Help - ontape question

Hi there, Is there any way to see is the data from an ontape -s -L 0 was writen to the tape. Such as the tar command in unix , tar tvf /dev/rmt/0. We have had problems with this in past and are planning to upgrade our Raid system to a differant size striping and want to make sure we can read the backups we make. This also goes for the ontape -c command . An way to see if anything has gone to the tape. thanks in advance, Pat pmilitzer@ultracom.com
