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.
Step 1: Select or create a consistency group for the virtual volume
Select or create a consistency group for the virtual volume.
To view the topology of a consistency group, select the group in the list. In the map that displays to the right, the Storage icon
and blue shading around a cluster indicate that the selected consistency group uses storage from that cluster.
● To add the virtual volume to an existing consistency group, select Add storage to existing consistency group and then
select the consistency group in the list.
● To filter the list of consistency groups by name, type the full or partial name of the consistency group in the Filter text
box. To filter by storage location, click the drop-down box to the right of the Filter text box, and then select the storage
location.
● To create a new consistency group for the virtual volume, select Create new consistency group.
Step 1: Create a consistency group
Complete the following fields to create a consistency group for the virtual volume.
Consistency Group Name — Type a name for the consistency group.
Consistency Group Type — Select the type of consistency group to create: Local or Distributed.
● For local consistency groups, select the cluster on which to create the consistency group.
● For Distributed consistency groups, select a detach rule. The detach rule determines if IO continues and at which cluster if
an inter-cluster link failure occurs.
NOTE: Detach rules are applied per consistency group.
Detach rule Cluster-1 Cluster-2
No automatic winner Suspends I/O
NOTE: This detach rule is generally
used if you have created external
scripts or use other programs to
determine which cluster detaches and
continues I/O during a link failure.
Suspends I/O
NOTE: This detach rule is generally
used if you have created external
scripts or use other programs to
determine which cluster detaches
and continues I/O during a link
failure.
Winner: <cluster-1> (5 seconds) Services I/O within 5 seconds Suspends I/O
Winner: <cluster-2> (5 seconds) Suspends I/O Services I/O within 5 seconds
