When you deploy the vSphere Replication appliance, you get an error about unavailable features.

When you deploy the vSphere Replication, an error appears about unavailable features and vSphere Replication fails to deploy.

This error is typically the result of the vCenter Management Web service being paused or stopped.

Attempt to start the vCenter Management Web service. If the service fails to start, confirm that Tomcat is running on the server. If the server is installed, but not running, try starting the server. If attempting to start the Tomcat server does not resolve the problem, the issue might be occurring because the vCenter Server has the wrong version of Java installed.
