RSCNs on zSeries hosts

McDATA and CNT switches ship without any configured zoning. This unzoned configuration enables
the default zone on some McDATA switches. This configuration enables all ports in the switch with a
FC connection to communicate with each other and to receive registered state change notifications
about each other. You can set the zones.
Here are some recommendations:
If you have FICON-only environments, do not disable the default zone.
If you have FICON environments and plan to add (or already have) FC intermix on the switch,
ensure that all FICON host adapters and all FICON-capable device ports are in an explicitly
defined common zone.
