To configure the VMware vCloud Availability solution, in a single site perform an initial configuration of vCloud Availability Replication Manager, vCloud Availability vApp Replication Manager, vCloud Availability Replicator and vCloud Availability Tunnel, register the services in the site, and pair cloud sites.
As a best practice, configure all services in one site, register the vCloud Availability Replicator instance with the vCloud Availability Replication Manager instance in the same site, and to allow for pairing, perform an initial configuration and registration of the second site.
After configuring a vCloud Availability service, you can validate that the setup is complete by opening the service management interface to the System Monitoring page. On that page, the entries are green to indicate successfully configured services, and red entries indicate an incomplete setup.
