I think that when you use DDR you have to think PHYSICAL disk,
since DDR does not have a concept of minidisk. That said it stands
to reason that whenever you copy from one PHYSICAL disk address ie
CYL 0 to a different PHYSICAL disk address ie CYL 1 you must use
the reorder option.
DDR copies very low level data ie H0 R0 record.
Do you have to use reorder, or does CP DEFINE MDISK work well
enough? I use DEFINE MDISK habitually, but I don't remember ever
explicitly using reorder. It may be that I always defined my source
minidisk as starting at cyl 0 going for 3338, and my target as 1 for
3338 though. I haven't actually needed to do it in a while.
