Configuring FICON CUP 3 Configuring FICON CUP To set up FICON CUP, use the following procedure and be sure to perform the steps in the order indicated. 1. Connect to the switch and log in using an account assigned to the admin role. 2. Verify that the switch or director has been set up according to the instructions in "Configuring switched point-to-point FICON" on page 16 and if in a cascaded topology, "Configuring Cascaded FICON" on page 20. 3. For directors with at least 256 ports installed, use the portDisable command to disable ports 254 and 255. Refer to "Persistently enabling and disabling ports for CUP" on page 35 for more information and detailed instructions. Ports 254 and 255 are not supported in a CUP environment. After FMS mode has been successfully enabled, these two ports remain disabled and cannot be used either as an F_Port or an E_Port. Because these ports are not available after enabling FMS mode, you should first move any fiber connected to either of them to another free port. Ports 254 and 255 are defined on the enterprise-class platforms in slot/port notation as follows: • On a Brocade 48000 disable 10/30 and 10/31. • On a Brocade DCX Backbone disable 12/30 and 12/31 when Virtual Fabrics is not enabled or zero-based addressing is not used. These physical locations may be different in logical switches using zero-based addressing. The recommended best practice for a DCX is to create a logical switch that does not include ports assigned with addresses 0xFE and 0xFF. • On a Brocade DCX-4S disable the corresponding ports for addresses 0xFE and 0xFF when these ports are assigned to a logical switch. The recommended best practice for a logical switch in a DCX-4S is to not assign any ports with addresses 0xFE and 0xFF. NOTE You can only disable these ports if there is a card present in the slot. 4. Enter the ficonCupShow fmsmode command to verify if fmsmode is disabled. 5. Take the appropriate action based on whether FMS mode is enabled or disabled: • If FMS mode is disabled, proceed to step 6. • If FMS mode is enabled, disable it using the ficonCupSet fmsmode disable command. ATTENTION If FMS mode is already enabled, disabling it might be disruptive to operations because ports that were previously prohibited from communicating will be allowed to do so because prohibits are no longer enforced. You must disable FMS mode to continue setting up CUP. 6. Install a CUP license on the switch. For more information on installing a license, refer to the Fabric OS Administrator's Guide.

Configuring FICON CUP
To set up FICON CUP, use the following procedure and be sure to perform the steps in the order
indicated.
1.
Connect to the switch and log in using an account assigned to the admin role.
2.
Verify that the switch or director has been set up according to the instructions in
“Configuring
switched point-to-point FICON”
on page 16 and if in a cascaded topology,
“Configuring
Cascaded FICON”
on page 20.
3.
For directors with at least 256 ports installed, use the
portDisable
command to disable ports
254 and 255. Refer to
“Persistently enabling and disabling ports for CUP”
on page 35 for more
information and detailed instructions.
Ports 254 and 255 are not supported in a CUP environment. After FMS mode has been
successfully enabled, these two ports remain disabled and cannot be used either as an F_Port
or an E_Port. Because these ports are not available after enabling FMS mode, you should first
move any fiber connected to either of them to another free port. Ports 254 and 255 are
defined on the enterprise-class platforms in slot/port notation as follows:
•
On a Brocade 48000 disable 10/30 and 10/31.
•
On a Brocade DCX Backbone disable 12/30 and 12/31 when Virtual Fabrics is not
enabled or zero-based addressing is not used. These physical locations may be different in
logical switches using zero-based addressing. The recommended best practice for a DCX is
to create a logical switch that does not include ports assigned with addresses 0xFE and
0xFF.
•
On a Brocade DCX-4S disable the corresponding ports for addresses 0xFE and 0xFF when
these ports are assigned to a logical switch. The recommended best practice for a logical
switch in a DCX-4S is to not assign any ports with addresses 0xFE and 0xFF.
NOTE
You can only disable these ports if there is a card present in the slot.
4.
Enter the
ficonCupShow fmsmode
command to verify if fmsmode is disabled.
5.
Take the appropriate action based on whether FMS mode is enabled or disabled:
•
If FMS mode is disabled, proceed to
step 6
.
•
If FMS mode is enabled, disable it using the
ficonCupSet fmsmode disable
command.
ATTENTION
If FMS mode is already enabled, disabling it might be disruptive to operations because ports
that were previously prohibited from communicating will be allowed to do so because prohibits
are no longer enforced.
You must disable FMS mode to continue setting up CUP.
6.
Install a CUP license on the switch. For more information on installing a license, refer to the
Fabric OS Administrator’s Guide
