Brocade FICON Administrator’s Guide (Supporting Fabric OS v7.3.0) - Manual (Page 58)

On a Brocade DCX and DCX-4S Backbones, when Virtual Fabrics is not enabled or addressing Mode
1 is not used, you must disable physical ports associated with addresses 0xFE and 0xFF (if ports were
assigned by default) before enabling FMS mode. Note that physical ports associated with 0xFE and
0xFF may be different in logical switches using Mode 1 addressing. Disable these addresses manually
if there is an active device attached. If an active device is not attached to the ports, they will be
disabled automatically when you enable FMS mode.
You can only disable ports if there is a card present in the slot.
If FMS mode is enabled in a logical switch with Mode 2 addressing, the physical ports with addresses
0xFE and 0xFF are essentially wasted and may be used better elsewhere. This is the same for a
switch with Mode 1 addressing where all available addresses are used, and thus no addresses are
available for binding to these ports. On logical switches with Mode 1 addressing, such ports may be
reclaimed for external connections by binding a new address to the port, if unused addresses are
available.
Ports that are disabled for having addresses "FE or "FF" when FMS mode is enabled are not eligible
for port swapping.
Configuring FICON CUP in Virtual Fabrics
For details on FICON and FICON CUP in Virtual Fabrics, refer to FICON and FICON CUP in Virtual
Fabrics on page 43.
Determining physical port assignment
The following steps help you locate the physical port from CUP_PortAddress.
1. Connect to the switch and log in using an account assigned to the admin role.
2. Set the context to the appropriate logical switch.
3. Enter the switchShow command.
4. Look for the PID in the Address column.
5. Read across to the Slot and Port columns to find the physical port number.
For more information and example output from the switchShow command, refer to the Fabric OS
Command Reference.
FMS mode and FICON CUP
Enabling FICON Management Server (FMS) mode in a Fabric OS environment allows the switch to
behave within the context of the FICON architecture and creates a FICON director. The FMS mode
setting can be changed whether the switch is disabled or enabled. If FMS mode is changed while the
switch is enabled, a device reset is performed for the control device and an RSCN is generated with
PID 0xDDFE00, where 0xDD is the domain ID of the switch.
The following are required on the switch to enable FMS mode:
• For Fabric OS 7.0 and later, a FICON CUP license.
• For Fabric OS 7.3 and later, High-Integrity Fabric (HIF) mode must be enabled.
Changing FMS mode from disabled to enabled triggers the following events:
