Adding an instance to the cluster or removing an instance from the cluster involves:
Adding the host node to VCS or removing the host node from VCS (optional if removing an instance)
Adding or removing the instance
You can perform the tasks in either order, but you cannot start the instance until both tasks are complete. See Chapter 14, “Administering Clusters with the Adaptive Server Plug-in,” and Chapter 15, “Administering Clusters Using sybcluster.”. For information about adding a node to a VCS cluster, see “Adding a node to SF Sybase CE clusters” in the SF Sybase CE Administrator's Guide.
