Recovering from a UEFI update failure or UEFI image corruption

This topic provides instructions on how to recover from a UEFI update failure or
UEFI image corruption.
About this task
Important: 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.
If the server firmware has become corrupted, such as from a power failure during
an update, you can recover the server firmware in either of two ways:
v In-band method: Recover the server firmware, using either the SW1 switch
v Out-of-band method: Use the IMM web interface to update the firmware, using
Note: You can obtain a server update package from one of the following sources:
v Download the server firmware update from the World Wide Web.
v Contact your IBM service representative.
To download the server firmware update package from the World Wide Web, go to
http://www.ibm.com/supportportal/.
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.
The flash memory of the server consists of a primary bank and a backup bank. You
must maintain a bootable UEFI firmware image in the backup bank. If the server
firmware in the primary bank becomes corrupted, you can either manually change
the position of switch 7 on the SW1 switch block to ON (see "Starting the backup
server firmware" on page 134 for more information), or in the case of image
corruption, this will occur automatically with the Automated Boot Recovery
function.
