If you use HCM and HCD, develop the configuration using HCM and HCD and store the information in an I/O Definition File (IODF). Otherwise, develop the IOCP statements necessary to define your configuration and use the level of the ICP IOCP program that supports the new processor to verify the input statements. You do not need to initially assign PCHID values to the channel paths in your configuration. You can use the CHPID Mapping Tool, available from Resource Link® at http://www.ibm.com/support/resourcelink, to aid you in assigning PCHIDs to CHPIDs. HCM and HCD users must build an IOCP input data set from a validated work IODF and use this as input to the CHPID Mapping Tool. The CHPID Mapping Tool updates the IOCP input and assigns PCHIDs to the CHPIDs.

Note: An IOCP input file that was created by HCM and HCD without PCHIDs must be migrated back into a HCM and HCD IODF after PCHID numbers have been added to the file by the CHPID Mapping Tool.

Inform the install team that plans are in place to use the Build remote IOCDS option in HCD to write the IOCDS. When you install a new processor that does not contain an IOCDS, you can use HCD to build an IOCP input deck, transfer the data set to the USB flash memory drive, and run the processor's IOCP stand-alone program.
