You can manage multiple GAD pairs as a group by using consistency groups.
The GAD pairs in a GAD 3DC delta resync (GAD+UR) configuration must be registered to a consistency group.
Registering GAD pairs to consistency groups enables you to perform operations on all GAD pairs in a consistency group at the same time. In addition, when a failure occurs, the GAD pairs are suspended by consistency group (concurrent suspension).
For details about storage system support (microcode) for consistency groups, see Requirements and restrictions.
Note: When you register GAD pairs to a consistency
group, use the cross-path configuration. For details, see System configuration
for global-active device
solutions.
