Marcy, I use ICKDSF to format all new DASD that is assigned to a VM LPAR, whether it's a new purchase or transfer from z/OS. 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. Dennis

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
