A.20.1 ac_action
Specifies the action the system takes when AC power is applied.
Syntax: set ac_action boot
where value can be:

the default.
standby The system goes to standby when AC power is applied.
A.20.2 auto_action
Specifies the action the console takes any time the system powers up,
fails, or resets. When the setting involves autoboot, the system boots from
the default boot device specified by the value of the bootdef_dev
environment variable.
Syntax: set auto_action value
where value can be:
halt The system remains in console mode after power-up or a system
crash.
boot The system boots automatically when it is turned on and halts after
a system failure.
restart The system boots automatically when it is turned on or after it fails.
NOTE: If a halt assertion exists, the console ignores the auto_action setting and
halts at the SRM console.
