If your z10 BC was upgraded from a z114, then it might have a 2-port OSA-Express 2 1000BASE-T feature and if during the upgrade process additional features were added than it might also have OSA-Express 3 1000BASE-T 2-port or 4-port feature(s).
If the z10 BC was purchased as new, then it will be OSA-Express 3 1000BASE-T 2 port or 4 port features. For the 2-port feature, a single CHPID is defined as type OSC or OSE i.e. both ports have to be the same 'type'. For the 4-port feature, each pair of ports has a single CHPID defined i.e. 2 CHPIDs for the 4 ports. The 2 CHPIDs can be the same type or different i.e. both as OSC or OSE or one of each type. For each CHPID, the pair of ports have to be the same 'type'. BTW: There are some Redbooks which you might want to refer to: 1. OSA-Express Implementation Guide 2. OSA-Express Integrated Console Controller Implementation Guide (bit dated now) 3.

IOCP DECK is shown at the end of this mail. The OSA-ICC 3270 sessions are currently configured. OSE CHPID is defined, but nothing else is configured. I understand that OSE (Non-QDIO mode) requires UA and port, IP addr, mapping in OAT. Also, OAT and z/OS TCPIP PROFILE (DEVICE and LINK) setting will mapping. But, I don't understand how to assgin the OSA Physical ethernet ports. Qeustions: 1) Is the port set in OAT a OSA Physical port? 2) Can OSA-ICC 3270 sessions and OSE ports share a OSA Physical port? Should these have separate Physical ports? 3) Where is the physical port of the OSA-ICC session set? 4) OSE is assigned to ZOS2 LPAR in the PARTITION statement. But SHARED is also specified by CHPID. Are OSE devices also available in ZOS1 LPARs?
