Configuration changes, such as added devices or adapter
firmware updates, and firmware or application code problems can cause
the compute node to fail the power-on self-test (POST).
If the compute node fails to POST, it responds in
either of the following ways:
- The compute node restarts automatically and attempts POST again.
- The compute node hangs and you must manually restart the compute
node for the compute node to attempt POST again.
After a specified number of consecutive attempts (automatic or
manual), the Nx boot failure feature causes the compute node 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 compute node. If the compute node 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, complete the following steps:
- Click System Settings.
- Click Recovery.
- Click Post Attempts.
The available options are 3, 6, 9 and Disable.
