ICP225I CONTROL UNIT xxxx ALREADY DEFINED ON THE CHANNEL PATH ASSOCIATED WITH CHPID yy IN CSS z

Explanation

A CNC, CTC, FCV, or FC channel path (TYPE keyword) cannot attach to more than one control unit unless it attaches to an ESCON or FICON® Director (SWITCH keyword) or unless the control units have unique logical addresses (CUADD keyword). An IQD, OSD, OSM, or OSX channel path (TYPE keyword) cannot have more than one control unit defined to it unless the control units have unique logical addresses (CUADD keyword). Control unit xxxx does not have a logical address and channel path yy in CSS z does not attach to a director.

System action

IOCP continues to validate and check the syntax of the remaining statements. However, it does not generate an IOCDS and it does not produce configuration reports.

Programmer response

Do one of the following:
  • Attach the channel path to an ESCON or FICON Director
  • If you are defining a control unit that supports logical addressing, specify the unique logical addresses that your control unit supports by using the CUADD keyword.
    Note: Not all ESCON and FICON control units support logical addressing.
  • If you must define more than 256 devices for an IQD channel path or 254 devices for an OSD, OSM, or OSX channel path, multiple control units must be defined. Specify a unique logical address for each control unit using the CUADD keyword.
