I use these under Tru64 Unix and OpenVMS.  Tru64 see the auto-changer as 
another SCSI device and makes it possible to send commands to the 
auto-changer.  The basic, not for a fee, software included does real 
redinmentary control of the library.

I don't do that.  Under both Unix and VMS I simple use it as a normal tape 
drive and rely on the fact that when tape 0 is sent off-line the unit will 
automatically load tape 1 and so forth.  Unfortunately, when you get to 
tape 6 it won't go back to 0.  Someone needs to hit a button.

I don't know what happens when a tape is filled during a backup.  I always 
make sure I can get a full backup on one tape.  The TZ87 drive is DTL 2000 
so it will go 20/40GB.  I also have a TZ887 drive that uses a DLT 4000 
drive, it will go 40/80GB.
