IOCDS Gen Requirements when VTAM XCA Major Nodes are Used
A single subchannel is required for each network adapter in the FEP-4600 that will be
used for XCA communications. Each XCA definition will support up to 255 concurrent
PU connections. Multiple XCA definitions to either the same adapter or to different
adapters from the same LPAR can use a consecutive address range of subchannels. A unit
type of 3172 or SCTC is typically used to define the FEP-4600 for an XCA definition.
The following definition could be used to support up to 1020 DSPUs to the hosting
LPAR over ESCON.
RESOURCE PARTITION=((PROD1,1),(TEST,3))
CHPID PATH=(1F),TYPE=CNC,SWITCH=01,SHARED
CNTLUNIT CUNUMBR=1400,PATH=1F,UNITADD=((00,4)),UNIT=SCTC,LINK=C5
IODEVICE CUNUMBR=1400,ADDRESS=(640,4)UNIT=SCTC,UNITADD=00,PARTITION=(PROD1)
When FICON is used the CHPID TYPE is different as well as the CNTLUNIT UNIT
type.
