Cascaded FICON fabric
NOTE
You must have FICON Management privileges to configure a fabric for cascaded FICON.
The Management application enables you to easily configure a fabric for cascaded FICON. Note
that configuring a fabric for cascaded FICON may be disruptive to current I/O operations in the
fabric, as it needs to disable and enable the switches in the fabric.
FICON configuration performs the following operations on the selected fabric:
• Turns on the insistent domain ID flag (IDID) on all switches.
• Sets High Integrity Fabric Configuration (HIFC) on the seed switch.
- Fabric-wide consistency policy (FWCP) is configured to include SCC in strict mode.
- SCC policy is created or modified to limit connectivity to only the switches in the selected
fabric.
• Enables port-based routing on all switches.
• Enables In-Order Delivery (IOD) on all switches.
• Enables Dynamic Load Sharing (DLS) based on user selection and the firmware level.
NOTE
To enable DLS, all switches in a fabric should have equal Fabric OS levels.
• (Optional) Turns on FICON Management Server (FMS) mode on all switches.
- If switches are running Fabric OS 7.0 and later, FMS will not be enabled unless the
switches have an active CUP license.
- If switches are running Fabric OS earlier than 7.0 and not have a CUP license, after
successful configuration, you can access the Port Connectivity (Allow/Prohibit) matrix, but
the host system cannot communicate with the FICON Management Server unless you
install a CUP license. If a CUP license is later installed on these switches, then FMS mode
must be re-enabled on these switches.
Configuring a cascaded FICON fabric
NOTE
If you receive a 'FICON not supported on switch' error, refer to FICON troubleshooting for a list of
possible causes.
The FICON wizard automatically creates high integrity fabric configuration settings that support a
cascaded FICON fabric.
1. Select Configure > FICON > Configure Fabric.
The Configure Cascaded FICON Fabric screen of the FICON Configuration dialog displays.
2. Use the Fabric drop-down selector to select the fabric you want to configure.
NOTE
(Fabric OS switches only) All switches in a fabric must be running Fabric OS version 5.3 or later.
If a Fabric OS version earlier than version 5.3 is present in the topology, the fabric is not listed.
