In a hot failover, each monitored Active component has a hot Standby sibling that must be kept up-to-date at all times. The Standby component gets its topology and event data from the Active component. Thus, while the Active component is connected to the underlying Domain Managers, the Standby only connects to the Active component to synchronize with it. On the Standby component, Failover Manager automatically disables all underlying Domain Managers. Therefore, the configuration procedure of the Active component and that of the Standby component differ slightly.
