physical drives in the array.
RAID level-1E requires a minimum of three drives and, depending upon the level of
firmware and the stripe-unit size, supports a maximum of eight or 16 drives.
The following illustration is an example of an Enhanced RAID level-1 logical drive.
You start with three physical drives.
Create an array using the physical drives.
Then, create a logical drive within that array.
The data is striped across the drives, creating blocks. Notice that the stripe labeled ꢀꢀ
is the data stripe and the stripe labeled ꢀ ꢀ is the mirror (that is, the copy) of the
preceding data stripe. Also notice that each block on the mirror stripe is shifted one
drive.

With RAID level-1E, if one of the physical drives fails, the ServeRAID controller
switches read and write requests to the remaining functional drives in the RAID level-
1E array.
Understanding RAID Level-5
RAID level-5 requires a minimum of three physical drives. This RAID level stripes
data and parity across all drives in the array. When an array is assigned RAID level-5,
the capacity of the array is reduced by one drive (for data-parity storage).
RAID level-5 is generally the most desirable choice, because it offers both data
protection and increased throughput. RAID level-5 gives you higher capacity than
RAID level-1, but RAID level-1 offers better performance.
The RAID level-5 requires a minimum of three drives and, depending upon the level
of firmware and the stripe-unit size, supports a maximum of eight or 16 drives.
The following illustration is an example of a RAID level-5 logical drive.
You start with four physical drives.
x
Create an array using three of the physical drives, leaving the fourth as a hot-spare
drive.
x
Then, create a logical drive within that array.
x
The data is striped across the drives, creating blocks. Notice that the storage of the
data parity (denoted by ꢀ ) also is striped, and it shifts from drive to drive.

Understanding RAID Level-5 Enhanced
RAID level-5 Enhanced (also called RAID level-5E) requires a minimum of four
physical drives. RAID level-5E is also firmware-specific. You can think of RAID level-
5E as "RAID level-5 with a built-in spare drive."
Reading from and writing to four disk drives is more efficient than three disk drives
and an idle hot spare and therefore improves performance. Additionally, the spare
drive is actually part of the RAID level-5E array, as shown in the following example.
With such a configuration, you cannot share the spare drive with other arrays. If you
want a spare drive for any other array, you must have another spare drive for those
arrays.
Like RAID level-5, this RAID level stripes data and parity across all of the drives in
the array. When an array is assigned RAID level-5E, the capacity of the logical drive is
reduced by the capacity of two physical drives in the array (that is, one for parity and
one for the spare).
RAID level-5E is a very desirable choice, because it offers both data protection and
increased throughput, in addition to the built-in spare drive.
Note: For RAID level-5E, you can have only one logical drive in an array. When
using RAID level-5E, you can have a maximum of seven logical drives on the
controller.
RAID level-5E requires a minimum of four drives and, depending upon the level of
firmware and the stripe-unit size, supports a maximum of eight or 16 drives.
The following illustration is an example of a RAID level-5E logical drive.
You start with four physical drives.

Create an array using all four physical drives.
Then, create a logical drive (labeled as 1) within the array. Notice that the distributed
spare drive is the free space (labeled as 2) below the logical drive.

The data is striped across the drives, creating blocks in the logical drive. The storage
of the data parity (denoted by ) is striped, and it shifts from drive to drive as it does

in RAID level-5. Notice that the spare drive is not striped.

If a physical drive fails in the array, the data from the failed drive is compressed into
the distributed spare drive. The logical drive remains RAID level-5E. When you
replace the failed drive, the data for the logical drive decompresses and returns to the
original striping scheme.

