You need to skip over the boot header file before you can list the contents of the tape:

mt -t /dev/rmt/0m rew
mt -t /dev/rmt/0mn fsf 1
tar -tvf /dev/rmt/0mn

root@hostname # tar tvf /dev/rmt/0mn
Tar: blocksize = 4
directory checksum error

This could be a bad tape or it could be that this tape was used in a non-HP server... wrong blocksize.

If you
# tar -cvf /dev/rmt/0m /sbin
and then
# tar -tvf /dev/rmt/0m

Does it work?

If not, use a different tape. If it does, it was a blocksize issue.
