To start replicating virtual machines, you must configure the vSphere Replication Appliance to connect to a vCenter Server instance on both the source and the target sites.
Prerequisites
Concurrent Installations of vSphere Replication in an Enhanced Linked Mode Environment
In an Enhanced Linked Mode environment, do not install vSphere Replication under more than one vCenter Server at the same time.
A conflict can arise in the creation of the service account that vCenter Server creates at the domain level for vSphere Replication authentication with vCenter Server if the following conditions exist:
- If the installation of one vSphere Replication instance overlaps with the installation of another vSphere Replication Server instance under two different vCenter Server instances.
- Those vCenter Server instances are in Enhanced Linked Mode.
The conflict does not prevent installation, but it does cause one of the vSphere Replication Server instances to fail to start, with the error message Failed to start service. The message Failed to start Authorization Manager appears in the event log for that vSphere Replication Server instance.
Configure the vSphere Replication Appliance to Connect to a vCenter Server
Configure the vSphere Replication Appliance to connect to a vCenter Server instance on both sites.
