Abstract
A storage controller determines a difference between a control table containing fiber channel port configuration of an upper node device and security information, and information fetched from a name server, thereby detecting replacement of a fiber channel port and correcting the control table. This enables data input/output in the same way as before fiber channel port replacement without consciously modifying the security information.
