IOCDS Gen Requirements
Each BSC 3270 device (display and printer) that is to be supported by the FEP-4600 over
a BSC line requires that a single subchannel address be assigned, to the host LPAR that
owns the resource. A single CNTLUNIT macro is used to define the collection of devices
attached to a single BSC cluster controller. An example gen using an ESCON CHPID
might appear as follows:
RESOURCE PARTITION=((PROD1,1),(TEST,3))
CHPID PATH=(1E),TYPE=CNC,SWITCH=01,SHARED
CNTLUNIT CUNUMBR=1E00,PATH=1E,UNITADD=((00,32)),UNIT=NOCHECK,LINK=C5
IODEVICE CUNUMBR=1E00,ADDRESS=(1700,30)UNIT=2701,UNITADD=00,PARTITION=(PROD1)
IODEVICE CUNUMBR=1E00,ADDRESS=(171E,2)UNIT=2701,UNITADD=1E,PARTITION=(PROD1)
Note that you may require multiple IODEVICE macros to describe the attached devices,
since there are a number of device specific UNIT types.
The same type of definition using a FICON CHPID would look similar:
RESOURCE PARTITION=((PROD1,1),(TEST,3))
CHPID PATH=(27),TYPE=FC,SWITCH=02,SHARED
CNTLUNIT CUNUMBR=1E00,PATH=27,UNITADD=((00,32)),UNIT=NOCHECK,LINK=C7
IODEVICE CUNUMBR=1E00,ADDRESS=(1700,30)UNIT=2701,UNITADD=00,PARTITION=(PROD1)
IODEVICE CUNUMBR=1E00,ADDRESS=(171E,2)UNIT=2701,UNITADD=1E,PARTITION=(PROD1)
On a processor that supports Logical Subsystems (such as the z990), the definitions will
look slightly different. Here is the same set of definitions as would be seen for the z990
(over ESCON).
RESOURCE PARTITION=(CSS(0),(PROD1,1),(TEST,3))
CHPID PATH=(CSS(0),1E),TYPE=CNC,SWITCH=01,SHARED,PCHID=150
CNTLUNIT CUNUMBR=1E00,PATH=(CSS(0),1E),UNITADD=((00,1)),UNIT=NOCHECK,LINK=(CSS(0),C5)
IODEVICE CUNUMBR=1E00,ADDRESS=(1700,1)UNIT=2701,UNITADD=00,PARTITION=(CSS(0),PROD1)
IODEVICE CUNUMBR=1E00,ADDRESS=(171E,1)UNIT=2701,UNITADD=1E,PARTITION=(CSS(0),PROD1)
