Hi

In general, there are two reson that cause this error:
1. There isn't any tape in tape's drive (sometime, you forgot insert the tape :))
2. The tape's device file is not correct or hasn't installed on OS.
As above mentions, first you need to check the tape drive, does it work well (The power etc,...)? then need to check for the tape device file.
You can remove the old tape device file and reinstall again.

To remove the old device file, using:
#rm -f /dev/rmt/*
To reinstall tape device file, using:
#insf -eC tape

Check again and I sure it works!

Hope this helps
Best and regard,

Hi,

Recreating the device file will not solve the issue here. This is either media or drive failure. Try this

#mt -t /dev/rmt/0mn status

#mt -t /dev/rmt/0mn fsf 1

What does it indicates ?

Problem has been resolved by keeping cleaning DAT into DAT drive.
