Hi,

Check man make_tape_recovery:

make_tape_recovery -x inc_entire=vg00 -x inc_entire=vg01 etc.

Hi Idriz,

If that's *all* the VGs it would be as follows:

make_tape_recovery -Ivx inc_entire=vg00 -x inc_entire=vg01 -x inc_entire=vg02

Assuming your tape dev is /dev/rmt/0mn - else you'd also need

-a /dev/rmt/Xmn

where X=tape instance #

NTH,

man make_tape_recover

the -x options is for that.
make_tape_recovery -x inc_entire=vg00 -x inc_entire=v01 -x inc_entire=vg02 -v -I -a /dev/rmt/0mn

Idriz,

Just a caution - that's not really the intent of make_tape_recovery. Ignite make_tape_recovery is supposed to be just that - a recovery tool to get your system back up quickly by booting of the tape and reloading your root volume: vg00. From there you would use conventional backup/restore products to recover the rest of your data. Make_tape_recovery does not provide any of the niceities of more sophisticated backup products such as incremental backups, easy restore of individual files/directories, etc.

I would strongly suggest that you use make_tape_recovery just for vg00 and the backup the rest of your data using conventional means.

If you want this to ignite all vg's (even newer ones you add later) you can use the script: -

CMD="make_tape_recovery"

for VG in `/usr/sbin/vgdisplay | grep "VG Name" | cut -d\/ -f3`
do
CMD=$CMD" -x inc_entire=$VG "
done

CMD=$CMD" -v -I -a /dev/rmt/0mn"

$CMD

NOTE: There is a bug in make_tape_recovery when saving multiple VG's. It will NOT save all the vg00 files! You'll see this warning when you run make_tape_recovery with multiple VG's on the command line. HP has acknowledged the bug and will have a fix next quarter.

That being said, it is very important NOT to make a recovery tape with multiple VGs. The MOST common use of a backup tape is to recover a few files or perhaps a directory. make_tape_recovery is designed ONLY to erase all the disks and reinstall. If your system uses LVM mirroring, you must manually configure this after reloading.You must always interact during the reload to make sure the right disks are being defined in VG00, especially with mirroring. And make_tape_recovery cannot save any files larger than 2Gb.

True, you can play with the mt command to position the tape and use pax to restore some files but that is incredibly slow compared to fbackup. The strategy should be:

1. Download the latest version of Ignite/UX.
2. Run make_tape_recovery during a quiet time on the system.
3. Use fbackup to backup all files and directories for fast restores.
