Example 1:
In this example the LPARs 1 (PRODA) and 3 (PRODC) are interconnected with a CTC
connection. And although EMIF is present and used to share channels for other
applications, CHPID 1F must be unshared and only LPAR3 has a direct connection to the
FEP-4600. A second CHPID would be required into the ESCON switch to allow direct
connection of LPAR1 to the FEP-4600.
RESOURCE PARTITION=((PRODA,1),(PRODC,3))
CHPID PATH=(1F),TYPE=CNC,SWITCH=03
CNTLUNIT CUNUMBR=1F00,PATH=1F,UNITADD=((00,1)),UNIT=SCTC,CUADD=0,LINK=C5
IODEVICE CUNUMBR=1F00,ADDRESS=(680,1),UNIT=SCTC,UNITADD=00,PARTITION=(PRODC)
On a processor that supports Logical Subsystems (such as the z990 or z9), the definitions
will look slightly different. Here is the same set of definitions as would be seen for the
z990 if these LPARs are in CSS0. If connections from LPARs in two different CSS’s are
needed then you must have two separate ESCON channels coming from the CPU, one for
each CSS.
RESOURCE PARTITION=(CSS(0),(PRODA,1),(PRODC,3))
CHPID PATH=(CSS(0),1F),TYPE=CNC,SWITCH=03
CNTLUNIT CUNUMBR=1F00,PATH=(CSS(0),1F),UNITADD=((00,1)),UNIT=SCTC,LINK=(CSS(0),C5)
IODEVICE CUNUMBR=1F00,ADDRESS=(680,1),UNIT=SCTC,UNITADD=00,PARTITION=(CSS(0),PRODC)
The same type of definition for a FICON CHPID may look like this:
RESOURCE PARTITION=(CSS(0),(PRODA,1),(PRODC,3))
CHPID PATH=(CSS(0),3D),TYPE=FC,SWITCH=03
CNTLUNIT CUNUMBR=1F00,PATH=(CSS(0),3D),UNITADD=((00,1)),UNIT=FCTC,LINK=(CSS(0),C5)
IODEVICE CUNUMBR=1F00,ADDRESS=(680,1),UNIT=FCTC,UNITADD=00,PARTITION=(CSS(0),PRODC)
