Re: INPUT/OUTPUT CONFIGURATION
You can just go to HMC and do a PCHID reassign from bad one to a good one in same or in another Escon Card.

Re: INPUT/OUTPUT CONFIGURATION
The HMC or SE has the ability to do this, or used to so a ESCON port could be sparred over to another port. That way you did not have to code it in the IOCP.

Re: INPUT/OUTPUT CONFIGURATION
Reassigning the selected channel path identifier (CHPID) to another partition could not be completed. The selected CHPID is not reconfigurable. Select a reconfigurable CHPID and try the operation again.

I'm currently looking in the System z Input/Output Configuration Program User's Guide for ICP IOCP but I'm not sure what to look for. IOCP is complaining because you are trying to assign more than 8 paths to a Control Unit. (See Machine Limits appendix.) The service rep will use PCHID/CHPID reassignment on the SE to logically move the CHPID associated with the failing port (PCHID) to a good port on the *same card*. Check out the IBM System z Connectivity Handbook (redbook). It has an extensive discussion on ESCON channel sparing.
