AFAIK, the last real CKD device that IBM announced was the 3350; the 3375,
3380 and everything since have been FBA under the covers, and that was
well before the advent of RAID.

Because there's a lot more involved than just drivers and because it would
be a nightmare to do it without active cooperation from IBM.
