That's a pity.

Yes, of course. But it will show up as a host adapter, and not as a
hard disk device, I think.

Well, my idea was almost the opposite: I would like to create some
kind of virtual hard disk on the SCSI bus which another device on the
same bus can access (no firmware changes are possible there). I want
to do this in order to avoid things like IP-over-SCSI (actually, it's
MIDI-over-SCSI in this case).
