Field/Column Description
System ID The array's ID number for the storage volume.
Initiator The Port WWN of the metro node backend port.
Target The Port WWN of the storage array target port.
LUN The Logical Unit Number for the storage volume.
Consistency group properties
Consistency
Group Name
The name of the consistency group. You can change the name in the properties dialog box.
Detach Rule
(metro node
Metro only)
The detach rule that applies to the consistency group. It designates which cluster detaches if the clusters
lose connectivity. Possible values:
no-automatic-winner — The consistency group does not select a winning cluster.
winner <cluster-name> <delay> — The cluster specified by <cluster-name> is declared the winner after
the inter-cluster link outage lasts more than the number of seconds specified by delay. If a consistency
group has a detach-rule configured, the rule applies to all volumes in the consistency group, and overrides
any rule-sets applied to individual volumes.
Visibility Lists the clusters at which the consistency group is visible.
Storage At
Clusters
Indicates if the volumes in the consistency group use storage from one cluster, or both clusters.
Device component properties
Component Name
The name of the device's component. You can change the name from this dialog box.
Geometry The underlying RAID structure of the device.
Health The overall health of the component.
Health
Indications
A list of reasons for the component's unhealthy state.
Operational
Status
Indicates how the component is functioning in the cluster. See Operational states.
Service Status Indicates whether I/O can proceed on the device. See Service states.
Device properties
Device Name
The name of the top-level device. You can change the name in the properties dialog box. The name must
be unique across clusters.
Geometry The underlying RAID structure of the device.
Virtual Volume The name of the virtual volume created on the device.
Locality Indicates where the device is visible: Local or Remote.
Cluster The name of the cluster to which the device belongs.
Block Count The number of blocks in the underlying extent.
Block Size The size of the data blocks used internally when managing I/O. The block size determines the granularity
of storage volume I/O and the rebuild rate of distributed devices.
Capacity The size of the device.
