Cascaded FICON setup

• Turns on the insistent domain ID flag (IDID) on all switches.
• Enables port-based routing on 4 Gbps platform switches.
• Disables Dynamic Load Sharing (DLS) on all switches.
• Enables In-Order Delivery (IOD) 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.
• (Optional) Turns on FICON Management Server (FMS) mode on all switches. If some switches
already have FMS mode enabled, it is re-enabled.
• (Optional) Sets the IOD Delay Time on for switch pairs you have selected.
Fabric Manager performs an RBAC check on all switches in the fabric for the above operations,
except for setting HIFC, for which Fabric Manager performs an RBAC check on the seed switch only.
If the RBAC check fails for any operation on any switch, an error message displays listing the errors
for each failed operation.
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.
You may choose to change the IOD delay times for certain switch pairs depending on the number of
hops between the switches. You can use a larger delay for longer paths and smaller delays for
shorter paths. The default delay is 500 milliseconds. In addition to configuring the IOD delay in the
following procedure, you can also launch the IOD Delay wizard from the Task menu or the right click
menu for a fabric.
Configuring a fabric for cascaded FICON
1. Select Tasks > Cascaded FICON Setup > Configure a fabric for cascaded FICON setup.
If none of the discovered fabrics meet the requirements for cascaded FICON (all switches must
be running Fabric OS v5.2.0 or later and fabric must not be a secure fabric), then an
informational message displays.
Otherwise, the FICON configuration utility shown in Figure 171 on page 271 displays.
