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.
