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. The CHPID Mapping Tool updates the IOCP input and assigns PCHIDs to the CHPIDs.

You can use the option Build and manage IBM zSystem cluster IOCDSs, IPL attributes, and dynamic I/O changes to update the selected I/O configuration data set for one or more processors.
