[Info-vax] I64 RAID controller P4xx family - init drives on one controller, use on a different family model

I just successfully upgraded an rx2660 from a P400 (SmartArray 400) card to a P800 (SmartArray 800) card with no loss of the RAID data. The P800 runs much faster. Yay! :-)

Thanks to everyone for posting about SmartArray compatibility.
