Chapter 3. Diagnostics
This chapter provides basic troubleshooting information to help you solve some
common problems that might occur with the server.
If you cannot locate and correct the problem using the information in this chapter,
see Appendix A, “Getting help and technical assistance,” on page 99 for more
information.

The diagnostic programs are 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), serial ports, hard disk drives, and parallel port. You can also use
them to test some external devices. See “Diagnostic programs and error messages”
on page 16..
Also, if you cannot determine whether a problem is caused by the hardware or by
the software, you can run the diagnostic programs to confirm that the hardware is
working correctly.
When you run the diagnostic programs, a single 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.
A failed server might be part of a shared hard disk drive cluster (two or more
servers sharing the same external storage devices). Before running the diagnostic
programs, make sure that the failing server is not part of a shared hard disk drive
cluster.
A server might be part of a cluster if one or more of the following is true:
v
The customer identifies the server as part of a cluster.
v One or more external storage units are attached to the server and at least one of
the attached storage units is additionally attached to another server or
unidentifiable source.
v
One or more servers are located near the failing server.
If the failing server is suspected to be part of a shared hard disk drive cluster, all
diagnostic tests can be run except diagnostic tests that test the storage unit (a hard
disk drive in the storage unit) or the storage adapter that is attached to the storage
unit.
Notes:
1. For servers that are part of a shared hard disk drive cluster, run one test at a
time in looped mode. Do not run all tests in looped mode, because this could
enable the hard disk drive diagnostic tests.
2. If multiple error codes are displayed, diagnose the first error code that is
displayed.
3. If the server is suspended with a POST error, go to “POST error codes” on
page 84.
