Adding a node to a single-node cluster

Adding a node to a single-node cluster

All nodes in the new cluster must run the same version of VCS. The example procedure refers to the existing single-node VCS node as Node A. The node that is to join Node A to form a multiple-node cluster is Node B.

Table 8-3specifies the activities that you need to perform to add nodes to a single-node cluster.
