You can view all Metro
Mirror or Global Mirror consistency
groups at one time on the Viewing Metro or Global Mirror Consistency
Groups panel in the SAN Volume Controller Console.
Attributes
The
following attributes are displayed in the table:
- Select
- Allows you to select a consistency group to use to perform an
action from the task list.
- Name
- Displays the name of the consistency group. You can click on the
link in this column to display detailed information about the consistency
group.
- State
- Displays the current state of the consistency group. The following
states are possible:
- Inconsistent Stopped
- Indicates that the primary VDisk is accessible for read and write
input/output (I/O) operations, but the secondary VDisk is not accessible
for either operation type. You must start a copy process to make the
secondary VDisk consistent.
- Inconsistent Copying
- Indicates that 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 that 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but it might be out of date with the primary VDisk.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 that the primary VDisk is accessible for read and write
I/O operations. The secondary VDisk is accessible for read-only I/O
operations.
- Idling
- Indicates that the master VDisks and auxiliary VDisks are operating
in the primary role; both VDisks are accessible for write I/O operations.
- Idling Disconnected
- Indicates that the VDisks in this half of the consistency group
are all operating in the primary role and can accept read or write
I/O operations.
- Inconsistent Disconnected
- Indicates that the VDisks in this half of the consistency group
are all operating in the secondary role and cannot accept read or
write I/O operations.
- Consistent Disconnected
- Indicates that the VDisks in this half of the consistency group
are all operating in the secondary role and can accept read I/O operations
but cannot accept write I/O operations.
- Empty
- Indicates that the consistency group does not contain any relationships.
- Copy Type
- Displays the copy type of the relationship. The following types
are possible:
- Master Cluster
- Displays the name of the cluster that contains the master virtual
disk (VDisk) in the relationship.
- Auxiliary Cluster
- Displays the name of the cluster that contains the auxiliary VDisk
in the relationship.
- Primary
- Indicates which VDisk is the primary VDisk. The following values
are possible:
- Relationship Count
- Displays the number of relationships that are in this consistency
group.