Physical drive state descriptions
The following table provides descriptions of the valid physical drive states.
Drive State
Defunct
Meaning
A physical drive in the Online, Hot-Spare, or Rebuild state has become defunct. It does not
respond to commands, which means that the ServeRAID controller cannot communicate
properly with the drive.
Hot Spare
A Hot-Spare drive is a physical drive that is defined for automatic use when a similar drive
fails.
Online
The drive is Online. It is functioning properly and is part of an array.
The drive is being rebuilt.
Rebuilding
Ready
The ServeRAID controller recognizes a Ready drive as being available for definition.
Standby Hot Spare
A Standby Hot Spare is a Hot-Spare drive that the ServeRAID controller has spun down. If
an Online drive becomes Defunct and no suitable Hot-Spare drive is available, a Standby
Hot-Spare drive of the appropriate size automatically spins up, and enters the Rebuild state.
Logical drive state descriptions
The following table provides descriptions of the valid logical drive states.
Drive State
Meaning
Blocked
During a rebuild operation, the ServeRAID controller sets the state of any RAID level-0 logical
drives associated with a failed array to the Blocked state; then, it reconstructs the data that was
stored in RAID level-1, RAID level-1E, Raid level-5 and RAID level-5E logical drives.
After the Rebuild operation completes, you can unblock the RAID level-0 logical drives, and
access them once again. However, the logical drive might contain damaged data. You must
either re-create, reinstall, or restore the data from the most recent backup disk or tape to the
RAID level-0 logical drive.
Critical Migrating
Critical System
A logical drive in the critical state that is undergoing a logical drive migration (LDM).
The ServeRAID controller uses this reserved state during a logical drive migration (LDM)
when the logical drive is in the critical state.
Critical
A RAID level-1, RAID level-1E, RAID level-5, or RAID level-5E logical drive that contains a
defunct physical drive is in the critical state. A critical logical drive is accessible, despite a
physical drive failure.
Attention:
Migrating
The logical drive is undergoing a logical drive migration; that is, a change in RAID levels, a
change in logical drive size, an increase in free space, or a RAID level-5E compression or
decompression.
126 Hardware Maintenance Manual: xSeries 250
Download from Www.Somanuals.com. All Manuals Search And Download.
Drive State
Offline
Meaning
The logical drive is offline and not accessible. This state occurs when one of the following is
true.
•
•
One or more physical drives in a RAID level-0 logical drive is defunct.
Two or more physical drives in a RAID level-1, RAID level-1E, or level-5 logical drive are
defunct.
•
Three or more drives in a RAID level-5E logical drive are defunct.
If any of these are true, refer to “Rebuilding a defunct drive” on page 23.
The logical drive is okay. It is in a good, functional state.
Okay
System
The ServeRAID controller uses this reserved state during logical drive migration (LDM).

Using utility programs
This section provides the information needed to start and use the FlashMan program,
the ServeRAID Mini-Configuration program, and the IPSSEND and IPSMON
command-line programs.
Using FlashMan, the IBM ServeRAID ROM Update
program
FlashMan is an easy to use program that simplifies the updating of BIOS and
firmware on ServeRAID controllers. FlashMan reports the current BIOS version,
firmware version, and update status for each controller found. FlashMan also reports
if a controller needs updating. You decide whether or not to update the controllers,
but you must update all the controllers or none (that is, you cannot selectively
update).
FlashMan is provided on the IBM ServeRAID Support CD packaged with the
ServeRAID controller, and it also is provided on the configuration CD packaged with
some IBM server models.
To access FlashMan:
1. Insert the IBM ServeRAID Support CD into the system CD-ROM drive.
Using IBM ServeRAID 129
Download from Www.Somanuals.com. All Manuals Search And Download.
2. Turn on the system.
3. The FlashMan splash screen appears. FlashMan automatically scans and
identifies each ServeRAID controller in the system. After scanning completes and
if an update is required, a report screen appears with the following information:
•
•
•
•
•
Controller types found
Controller slot number, if known
Firmware version
BIOS version
Update status. If a controller has down-level BIOS or firmware, the controller
is marked as a candidate for update.
4. If any of the ServeRAID controller require updating, click Update to update all
marked ServeRAID controllers. The controller BIOS or firmware is updated from
the IBM ServeRAID Support CD or IBM ServeRAID Device Driver Diskette.
FlashMan displays a progress indicator as it updates the controllers. If FlashMan
detects an error, it displays the error message and saves the error message to a file
on the disk.
If you do not want to update the ServeRAID controllers, click Cancel.
5. When all updates are complete, scroll through the New Feature window. This
window reports the changes that FlashMan applied to the ServeRAID controllers.
Note: When the splash screen appears, you can use Ctrl+L to copy all updated files
to the RAMDISK. Use this keystroke only when instructed by IBM Support.
Using the ServeRAID Mini-Configuration program
The ServeRAID Mini-Configuration program is a quick way to display the current

