CMMVC6475E The Add relationship to group task cannot be initiated because the master cluster of the relationship that you are attempting to add to the group is the auxiliary cluster of the group, and the auxiliary cluster of the relationship that you are attempting to add to the group is the master cluster of the group.

Explanation
All of the relationships within a group must have
the same master cluster as the group and must have the same auxiliary
cluster as the group. The determination as to which cluster is assigned
as the master cluster when you create a relationship or consistency
group is based on the cluster from which you submit the task.

User response
Perform one of the following three options:

Delete the group and create the group so that the master cluster
of the group is identical to the master cluster of the relationship
and the auxiliary cluster of the group is identical to the auxiliary
cluster of the relationship.

Delete the relationship and create the relationship so that the
master cluster of the relationship is identical to the master cluster
of the group and the auxiliary cluster of the relationship is identical
to the auxiliary cluster of the group.

Specify a group and a relationship that have identical master
clusters and identical auxiliary clusters.

Resubmit the task.
