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: Tasks to add a node to a single-node cluster specifies the activities that you need to perform to add nodes to a single-node cluster.

| Set up Node B to be compatible with Node A. | See Setting up a node to join the single-node cluster . |
| - Add Ethernet cards for private heartbeat network for Node B. | See Installing and configuring Ethernet cards for private network . |
| - If necessary, add Ethernet cards for private heartbeat network for Node A. | |
| - Make the Ethernet cable connections between the two nodes. | |
| Connect both nodes to shared storage. | See Configuring the shared storage . |
| - Bring up VCS on Node A. | See Bringing up the existing node . |
| - Edit the configuration file. | |
| If necessary, install VCS on Node B and add a license key. | See the Arctera InfoScale Installation Guide for installation instructions. |
| Make sure Node B is running the same version of VCS as the version on Node A. | |
