The physical ports are not exposed in the IOCP, just the CHPID, control unit,
and device numbers. The individual ports are selected in the communications
stack, for example, in z/OS they're in the VTAM TRLE.
So your IOCP would include things like:
CHPID PATH=(CSS(0),50),SHARED, *
PARTITION=((Y2KOLD,ZOSINST,ZOSPROD,ZOSSYQA,ZVMPROD,ZVMTE*
ST),(=)),PCHID=1A0,TYPE=OSD
CNTLUNIT CUNUMBR=0501,PATH=((CSS(0),50)),UNIT=OSA
IODEVICE ADDRESS=(500,015),CUNUMBR=(0501),UNIT=OSA
IODEVICE ADDRESS=50F,UNITADD=FE,CUNUMBR=(0501),UNIT=OSAD
and then in a VTAMLST member something like:
OSD0500 TRLE LNCTL=MPC,READ=0500,WRITE=0501,DATAPATH=(0502,0503), C
PORTNAME=PROD300A,PORTNUM=0,MPCLEVEL=QDIO
OSD0504 TRLE LNCTL=MPC,READ=0504,WRITE=0505,DATAPATH=(0506,0507), C
PORTNAME=PROD200A,PORTNUM=1,MPCLEVEL=QDIO
where the PORTNUM parameter selects the physical port.
Hope that helps.
