Some notes on what I did to erase a tape in Bacula.

unmount using bconsole

*unmount
The defined Storage resources are:
     1: File
     2: Scalar
Select Storage resource (1-2): 2
3307 Issuing autochanger "unload slot 2, drive 0" command.
3001 Device ""Drive-1" (/dev/nst0)" unmounted.

I used the library web front-end to move the tape into this drive then erased the label using operating system command mt:

root@bcla001:~# mt -f /dev/st0 rewind && mt -f /dev/st0 weof && mt -f /dev/st0 rewind

Manually label tape using bconsole. You probably want to use barcode labeling though. Look further down in this post.
