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.
Test communication for synchronous mirroring
You can test the communication between a local storage array and a remote storage array to diagnose possible communication problems for a mirrored pair that is participating in synchronous mirroring.
Change role between volumes in a mirrored pair
You can perform a role reversal between the two volumes in a mirrored pair that are participating in synchronous mirroring. You change the role between volumes in a mirrored pair for administrative purposes or in the event of a disaster on the local storage array.
Change synchronization settings for a mirrored pair
You can change the synchronization priority and resynchronization policy that the mirrored pair uses to complete the resynchronization operation after a communication interruption.
Remove synchronous mirror relationship
You remove a mirrored pair to remove the mirror relationship from the primary volume on the local storage array and the secondary volume on the remote storage array.
