Thanks for all of the information. I'm running Gentoo Linux on a Sun
Ultra 2. the TAPE.CHANGER document is just what I was looking for. mtx
and mt all work fine so my only problem was in determining how to
configure amanda.

How do I configure amanda to handle a Breece Hill Q7 tape changer? It
has two disks and 28 tape slots. I am guessing that I need to set
tpchanger to "chg-scsi" but how do I tell it what the tape changer
device is, and about both of the drives and the number of tapes etc.?
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
