The TSM Server returned an empty network address or port number for 'datamover nodename'.
While querying the TSM Server for the Datamover network address and port number, the Server returned zero for one of the values.
The operation cannot continue without a valid Datamover network address and port number.
This is usually the result of a Datamover Node not being started. Log on to the Datamover host and start or restart the DSMCAD service and retry the TSM for Virtual Environments command again. If the problem persists, work with your TSM Server Administrator to inspect the TSM Server activity log to identify the issue.
