About the cluster UUID

When you install VCS using the product installer, the installer generates a universally unique identifier (UUID) for the cluster. This value is the same across all the nodes in the cluster. The value is defined in the CID attribute.

See Cluster attributes

If do not use the product installer to install VCS, you must run the uuidconfig.pl utility to configure the UUID for the cluster.

See Configuring and unconfiguring the cluster UUID value
