Changing the Default Boot Device | Compaq GS320, GS160, GS80

7.4.1Setting 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

7.5Changing the Default Boot Device

You can change the default boot device for Tru64 UNIX or OpenVMS with the set bootdef_dev command.

With the Tru64 UNIX or OpenVMS operating systems, you can designate a default boot device. You change the default boot device by using the set bootdef_dev SRM console command. For example, to set the boot device to the IDE CD-ROM, enter commands similar to the following:

P00>>> show bootdef_dev bootdef_dev dka400.4.0.1.1

P00>>> set bootdef_dev dqa500.5.0.1.1 P00>>> show bootdef_dev bootdef_dev dqa500.5.0.1.1
