3.1 Setting Boot Options
You can set a default boot device, boot flags, and network boot proto-
cols by 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. For more
information on setting boot options, see Chapter 5.
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 sys-
tem to determine some aspects of a system bootstrap.
ei*0_inet_init or
ew*0_inet_init
Determines whether the interface's internal Internet da-
tabase is initialized from nvram or from a network server
(through the bootp protocol). Set this environment vari-
