Remote copy source and backup virtual volume WWNs are not the same
In a Remote Copy peer persistence configuration, a source and backup virtual volume do not have the same WWN.
A source and backup virtual volume in a Remote Copy peer persistence configuration will have same WWN only if the Remote Copy configuration is 1-to-1. And both the source and backup storage system have an HPE 3PAR Peer Persistence license enabled.
This issue is known behavior. No action is required.
