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.
About this task
For instructions for recovering the UEFI firmware, see "Recovering the server
firmware (UEFI update failure)" on page 179. After you have recovered the
firmware in the primary bank, complete the following steps:
Procedure

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:
v The server restarts automatically and attempts POST again.
v The server hangs, and you must manually restart the server for the server to
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).
