11.17.2.4 Booting Standalone BACKUP from a Tape Cartridge (VAX Only)
If the disk containing standalone BACKUP becomes unusable (for example, if
the drive fails), you can boot standalone BACKUP from a tape cartridge. Booting
standalone BACKUP from a tape cartridge takes approximately 20 minutes.
How to Perform This Task
To boot standalone BACKUP from a tape cartridge, use the following procedure:
1. If the operating system is not running, see step 2.
If the operating system is running, log in to the SYSTEM account. Enter the
following command and press Return:
$ @SYS$SYSTEM:SHUTDOWN
Answer the questions. When the procedure asks if an automatic system boot
should be performed, press Return for NO. When the procedure is finished, it
displays the following message:
SYSTEM SHUTDOWN COMPLETE -- USE CONSOLE TO HALT SYSTEM
2. Halt the system.
3. Insert the tape cartridge that contains standalone BACKUP into the tape
cartridge drive.
4. To boot standalone BACKUP, enter the BOOT command followed by the
device name of the tape cartridge drive that contains standalone BACKUP.
For example:
>>> BOOT MUA0
5. Standalone BACKUP displays the following message:
OpenVMS VAX Version V7.3 Major version id = 3 Minor version id = 0
6. The procedure might ask you for the date and time. Enter the date and time
using the 24-hour clock format and press Return. For example:
PLEASE ENTER DATE AND TIME (DD-MMM-YYYY HH:MM) 19-MAY-2000 15:00
7. The procedure displays a list of the local devices on your system and, if you
have them, HSC and MSCP-served devices. For example:
Available device DUA0: device type Generic_DU
Available device MUA0: device type TK50
8. When standalone BACKUP finishes booting, it displays an identification
message followed by the dollar sign prompt ($):
%BACKUP-I-IDENT, standalone BACKUP V7.3; the date is 19-MAY-2000 15:50
$
