As Joshua pointed out, it would help to mention something about the OS
with which you're working.

I have not used that model, but I do have a different (re-badged) Breece
Hill device working under FreeBSD-STABLE, using the chg-chio changer.

I needed to make changes in order for it to work:

* To the chg-chio Perl script itself -- I sent the patches that I found
  appropriate in to amanda-hackers a couple of months ago.

* To /usr/src/sys/cam/scsi/scsi_ch.c; it seems that (per one of the
  FreeBSD SCSI developers who has way more clue than I do) that the
  device was lying about how big a buffer would be required to hold
  the result from a SCSI "inquiry" request.  The patch was really gross:
  I just multiplied the amount of buffer (as calculated) by 4 before
  the malloc() was done.  (If someone really wants this patch, please
  mail me privately -- this isn't an amanda issue.)

Peace,
david
