Updating the firmware
This topic provides information about updating the server firmware.
Important: Before upgrading server firmware, backup the system configuration of the server to a file using
the ASU save
<filename>
command,
where
<filename>
is the complete path name of the file where the configuration is to be saved. See the ASU
User’s Guide , available from the https://support.lenovo.com/solutions/LNVO-ASU , for information and
instructions.
Notes:
• 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.
• Before you update the firmware, be sure to back up any data that is stored in the Trusted Platform Module
(TPM), in case any of the TPM characteristics are changed by the new firmware. For instructions, see your
encryption software documentation.
To check for the latest level of firmware, such as the UEFI firmware, vital product data (VPD), device drivers,
and integrated management module (IMM) firmware, go to
http://datacentersupport.lenovo.com/
.
Attention: 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.
You can install code updates that are packaged as an Update Xpress System Pack or Update Xpress CD
image. An Update Xpress System Pack contains an integration-tested bundle of online firmware and device-
driver updates for your server. Use Update Xpress System Pack Installer to acquire and apply Update Xpress
System Packs and individual firmware and device-driver updates. For additional information and to
download the Update
Xpress System Pack Installer, go to the ToolsCenter for Lenovo x86 servers at https://
datacentersupport.lenovo.com/us/en/ documents/LNVO-CENTER and click UpdateXpress System Pack
Installer .
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.
Be sure to separately install any listed critical updates that have release dates that are later than the release
date of the Update
Xpress System Pack or Update Xpress image.
The firmware for the server is periodically updated. Download the latest firmware for the server; then, install
the firmware, using the instructions that are included with the downloaded files.
When you replace a device in the server, you might have to update the firmware that is stored in memory on
the device or restore the pre-existing firmware from a CD or DVD image.
