[Gllug] SCSI devices

[Xander D Harkness]

Yes mine is HP and does work in this fashion.  I can change tapes with 
mtx and I am now working to try to get it to write some data. ;-)

It threw me that there were not several addressable devices as much of 
the literature suggests, and also there were many devices masquerading 
as the same object.

Cheers
Xander
