The VVR replication settings determine the replication behavior between the Primary RVG and a specific Secondary RVG. VVR behaves differently based on the settings for mode of replication, SRL overflow protection, and latency protection, depending on whether the Secondary is connected or disconnected. To use the replication settings effectively in your environment, it is important to understand how each replication setting affects replication when the Primary and Secondary are connected and disconnected. A Secondary is said to be disconnected from the Primary if the RLINK becomes inactive because of a network outage or administrative action.
VVR enables you to set up the replication mode, latency protection, and SRL protection using the replication attributes. Each attribute setting could affect replication and must be set up with care.
