The drivers are ok. Post a ls -l for the files you are trying to backup. Also a lssf /dev/rmt/0m (or whatever tape device you are trying to use.

# ls -alt ptest.txt
-rw-rw-rw- 1 root sys 3878 Mar 28 2003 ptest.txt
# lssf /dev/rmt/0m
stape card instance 2 SCSI target 0 SCSI LUN 0 at&t best density available at ad

Nowhere in your first post is any mention of the ptest.txt file. It doesn't do me one bit of good to see the output of ls on some random file. Read your own first post. Those are the file whose output I need to see.
