I can use mtx to get tape status.  I have not tried to load or unload
a tape.  Basically, assuming everything works and the problem lies
with amanda, how do I use amtapetype?  What device do I use?

[root@alienraid ~]# mtx -f /dev/sg1 inquiry
Product Type: Tape Drive
Vendor ID: 'HP      '
Product ID: 'Ultrium 3-SCSI  '
Revision: 'G24H'
Attached Changer: No
[root@alienraid ~]# mtx -f /dev/sg2 inquiry
Product Type: Medium Changer
Vendor ID: 'OVERLAND'
Product ID: 'LXB             '
Revision: '0107'
Attached Changer: No

Trying amtapetype with either of these devices fails.  Any hints?   I
can try the other things you suggested btw, such as tar or load/unload
a tape, and will let you know if they don't work.

Thanks

Nick

Before trying any amanda commands, I'd suggest you try some of
your system commands to see if 'anything' can talk to your
changer and tapedrive.  Amanda just adds another layer of
complexity that is not needed yet.

Can you use:

mtx to get status, load a tape, move to another slot, etc.
mt  to get status, eject a tape, move to the end of a tape, rewind

dd to write a file to the tape and after mt rewind, read the file
from the tape

tar to create an archive and write it to the tape, then recover it
