Monitoring the Enhanced Remote Mirroring Status

The status indicates whether the data on the is replicated identically (fully synchronized) on the . A mirror status is independent of the component status of the underlying in the mirrored pair. The primary logical drive icons and the secondary logical drive icons in the Logical pane indicate both the state of the logical drive as well as the state of the remote logical drive mirror.

Enhanced Remote Mirroring can be in one of four statuses: Synchronized, Synchronization in Progress, , and .

The Enhanced Remote Mirroring status is represented with different icons in the Logical pane, depending on which 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 role or the secondary role and engaged in a long-running operation (such as a ) show the long-running operations icon for until the operation completes. An informational tool tip identifies the logical drive as either a primary logical drive or a secondary logical drive.

When the Storage Subsystem that You Are Monitoring Contains the Primary Logical Drive

If you have opened the Subsystem Management Window for the storage subsystem that contains the primary logical drive, then the mirror status is indicated by these icons in the Logical pane.

Representation of the Remote Secondary Logical Drive

If you are monitoring the storage subsystem that contains the primary logical drive, then the remote secondary logical drive is represented by the icons in the Logical pane as shown in these two tables.

Icon Remote Secondary Logical Drive Representation

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 status (Optimal, Failed, Degraded, or Offline). To view the true status of the remote logical drive, open the Subsystem Management Window for the storage subsystem that contains the logical drive.

Unresponsive remote secondary logical drive. One of four different causes appears in the informational tool tip:
  • The remote logical drive is not accessible.
  • The remote storage subsystem is not accessible.
  • The fabric connection between the storage subsystems is not accessible.
  • The remote logical drive cannot be updated with a new World Wide Identifier (WWID).
The Enhanced Remote Mirroring has been suspended. When Enhanced Remote Mirroring is in a Suspended status, no attempt is made to contact the secondary logical drive. Any writes to the primary logical drive are persistently logged in the .
When the Storage Subsystem You Are Monitoring Contains the Secondary Logical Drive

If you have opened the Subsystem Management Window for the storage subsystem that contains the secondary logical drive, then the mirror status is indicated by these icons in the Logical pane.
