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 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 4 Gbit/sec platform switches.
• Enables In-Order Delivery (IOD) on all switches.
• Disables Dynamic Load Sharing (DLS) on all switches.
• (Optional) Turns on FICON Management Server (FMS) mode on all switches.
If some switches already have FMS mode enabled, it is re-enabled. If you select FMS mode to
be enabled on all switches and if some of the switches do not have a CUP license, then after
successful configuration, you can access the Port Connectivity (PDCM) 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.
If there are any M-EOS switches in the selected fabric, configuration enables Enterprise Fabric
Mode (EFM) on those switches.
