That's interesting. Since you seem to know something about SCSI host
adapters with multiple SCSI buses, can you please tell us how they
show that in /dev? I'm aware of the following format:
cCtTdDsS
where <C> is the controller number (host adaptor), <T> is the SCSI
target (SCSI ID), <D> is the device number (LUN) and <S> is the stripe
(partition).
Where do they put the per-host/controller SCSI bus ID?
