Recovering From A Uefi Update Failure Or Uefi Image Corruption - IBM x3690 X5 Service Manual

Recovering from a UEFI update failure or UEFI image corruption

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 server firmware, using either the boot block jumper
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

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 IBM System x Server Firmware (server firmware) image
in the backup bank. If the server firmware in the primary bank becomes corrupted,
you can either manually boot the backup bank with the boot block jumper, or in
the case of image corruption, this will occur automatically with the Automated
Boot Recovery function.
In-band manual recovery method
To recover the server firmware and restore the server operation to the primary
bank, complete the following steps:
