- 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 mirroring terminology
Learn how the asynchronous mirroring terms apply to your storage array. - Workflow for mirroring a volume asynchronously
You configure asynchronous mirroring using the following workflow. - Requirements for using asynchronous mirroring
If you plan to use asynchronous mirroring, keep the following requirements in mind. - 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.
