ICP242I LINK ADDRESS xx ALREADY ESTABLISHED FOR CHPID yy IN CSS w BY CONTROL UNIT zzzz
Explanation
A CVC or CBY channel path (TYPE keyword) cannot have more than one link address (LINK keyword) unless it attaches to an ESCON Director (SWITCH keyword). Channel path yy in CSS w does not attach to a director and has been assigned link address xx by control unit zzzz. Link address xx differs from the link address that was specified on the CNTLUNIT statement that is in error.
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 link addresses for the channel path, make all link addresses identical, or attach the channel path to a director.
