GAD consistency groups

You can manage multiple GAD pairs as a group by using consistency groups.

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).

When you register GAD pairs to a consistency group, you should use the cross-path configuration. For details, see System configurations for GAD solutions.

For details about storage system support (firmware) for consistency groups, see Requirements and restrictions.
