Recovering the server firmware

Use this information to recover the server firmware.

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:
  • 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 IMM Web Interface to update the firmware, using the latest server firmware update package.
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 IBM service representative.

To download the server firmware update package from the World Wide Web, go to Lenovo Data Center Support.

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.
