A Appendix A. Configuration example IOCP data sets This appendix includes examples of the following IOCP data sets: FICON FCTC using a single FC Channel Path (FICON FCTC loop) CIB coupling facility links used for STP only Special devices type 3390D in subchannel set 1 (duplicate device numbers). Because coupling facility links that are used for both CF and STP only is impossible between the CPCPKR1 and CPCPKR2 processors in the sample configuration, a third CPCPKR3 processor has been added for this example. Examples in this appendix show the following information: The IOCP data set for the CPCPKR1 processor, which is complete The IOCP data set for the CPCPKR1 processor, which does not include control units shared with the CPCPKR1 processor The IOCP data set for the CPCPKR3 processor, which includes coupling facility STP only links to the CPCPKR2 processor only © Copyright IBM Corp. 2010.
