Mode register bit settings
Configuration files downloaded with Active=Saved mode disabled
The contents of existing files saved on the switch, which are also present in the [FICU SAVED FILES]
section, are overwritten.
The files in the [FICU SAVED FILES] section of the configuration file, which are not currently on the
switch, are saved on the switch.
The IPL is replaced because Active=Saved mode is disabled.
Sample IOCP configuration file
The channel subsystem controls communication between a configured channel, the control unit,
and the device. The I/O Configuration Data Set (IOCDS) defines the channels, control units, and
devices to the designated logical partitions (LPARs) within the server; this is generated using the
Input/Output Configuration Program (IOCP). The IOCP statements are typically built using the
hardware configuration definition (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 switch 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
switches 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 switch's range.
The switch ID must 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.
Brocade recommends that the switch ID (in IOCP or HCD) be set to the same value as the domain
ID of the FICON switch, which is defined to the switch 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 switch regardless of vendor or platform. All Brocade switches require UNIT=2032 for the
CUP definition. All Domain IDs are specified in hex values in the IOCP (and not in decimal values).
