    @swill as you can see the diff here, we need the latter block:
    
    ```
                    String diskController = getLegacyVmDataDiskController();
                    if (controllerInfo != null &&
                            !Strings.isNullOrEmpty(controllerInfo.get(VmDetailConstants.DATA_DISK_CONTROLLER)))
{
                        diskController = controllerInfo.get(VmDetailConstants.DATA_DISK_CONTROLLER);
    ```
