We backup cyl 0 (zero) of the page packs just to avoid having to run ICKDSF to put a label on the packs. We then, of course, restore that cyl 0 at DR.
Steve From: The IBM z/VM Operating System [mailto:IBMVM@LISTSERV.UARK.EDU] On Behalf Of Crabtree, Anne D Sent: Tuesday, August 09, 2011 8:03 AM To: IBMVM@LISTSERV.UARK.EDU Subject: z/vm page packs at DR I currently back up all my z/vm packs (res,page,spool) via an adrdssu job on z/os each Sunday. 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.
