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:
  • 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 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:

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 (JP2), or in the case of image corruption, this will occur automatically with the Automated Boot Recovery function.
