When a VM system has the PPRC secondaries online, a path group is formed with them. z/OS can't use them when this is the case.
You just need to simply vary them offline from VM. Best to not include them in the gen for the lpar totally, but if that is not possible, put them in the system config as Offline_at_IPL. z/VM does fully support PPRC - we're doing that. All controlled from the z/OS side here, though, in order to support GDPS Hyperswap. Marcy "This message may contain confidential and/or privileged information.

We currently have = a z/OS sysplex and want to put z/VM on some of the same DASD. I followed the initial install, creating the res, page, spool and work = volumes, then left the z/VM system up. The next morning the storage admins complained that all of their PPRC suspend and resume processing failed. Until z/VM was dropped, the PPRC = functions failed. The solution recommended by several people on IBM-MAIN was to mark all of= the PPRC devices 'notsupported' in z/VM. The documentation indicates PPRC is fully supported by z/VM and its guests, but if the support is that every PPRC device must be marked 'notsupported', I'd have to say that's a contradiction. Similarly,= there is nothing in the documentation about having to do anything special= when sharing DASD - such as marking the devices 'notsupported' - before = starting z/VM. Researching the archives, it appears some people are successfully using = PPRC with z/VM. Is anyone sharing PPRC volumes between z/VM and z/OS systems, and if so, = what steps do I need to take?
