Booting the System Software
Use the boot command to boot the system software. Type boot
[ -ffile] [-n] [arg...] and press Return.
The boot command loads the file that contains the operating
system.
To boot a specific file, replace the optional -f file parameter
with the name of the file you want to use. If you do not
specify -f file, the system loads the file specified by the
bootpath environment variable.
The file parameter has the format
dev([controller][,unit-number] [,partition-number])[filename]
where
dev represents the device from which you are booting
the operating system. Typical devices are rz for a hard
disk, tz for a tape, and mop for a network. Typing mop
nullifies the other arguments in the list, so that file
takes the
controller represents the ID number of the default
controller.
unit-number represents the unit number of the SCSI
or Ethernet device from which you are booting the
operating system.
partition-number represents the number (or other
designator) of the partition from which you are booting
the operating system. When booting from a tape, this
number is not used because the boot file must be the
first thing on the tape. When booting from a disk, this
number depends on how you partitioned the disk when
you installed your operating system software. Refer to
the software installation manual if you need a reminder
about disk partition indicators.
file name represents the name of the operating system
file.
