infocenter/toolsctr/v1r0/index.jsp and click UpdateXpress System Pack
Installer.
Be sure to separately install any listed critical updates that have release
dates that are later than the release date of the UpdateXpress System
Pack or UpdateXpress image.
When you click an update, an information page is displayed, including a
list of the problems that the update fixes. Review this list for your
specific problem; however, even if your problem is not listed, installing
the update might solve the problem.
b. Check for and correct an incorrect configuration.
If the server is incorrectly configured, a system function can fail to work
when you enable it; if you make an incorrect change to the server
configuration, a system function that has been enabled can stop working.
1) Make sure that all installed hardware and software are supported.
See http://www.ibm.com/servers/eserver/serverproven/compat/us/ to
verify that the server supports the installed operating system, optional
devices, and software levels. If any hardware or software component is
not supported, uninstall it to determine whether it is causing the problem.
You must remove nonsupported hardware before you contact IBM or an
approved warranty service provider for support.
2) 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 "Checkout procedure" on page
73.
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 adapter and management or
controlling software to verify that the adapter is correctly configured.
Problem determination information is available for many devices such as
RAID and network adapters.
For problems with operating systems or IBM software or devices,
complete the following steps.
