You use the VCS Cluster Configuration Wizard (VCW) to add one or more nodes to an existing VCS cluster.
Prerequisites for adding a node to an existing cluster are as follows:
Verify that the logged-on user has VCS Cluster Administrator privileges.
The logged-on user must be a local Administrator on the system where you run the wizard.
Verify that Command Server is running on all nodes in the cluster. Select Services on the Administrative Tools menu and verify that the Veritas Command Server shows that it is started.
Verify that the Veritas High Availability Daemon (HAD) is running on the node on which you run the wizard. Select Services on the Administrative Tools menu and verify that the Veritas High Availability Daemon is running.
