Cascaded FICON fabric

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:
•
•
•
•
•
•
476
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.
