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.

Steps

  1. Select Storage › Synchronous Mirroring.

  2. Select Uncommon Tasks › Deactivate.

    The system displays a confirmation.

  3. Select Yes to confirm.

Results

  • 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.
