I've done this. The scenario I had, we switched from Microchannel to PCI, so
we couldn't move the adapters, but the RAID information is stored on the SSA
drives in some similar kind of fashion the VG information is stored on
disks. You just have to make sure that all of the disks in a RAID LUN are in
the same loop.
