Same problem here. VM Sysprogs needed to detach mirror targets from VM.
VM apparently attaches all DASD unless told otherwise.

Subject: z/VM and Mirrored DASD owned by z/OS

We're bringing up z/VM for the first time. Initial volumes are in the shared 
pool
with other z/OS volumes on a HTC something-or-other. Some of the z/OS
volumes are mirrored, but not the VM volumes - yet anyway.

We have a daily process that suspends and reestablishes the mirrors for DR
purposes. The first morning the VM LPAR was left running, the mirrors would
not reestablish for any of the 800+ mirrored volumes. Error was "ANTP0120I
COMMAND CONFLICTS WITH ESTABLISHED PPRC DEVICE STATE." Previous
messages indicate all of the volumes were in a suspended state.

Eventually someone decided to reset the VM lpar, and about that time (but
not exactly) the storage team was able to reestablish the 800+ pairs again.

I don't see any connection, but has anyone else had a similar problem? I also
checked the manuals, and see nothing that indicates I need to do anything
special for z/VM.
