Shared Volumes

[Dusha, Cecelia Ms. WHS/ITMD]

Hello,   I would like to share a volume on multiple zVM systems.  Each system would have different area on the volume they could write to, the other areas would be read only.  Each system needs to be able to write to this volume at the same time.  Is this do-able?  If so, how is this done?   Please advice. Thank you.   Cecelia Dusha
