Configuring FICON CUP in Virtual Fabrics

You can configure up to two CUP switches as logical switches in a Virtual Fabric-enabled platform
for FICON FMS mode. A base switch cannot be configured as a FICON switch.
FICON CUP-enabled logical switches are not supported as logical fabric-capable logical switches, so
FICON logical switches will not participate in the use of extended ISLs on the base switch.
You cannot have 48-or 64-port blades in the default logical switch with FMS mode enabled. Also,
you cannot have chassis port numbers greater than 255 in a logical switch with FMS mode
enabled.
If addresses 0xFE or 0XFF have been assigned to external ports, those ports must be disabled.
When FMS mode is enabled and Virtual Fabrics mode is disabled, the ports on a 48-port blade are
not supported to connect to either FICON or FCP (open system) devices.
When FMS mode is enabled and Virtual Fabrics mode is enabled, the ports on a 48-port blade are
not supported to connect to either FICON or FCP (open system) devices. This is enforced starting
with Fabric OS v6.3.0 and the ports on a 48-port blade are explicitly disabled in the default switch.
This disabling occurs during an upgrade and insertion of the blade, where FOS detects these ports
in default switch.
When FMS mode is enabled and Virtual Fabrics mode is enabled, the ports on a 48-port blade are
supported in the non-default logical switch for both FICON open system devices. Address mode
limitations apply.
For FICON CUP, FMS mode is enabled on the logical switch and not the chassis. For example, in a
Virtual Fabric environment on the Brocade 5100 switch and the Brocade DCX and DCX-4S, one
would set CUP on each logical switch (currently limited to 2 logical switches per chassis).
Each logical switch has its own configuration data, such as the initial program load (IPL) file,
configuration data elements (PDCM, PIB, Port Address Names, Mode Register, Key Counter), and
CUP configuration files.
You can find the complete instructions for creating a logical switch in the Fabric OS Administrator's
Guide.

Take the appropriate action based on whether you have both B- and M-series switches in your
fabric:
•
If you do not have both series, proceed to
•
If you have both series, establish a secure E_Port between the supported platforms. For
B-series switches you can use SCC policies or EFCM v9.6. For M-Series switches use EFCM
or DCFM.
(FMS mode) on the switch.
FICON ports are defined as part of the sysgen process. The z/OS systems programmer can
verify if the CUP ports are defined properly.
