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 Defines a default boot device.
Specifies a default file name to be used for booting when no file
boot_file
name is specified by the boot command.
Defines parameters to enable specific functions during the boot
boot_osflags
process.
Determines whether the interface's internal Internet database is
ei*0_inet_init or
initialized from nvram or from a network server (through the bootp
ew*0_inet_init
protocol). Set this environment variable if you are booting UNIX from
a RIS server.
Defines a default network boot protocol (bootp or mop).
ei*0_protocols or
ew*0_protocols
bootdef_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.
