ICP353I IOCP HAS GENERATED xxxxx CONTROL UNIT HEADERS FOR CSS y WHICH EXCEEDS THE MAXIMUM NUMBER ALLOWED
Explanation
IOCP tried to generate more control unit headers (CUHs) in a CSS than your CPC supports. Review the limits and rules for the generation of CUHs for your CPC. See Machine limits to verify what your CPC supports.
System action
IOCP does not complete the generation of an IOCDS and does not produce configuration reports.
Programmer response
Ensure that the configuration does not exceed the maximum number of CUHs for a CSS. You might need to reduce the number of physical control units or have more control units share devices.
