The following example shows the IOCP statement for Figure 2-15. This IOCP
coding example groups the input statements by logical partition. When coding IOCP,
view the I/O devices from a logical partition perspective.
CHPID PATH=(10),PARTITION=(A), . . .
CHPID PATH=(14),PARTITION=(A), . . .
CNTLUNIT CUNUMBR=0011,PATH=(10),UNITADD=(10), . . .
CNTLUNIT CUNUMBR=0012,PATH=(14),UNITADD=(0E), . . .
IODEVICE ADDRESS=(110),CUNUMBR=(0011), . . .
IODEVICE ADDRESS=(00E),CUNUMBR=(0012), . . .
CHPID PATH=(18),PARTITION=(B), . . .
CHPID PATH=(1C),PARTITION=(B), . . .
CNTLUNIT CUNUMBR=0013,PATH=(18),UNITADD=(10), . . .
CNTLUNIT CUNUMBR=0014,PATH=(1C),UNITADD=(0E), . . .
IODEVICE ADDRESS=(110),CUNUMBR=(0013), . . .
IODEVICE ADDRESS=(00E),CUNUMBR=(0014), . . .
CHPID PATH=(20),PARTITION=(C), . . .
CHPID PATH=(24),PARTITION=(C), . . .
CNTLUNIT CUNUMBR=0015,PATH=(20),UNITADD=(10), . . .
CNTLUNIT CUNUMBR=0016,PATH=(24),UNITADD=(0E), . . .
IODEVICE ADDRESS=(110),CUNUMBR=(0015), . . .
IODEVICE ADDRESS=(00E),CUNUMBR=(0016), . . .
CHPID PATH=(28),PARTITION=(D), . . .
CHPID PATH=(2C),PARTITION=(D), . . .
CNTLUNIT CUNUMBR=0017,PATH=(28),UNITADD=(10), . . .
CNTLUNIT CUNUMBR=0018,PATH=(2C),UNITADD=(0E), . . .
IODEVICE ADDRESS=(110),CUNUMBR=(0017), . . .
IODEVICE ADDRESS=(00E),CUNUMBR=(0018), . . .
Eight IODEVICE statements are used, one for each console and one for each
printer that has a duplicate device number. Device numbers 110 and 00E occur four
times each; however, they are not duplicated within a logical partition. When coding
an IOCP input file, remember that the unique device number rule applies for logical
partitions in an IOCDS.
