Recovering The Server Firmware - IBM 7378 Problem Determination And Service Manual

Recovering 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 one 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,
complete the following steps.
Note: Changes are made periodically to the IBM Web site. The actual procedure

The flash memory of the server consists of a primary bank and a backup bank. It is
essential that you maintain the backup bank with a bootable firmware image. If 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.

To recover the server firmware and restore the server operation to the primary
bank, complete the following steps:
