for support.
In-band automated boot recovery method
Note: Use this method if the 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.
1. Boot the server to an operating system that is supported by the firmware update
package that you downloaded.
2. Perform the firmware update by following the instructions that are in the
firmware update package readme file.
3. Restart the server.
4. At the firmware splash screen, press F3 when prompted to restore to the
primary bank. The server boots from the primary bank.
Automated boot recovery (ABR)
While the server is starting, if the integrated management module 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 253. After you have recovered the
firmware in the primary bank, complete the following steps:
1. Restart the server.
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:
v
The server restarts automatically and attempts POST again.
v 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
Settings > POST Attempt Limit . The
available options are 3, 6, 9, and 255 (disable Nx boot failure).
