Chapter 5. Solving problems

Diagnostic tools overview

© Copyright IBM Corp. 2000
This section provides basic troubleshooting information to help you resolve some
common problems that might occur while setting up your server.
If you cannot locate and correct the problem using the information in this section,
refer to the User's Reference on the IBM xSeries Documentation CD and the "Server
Support" flowchart in the front of this booklet for additional information.
The following tools are available to help you identify and resolve hardware-related
problems:
•
Beep codes and error messages
The power-on self-test (POST) generates beep codes to indicate successful test
completion or the detection of a problem.
— One beep indicates successful completion of POST.
— More than one beep indicates that POST detected a problem. Error messages
also appear during startup if POST detects a hardware-configuration
problem.
See "POST beep code descriptions" on page 42 and "POST error messages" on
page 43 for more information.
• Troubleshooting chart
This chart lists problem symptoms and suggested steps to correct the problems.
See the "Troubleshooting chart" on page 45 for more information.
• 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 that are issued during POST and all system status messages from
the system-management adapter.
To view the contents of the error logs, start the Configuration/Setup Utility
program; then, select Event/Error Logs from the main menu.
• Diagnostic programs and error messages
The server diagnostic programs are stored in upgradeable read-only memory
(ROM) on the system board. These programs are the primary method of testing
the major components of your server.
Note: Refer to the User's Reference on the IBM xSeries Documentation CD for
more detailed information about the diagnostic programs.
