Step 4. Check for and apply code updates.Fixes or workarounds for many problems might be available
in updated UEFI firmware, device firmware, or device drivers. To display a list of available updates
for the server, go to http://www.ibm.com/support/ fixcentral.
Installing the wrong firmware or device-driver update might cause the server to malfunction. Before
you install a firmware or device-driver update, read any readme and change history files that are
provided with the downloaded update. These files contain important information about the update
and the procedure for installing the update, including any special procedure for updating from an
early firmware or device-driver version to the latest version.
Some cluster solutions require specific code levels or coordinated code updates. If the device is
part of a cluster solution, verify that the latest level of code is supported for the cluster solution
before you update the code.
a. Install UpdateXpress system updates.You can install code updates that are packaged as
an UpdateXpress System Pack or UpdateXpress CD image. An UpdateXpress System Pack
contains an integration-tested bundle of online firmware and device-driver updates for your
server. In addition, you can use the ToolsCenter Bootable Media Creator to create bootable
media that is suitable for applying firmware updates and running preboot diagnostics. For
more information about UpdateXpress System Packs, see http://www.ibm.com/support/entry/
portal/docdisplay?lndocid=SERV-XPRESSand "Updating the firmware" on page 131. For
more information about the Bootable Media Creator, see https://support.lenovo.com/
us/en/documents/LNVO-BOMC.
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 (see Install
manual system updates).
b. Install manual system updates.
1. Determine the existing code levels.
In DSA, click Firmware/VPD to view system firmware levels, or click Software to view
operating-system levels.
2. Download and install updates of code that is not at the latest level.
To display a list of available updates for the server, go to http://www.ibm.com/support/
fixcentral.
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.
Step 5. 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.
a. Make sure that all installed hardware and software are supported.See
http://www.lenovo.com/ serverproven/ 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 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 159.
For information about configuring the server, see "Configuring the server" on page 132.
