Frankly, I don't know. Hoff may have a way. Backup does a callback to hook
the
boot stuff up, including creating the partition headers - I don't know if
there is a
way to have backup do this so that a new GUID isn't created.

I've never really even though about it. I'll see if I can find out. But as
to
the SCSI port on the back, we routinely use these for external drive
shelfs. The original box had a sticker (I think for HP-UX) that said it
wasn't supported. And early on, VMS didn't have a U320 LSI driver
(so we required a U160 LSI board). But that hasn't been the case
for a long time.
