To set the consistency group’s visibility property to both clusters:
VPlexcli:/clusters/cluster-1/consistency-groups> set TestCG::visibility
cluster-1,cluster-2
To set the consistency group’s visibility property to cluster-1:
VPlexcli:/clusters/cluster-1/consistency-groups> set TestCG::visibility cluster-1
To set the consistency group’s visibility property to cluster-2:
VPlexcli:/clusters/cluster-1/consistency-groups> set TestCG::visibility cluster-2
Setting the storage-at-clusters property
By default, the consistency group’s storage-at-clusters property is set to empty.
The storage-at-clusters field tells metro node at which cluster the physical storage that is associated with a
consistency group is located. If visibility is set to one cluster, then storage-at-clusters must be the same
as visibility. If visibility is set to two clusters (1 and 2), then storage-at-clusters can be one of:
● cluster-1
● cluster-2
● cluster-1,cluster-2
A volume that does not have local storage at every cluster specified by the storage-at-clusters property of a consistency
group, cannot be added to the consistency group.
5. Use the set command to configure the consistency group’s storage-at-clusters property
VPlexcli:/clusters/cluster-1/consistency-groups> set TestCG::storage-at-clusters
cluster-1,cluster-2
6. Optionally, use one of the consistency-group set-detach-rule commands to apply a detach rule.
For example, configure the detach-rule as active-cluster-wins:
VPlexcli:/clusters/cluster-1/consistency-groups/TestCG> set-detach-rule active-
cluster-wins
7. Use the ll command to display the new consistency group.
See Table 16 Consistency group field descriptions for descriptions of the fields in the display.
Adding volumes to a consistency group
A maximum number of 1000 volumes can be added to a consistency group.
About this task
All volumes used by the same application should be grouped together in a consistency group.
Only local volumes can be added to synchronous consistency groups with visibility and storage-at-cluster set to the local
cluster.
Remote volumes can be added to synchronous consistency groups with visibility set to both clusters and storage-at-cluster set
to one cluster.
Distributed volumes can be added to synchronous consistency groups with visibility set to both clusters and storage-at-cluster
set to both clusters.
To add virtual volumes to an existing consistency group, do the following:
