Server and services
When the main network is running properly, the disaster recovery servers are powered on,

there is an attempt to connect to one of the disaster recovery servers.
In a disaster recovery event, the primary servers go offline. An administrator must
manually start the services on the disaster recovery servers after the failover of the
databases is complete.
