causing the problem. You must remove nonsupported hardware before you contact IBM or an
approved warranty service provider for support.
b. Make sure that the server, operating system, and software are installed and configured
correctly.
Many configuration problems are caused by loose power or signal cables or incorrectly seated
adapters. You might be able to solve the problem by turning off the server, reconnecting
cables, reseating adapters, and turning the server back on. For information about performing
the checkout procedure, see “About the checkout procedure” on page 48. For information
about configuring the server, see Chapter 2 “Configuration information and instructions” on
page 21.
Step 6. See controller and management software documentation.
If the problem is associated with a specific function (for example, if a RAID hard disk drive is
marked offline in the RAID array), see the documentation for the associated controller and
management or controlling software to verify that the controller is correctly configured.
Problem determination information is available for many devices such as RAID and network
adapters.

Step 7. Check for troubleshooting procedures and RETAIN tips.
Troubleshooting procedures and RETAIN tips document known problems and
suggested solutions. To search for troubleshooting procedures and RETAIN tips, go to
http://www.ibm.com/supportportal.
Step 8. Use the troubleshooting tables.
See “Troubleshooting by symptom” on page 59 to find a solution to a problem that has identifiable
symptoms.
A single problem might cause multiple symptoms. Follow the troubleshooting procedure for the
most obvious symptom. If that procedure does not diagnose the problem, use the procedure for
another symptom, if possible.
If the problem remains, contact IBM or an approved warranty service provider for assistance with
additional problem determination and possible hardware replacement. To open an online service
request, go to http://www.ibm.com/support/entry/portal/Open_service_request. Be prepared to
provide information about any error codes and collected data.
Undocumented problems
If you have completed the diagnostic procedure and the problem remains, the problem might not have
been previously identified by IBM. After you have verified that all code is at the latest level, all hardware
and software configurations are valid, and no light path diagnostics LEDs or log entries indicate a hardware
component failure, contact IBM or an approved warranty service provider for assistance.
To open an online service request, go to http://www.ibm.com/support/entry/portal/Open_service_request.
Be prepared to provide information about any error codes and collected data and the problem determination
procedures that you have used.