Be careful when making selections from this menu. If you change the configuration,
you might lose data.
•
Restore to Factory Default Settings is used to reset the configuration. When you
reset the configuration, you will not have access to any data stored on the logical
drives attached to the selected ServeRAID controller.
This choice deletes the existing configuration information, sets all functional
physical drives attached to the controller to the Ready state, and deletes all logical
drives defined for the controller.
This choice does not change any of the ServeRAID controller settings (such as the
stripe-unit size, rebuild rate, and so on) from their current or customized values.
•
•
Copy the Configuration from Drives to Controller reads the most common
configuration from the drives in the system and copies it to the ServeRAID
controller.
Configure BIOS Settings is used to modify the BIOS settings, such as the
Bootable CD-ROM setting, for the ServeRAID controller. (See “Setting the
Bootable CD-ROM feature” for more information.)
Note: The Multiple Controller mode for extra BIOS has two settings: Erase and
Shrink. When this parameter is set to Erase, redundant copies of the
ServeRAID BIOS are erased. When this parameter is set to Shrink, the
redundant copies of the ServeRAID BIOS are removed from memory but
stored in the controller for future use. When you have multiple ServeRAID
controllers installed, you need only one active copy of ServeRAID BIOS.
However, to ensure that you have a copy of the ServeRAID BIOS available
if your active copy becomes defective or unavailable, leave the Multiple
Controller parameter set to Shrink.
•
•
View Controller and PCI Information shows the ServeRAID controller hardware
and PCI register information.
Exit is used to exit from the Mini-Configuration program.
Setting the Bootable CD-ROM feature: When you attach a CD-ROM drive to the
ServeRAID controller and set the Bootable CD-ROM feature to Yes, the ServeRAID
controller will attempt to start a CD that has a bootable startup partition, if no other
controller in the system is currently using INT13 extensions. Only one controller in the
system can support the INT13 extensions.
To enable the Bootable CD-ROM feature:
1. Select Advanced Functions from the Main Menu of the Mini-Configuration
program.

/usr/bin/ipsmon
2. Press Enter.
Using the IPSMON program
When you start the IPSMON monitoring program, it immediately begins polling all
ServeRAID controllers for specific conditions. If a condition being monitored is
found, this program logs a message to the screen, to a file, or to both the screen and a
file.
Supported operating systems: Windows NT, OS/ 2, NetWare, Linux, OpenServer,
UnixWare
Command:
ipsmon options
where:
•
options is one of the following optional parameters:
— -F:filename to specify the name of the file in which to record messages. The
default file name is IPSMON.LOG.
— -S to display messages on the standard output (usually the monitor)
— -? to obtain a current list of valid parameters
Note: If you start this program without any command-line parameters, the
IPSMON program will log the messages to the IPSMON.LOG file, and the
messages will not appear on the screen.
After you start the IPSMON program, the program will continuously poll the
ServeRAID controllers until you take one of the following actions:
•
•
•
If you are using Windows NT or OS/ 2, press Ctrl+C.
If you are using NetWare, type unload ipsmonat the system console.
If you are using OpenServer or UnixWare, press the Del key to cancel the
program.
During operation, the program will log various messages. Each message will contain
an alert code and a location specifier.
•
The alert code begins with the message type and number; for example, INF,
WRN, or CRT (followed by the message number).
•
The location specifier comes after the alert code:
A followed by the controller number
SID followed by the SCSI ID (if required)
C followed by the channel number (if required)
For example, a message of CRTxxx:A2C3SID04signifies that a Critical condition
(CRTxxx) was found on Controller 2 (A2), Channel 3 (C3), SCSI ID 4 (SID04).

