Hi,
I had a problem with a TLZ09-DB DAT drive that
would not rewind tapes correctly (but that otherwise
was working correctly).
The solution was to use
mt -f /dev/rmt1h offline
instead of
mt rewind
mt unload
because
1. mt defaults to rmt0. In my case this was not the problem because
for some reason /dev/rmt1h and /dev/rmt0h correspond to the same
device (we have only one dat-device). Why I have both /dev/rmt0h
and /dev/rmt1h is not clear to me...
2. use /dev/rmt1h and not /dev/nrmt1h because the 'n' causes the
drive to not rewind the tape. I should have known this since
I use this to make multiple backups to one tape...
so I changed my backup-script to look like this:
logfile='/home/roussea/tarlog4'
print "Backup started at $(date)" > $logfile
df -k >> $logfile
/local/bin/tar -cvzf /dev/nrmt1h --exclude-from='/dontbckp' /home3
1>>$logfile 2>&1
/local/bin/tar -cvzf /dev/nrmt1h --exclude-from='/dontbckp' /home4
1>>$logfile 2>&1
/local/bin/tar -cvzf /dev/rmt1h --exclude-from='/dontbckp' /home
1>>$logfile 2>&1
print "Backup completed at $(date)" >> $logfile
mt -f /dev/rmt1h offline
and now it seems to be working fine.
