He reported off-line that indeed they were on a 3990 CU. Even when the disks have been used before (i.e. he did ICKDSF install) then that does not explain whey the dasd driver refuses to pick them up. Now I probably did not stare long enough to the source, but it looks like there are no fixed constants in it, so that should be fine. For what I could tell it looked like there is support for 3390's on a 3880 and I figure that could be a typo there.
