Out-of-band method
See the IMM2 documentation (
Integrated Management Module II User's Guide
) at
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 74. After you have recovered
the firmware in the primary bank, do the following:
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
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
necessary corrections to the configuration and restart the server. If the server is unable to complete POST
with the default configuration successfully, there might be a problem with the system board.
You can set the number of consecutive restart attempts that will trigger the Nx-boot failure feature, in
the Setup Utility. To specify the number, click
