Configuring FICON CUP
To set up FICON CUP, use the following procedure.
1.
Connect to the switch and log in using an account assigned to the admin role.
2.
Verify that the switch or backbone has been set up according to the instructions in
on page 37 and, if in a cascaded topology,
on page 41.
3.
For switches with at least 256 ports installed, use the portDisable command to disable ports 0xFE
and 0xFF. Refer to
on page 55 for more information.
4.
Enter the ficonCupShow fmsmodefmsmode command to verify if FMS mode 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 may 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.
7.
Be sure that the switch meets requirements for a high-integrity fabric, and then enable High-
Integrity Fabric (HIF) mode using the configure command. For details, refer to
on page 33.
NOTE
You must enable HIF mode to enable FMS mode.
8.
Enter the ficonCupSet modereg command to set the mode register bits. Refer to
on page 60 for more information.
9.
Verify with the systems programmer that the CUP ports are defined properly.
FICON ports are defined as part of the sysgen process. The z/OS systems programmer can verify
if the CUP ports are defined properly.
Disabling ports 0xFE and 0xFF
Addresses 0xFE and 0xFF are not available for external connections, so they must be disabled to
configure FICON CUP. Note that in logical switches or in cases where port address binding or port
swapping has occurred, addresses 0xFE and 0xFF are not necessarily tied to specific physical ports,
such as 254 and 255. 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 cable connected to either of them to another free port.
You must manually disable ports associated with 0xFE and 0xFF to enable FMS mode only if there is
an active device connected to these ports. Otherwise, if physical ports have been assigned these
addresses by default prior to enabling FMS mode, they will be automatically disabled when FMS mode
is enabled.
