this is the error i receive when trying to backup to a dlt tape drive using fbackup. i know very little about hp-ux, so i have no idea how to troubleshoot this problem and have not had much luck searching for info on the web. thanks.

okay

First of all check

1. mt -f /dev/rmt/0mn status

Paste the command and the error message you are getting.

Thanks

What OS version are you using? status is valid on 11.00.

Can you use fuser(1m) to find who is using it?
# fuser -f /dev/rmt/0m

The tape drive could also be jammed.

use "fuser -ku /dev/rmt/0mn"

we are using B.11.00... i'm not sure why the 'status' option doesn't work.

the problem is resolved. i'm not sure how... someone must have had a lock on the tape drive or maybe a process hung up. i'm not sure but thank you very much for your help everyone.
