Manage synchronous mirrored pairs
You can test the communication link between a mirrored pair, suspend and resume synchronization, change the role of volumes, change synchronization settings, and remove the synchronous mirror relationship.
Deactivate synchronous mirroring
You can deactivate the Synchronous Mirroring feature on a storage array to re-establish normal use of host bus adapter (HBA) host port 4, which was reserved for mirror data transmission.