Symptom-to-FRU index
This index supports xSeries 250 servers.
Notes:
1. Check the configuration before you replace a FRU. Configuration problems can
cause false errors and symptoms.
2. The default configuration can be loaded by starting the system and then pressing
the reset button four times, waiting 15 seconds between each press. Once the
configuration has reset to the default, it must be saved in Setup to be stored in
CMOS.
3. For IBM devices not supported by index, refer to the manual for that device.
The Symptom-to-FRU lists symptoms, errors, and the possible causes. The most
likely cause is listed first. Use this Symptom-to-FRU index to help you decide which
FRUs to have available when servicing the computer. The POST BIOS displays POST
error codes and messages on the screen.
Beep symptoms
Beep symptoms are short tones or a series of short tones separated by pauses
(intervals without sound). See the following examples.

ServeRAID POST (ISPR) error procedures
The ISPR Error Procedures list errors, symptoms, and the possible causes. The most
probable cause is listed first. Use these procedures to help you solve ServeRAID
problems when servicing the computer.
EF10 (Default ISPR)
1. No ISPR Error Present.
1XXX (Microcode Checksum Error)
1. Replace the ServeRAID controller.
2XXX thru 5XXX (Code DRAM Error)
1. Install two download jumpers parallel to the PCI slots. For jumper locations, see
2. Flash the controller with the latest IBM ServeRAID BIOS/ Firmware from the IBM
Website.
3. Remove the jumpers.
4. If the error persists, replace ServeRAID controller.
6XXX (Cache DRAM Error)
1. Reseat Cache Memory SIMM.
2. Install two download jumpers parallel to the PCI slots. For jumper locations, see
3. Flash the controller with the latest IBM ServeRAID BIOS/ Firmware from the IBM
Website.
4. Remove the jumpers.
5. If the error persists, replace ServeRAID controller.
7XXX thru 8XXX (Host/ Local PCI Bus Interface Error)
1. Install two download jumpers parallel to the PCI slots. For jumper locations,
2. Flash the controller with the latest IBM ServeRAID BIOS/ Firmware from the IBM
Website.
3. Remove the jumpers.
4. If the error persists, replace ServeRAID controller.
9XXX thru BXXX (SCSI bus error caused either by defective drives, termination, etc.)
1. Isolate between SCSI subsystem and controller by disconnecting all SCSI cables
from suspect card, and reboot.
CAUTION:
Do not press F5. Doing so changes the customer’s configuration.
If an ISPR error is still present, perform the following actions until the error is no
longer present:
a. Reseat the controller.
b. Replace the controller.
Notes:
a. The controller detects a configuration change. Do not choose Save
Changes.Instead, press F10 to bypass any options to this effect.
2. If ISPR error is EF10 after disconnecting cables:
162 Hardware Maintenance Manual: xSeries 250
Download from Www.Somanuals.com. All Manuals Search And Download.
a. Identify which channel is causing the error by the second digit of the original
ISPR code:
ISPR = B1xx = Channel 1
ISPR = B2xx = Channel 2
ISPR = B3xx = Channel 1 and 2
ISPR = B4xx = Channel 3
ISPR = B5xx = Channel 1 and 3
ISPR = B6xx = Channel 2 and 3
ISPR = B7xx = Channel 1, 2 and 3
ISPR = BFxx = Channel not identified
b. Confirm that the channel(s) identified from the error in step 2 is(are) the cause
of the error by verifying that the error presents itself ONLY when the
offending channel is reconnected.
c. Check termination of identified channel.
d. Check for proper backplane jumper configuration.
e. Check for proper cabling configuration in systems that use DASD status
cables. Reconnect all cables removed in step 1 above.
f. Disconnect one drive at a time attached to the channel identified in step 2a,

