Coupling facility peer channels (TYPE=CFP, TYPE=CBP, TYPE=ICP, TYPE=CIB, TYPE=CL5, or TYPE=CS5)
You can configure a CFP, CBP, ICP, CIB, CL5, and CS5 channel path as:
Coupling facility peer channel paths can be shared by many ESA LPs and only one coupling facility LP at the same time. CFP, CBP, CIB, CL5, and CS5 channel paths are used when connecting two CPCs that support coupling facility peer channel paths. ICP channel paths are used when connecting coupling facility and ESA LPs on the same CPC. CFP channel paths are defined for ISC-3 links. CBP channel paths are defined for ICB-3 and ICB-4 links. CIB channel paths are defined for InfiniBand links. CS5 channel paths are defined for Integrated Coupling Adapter links. CL5 channel paths are defined for Coupling Express LR adapter links. Each CFP, CBP, ICP, CIB, CL5, and CS5 channel path assigned to a coupling facility control unit should have seven, eight, or 32 devices defined.
