Setting 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.
auto_action
Determines the default action the system takes when the system is
power cycled, reset, or experiences a failure.
bootdef_dev
Device or device list from which booting is to be attempted when
no path is specified on the command line.
boot_file
Specifies a default file name to be used for booting when no file
name is specified by the
boot
command.
boot_osflags
Defines parameters (boot flags) used by the operating system to
determine some aspects of a system bootstrap.
eg*0_inet_init
ei*0_inet_init
ew*0_inet_init
Determines whether the interface's internal Internet database is
initialized from nonvolatile RAM (NVRAM) or from a network
server (through the bootp protocol). Set this environment variable
if you are booting
Tru64 UNIX
from a Remote Installation
Services (RIS) server.
eg*0_protocols
ei*0_protocols
ew*0_protocols
Defines a default network boot protocol (bootp or mop).
