The new node to join the existing single node that runs VCS must run the same operating system.
To set up a node to join the single-node cluster
Do one of the following tasks:
If VCS is not currently running on Node B, proceed to step 2.
If the node you plan to add as Node B is currently part of an existing cluster, remove the node from the cluster. After you remove the node from the cluster, remove the VCS RPMs and configuration files.
If the node you plan to add as Node B is also currently a single VCS node, uninstall VCS.
If you renamed the LLT and GAB startup files, remove them.
