Just to clarify, is that 2 separate SCSI controllers, as in the onboard plus
a PCI-X card?
If it is two different channels of onboard SCSI, then they can only go in
the same LPAR as they are the same PCI resource, which would mean only one
LPAR unless you use VIO (and that would mean no 5.2)... It's like the dual
port Ethernet on the motherboard. The two ports can only be allocated into a
single LPAR.
