To boot from a drive, the file specification form is
slot/(rz | tz)drive/ file.
When you type this file specification, use the (rz | tz)
parameter to specify the type of drive that performs the
boot operation. Specify rz to boot from a hard disk or
compact disc drive. Specify tz to boot from a tape drive.
Replace slot with the SCSI controller slot number.
Replace drive with the drive SCSI ID for the drive you
are using to boot.
Replace file with the name of the specific file you want
to boot.
For example, to boot the file named vmunix from a
hard disk drive with SCSI ID 1 that is on the SCSI bus
connected to the base system SCSI controller in slot 5,
type 5/rz1/vmunix and press Return.
To boot the file called vmunix from a tape drive, with
SCSI ID 2 that is on the SCSI bus connected to a SCSI
controller in option slot 1, type 1/tz2/vmunix and press
Return.
To perform a multiuser boot, include the -a parameter. If
you omit the -a parameter, the system performs a single-
user boot.
Important information about typing the boot command
If you include no arguments in the boot command, the
system uses the boot environment variable as the argument
string for the boot command.
If you include any additional arguments, you must type the
entire argument string in the boot command. The system
ignores the boot environment variable whenever you specify
any additional arguments in the boot command.
If you use any spaces or tabs in the boot environment
variable, you must surround the entire variable with double
quotes. For example, to set the boot environment variable
to use the protocol mop to perform a multiuser boot from
the Ethernet in slot 6, type "6/mop -a".
