How asynchronous mirroring works
Asynchronous mirroring copies data volumes on demand or on a schedule, which minimizes or avoids downtime that might result from data corruption or loss.
Asynchronous mirror status
The mirror status defines the state of mirror consistency groups and mirrored volume pairs.
Volume ownership
You can change the preferred controller owner in a mirrored pair.
Role change of a mirror consistency group
You can change the role between mirrored pairs in a mirror consistency group. You can do this by demoting the primary mirror consistency group to the secondary role, or by promoting the secondary mirror consistency group to the primary role.
