If you have two sites and reinstall the vSphere Replication Management Server appliance or reset its database, configuring replications fails.


The other site contains information on the old appliance and database, and prevents you from configuring new replications. You might see the following error message:
Unable to configure replication for virtual machine VM_name because group group_name cannot be created.
Another virtual machine configured_VM_name}' that has the same instance UUID instance_UUID already exists on protection site source_site_name.


  1. Reinstall VRMS at the other site or reset its database.
  2. Connect the sites and register any additional vSphere Replication Server appliances.
  3. Remove any temporary hbr* files left over from the target datastore folders.
  4. Configure all replications, reusing the existing replica .vmdk files as replication seeds.
