You MUST use full-pack mdisks (preferred) or dedicated volumes whenever you share with another z/OS or z/VM system that is running in a separate LPAR. If all users are on the same VM system (e.g. first level RACF/VM sharing with second-level z/OS), then small minidisks can be used. We have solutions on the drawing board, with the premise that shared dasd is not a viable long-term strategy for database synchronization. Alan Altmark z/VM Development IBM Endicott
