CMMVC8372E Unable to set up Remote Copy data paths with partner due to unavailability of matching Remote Copy port groups.
Explanation
This error occurs when the partner returns Remote Copy configuration information that doesn't have matching Remote Copy port group IDs. This error could also occur in cases where matching local or remote ports are offline (link state is inactive), failed over to the partner node. Example, The local system has Remote Copy port group ID set to 1 while the partner has Remote Copy port group ID set to 2.
User response
Both clusters should have the same Remote Copy group port ID.
