Are you referring to XLINK? If you define XLINK volumes and systems in SYSTEM CONFIG - and XLINK FORMAT the volumes -- then you get 'LINK protection' across systems. From VM1 - attempt rw link to minidisk on VM2 that already has RW link ... your LINK will get a RC indicating the disk in in RW by 'VM2'. (not which user on VM2 - just VM2)
