ABSTRACT:
Method and apparatus for limiting access to control units channel-connected to host computers through a FICON switch. The control unit port of the FICON switch receives a requests from an attached host to provide configuration information regarding the switch ports. The control unit port deliberately misrepresents the port configuration of the switch by reporting that ports outside the zone of the requesting host are not installed, even though these ports may in fact be installed for use by other hosts that belong to other zones.
