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.


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.


  1. In the vSphere Client, select Administration > vCenter Server Settings > Advanced Settings and check that the VirtualCenter.FQDN key is set to either a fully qualified domain name or to a literal address.
  2. Connect to the VAMI of the vSphere Replication appliance in a Web browser.

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

    You can also access the VAMI by clicking Configure VR Appliance in the Summary tab in the vSphere Replication view of the Site Recovery Manager interface.

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