Sample Iocp Configuration File - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

Sample IOCP configuration file

The channel subsystem controls communication between a configured channel, the control unit, and the
device. The I/O Configuration Dataset (IOCDS) defines the channels, control units, and devices to the
designated logical partitions (LPARs) within the server; this is defined using the Input/Output Configuration
Program (IOCP). The IOCP statements are typically built using the hardware configuration dialog (HCD).
The interactive dialog is used to generate your Input/Output Definition File (IODF), invoke the IOCP
program, and subsequently build your production IOCDS.
Each FICON director in a fabric must have a unique domain ID and a unique switch ID. The switch ID used
in the IOCP definitions can be any value between x'00' to x'FF'. The domain ID range for directors is hex
x'01' to x'EF' or decimal 1 to 239. When defining the switch IDs in the IOCP definitions, ensure that you
use values within the FICON director's range.
The switch ID has to be assigned by the user and must be unique within the scope of the definitions (IOCP
and HCD).
The domain ID is assigned by the manufacturer and can be customized to a different value. It must be
unique within the fabric.
HP recommends that the switch ID (in IOCP or HCD) be set to the same value as the domain ID of the
FICON director, which is defined to the FICON director at installation time. This simplifies the configuration
and reduces confusion by having a common designation across all definitions.
For more information on switch numbering, refer to the IBM publication FICON® Implementation Guide
(SG24-6497-00).
In the following sample IOCP configuration file, the UNIT value for FICON CUP definitions is 2032 for
any FICON director regardless of vendor or platform. All HP switches require UNIT=2032 for the CUP
definition. All Domain IDs are specified in hex values in the IOCP (and not in decimal values); the Domain
IDs in the example are for demonstration purposes only.
