DDS3 & Ultrium tape backup script

[ajk_5]

Dear all,

I got a backup problem from the following script that the backup light was keep working on DDS3 tape drive and the Ultrium tape drive seems not working from the script. Anyone tell me why?

##########################################
# Perform System (DDS3) Backup

echo "Press ENTER to start backup"
read dummy
echo
echo "System (DDS3) Backup in progress ...."

#echo "enter ROOT password!"
/opt/ignite/bin/make_tape_recovery -A /dev/rmt/0m >> $ISD_MENU/backup_os.log
$ISD_MENU/writelog.sh System DDS3 Backup End

check the hardware

dmesg

all my DDS3 scripts work just fine with Ultrium drives.

I'm surprised the backups would work at all. For starters the device used for ignite tapes must be no-rewind, or the backup is useless.

/dev/rmt/0mn
/dev/rmt/1mn

Test the backup device manually

Does the following command work:
# make_tape_recovery -x inc_entire=vg00 -I -v -a /dev/rmt/1mn

Depending on the version of Ignite you have installed, you could be in trouble with the device files you specify. To err on the side of caution, use the no-rewind device files.

If you doubt the backup to the Ultrium has worked, check it out.

mt -t /dev/rmt/1mn rew
mt -t /dev/rmt/1mn fsf 1
tar tvf /dev/rmt/1mn > /tmp/recovery.log

Then compare it to the list of files in /var/opt/ignite/recovery/latest/flist.

I assume you are NOT using make_tape_recovery to do a FULL system backup (ie, including applications). If the applications live in another VG, you are not backin up the files.

Anyway, check it out and if you have any doubts, post another question.

You may remove device file and try again:
...
#echo "enter ROOT password!"
/opt/ignite/bin/make_tape_recovery -A >> $ISD_MENU/ultrium_backup_os.log
....

Twang,

What is the difference between these two commands?

#make_tape_recovery -x inc_entire=vg00 -I -v -a /dev/rmt/1mn

#make_tape_recovery -A /dev/rmt/1mn

This is what we use (run by cron once a week):
/opt/ignite/bin/make_tape_recovery -x inc_entire=vg00 -I -v -a /dev/rmt/1mn >/dev/null 2>&1
to create an interactive boot tape, -x provides flexibility.
Because new make_tape_recovery option -A doesn't quite mean vg00 as it did with make_recovery. So i like to replace -A with '-x inc_entire=vg00' when using make_tape_recovery.


/opt/ignite/bin/make_tape_recovery -Av to take backup of root vg(vg00) includes all files the vg00 into the archive(/dev/rmt/1mn). If no device file provided, it will be on the default tape drive /dev/rmt/0mn.

I did update the script regarding Twang's information and try again. The first part (DDS3 tape backup) is ok. The second part (Ultrium tape backup) is still go through each step, but the Ultrium tape drive didn't backup data. Please help!

Thanks a lot!

Can you manually perform the backup via command-line successfully?
