Booting and Installing an Operating System 3-3
3.1.1 auto_action
The SRM auto_action environment variable determines the default ac-
tion the system takes when the system is power cycled, reset, or ex-
periences 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 bugcheck (OpenVMS) or panic (Tru64 UNIX or Linux)
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 or the Reset button is pressed.
•
With the restart setting, the operating system boots automatically after the
SRM init command is issued or the Reset button is pressed, and it also re-
boots 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
