- How synchronous mirroring works
Synchronous mirroring replicates data volumes in real time to ensure continuous availability. - Synchronous mirroring terminology
Learn how the synchronous mirroring terms apply to your storage array. - Workflow for mirroring a volume synchronously
You can configure synchronous mirroring using the following workflow. - Requirements for using synchronous mirroring
If you plan to use synchronous mirroring, keep the following requirements in mind. - Synchronous mirroring status
A synchronous mirrored pair's status indicates whether the data on the primary volume and on the secondary volume is synchronized. A mirror status is independent of the component status of the volumes in the mirrored pair. - Volume ownership
You can change the preferred controller owner in a mirrored pair. - Role change between volumes in a mirrored pair
You can change the role between volumes in a mirrored pair. You can do this by demoting the primary volume to the secondary role or promoting the secondary volume to the primary role.
