vi xSeries 200 Type 8479 and xSeries 200VL Type 8481: Hardware Maintenance Manual

General checkout
The server diagnostic programs are stored on the IBM Enhanced Diagnostics CD.
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 10.
Also, if you cannot determine whether aproblem 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, asingle 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.
Afailed system might be part of ashared 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 ashared DASD cluster.
Asystem might be part of acluster if:
vThe customer identifies the system as part of acluster.
vOne 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.
vOne or more systems are located near the failing system.
If the failing system is suspected to be part of ashared 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 ashared DASD cluster, run one test at atime 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.
3. If the computer hangs with aPOST error, go to the “Symptom-to-FRU index”
on page 89.
4. If the computer hangs and no error is displayed, go to “Undetermined
problems” on page 97.
5. Power supply problems, see “Symptom-to-FRU index” on page 89.
6. Safety information, see “Safety information” on page 103.
7. For intermittent problems, check the error log; see “POST error messages” on
page 9.
©Copyright IBM Corp. 2001 1

1. IS THE SYSTEM PART OF ACLUSTER?
YES. Schedule maintenance with the customer. Shut down all systems related to
the cluster. Run storage test.
NO. Go to step 2.
2. IF THE SYSTEM IS NOT PART OF ACLUSTER:
vPower-off the computer and all external devices.
vCheck all cables and power cords.
vSet all display controls to the middle position.
vPower-on all external devices.
vPower-on the computer.
vRecord any POST error messages displayed on the screen. If an error is
displayed, look up the first error in the “POST error messages” on page 95.
vCheck the System Error Log. If an error was recorded by the system, see
“Symptom-to-FRU index” on page 89.
vStart the Diagnostic Programs. See “Diagnostic programs and error
messages” on page 10.
vCheck for the following responses:
a. One beep.
b. Readable instructions or the Main Menu.
3. DID YOU RECEIVE BOTH OF THE CORRECT RESPONSES?
NO. Find the failure symptom in “Symptom-to-FRU index” on page 89.
YES. Run the Diagnostic Programs. If necessary, refer to “Diagnostic programs and
error messages” on page 10.
If you receive an error, go to “Symptom-to-FRU index” on page 89.
If the diagnostics completed successfully and you still suspect aproblem, see
“Undetermined problems” on page 97.

8xSeries 200 Type 8479 and xSeries 200VL Type 8481: Hardware Maintenance Manual

Diagnostics
This section provides basic troubleshooting information to help you resolve some
common problems that might occur with the server.
If you cannot locate and correct the problem using the information in this section,
refer to “Symptom-to-FRU index” on page 89 for more information.
Diagnostic tools overview
The following tools are available to help you identify and resolve hardware-related
problems:
vPOST beep codes
The power-on self-test (POST) generates beep codes and messages to indicate
successful test completion or the detection of aproblem. See “POST” for more
information.
vDiagnostic programs and error messages
The server diagnostic programs are provided on the IBM Enhanced Diagnostics
CD. These programs test the major components of the server. See “Diagnostic
programs and error messages” on page 10 for more information.
POST
When you turn on the server, it performs aseries 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, the first window of the operating
system or application program appears.
Note:
1. If you have apower-on password or administrator password set, you
must type the password and press Enter, when prompted, before POST
will continue.
2. Asingle 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 code descriptions
POST generates beep codes to indicate successful completion or the detection of a
problem.
vOne short beep indicates the successful completion of POST.
vMore than one beep indicates that POST detected aproblem. For more
information, see “Beep symptoms” on page 89“.
POST error messages
The possible types of beep codes that your system might emit are:
©Copyright IBM Corp. 2001 9

Repeating long beeps
Indicates that amemory error has occurred. Ensure that all DIMMs are
correctly installed.
One long beep and two short beeps
Indicates that avideo error has occurred and the BIOS cannot initialize the
video screen to display any additional information. Ensure that the video
adapter is correctly installed.
For alist of POST errors, see “POST error messages” on page 95.
Small computer system interface messages (some models)
The following table lists actions to take if you receive aSCSI error message.
Note: If the server does not have aSCSI hard disk drive, ignore any message that
indicates that the BIOS is not installed.
You will get these messages only when running the SCSI Select Utility.
Table 2. SCSI messages
SCSI Messages Description
All One or more of the following might be causing the problem.
vAfailing SCSI device (adapter or drive)
vAn improper SCSI configuration
vDuplicate SCSI IDs in the same SCSI chain
vAn improperly installed SCSI terminator
vAdefective SCSI terminator
vAn improperly installed cable
vAdefective cable
Action: Verify that:
vThe external SCSI devices are turned on. External SCSI devices must
be turned on before the server.
vThe cables for all external SCSI devices are connected correctly.
vThe last device in each SCSI chain is terminated properly.
vThe SCSI devices are configured correctly.
If the above items are correct, run the diagnostic programs to obtain
additional information about the failing device.
Diagnostic programs and error messages
The server diagnostic programs are stored on the IBM Enhanced Diagnostics CD.
These programs provide the primary methods of testing the major components of
the server.
Diagnostic error messages indicate that aproblem exists; they are not intended to
be used to identify afailing part. Troubleshooting and servicing of complex
problems that are indicated by error messages should be performed by trained
service personnel.
10 xSeries 200 Type 8479 and xSeries 200VL Type 8481: Hardware Maintenance Manual

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.
The error code format is as follows:
fff-ttt-iii-date-cc-text message
where:
fff is the three-digit function code that indicates the function being
tested when the error occurred. For example, function code 089 is
for the microprocessor.
ttt is the three-digit failure code that indicates the exact test failure
that was encountered.
iii is the three-digit device ID.
date is the date that the diagnostic test was run and the error recorded.
cc is the check digit that is used to verify the validity of the
information.
text message is the diagnostic message that indicates the reason for the problem.
Text messages
The diagnostic text message format is as follows:
Function Name: Result (test specific string)
where:
Function Name
is the name of the function being tested when the error occurred. This
corresponds to the function code (fff) given in the previous list.
Result can be one of the following:
Passed
This result occurs when the diagnostic test completes without any
errors.
Failed This result occurs when the diagnostic test discovers an error.
User Aborted
This result occurs when you stop the diagnostic test before it is
complete.
Not Applicable
This result occurs when you specify adiagnostic test for adevice
that is not present.
Aborted
This result occurs when the test could not proceed because of the
server configuration.
Warning
This result occurs when apossible problem is reported during the
diagnostic test, such as when adevice that is to be tested is not
installed.
Diagnostics 11

Test Specific String
This is additional information that is used to analyze the problem.
Starting the diagnostic programs
The IBM Enhanced Diagnostics programs will isolate the server hardware from
software that you have installed on your hard disk drive. The programs run
independently of the operating system, and must be run either from the CD or from
the diskette.This method of testing is generally used when other methods are not
accessible or have not been successful in isolating aproblem suspected to be
hardware related.
An IBM Enhanced Diagnostics CD comes with the server. You can also download
the latest image of the diagnostics from the World Wide Web at
