Tape drive problems

Recently we had a problem with a CPU card on our SunFire V880 which has Solaris 9 OS. we removed the card and there was also a problem with our usr which was accidentally deleted. We able to restore the usr but now we having a problem with our tape drive.
Previously we could write to the with
tar cvf /dev/rmt/0n
and could even issue commands like
mt rewind
mt -f /dev/rmt/0n fsf 2
Now when we issuue those command we get messages like
/dev/rmt/0n: no such file or directory

A look at the /dev/rmt/0n reveals that files which previously were similar to 0 0n 0cb 0n ......
are now been changed to 2 2n 2cb 2n.....
and we can only tar with /dev/rmt/2n and cannot issue the mt command.
What's gone gone wrong and how can get back our mt command working together with the /dev/rmt/0n option.

try to disconnect the drive and run "devfsadm -Cv" to clear the device entries. after that reconnect the tape and run "devfsadm -v" to recreate the device entries.

Hey, is there more than one drive connected to this host? Did that drive work at any time so far? Could it be, that there is something like a driver for this device is missing after the restore?

To fasten up, you could also use devfsadm -Cv -c tape...
