How many drives do you have physically / do you expect.
I would try to remove the device completely from the ODM -
rm -dl rmt3
and if possible reboot. If the connection between the device and your server is ok, than it should be available afterwards, if now I'd call hardware support and ask them for help.
Good luck,
kind regards

The problem about the tape defined was, on the switch there wasnt zone about this drive (rmt3) that�s why I can�t see on my server. I check in others servers and the same thing (tape drive defined).
