Hi,
The frist step U should use command
# ioscan -fnC tape

Then U find the state of your /dev/rmt/1mn. If that is
UNCLAIMED then U should know here is a HW problem.
If that tape is the new install, maybe U should install the correct driver in kernel.

BTW, check the tape in the tape drive, U can try change another tape.
good luck to U

And verify that the tape is not write protected. It would give the same error
