Configuring a cascaded FICON fabric

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 is displayed

(Figure 179).

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 5.2 or later.

If a Fabric OS version earlier than version 5.2 is present in the topology, the fabric is not listed.

3. Select the FMS Mode check box to manage the fabric by a host-based management program

using FICON CUP protocol.

If you select FMS Mode, each switch is checked for a CUP license. Any switches that do not

have a CUP license are listed, with a reminder that a CUP license is necessary to communicate

with the fabric management server.

4. Select the DLS check box to enable dynamic load sharing (DLS) or Lossless DLS on all switches

in the fabric.

NOTE

DLS requires DLS support on the switch. Lossless DLS requires Lossless DLS support on the

switch.

DLS is only supported on the 40-port, 8 Gbps FC Switch, 80-port, 8 Gbps FC Switch, 384-port

Backbone Chassis, and 192-port Backbone Chassis.

Enabling DLS may result in dropped frames when paths fail over. It is recommended that you

set the preferred IOD Delay Time to minimize frame drops.
