ICP239I TOO MANY CHPIDS ASSIGNED TO CONTROL UNIT

Explanation

A control unit attached to FCP, IQD, OSC, OSD, OSE, OSH, OSM, OSN, or OSX channel paths or an ESCON CTC or FICON® CTC control unit can have only one channel path assigned to it in each CSS. IOCP defines an ESCON CTC control unit as either of the following:
  • A control unit that attaches to only TYPE=CTC channel paths
  • A control unit that attaches to only TYPE=CNC or TYPE= FCV channel paths and has UNIT=SCTC coded.

IOCP defines a FICON CTC control unit as a control unit that attaches to only TYPE=FC channel paths and has UNIT=FCTC coded.

System action

IOCP continues to validate and check the syntax of the remaining statements. However, it does not generate an IOCDS and it does not produce configuration reports.

Programmer response

Ensure that the control unit only attaches to one channel path per CSS if the control unit is an ESCON CTC or FICON CTC control unit or the control unit attaches to FCP, IQD, OSC, OSD, OSE, OSH, OSM, OSN, or OSX channel paths.
