Recovering the server firmware (UEFI update failure)
Use this information to recover the server firmware.
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 the following way:
v In-band method: Recover server firmware, using either the boot block jumper
(Automated Boot Recovery) and a server Firmware Update Package Service
Pack.
v Out-of-band method: Use the IMM web interface to update the firmware, using
the latest server firmware update package.
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/.
The flash memory of the server consists of a primary bank and a back up bank.
You must maintain a bootable UEFI firmware image in the back up bank. If the
server firmware in the primary bank becomes corrupted, you can either manually
boot the back up bank with the UEFI boot backup jumper (J15), or in the case of
image corruption, this will occur automatically with the Automated Boot Recovery
function.
In-band manual recovery method
This section details the in-band manual recovery method.
About this task
To recover the server firmware and restore the server operation to the primary
bank, complete the following steps:
Procedure
1. Read the safety information that begins on “Safety” on page vii and
“Installation guidelines” on page 283.
2. Turn off the server, and disconnect all power cords and external cables.
3. Remove the cover (see “Removing the top cover” on page 146).
4. Locate the UEFI boot backup jumper (J15) on the system board.
