6.2Setting Boot Options

You can set a default boot device, boot flags, and network boot protocols for Tru64 UNIX or OpenVMS using the SRM set command with environment variables. Once these environment variables are set, the boot command defaults to the stored values. You can override the stored values for the current boot session by entering parameters on the boot command line.

The SRM boot-related environment variables are listed below and described in the following sections:

bootdef_dev

boot_file

boot_osflags

ei*0_inet_init or ew*0_inet_init

ei*0_protocols or ew*0_protocols

Defines a default boot device.

Specifies a default file name to be used for booting when no file name is specified by the boot command.

Defines parameters to enable specific functions during the boot process.

Determines whether the interface’s internal Internet database is initialized from nvram or from a network server (through the bootp protocol). Set this environment variable if you are booting Tru64 UNIX from a RIS server.

Defines a default network boot protocol (bootp or mop).

6.2.1Bootdef_dev

The bootdef_dev environment variable specifies one or more devices from which to boot the operating system. When more than one device is specified, the system searches in the order listed and boots from the first device.

Enter the show bootdef_dev command to display the current default boot device. Enter the show device command for a list of all devices in the system.
