Reissue the command, and specify a valid parameter value. If this is for the ELEMENT parameter on DEFINE DRIVE with AUTODETECT, this message can be issued because the library doesn't support the ability to determine the element number dynamically. In this case, supply the actual element number instead of using AUTODETECT for the ELEMENT parameter. If this is for the SCALECAPACITY parameter on a 3592 device class, verify that this device class has the attribute WORM=NO as WORM and SCALECAPACITY are not compatible.
