Operation

3.4.6 Setting Automatic Booting

Tru64 UNIX and OpenVMS operating systems are factory set to halt in the SRM console. You
can change these defaults, if desired.
Compaq ES40CSLP 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)
Setting Tru64 UNIX or OpenVMS Systems to Auto Start
The SRM auto_action environment variable determines the default action the system takes
when the system is power cycled, reset, or experiences a failure. On systems that are factory
configured for Tru64 UNIX or OpenVMS, 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 reboots after an operating
system crash.
To set the default action to boot, enter the following SRM commands:
P00>>> set auto_action boot
P00>>> init
For more information on auto_action, see the Compaq AlphaServer ES40 User Interface
Guide.
