3.4.7 Changing the Default Boot Device
Tru64 UNIX or OpenVMS
When you install the Tru64 UNIX or OpenVMS operating system, you designate a default boot
device. You can 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
See the Compaq AlphaServer ES40 User Interface Guide for more information.
3.5 Setting Boot Options for Tru64 UNIX o r OpenVMS
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
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 to enable specific functions during the boot process
ei*0_inet_init or
ew*0_inet_init 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.
ei*0_protocols or
ew*0_protocols Defines a default network boot protocol (bootp or mop).
3.5.1 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.
The syntax is:
set bootdef_dev boot_device
boot_device The name of the device on which the system software has been loaded. To
specify more than one device, separate the names with commas.
