Chapter 5. Solving problems
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, see
the "Solving problems" section in the User’s Reference on the IBM xSeries
Documentation CD and the "Server Support" flowchart in the front of this booklet for
additional information.
Diagnostic tools overview
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” and “POST error
messages” on page 32 for more information.
• Troubleshooting chart
This chart lists problem symptoms and suggested steps to correct the problems.
See the “Troubleshooting charts” on page 34 for more information.
• Event or error logs
The system event or error log contains all error messages that are 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.
• Diagnostic programs and error messages
The server diagnostic programs are stored in the read-only memory (ROM) on the
system board. These programs are the primary method of testing the major
components of your server.
Note: See the "Solving Problems" section in the User’s Reference on the IBM
xSeries Documentation CD for more detailed information about the
diagnostic programs.
• Light Path Diagnostics feature
Use the Light Path Diagnostics feature to identify system errors quickly. For more
information about the Light Path Diagnostics feature, see the "Solving Problems"
section in the User’s Reference on the IBM xSeries Documentation CD.
POST beep code descriptions
POST emits one beep to signal successful completion. If POST detects a problem
during startup, other beep codes might occur. You can use the following beep code
descriptions to help identify and resolve problems that are detected during startup.
