vSphere Replication shows the replication states of virtual machines that you configured for replication.
|State||Details for Each State|
|OK||OK, Moving, Recovering|
|Warning||Paused, OK(RPO violation), Not Active, Not Active(RPO violation), FullSync(RPO violation), Sync(RPO violation)|
|In Progress||FullSync, Sync, Initial Full Sync, Configuring|
|Error||Error, Error(RPO violation)|
Note: If a replication is in the Not Active replication state, you might have connected the source and target sites using network address translation (NAT). vSphere Replication does not support NAT. Use credential-based authentication and network routing without NAT when connecting the sites. Another cause for a Not Active replication state might be that the source virtual machine is powered off. Automatic replication works only on virtual machines that are powered on.
