Cascaded FICON fabric
NOTE
You must have FICON Management privileges to configure a fabric for cascaded FICON.
NOTE
If HIF mode is not enabled and the FMS mode is deployed, then the fabric will set the HIF key.
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.
NOTE
You must enable FMS mode for logical fabrics running Fabric OS 7.3.0 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 mode 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 7.1 or later, you can enable FMS mode when logical
switches are configured to allow XISL use.
