Working with Clusters

VxVM includes an optional cluster feature that enables VxVM to be used in a cluster

environment. To activate the cluster feature, you must obtain a license for the VxVM

cluster functionality.

After adding the cluster license to the machine, you must restart the VxVM server to

enable cluster support. When a cluster license is present on a machine, VxVM displays a

Clusters icon in the object tree (even if the machine is not currently set up as a node in a

cluster). Whena clusteris shown in the tree,all active/inactive nodes that are members of

the cluster are displayed in the tree, as shown in “Tree/Grid View of a Cluster.”
