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
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
