Patent number: 9842070Abstract: A storage apparatus includes a plurality of control devices configured to control access a plurality of storage devices, and a relay apparatus including a plurality of coupling devices, each of which is configured to couple the control devices so as to be communicable with each other. The relay apparatus includes, for each coupling device, a monitoring controller configured to perform monitoring of the relay apparatus. A first monitoring controller provided in a first coupling device from among the coupling devices notifies, when the first monitoring controller detects an abnormal state in the relay apparatus, a first control device from among the control devices of information relating to the abnormal state detected by the first monitoring controller. The first control device performs a decoupling process that decouples an abnormal part from the relay apparatus based on the information relating to the abnormal state received from the first monitoring controller.Type: GrantFiled: March 14, 2016Date of Patent: December 12, 2017Assignee: FUJITSU LIMITEDInventors: Hirokazu Matsubayashi, Shoji Oshima, Tatsuhiko Machida

Patent number: 8972996Abstract: A processing function determination section included in an information processing apparatus determines a differential processing function which is a processing function that is realized by a first program and that is not realized by a second program. A control information determination section reads out relation information which associates a plurality of processing functions with one or more pieces of control information related to each of the plurality of processing functions from a storage section and determines a piece of control information related to the differential processing function on the basis of the relation information.Type: GrantFiled: February 10, 2011Date of Patent: March 3, 2015Assignee: Fujitsu LimitedInventors: Hirokazu Matsubayashi, Shoji Oshima, Tatsuhiko Machida, Satoshi Yazawa, Kouichi Tsukada

Patent number: 8255662Abstract: A reference-capacity calculating unit calculates a reference capacity of each of storage devices storing therein data on the basis of an actual capacity of each storage device. A difference calculating unit calculates a difference value between the reference capacity calculated by the reference-capacity calculating unit and the actual capacity of each storage device. A maximum-value retrieving unit retrieves the maximum difference value out of the respective difference values of the storage devices calculated by the difference calculating unit. A defined-capacity determining unit determines a defined capacity, which is an actually-used capacity of each storage device, on the basis of a value obtained by subtracting the maximum difference value from the reference capacity calculated by the reference-capacity calculating unit.Type: GrantFiled: December 23, 2010Date of Patent: August 28, 2012Assignee: Fujitsu LimitedInventors: Kouichi Tsukada, Satoshi Yazawa, Shoji Oshima, Tatsuhiko Machida, Hirokazu Matsubayashi

Patent number: 7779203Abstract: For each RAID group to be determined for blocking, each disk is classified into three types of totalization unit based on the status of each disk belonging to the RAID group or the presence/absence of an access path to each disk, and the number of disks corresponding to each totalization unit is totalized. The totalization unit is a “used disk”, an “unused disk”, and a “loop-down disk”. The totalization result is compared with the threshold condition set for each RAID level (for example, “unused disk”=0 and “loop-down disk”=‘1 or more’), and the blocking possibility is determined.Type: GrantFiled: September 29, 2006Date of Patent: August 17, 2010Assignee: Fujitsu LimitedInventors: Koichi Tsukada, Satoshi Yazawa, Shoji Oshima, Tatsuhiko Machida, Hirokazu Matsubayashi
