This chapter describes how to define FICON switches and FICON Channel path IDs (CHPIDs), and connect them to a DASD Control Unit. It includes a list of these potential configuration items and a short description on how to do each of them using HCD. 

Note: Not all of the following configuration items are necessarily required for your installation. In addition, the examples presented are not exhaustive. 

This chapter shows only the definition process. If you want a deeper understanding of how to use HCD and FICON, see these resources:
