Operation 3-19

The bootdef_dev environment variable specifies the default boot device. In

this example, the default boot device was previously set to dua1.8.0.4.1. See

Section 4.18 for commands used with environment variables.

The show device command displays device information, including name and

type of connection to the system. See Section 4.3 for a description of the show

device command and the device naming convention.

The disk dua1.8.0.4.1 is on the CI cluster that includes this system.

No boot device is specified in the boot command; the default boot device was

set with the environment variable. See Section 4.5 for a description of the boot

command.

The boot command accepts the name of a boot device, a boot file name

through the -file option, and boot flags through the -flags option. The

environment variables bootdef_dev, boot_file, and boot_osflags can also be

used to specify the default boot device or device list, the default boot file, and

flag information. When an option and the corresponding environment variable

are both in a command string, the option overrides the environment variable.

The value of the environment variable, however, is not changed. See Section

4.18 for information about environment variables.

The operating system banner prints.
