Backing Up In Volume Mode; Example - HP BACKCOPY Reference Manual

more information on creating DEFINEs, see
on CLASS TAPE CATALOG, see the DSM/Tape Catalog User's Guide.
To use the DEFINE =MYBACKUP to specify using two scratch tape volumes, NY082 and
NY004, as backup tapes and to give the expiration date of December 31, 2001:
1> ADD DEFINE =MYBACKUP,CLASS TAPE,LABELS BACKUP,&
1> &VOLUME (NY082, NY004),EXPIRATION DEC312001
2> BACKUP =MYBACKUP,*,LISTALL
$ZSVR (the labeled tape server process) sends a mount request to the EMS log and the
MEDIACOM console for operator attention. After the operator mounts volume NY082, the
BACKUP process begins. A mount request for the NY004 tape volume is issued if the BACKUP
process fills NY082 but has not completed.
To use the DEFINE =MYBACKUP2 to specify that any scratch tape is acceptable as the BACKUP
tape, and to give the expiration date of December 31, 2001:
1> ADD DEFINE =MYBACKUP2,CLASS TAPE,LABELS BACKUP,&
1> &VOLUME SCRATCH,EXPIRATION DEC312001
2> BACKUP =MYBACKUP2,*,LISTALL
$ZSVR (the labeled tape server process) sends a mount request to the MEDIACOM console
for operator attention. After the operator mounts a scratch tape, the BACKUP process begins.
This request can use any scratch ANSI or BACKUP tape mounted on any tape drive on the
system.

Backing Up in Volume Mode

In volume mode, BACKUP transfers an entire disk volume to tape. Only the super ID (255,255)
can use the volume-mode backup procedure. When performing a volume-mode backup:
The volume being backed up must be in the DOWN disk state. If only one mirror of a mirrored
pair is being backed up, only that mirror needs to be in the DOWN state; the other mirror
can be UP.
If you are backing up only one mirror of a mirrored pair, enter the appropriate pair of
commands in the order shown:
SCF command
INFO DISK, BAD
STOP DISK
Do not back up the system disk ($SYSTEM) in volume mode without a compelling reason. If
you do this, the disk must be restored under a different name. Also, do not use volume mode
to restore $SYSTEM because the procedure requires both mirrors to be DOWN. This state is
not reasonable for $SYSTEM.
Volume-mode BACKUP/RESTORE requests are incompatible with DSM/SM virtual disks.
A volume-mode backup of a disk larger than 2 GB cannot be restored to an operating system
version prior to D30.
DP1 and DP2 file conversion is not possible during volume-mode backup procedures.

Example

For more information on the commands in this example, see the SCF Reference Manual for the
Storage Subsystem.
In this example, $DATA is the DP2 mirrored volume to be backed up.
80 BACKUP
Appendix E: CLASS TAPE
Action
Ensures that neither mirror contains any defective sectors
Puts that mirror in the DOWN state to ensure that data on the disk is consistent for all
open files on that volume
