The status of a Remote Mirror
There are three states of a Remote Mirror: Synchronized
The mirror status is represented with different icons in the Logical View, depending on which storage subsystem you are monitoring and whether the storage subsystem contains the primary logical drive or the secondary logical drive.
Important: Local logical drives that are participating in a mirror relationship in either the primary or secondary role and engaged in a long running operation (such as a modification operation
In the example graphic on the left, below, the primary logical drive Accounting is engaged in a long running operation and is represented with the long running operations icon for standard logical drives. It's child node, the secondary logical drive Accounting2, is represented with the Optimal, Mirror Synchronized icon for secondary logical drives. In the example graphic on the right, below, the primary logical drive Accounting has completed the long running operation and is now represented with the Optimal, Mirror Synchronized icon for primary logical drives.

The fabric connection between the storage subsystems is operational and the remote storage subsystem and the remote logical drive are accessible. Important: This icon represents the remote logical drive regardless of its true state (Optimal, Failed, Degraded, or Offline). To see the true state of the remote logical drive, open the Subsystem Management Window for the storage subsystem that contains the logical drive. |

An unresponsive remote secondary logical drive. There are four different causes that are displayed in the mouseover tooltip:
