The I/O Configuration Dataset (IOCDS) defines the channels, control units, and devices to the designated logical partitions (LPARs) within the server; this is defined using the Input/Output Configuration Program (IOCP). The IOCP statements are typically built using the hardware configuration dialog (HCD). The interactive dialog is used to generate your Input/Output Definition File (IODF), invoke the IOCP program, and subsequently build your production IOCDS. Each FICON director in a fabric must have a unique domain ID and a unique switch ID. The switch ID used in the IOCP definitions can be any value between x'00' to x'FF'. The domain ID range for directors is hex x'01' to x'EF' or decimal 1 to 239. When defining the switch IDs in the IOCP definitions, ensure that you use values within the FICON director's range. The switch ID has to be assigned by the user and must be unique within the scope of the definitions (IOCP and HCD). The domain ID is assigned by the manufacturer and can be customized to a different value. It must be unique within the fabric. HP recommends that the switch ID (in IOCP or HCD) be set to the same value as the domain ID of the FICON director, which is defined to the FICON director at installation time. This simplifies the configuration and reduces confusion by having a common designation across all definitions. 510 FICON fabrics
