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 130.
For information about configuring the server, see Chapter 3, “Configuring,”
on page 101.
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.

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/.
8. Use the troubleshooting tables. See “Troubleshooting by symptom” on page
153 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.
