IBM x3250 M3 Problem Determination And Service Manual page 21

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. See "Checkout procedure" on
page 54 for the instructions to perform the checkout procedures.
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.
For problems with operating systems or IBM software or devices,
complete the following steps.
Note: Changes are made periodically to the IBM website. The actual
procedure might vary slightly from what is described in this document.

b) Under Product support, click System x.
c) From the Product family list, select System x3250 M3.
d) Under Support & downloads, click Documentation, Install, and
Use to search for related documentation.
c. Check for service bulletins.
IBM service bulletins document known problems and suggested solutions.
To search for service bulletins, complete the following steps.
Note: Changes are made periodically to the IBM website. The actual
procedure might vary slightly from what is described in this document.
1) Go to http://www.ibm.com/systems/support/.
2) Under Product support, click System x.
3) From the Product family list, select System x3250 M3.
4) Under Support & downloads, click Troubleshoot.
d. Check for and replace defective hardware.
If a hardware component is not operating within specifications, it can cause
unpredictable results. Most hardware failures are reported as error codes in
a system or operating-system log. See "Troubleshooting tables" on page 57
and Chapter 5, "Removing and replacing server components," on page 127
for more information. Hardware errors are also indicated by LEDs on the
system board (see "System-board LEDs" on page 18 for more information).
