For "Site A"
Edit your "Site A" ServAssure NXT Inventory file and add the following groups and hosts:
Copy the Cassandra groups and hosts from your "Site B" inventory, but rename the groups as shown in the example. The groups MUST be prepended with "site_b_" to avoid interfering with the existing Cassandra groups and hosts in your "Site A" inventory. The "Site B" Cassandra nodes must be named exactly how they are in the "Site B" inventory and must be reachable from the Ansible server.
