12.2 FICON CHPIDs, switches, and DASD control units 12.2.1 Defining FICON CHPIDs and connecting them to a FICON switch This section describes defining FICON CHPIDs, and then connecting them to FICON  switches and a DASD control unit. A new FICON CHPID includes the following considerations: GLYPH<SM590000> Channel path ID (CHPID). GLYPH<SM590000> Channel ID (CHID). GLYPH<SM590000> Channel path type. GLYPH<SM590000> Operational mode. GLYPH<SM590000> Description. GLYPH<SM590000> Dynamic entry switch ID. GLYPH<SM590000> Entry switch ID. GLYPH<SM590000> Entry port. GLYPH<SM590000> Partition access list. GLYPH<SM590000> For performance and redundancy, how many CHPIDs are required to connect to the  FICON Switch, and then to one or more Control Units? GLYPH<SM590000> For performance and redundancy, how many I/O cards of that feature are installed in the  processor and to what PCIe ports and to which CPC drawer do the I/O cards connect (see  the PCHID/CHID report for a list of installed hardware)? GLYPH<SM590000> After a CHPID is defined, it can then be: – Added to a predefined partition in that CSS – Connected to a FICON switch – Connected to a Control Unit 1. From the main HCD panel, select option 1.3. Processors 2. Enter  s  next to the Processor that you want to add a CHPID to, and press Enter. 3. Enter  s  next to the CSS ID that you want to add a CHPID to, and press Enter. 5. Complete the following updates and press Enter: 4. In the command line, enter  add  (see Figure 12-3 on page 279) to add a CHPID. – Channel path ID  to  14 – Channel ID  to  114 – Operational mode  to SHR – Channel path type  to  FC – Description  to whatever description that you want – Dynamic entry switch ID  to  41 – Entry switch ID  to  41  (optional, but preferred) – Entry port  to  10  (optional, but preferred) To define a new FICON CHPID, connect to a FICON switch, and provide access to a partition,  complete the following steps: 278  IBM z14 Model ZR1 Configuration Setup
