vSphere Replication Service Fails with Unresolved Host Error

If the address of vCenter Server is not set to a fully qualified domain name (FQDN) or to a literal address, the vSphere Replication service can stop unexpectedly or fail to start after a reboot.

Problem

The vSphere Replication service stops running or does not start after a reboot. The error unable to resolve host: non-fully-qualified-name appears in the vSphere Replication logs.

Solution

1. In the vSphere Web Client, select the vCenter Server instance and click Manage > Settings > Advanced Settings to check that the VirtualCenter.FQDN key is set to either a fully qualified domain name or to a literal address.
2. Use a supported browser to log in to the vSphere Replication VAMI.

   The URL for the VAMI is https://vr-appliance-address:5480.

3. Review and confirm the browser security exception, if applicable, to proceed to the login page.
4. Type the root user name and password for the appliance.

   You configured the root password during the OVF deployment of the vSphere Replication appliance.

5. Enter the same FQDN or literal address for vCenter Server as you set for the VirtualCenter.FQDN key.
6. Click Save and Restart Service to apply the changes.
