Sample Iocp Configuration File For The San Switch 2/32, Core Switch 2/64, And San Director - HP A7533A - Brocade 4Gb SAN Switch Base User Manual

Sample IOCP configuration file for the SAN Switch 2/32, Core Switch 2/64, and SAN Director

The channel subsystem controls communication between a configured channel, the CU, and the device.
The IOCDS defines the channels, CUs, 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 box (HCD). The interactive dialog box 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 x00 to xFF. The domain ID range for directors is
hex x01 to xEF 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, see the IBM publication zSeries Input/Output Configuration Program User's Guide
for ICP IOCP (SB10-7037).
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 Domain IDs are specified in hex values in the
