Abstract
N_Port_Name information capable of distinctly identifying a host computer has seen set in a microprocessorof a storage controllerprior to start-up of host computers; upon startup of the host computers, when the storage controllerreceives a frame issued, then the microprocessoroperates to perform comparison for determining whether the N_Port_Name information stored in the frame has been already set in the microprocessorand registered to the N_Port_Name list within a control table maintained. When such comparison results in match, then continue execution of processing based on the frame instruction; if comparison results in failure of match, then reject any request.
