Timed power-on - refer to the shutdown -t command on servers using AIX.
Working in conjunction with AIX, the Service Processor in your server can
operate a timer, much like the wake-up timer on your clock radio. You can set
the timer so that your server powers on at a certain time after shutting down.
The timer is battery-operated, so power interruptions that occur while the server
is off do not affect its accuracy. Refer to the AIX shutdown -t command for
details on setting the timer.
Note: If an ac power loss is in progress when the Timed Power-On attempt
occurs, the server is not able to power on when ac power is restored.
Follow-up to a Failed Boot Attempt
The service processor initiates a power-on sequence if a failed boot attempt is
detected (due to a hardware or software failure).
Fast/Slow Boot (IPL) Capabilities
Using the service processor menus, you can select the IPL type, mode, and
speed of your boot capabilities.
Attention: Selecting fast IPL results in several diagnostic tests being skipped
and a shorter memory test being run.
