Doug, an OSA-card can be used in non-QDIO mode (OSE) or in QDIO-mode (OSD). Your IOCDS-definition defines the type of your OSA-Express channel to be OSE or OSD. If lscss displays a CU-Type 1731/01, your OSA-Express channel is defined as OSD. In Linux the lcs-driver is responsible for OSE-type channels and the qeth-driver is responsible for OSD-type channels. For OSD-type devices a subchannel-triple is necessary to create a qeth-device, for instance
