General checkout
The server diagnostic prog rams 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
“Diagnostic programs and error messages” on page 24.
Also, if you cannot determine whether a problem is caused by the hardware or by the
softw a re, you ca n run the diagnostic programs t o confirm that the hard wa re 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 par t of a shared DASD cluster (two or mor e systems s haring
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 sy stems are loca te d 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 mult iple er ror codes are displaye d, diagno se the firs t error code disp laye d.
3. If the computer hangs with a POST error , go to the “Chapter . Symptom-to-FRU
index,” on page 215.
4. If the computer hangs and no error is displayed, go to “Undetermined problems”
on page 241.
5. Power supply problems, see “Chapter . Symptom-to-FRU index,” on page 215.
6. Safety information, see “Safety information” on page 249.
7. For intermittent problems, check the error log; see “PO ST erro r me s s ages” on
page 12.

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
microprocessor s to enhance performance and provide SMP capability.
• Integrated disk-array subsystem
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 an d hot- swa p cap ab ilitie s
All models of the server support up to 10 slim-high or 7 half high hot-swap hard
disk drives . Th is hot-swap feature enables you to remove and replace hard disk
drives without turni ng off the server.
• Hot-plug PCI adapter capabilities
The server ha s f our 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-sta ndard, 3. 3 V, 168-pin, 8-byte, register ed, dual inlin e memory modules
(DIMMs). The memory controller also provides Chipkill™ memory protection.
Chipkill memory protect ion is a technolo gy that protects the syste m from
component fa ilure on a DIMM.
• System-management capabilities
The serve r comes with a Netfinity Advanced System Management Processor.
This processor, in conjunction with the Netfinity Manager software provided on
the ServerGuide CDs, enables you to manage the functions of the server locally
and remotely. The Netfinity Advanced System Management Processor also
provides system monitoring, event recording, and dial-out alert capability.
6 Hardware Maintenance Manual: Netfinity 7600 – Type 8665 Models 1RY, 2RY
Note: The Netfinity Advanced System Management Processor is sometimes
referred to as the service processor.
Refer to “Chapt er . Netfinity Manager,” on page 95 for more 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 sel e cts 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 associ ated with thi s 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 Netfinity 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 pr ogram 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 importan t featu res in server des ign a re 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.
• Menu-driven setup, syste m configu ration, RA ID configurat io n, and diagno s tic
programs
• Power-on self-test (POST)
• Integrated
• Predictive Failure Analysis™ alerts
• Remote system problem-determination support
• Power and temperature monitoring

This section provides basic troubleshooting information to help you resolve some
common pr oblems that might occur wi th the server.
If you cannot locate and correct the problem using the information in this sec tion,
refer to “Chapter . Symptom-to-FRU index,” on page 215 for more informati on .
Diagnostic tools overview
The following tools are available to help you identify and resolve hardware-related
problems:
• POST beep cod es, error m ess ag es, and e rror logs
The power-on self-test (POST) generates beep codes and messages to indicate
successful test completion or the det e ction of a probl e m. See “POST” on page 12
for more information.
• 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. See “Diagn o st ic programs and erro r
messages” on page 24 for more information.
• Light path diagnostics
Your server has light-emitting diodes (LEDs) to help you identify problems with
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
type of system error that occurred. See “Light path diag nostics” on page 27 for
more information.
• Error symptoms
These charts list problem symptoms, along with suggested steps to correct the
problems. See the “Diagnosing errors” on page 34 for more information.
12 Hardware Maintenance Manual: Netfinity 7600 – Type 8665 Models 1RY, 2RY
POST
When you turn on the server, it performs a series of tests to check the operation of
server components an d some of the options installed in th e se rver. This series of te sts
is called the power-on self-test or POST.
If POST finishes without detec ting any pr oblems, a sin gle beep sounds, the f irst sc reen
of the operating system or application progr am 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
on the screen. See “POST beep codes” and “POST error messages” for mo re
information.
Notes:
1.If you have a pow e r-on password or ad ministrato r password set, you must type the
password and press Enter, when prompted, before POST will continue.
2.A single problem might c ause several error messages. When this occurs, work to
correct the cause of the fir st e rror 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 te s t .
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 215.
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, se e “POST error codes” on page 226.
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 sy stem status messages from the Netf inity
Advanced System Managem ent Processor.
To view the contents of the error logs, start the Configuration/Setup Utility program;
then, se l e c t Ev ent/Error Logs from the main menu.
Small computer system interface messages
If you receive a SCSI error message, see “SCSI error codes” on page 236.
Note: If the server does not have a har d disk drive, ig nore 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 cont roller s provide a Device Ev en t Log that collect s statist ics on the
number and types o f events that occur on a selected physical drive. After correct ing a
problem with the array, clear the log so that you can identify any subsequent errors
quickly. For information about clearing the event log, see "eraseevent" on page 170.
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 informa tion to the configu ration 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 atta ched .
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 instal led.
Explanation: When the ServeRAID controller detect s 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 requir ed.

Auto rearran ge.
Explanation: Auto rearrange is enabled or disabled.
Action: This is an information message. No action is requir ed.
Battery-Backup Write Cache Not Responding
Explanation: BIOS co de 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 withou t chang e .
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 wri t e ca ch e .
Diagnostics 15
Configured dri ves are missing.
Explanation: When the ServeRAID controller detects t hat a pr eviously config ured 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: Onli ne 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 ab ove.
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 th is key to acc ept the new state that the Serve RAID
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 c an 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 timel y manner.
Note: A physical drive in the defunct state does not necessarily mean that you need to replace the drive. Before yo u
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. Try rebuilding the drive if you have not already done so. See “Rebuilding a defunct drive” on page 22 for
more information.
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 t he ServeRAID controller detects that a previously configured drive is present, but t he 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 22 for more information.
After you perform these steps, if the physical drive does not function properly, replace the drive. F6 – Cha n ge 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 – Con tinu e star tu p w ith ou t chan gi n g the con f igu rat io n. Press thi s key to
continue without change to the configuration.

Explanation: The server cannot access the ServeRAID controller.
Action: This is a follow-on message t o a preceding message. Follow the Action instructio ns for the preceding message
to resolve the problem.
New controller installed in a configured server or drives are imported.
Explanation: When the ServeRAID controller det ect s t hat 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 prob lem. 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 config ura tion and set th e dri ve to defu nct . Press this key to acc ept th e new
state that the ServeRAID controller will assign to the drive. For example, t he ServeRAID controller will assi gn the drive
a state of de fu n ct or em pty. 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 pro cessor 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.
3. If you have not already attempted to rebuild the drive, try rebuilding it. See “Rebuilding a defunct dri ve” on page
22 for more informa tion.
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 S erveRAID 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:
1. Restart the server and press Ctrl+I to enter the Mini-Configuration program (see “Using the ServeRAID MiniConfiguration program” on page 16 5).
2. Select Advanced Functions.
