Viewing Metro Mirror and Global Mirror relationships

Introduction

To learn more about the Metro Mirror and Global Mirror feature and Metro Mirror and Global Mirror relationships, click View Tutorial to launch the Mirroring overview e-Learning module that describes how these Copy Services can help administrators migrate, back up, and recover data by creating copies of virtual disks (VDisks).

Attributes

The following attributes are displayed in the table:

Select

Allows you to select a relationship to use to perform an action from the task list.

Name

Displays the name of the mapping. You can click on the link in this column to display detailed information about the relationship.

State

Displays the current state of the relationship. The following states are possible:

Inconsistent Stopped

Indicates the primary VDisk is accessible for read and write I/O operations, but the secondary VDisk is not accessible for either. A copy process must be started to make the Secondary VDisk consistent.

Inconsistent Copying

Indicates the primary VDisk is accessible for read and write I/O operations but the secondary VDisk is not accessible for either. This state is entered after a Start command is issued to a consistency group in the InconsistentStopped state. This state is also entered when a Start command is issued with the force option to a consistency group in the Idling or ConsistentStopped state.

Consistent Stopped

Indicates the secondary VDisk contains a consistent image, but it might be out-of-date with the primary VDisk. This state can occur when a relationship is in the ConsistentSynchronized state and experiences an error that forces a freeze of the consistency group. This state can also occur when a relationship is created with the CreateConsistentFlag set to TRUE.

Consistent Synchronized

Indicates the primary VDisk is accessible for read and write operations. The secondary VDisk is accessible for read-only operations.

Idling

Indicates the master VDisks and auxiliary VDisks are operating in the primary role. Therefore, both VDisks are accessible for write operations.

Idling Disconnected

Indicates the VDisks in this half of the consistency group are all operating in the primary role and can accept read or write operations.

Inconsistent Disconnected

Indicates the VDisks in this half of the consistency group are all operating in the secondary role and cannot accept read or write operations.

Consistent Disconnected

Indicates the VDisks in this half of the consistency group are all operating in the secondary role and can accept read operations but cannot accept not write I/O operations.

Copy Type

Displays the copy type of the relationship. The following types are possible:

• Metro
• Global

Master Cluster

Displays the name of the cluster that contains the master virtual disk (VDisk) in this relationship.

Master VDisk

Displays the name of the master VDisk in this relationship.

Auxiliary Cluster

Displays the name of the cluster that contains the auxiliary VDisk in this relationship.

Auxiliary VDisk

Displays the name of the auxiliary VDisk in this relationship.

Consistency Group

Displays the name of the consistency group that contains this mapping.

Primary

Indicates which VDisk is the primary VDisk. The following values are possible:

• Any
• Master
• Auxiliary

Progress (%)

Displays the percentage of the background copy that is complete. This value can be 0% - 100%.

Actions
