3.2.1.1 auto_action
The SRM auto_action environment variable determines the default
action the system takes when the system is power cycled, reset, or
experiences a failure.
Systems can boot automatically (if set to autoboot) from the default boot device
under the following conditions:
• When you first turn on system power
• When you power cycle or reset the system
• When system power comes on after a power failure
• After a panic
The factory setting for auto_action is halt. The halt setting causes the system
to stop in the SRM console. You must then boot the operating system manually.
For maximum system availability, auto_action can be set to boot or restart.
• With the boot setting, the operating system boots automatically after the
SRM init command is issued.
• With the restart setting, the operating system boots automatically after the
SRM init command is issued, and it also reboots after an operating system
crash.
Example
To set the default action to boot, enter the following SRM commands:
P00>>> set auto_action boot
P00>>> init
