I have an HP A3400A autoloader. (This appears to be the same actual
hardware that you get if you buy the HP 120000e)
Basically, It's a 6-tape magazine-based DDS2 DAT drive.

We've had this thing about 3 years, and I've been horsing around with it
now and again, and now it finally works with HP-UX.
(It always worked as a tape drive, the new achievement is being able to
load and unload tapes from software).

>From my reading of the SCSI-HOWTO, and the various HP-UX manuals, I think
the way it works is roughly analagous to the "generic scsi" driver in
linux.  There is a scsi device that functions as a bare-bones "pass-thru"
and other programs (in this case the "mc" command) provide rudimentary
interfaces.

Anyway, it looks like the HP-UX "Scsi Pass-through" or "spt" device is
equivalent to the Linux "Generic SCSI" kernal driver.

Does anybody know of a program that talks to this device and provides some
sort of command interface?  

Or alternatively is there anyone who happens to know what scsi commands
would have to be sent to this device? I'm not a real C programmer, but I
could play one on TV:).

I also note that over in the FreeBSD camp they have a "ch" device, accessed
with the "chio" command.  Some Linux equivalent for this arrangement could
also solve my problem.
