In the above section check that the CUADD is EQ to the Lpar Number in the HCD Definition. > > * ESA11 <-> IFL > > IODEVICE ADDRESS=(0440,32),CUNUMBR=(0403),UNITADD=00, X > UNIT=SCTC,PART=(ESA11,ESA12,IFL) > IODEVICE ADDRESS=(0500,32),CUNUMBR=(0501),UNITADD=00, X > UNIT=SCTC,PART=(ESA11,ESA12,IFL) > In the above section the Destination LPAR should not be in the candidate list. EG if you are using 448 and 449 to communicate **TO** LPAR IFL then do not specify IFL in the Partition list. You can then have all lpars that wish to communicate **TO** that LAPR use the same addresses.
