ICP259I UNIT=STP INVALID FOR CONTROL UNITS ATTACHED TO INTERNALLY COUPLED CHPIDS

Explanation

You defined a control unit for Server Time Protocol (STP) to provide a timing network between CPCs. ICP and internally coupled CIB, CL5, and CS5 channel paths (TYPE keyword) cannot be used for STP. CIB, CL5, and CS5 channel paths have an internal coupling connection when their CSYSTEM keyword values (CHPID statement) match the local system name (LSYSTEM keyword on ID statement). See Server Time Protocol for more information about STP.

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

Remove all ICP channel paths from the control unit. Also, remove the CIB, CL5, or CS5 channel paths from the control unit or connect the CIB, CL5, and CS5 channel paths to the external CPC by changing all of their CSYSTEM keyword values.
