Working with Clusters
The VERITAS Volume Manager includes an optional cluster feature that
enables the Volume Manager to be used in a cluster environment. To
activate the cluster feature, you must obtain a license for the Volume
Manager cluster functionality.
After adding a Volume Manager cluster license to the machine, you must
restart the Storage Administrator server to enable cluster support in the
Storage Administrator. When a cluster license is present on a machine,
the Storage Administrator displays a Clusters icon in the object tree
(even if the machine is not currently set up as a node in a cluster). When
a cluster is shown in the tree, all active/inactive nodes that are members
of the cluster are displayed in the tree.
