I guess we'll have to disagree on this one. To me, Fred's explanation:
"Firstly make sure you have a SE SCSI host adaptor in addition to the
one in
the core IO. A SE bus can only take 7 devices and if all 7 are disks
that
bus will get stressed. If you have to add a SCSI card and this is a
production system, it gets a bit complicated/risky and I suggest paying
HP
or 3rd party support for some assistance."
seems to pretty clearly--and incorrectly--indicate that any arbitrary
"SE SCSI host adaptor" that might be available "can only take 7
devices".
