Step 21. Restart the server. The system begins the power-on self-test (POST).
Step 22. If these recovery efforts fail, contact your IBM service representative for support.
In-band automated boot recovery method
This section details the in-band automated boot recovery method.
Note:
Use this method if the System board LED on the light path diagnostics panel is lit and there is a log
entry or
Booting Backup Image
is displayed on the firmware splash screen; otherwise, use the in-band
manual recovery method.
Step 1.
Boot the server to an operating system that is supported by the firmware update package that
you downloaded.
Step 2.
Perform the firmware update by following the instructions that are in the firmware update package
readme file.
Step 3.
Restart the server.
Step 4.
At the firmware splash screen, press F3 when prompted to restore to the primary bank. The
server boots from the primary bank.
Out-of-band method
See the IMM2 documentation (
Integrated Management Module II User's Guide
) at
Automated boot recovery (ABR)
Use this information for Automated boot recovery (ABR).
While the server is starting, if the integrated management module II detects problems with the server
firmware in the primary bank, the server automatically switches to the backup firmware bank and gives
you the opportunity to recover the firmware in the primary bank. For instructions for recovering the UEFI
firmware, see “Recovering the server firmware (UEFI update failure)” on page 118. After you have recovered
the firmware in the primary bank, complete the following steps:
Step 1.
Restart the server.
Step 2.
When the prompt
Press F3 to restore to primary
is displayed, press
F3
to start the server from
the primary bank.
Nx-boot failure
Use this information for Nx-boot failure.
Configuration changes, such as added devices or adapter firmware updates, and firmware or application
code problems can cause the server to fail POST (the power-on self-test). If this occurs, the server responds
in either of the following ways:
• The server restarts automatically and attempts POST again.
• The server hangs, and you must manually restart the server for the server to attempt POST again.
After a specified number of consecutive attempts (automatic or manual), the Nx-boot failure feature causes
the server to revert to the default UEFI configuration and start the Setup utility so that you can make the