Safety information
The following section contains the safety information that you need to be familiar
with before servicing an IBM mobile computer.
General safety
Follow these rules to ensure general safety:
•
Observe good housekeeping in the area of the machines during and after
maintenance.
•
When lifting any heavy object:
1. Ensure you can stand safely without slipping.
2. Distribute the weight of the object equally between your feet.
3. Use a slow lifting force. Never move suddenly or twist when you attempt to
lift.
4. Lift by standing or by pushing up with your leg muscles; this action removes
the strain from the muscles in your back. Do not attempt to lift any objects that
weigh more than 16 kg (35 lb) or objects that you think are too heavy for you.
•
•
•
•
•
Do not perform any action that causes hazards to the customer, or that makes the
equipment unsafe.
Before you start the machine, ensure that other service representatives and the
customer's personnel are not in a hazardous position.
Place removed covers and other parts in a safe place, away from all personnel,
while you are servicing the machine.
Keep your tool case away from walk areas so that other people will not trip over
it.
Do not wear loose clothing that can be trapped in the moving parts of a machine.
Ensure that your sleeves are fastened or rolled up above your elbows. If your hair
is long, fasten it.
•
•
Insert the ends of your necktie or scarf inside clothing or fasten it with a
nonconductive clip, approximately 8 centimeters (3 inches) from the end.
Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your
clothing.
Remember: Metal objects are good electrical conductors.
•
Wear safety glasses when you are: hammering, drilling soldering, cutting wire,
attaching springs, using solvents, or working in any other conditions that might
be hazardous to your eyes.

hazardous. To avoid personal injury or equipment damage, disconnect the attached
power cords, telecommunication systems, networks, and modems before you open
the server covers, unless instructed otherwise in the installation and configuration
procedures.
Observe the following rules when working on electrical equipment.
Important: Use only approved tools and test equipment. Some hand tools have
handles covered with a soft material that does not insulate you when
working with live electrical currents.
Many customers have, near their equipment, rubber floor mats that
contain small conductive fibers to decrease electrostatic discharges. Do
not use this type of mat to protect yourself from electrical shock.
•
Find the room emergency power-off (EPO) switch, disconnecting switch, or
electrical outlet. If an electrical accident occurs, you can then operate the switch
or unplug the power cord quickly.
•
•
Do not work alone under hazardous conditions or near equipment that has
hazardous voltages.
Disconnect all power before:
— Performing a mechanical inspection
— Working near power supplies
— Removing or installing main units
•
•
Before you start to work on the machine, unplug the power cord. If you cannot
unplug it, ask the customer to power-off the wall box that supplies power to the
machine and to lock the wall box in the off position.
If you need to work on a machine that has exposed electrical circuits, observe the
following precautions:
— Ensure that another person, familiar with the power-off controls, is near you.
Remember: Another person must be there to switch off the power, if
necessary.
— Use only one hand when working with powered-on electrical equipment;
keep the other hand in your pocket or behind your back.
Remember: There must be a complete circuit to cause electrical shock. By
observing the above rule, you may prevent a current from passing through
your body.
— When using testers, set the controls correctly and use the approved probe
leads and accessories for that tester.
— Stand on suitable rubber mats (obtained locally, if necessary) to insulate you
from grounds such as metal floor strips and machine frames.
Observe the special safety precautions when you work with very high voltages;
these instructions are in the safety sections of maintenance information. Use
extreme care when measuring high voltages.
•
Regularly inspect and maintain your electrical hand tools for safe operational
condition.
•
•
Do not use worn or broken tools and testers.
Never assume that power has been disconnected from a circuit. First, check that it
has been powered-off.
•
Always look carefully for possible hazards in your work area. Examples of these
hazards are moist floors, nongrounded power extension cables, power surges,
and missing safety grounds.

