I read a similar discussion on the mailing list about assign. We don't have any tools to share tapes between 1 VM & 20 MVS. Something has been developped in the past which is not really up-to-date. We remarked it needs too much CPU to do its work.
I project to use our VM to be THE platform to share tape drives between lpars in a normal prod or when we do our disaster recovery tests (MVS are lvl2). We only have ATL robots. I just tested one thing that could give other id eas to investigate. I have attached a drive with the multiuser option. In parallel it was use d by a MVS. Then I tested the dfsmsrm q dev xxx (assign cmd and I was surprised to get the volser that was mounted in MVS. If dfsmsrm is able t o send back this info, can't it be able to send back the part number or the MVS partname too ? That could be great. And (What VM diag D0 would say if a tape is mounted in a MVS ?) Alain Benveniste
