Diagnostic Programs, Messages, And Error Codes; Running The Diagnostic Programs - IBM xSeries 100 Problem Determination And Service Manual

Diagnostic programs, messages, and error codes

The server diagnostic programs are the primary method of testing the major
components of the server. As you run the diagnostic programs, text messages and
error codes are displayed on the screen and are saved in the test log. A diagnostic
text message or error code indicates that a problem has been detected; to
determine what action you should take as a result of a message or error code, see
the table in "Diagnostic error codes" on page 39.

Running the diagnostic programs

To run the diagnostic programs, complete the following steps:
10. From the diagnostic programs screen, select the test that you want to run, and
To determine what action you should take as a result of a diagnostic text message
or error code, see the table in "Diagnostic error codes" on page 39.
If the diagnostic programs do not detect any hardware errors but the problem
remains during normal server operations, a software error might be the cause. If
you suspect a software problem, see the information that comes with your software.
A single problem might cause more than one error message. When this happens,
correct the cause of the first error message. The other error messages usually will
not occur the next time you run the diagnostic programs.
Exception: If there are multiple error codes that indicate a microprocessor error,
the error might be in a microprocessor or in a microprocessor socket. See
"Microprocessor problems" on page 30 for information about diagnosing
microprocessor problems.
If the server stops during testing and you cannot continue, restart the server and try
running the diagnostic programs again. If the problem remains, replace the
component that was being tested when the server stopped.
1. If the server is running, turn off the server and all attached devices.
2. Turn on all attached devices; then, turn on the server.
3. When you see Press <F1> for Configuration/Setup, press F1.
4. When the Configuration/Setup Utility menu appears, select Startup Option →
Startup Sequence Options.
5. Note the device that is selected as the first startup device. Later, you must
restore this setting.
6. Make sure that CD/DVD-ROM is selected as the first startup device.
7. Press Esc two times to return to the Configuration/Setup Utility menu.
8. Insert the IBM Enhanced Diagnostics CD in the CD or DVD drive.
9. Select Save Settings; then, select Exit Setup and follow the prompts. The
diagnostic programs will load.
follow the instructions on the screen.
When you are diagnosing hard disk drives, select SCSI Fixed Disk Test for
the most thorough test. Select Fixed Disk Test for any of the following
situations:
v You want to run a faster test.
v The server contains RAID arrays.
v The server contains SATA or IDE hard disk drives.
