Well, yes on both counts. Any HVD disks should be detected... but at the time these boxes were made, there were supposed to be certain differences between HP and regular disks. Or maybe that was just HP marketing. At any rate, there _was_ (and still is, BTW) a way to recognize a HP disk by the firmware - and there were differences between "workstation" and "server" disks too, _and_ IIRC "workstation" disks weren't "expected to work" in servers, the other way round it was "expected to work" but "unsupported" or something. Don't remember. If I only could remember what the exact identification thing was ... maybe a letter somewhere in the firmware version string. But since HP-UX 10.20 by the latest, probably earlier too, some people have been using whatever disks they get as long as the SCSI interfaces are compatible. I've never heard of problems. Me? I recycle old HP disks in PCs... -- Mikko Nahkola Tre-IN sysadmin
