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,
refer to the " Solving problems" section in the User’s Reference on the IBM Netfinity
Documentation CD and the "Support for Netfinity Servers" 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 26 for
more information.
•
Troubleshooting chart
This chart lists problem symptoms, along with suggested steps to correct the
problems. See the “Troubleshooting chart” on page 29 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 issued during POST and all system status messages from the
Netfinity 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 upgradable 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 "Solving Problems" section in the User’s Reference on the IBM
Netfinity Documentation CD for more detailed information about the
diagnostic programs.
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.
