Normally, I suppose you would. But the packs are preformatted for us.

In my experience, you can end up with paging errors if the dasd isn't initialized/formatted. Haven't tried just cylinder 0 though, so I could be wrong..

At the DR site, I run an adrdssu restore job for these packs. This method works fine, however, I'm wondering if backing up the page packs is necessary? I was thinking that maybe I could backup only 1 page pack so that I can get z/vm up and then just init the remaining packs after coming up. Since the page packs are listed as cpvols in system config, would z/vm even come up if it couldn't find all of them? Seems like a waste of time to back them up... At DR site, we bring up a z/os "rescue" system in order to run restore jobs for both z/os and z/vm volumes. Afterwards, our z/vm and z/os systems run as second level guests. Maybe I need a "rescue" z/vm system as well? Just wondering what everyone else does. Anne D.
