Control Unit defined passes HCD. Prior to an IPL EEFE and EEFF were "unbound". After systems were IPL'd, received command reject errors on devices EEFE and EEFF. Both devices were suppose to be unavailable.

IODFs will be attached.

    This item is a valid requirement but unlikely to be given high enough priority to be placed into the product plan

    We understand the requirement and had some discussions with our L2 team in POK with the following outcome:

    We agree that this is a valid requirent for HCD.
    To avoid the customer situation a possible rule and requirement would be:

    - If a user defines different control units with the same CUADD and SERNO,
    - and the control units have different paths to the same CEC
    - and there are alias defined to one of the control units

    then HCD shows an error message (mainly this will be for scenarios like connect control unit to processor, change cuadd of control unit, connect devices to cu, change serial number of CU)

    It would be the responsibility of the customer to work with a serial number (we should recommend this anyhow).
    And the check would probably make sense for all control unit types with alias.
