In-band automatic recovery method
This topic provides information about the in-band automatic recovery method, as
well as instructions for how to recover the UEFI firmware and restore the server
operation to the primary bank.
If the integrated management module (IMM) detects a problem with the UEFI
firmware in the primary bank, the automatic boot recovery function starts the
server from the backup bank so that you can restore the UEFI firmware in the
primary bank. Use this method if the BRD LED on the light path diagnostics panel
is lit and there is an event log entry or if Booting Backup Image is displayed on the
firmware splash screen; otherwise, use the in-band manual recovery method.
To recover the UEFI firmware and restore the server operation to the primary
bank, complete the following steps:
1. Boot the server to an operating system that is supported by the IBM Flash UEFI
Update package that you downloaded.
2. Install the IBM Flash UEFI Update package, following the instructions in the
readme file that comes with the update package.
3. Restart the server.
4. When the prompt Press F3 to restore to primary is displayed, press F3 to
start the server from the primary bank.
In-band manual recovery method
This topic provides steps to recover the UEFI firmware and restore the server
operation to the primary bank.
To recover the UEFI firmware and restore the server operation to the primary
bank, complete the following steps:
1. Turn off the server, and disconnect all power cords and external cables.
2. Remove the server top cover. See “Removing and replacing consumable parts
and Tier 1 CRUs” on page 105 for more information.
3. Locate the boot recovery jumper (J22) on the I/O board.
4. Move the jumper from pins 1 and 2 to pins 2 and 3 to enable the UEFI
firmware recovery mode.
5. Reinstall the server cover; then, reconnect all power cords.
6. Restart the server. The power-on self-test (POST) starts.
7. Boot the server to an operating system that is supported by the firmware
update package that you downloaded.
8. Perform the firmware update by following the instructions that are in the
firmware update package readme file.
9. Copy the downloaded firmware update package into a directory.
10. From a command line, type filename-s, where filename is the name of the
executable file that you downloaded with the firmware update package.
11. Turn off the server and disconnect all power cords and external cables, and
then remove the server cover.
12. Move the boot recovery jumper back to the primary position (pins 1 and 2).
13. Reinstall the server cover, and then reconnect all the power cables.
14. Restart the server.
