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.
Before you begin
You must have deleted all synchronous mirror relationships. Verify that all mirrored pairs have been deleted from the storage array.
What happens next?
The controller's HBA host port 4, which was dedicated for synchronous mirroring communication, can now accept host read and write requests.
The reserved capacity volumes on the storage array are deleted.
