Not that long unless its 57 Terabytes. I think it's the safe thing to do too, but z/OS is doing them this time (don't ask) and they are questioning the necessity. Would be good to have a definitive answer from IBM! (IBM disk).

It might not be necessary, but it doesn't hurt. I run eight format jobs in parallel using VM:Batch, so it doesn't take very long.

We've been formatting the whole thing. Once upon a time there was a DASD driver bug that this helped avoid, but I'm sure that has been fixed before. Marcy
