vSphere Replication includes an embedded vSphere Replication Server by default. If you want to disable the embedded vSphere Replication server, you can do so using ssh.

Prerequisites

Make sure no replications are using the embedded server. Stop the replications or move them to a different server.

Procedure

  1. Use ssh into the vSphere Replication appliance and type: 
    # /opt/vmware/hms/bin/hms-configtool -cmd reconfig -property
hms-embedded-hbr=false
  2. Restart the HMS service.
    # service hms restart

Results

You can now unregister the embedded vSphere Replication server from the vSphere Replication user interface.

What to do next

Rebooting vSphere Replication does not automatically register the embedded server. To restore the default behavior to automatically register the embedded vSphere Replication server, type 
# /opt/vmware/hms/bin/hms-configtool -cmd reconfig -property
hms-embedded-hbr=true
# service hms restart
