3.1.3 boot_osflags

The boot_osflags environment variable sets the default boot flags and,

for OpenVMS, a root number.

Boot flags contain information used by the operating system to determine some

aspects of a system bootstrap. Under normal circumstances, you can use the

default boot flag settings.

To change the boot flags for the current boot only, use the flags_value argument

with the boot command.

The syntax is:

set boot_osflags flags_value

The flags_value argument is specific to the operating system.

UNIX Systems

UNIX systems take a single ASCII character as the flags_value argument.

Load operating system software from the specified boot device

(autoboot). Boot to multiuser mode.

Prompt for the name of a file to load and other options (boot

interactively). Boot to single-user mode.

Stop in single-user mode. Boots /vmunix to single-user mode and stops

at the # (root) prompt.

D Full dump; implies “s” as well. By default, if UNIX crashes, it

completes a partial memory dump. Specifying “D” forces a full dump at

system crash.
