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.
For more information about UEFI-compliant firmware, go to
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" on page 156. After you have recovered the firmware in the
primary bank, complete the following steps:
Step 1.
Restart the server.
When the prompt press F3 to restore to primary is displayed, press F3 to recover the primary bank.
Step 2.
Pressing F3 will restart the server.
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
necessary corrections to the configuration and restart the server. If the server is unable to successfully
complete POST with the default configuration, there might be a problem with the system board.
To specify the number of consecutive restart attempts that will trigger the Nx-boot failure feature, in the
Setup utility, click System Settings ➙ Recovery ➙ POST Attempts ➙ POST Attempts Limit. The available
options are 3, 6, 9, and 255 (disable Nx-boot failure).
