Hi,

First you run the command insf -e or insf witout any option . This will create the device files for new installed hardware or device file deleted or corupted. Then check the devive file for the particular tape and run the fbackup command.

Error you have listed seems to be some issue with device file only.

The error message is fairly clear: there is no device called c0t1d0BEST. Unfortunately, insf creates these lengthy names which are duplicates of the shorter (easier to remember) names. To see the icentical device files:

ll /dev/rmt | sort -k6

The device file that will work with fbackup (and easy to remember) is /dev/rmt/0m (or 0mn). The trailing 'n' refers to no-rewind which is only meaningful to simple tools like tar or cpio). fbackup controls all tape movement so the automatic features in specfic defice files are not important.
