Patent number: 7822894Abstract: The present invention unitarily manages the configuration change of a storage system so as to know the latest configuration, and evaluates the reliability in advance when the configuration is changed so that the generation of a failure is suppressed. When the host 1 is connected to the switch 2, the attribute information of HBA 1A and the attribute information of the switch 2 are stored in the connection information storage unit 2C by FDMI (Fabric Device Management Interface) (S1, S2). Each attribute information is associated with each other and is managed as combination information. The storage device 3 acquires the combination information from the switch 2 (S3, S4), and requests the management device 4 to judge the reliability of this combination (S5). The management device 4 judges the combination of the HBA and the switch (S6), and notifies this judgment result to the storage device 3 (S7).Type: GrantFiled: October 16, 2007Date of Patent: October 26, 2010Assignee: Hitachi, LtdInventors: Toru Harima, Tatsuo Namba, Katsuhiro Uchiumi, Naoki Futawatari, Itaru Isobe

Patent number: 7373474Abstract: Techniques for realizing efficient setting and utilization of configuration including storage volumes in a storage system having an initiator and a target, with a low cost configuration not requiring additional equipment such as a LAN and a server without limitations due to a low-transfer rate network are provided. The storage system has, e.g., an IS serving as an initiator, a TS serving as a target, and a frame relay device R for relaying the communication between the devices. The R has a DB for retaining the configuration information including the configuration of storage volumes in plural devices connected via plural ports, and an exclusive control unit for performing an exclusive control process of the configuration information in the DB upon setting for utilizing the storage volumes among the plural devices. According to update of the configuration of each device, the R updates the configuration information in the DB.Type: GrantFiled: June 6, 2005Date of Patent: May 13, 2008Assignee: Hitachi, Ltd.Inventors: Yoshihisa Honda, Yoshihito Nakagawa, Keishi Tamura, Itaru Isobe
