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.
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:
•
In-band method:
Recover the server firmware, using either the SW1 switch block (Automated Boot
Recovery) and a server Firmware Update Package Service Pack.
•
Out-of-band method:
Use the IMM web interface to update the firmware, using the latest server firmware
update package.
Notes:
You can obtain a server update package from one of the following sources:
• Download the server firmware update from the World Wide Web.
• Contact your 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
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 130 for more information), 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:
Step 1. Turn off the server, and disconnect all power cords and external cables.
Step 2. Locate the SW1 switch block on the standard I/O book.
