Abstract:
1. A storage control system comprising: a host computer having one or more initiators; a storage controller having one or more targets and storage areas, and also having a security property that defines access relationships between the one or more targets and the storage areas; and a server having a first memory for storing correspondence relationships between the one or more initiators and the one or more targets, and the storage controller having a second memory, wherein the server notifies the host computer and the storage controller of the correspondence relationships, wherein, the host computer, the storage controller and the server are connected to each other via a communication network, wherein the storage controller sets, based on the correspondence relationships received as notification from the server, the security property in such a manner that an initiator can access a specified storage area via a target, the initiator and the target having been notified of the correspondence relationships, wherein the correspondence relationships stored in the first memory comprise: a domain information table comprising domain information, which comprises domain names and groups of initiators and corresponding targets, wherein the groups of initiators and corresponding targets are allocated to a domain corresponding to a respective domain name; and a device information table comprising device information for the one or more initiators and the one or more targets, wherein the device information table comprises state change notification information indicating whether the server is to notify the one or more initiators and the one or more targets of post-change domain information when any change in the correspondence relationships is registered at the server, and wherein the storage controller receives the post change domain information from the server, registers the post change domain information in the second memory, and establishes correspondence relationships between specified management units and the one or more initiators belonging to the groups of initiators and corresponding targets.
