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:
- In-band method: Recover server firmware, using either the
boot block jumper (Automated Boot Recovery) and a server Firmware
Update Package Service Pack.
- Out-of-band method: Use the IMM2.1 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:
- Download the server firmware update from the World Wide Web.
- Contact your Lenovo service representative.
To download the server firmware update package from
the World Wide Web, go to the Lenovo Support Portal.
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 boot the backup bank with the UEFI boot backup jumper (JP16),
or in the case of image corruption, this will occur automatically
with the Automated Boot Recovery function.