•
•
Do not touch live electrical circuits with the reflective surface of a plastic dental
mirror. The surface is conductive; such touching can cause personal injury and
machine damage.
Do not service the following parts with the power on when they are removed
from their normal operating places in a machine:
— Power supply units
— Pumps
— Blowers and fans
— Motor generators
and similar units. (This practice ensures correct grounding of the units.)
If an electrical accident occurs:
•
— Use caution; do not become a victim yourself.
— Switch off power.
— Send another person to get medical aid.
Safety inspection guide
The intent of this inspection guide is to assist you in identifying potentially unsafe
conditions on these products. Each machine, as it was designed and built, had
required safety items installed to protect users and service personnel from injury. This
guide addresses only those items. However, good judgment should be used to
identify potential safety hazards due to attachment of non-IBM features or options not
covered by this inspection guide.
If any unsafe conditions are present, you must determine how serious the apparent
hazard could be and whether you can continue without first correcting the problem.
Consider these conditions and the safety hazards they present:
•
Electrical hazards, especially primary power (primary voltage on the frame can
cause serious or fatal electrical shock).
•
•
Explosive hazards, such as a damaged CRT face or bulging capacitor
Mechanical hazards, such as loose or missing hardware
The guide consists of a series of steps presented in a checklist. Begin the checks with
the power off, and the power cord disconnected.
Checklist:
1. Check exterior covers for damage (loose, broken, or sharp edges).
2. Power-off the computer. Disconnect the power cord.
3. Check the power cord for:
a. A third-wire ground connector in good condition. Use a meter to measure
third-wire ground continuity for 0.1 ohm or less between the external ground
pin and frame ground.
b. The power cord should be the appropriate type as specified in the parts
listings.
c. Insulation must not be frayed or worn.
4. Remove the cover.
5. Check for any obvious non-IBM alterations. Use good judgment as to the safety
of any non-IBM alterations.
182 Hardware Maintenance Manual: xSeries 250
Download from Www.Somanuals.com. All Manuals Search And Download.
6. Check inside the unit for any obvious unsafe conditions, such as metal filings,
contamination, water or other liquids, or signs of fire or smoke damage.
7. Check for worn, frayed, or pinched cables.
8. Check that the power-supply cover fasteners (screws or rivets) have not been
removed or tampered with.
Handling electrostatic discharge-sensitive devices
Any computer part containing transistors or integrated circuits (ICs) should be
considered sensitive to electrostatic discharge (ESD). ESD damage can occur when
there is a difference in charge between objects. Protect against ESD damage by
equalizing the charge so that the machine, the part, the work mat, and the person
handling the part are all at the same charge.
Notes:
1. Use product-specific ESD procedures when they exceed the requirements noted
here.
2. Make sure that the ESD protective devices you use have been certified (ISO 9000)
as fully effective.
When handling ESD-sensitive parts:
•
•
•
•
Keep the parts in protective packages until they are inserted into the product.
Avoid contact with other people.
Wear a grounded wrist strap against your skin to eliminate static on your body.
Prevent the part from touching your clothing. Most clothing is insulative and
retains a charge even when you are wearing a wrist strap.
•
•
Use the black side of a grounded work mat to provide a static-free work surface.
The mat is especially useful when handling ESD-sensitive devices.
Select a grounding system, such as those listed below, to provide protection that
meets the specific service requirement.
Note: The use of a grounding system is desirable but not required to protect
against ESD damage.
— Attach the ESD ground clip to any frame ground, ground braid, or green-wire
ground.
— Use an ESD common ground or reference point when working on a double-
insulated or battery-operated system. You can use coax or connector-outside
shells on these systems.
— Use the round ground-prong of the ac plug on ac-operated computers.
Grounding requirements
Electrical grounding of the computer is required for operator safety and correct
system function. Proper grounding of the electrical outlet can be verified by a
certified electrician.

Problem determination tips
Due to the variety of hardware and software combinations that can be encountered,
use the following information to assist you in problem determination. If possible,
have this information available when requesting assistance from Service Support and
Engineering functions.
•
•
•
Machine type and model
Processor or hard disk upgrades
Failure symptom
— Do diagnostics fail?
— What, when, where, single, or multiple systems?
— Is the failure repeatable?
— Has this configuration ever worked?
— If it has been working, what changes were made prior to it failing?
— Is this the original reported failure?
Reference/ Diagnostics version
— Type and version level
•
•
Hardware configuration
— Print (print screen) configuration currently in use
— BIOS level
•
Operating system software
— Type and version level
Note: To eliminate confusion, identical systems are considered identical only if they:
1. Are the exact machine type and models
2. Have the same BIOS level
3. Have the same adapters/ attachments in the same locations
4. Have the same address jumpers/ terminators/ cabling
5. Have the same software versions and levels
6. Have the same Reference/ Diagnostics Diskette (version)
7. Have the same configuration options set in the system
8. Have the same setup for the operation system control files
Comparing the configuration and software set-up between "working and non-
working" systems will often lead to problem resolution.
