Cascaded FICON 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 the fabric must be 8 Gbps or faster and running Fabric OS 6.4 or

later.

• (Optional) Turns on FICON Management Server (FMS) mode on all switches.

Consider the following information when enabling FMS mode.

- 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 version 7.0 and do 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.

- For logical fabrics running Fabric OS v7.1 or later, you can enable FMS mode when logical

switches are configured to allow XISL use.

Configuring a cascaded FICON fabric

The FICON wizard automatically creates HIFC settings that support a cascaded FICON fabric.

1. Select Configure > FICON > Configure Fabric or right-click a fabric in the product tree and

select FICON > Configure Fabric.

The Configure Cascaded FICON Fabric screen of the FICON Configuration dialog displays, as

shown in Figure 261 on page 711.
