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.
Note: This feature is not available on the EF600 or EF300 storage system.
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.
