ICP354I **CAUTION** MINIMUM NUMBER OF DEVICES HAVE NOT BEEN DEFINED FOR [CHPID xx IN CSS y | THE CHANNEL PATHS IN CSS x IN CONTROL UNIT yyyy]

Explanation

You did not define the minimum number of devices recommended for a coupling facility channel path or control unit. CFP, CBP, and ICP channel paths (TYPE keyword) assigned to a control unit must have a minimum of seven devices each on most CPCs but on some CPCs, ICP channel paths should have a minimum of eight devices each. CIB channel paths assigned to a control unit must have a minimum of seven devices each which is what IOCP tests but some adapters have a minimum of 32 devices.CL5 and CL6 channel paths assigned to a control unit must have a minimum of eight devices each, but IBM recommends that 32 be defined. CS5 channel paths assigned to a control unit must have a minimum of eight devices each. CFS and CBS channel paths must have a minimum of two devices each. If the message is for channel path xx in CSS y, the channel path is a CFS or CBS channel path and does not have a control unit. If the message is for the channel paths in CSS x in control unit yyyy, the minimum number of devices necessary to fully support the channel paths in CSS x in the control unit were not defined. See Coupling facility channels section to determine the correct number of devices to define for your hardware type.

System action

IOCP prints this caution message and continues processing.

Programmer response

Define the minimum number of devices recommended for the channel path type for either the channel path or the CSS in the control unit.
