Hi...

I use DDS3 tape to "make_tape_recovery -Av" and successful in one tape.But when recovering,system need to insert second tape to tape device.Why?

system vg00 about 13G.have over 2G files.

Try this command to backup vg00, recover and see if the problem still remains:
# make_tape_recovery -Av -x inc_entire=vg00

You are probably getting volume groups other than volume group vg00

twangs post will solve that.

Your DDS3 drive will take DDS2 tapes. You sure you have a 25 GB DDS3 tape in there?

You may not be as successful as you think. I would get a listing of the files on the tape and make sure everything you need is actually on the tape.

# mt -f /dev/rmt/?mn rew
# mt -f /dev/rmt/?mn fsf 1
# tar -tvf /dev/rmt/?mn > /tmp/ignite_files

If you have this job executing via cron, it may well be asking for a 2nd tape and you are not seeing the message.

I got burned on this one time. I thought my make_tape_recovery job was running OK, but when I tried to recover, it too asked for the 2nd tape. I didn't have it. When the system rebooted not all the files were there. I would up having to reinstall from scratch.

So make absolutely positively sure that all the files are actually on the tape.
