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 this involves disabling and enabling 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 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 265 on page 759.
