A control apparatus receives information on an abnormality in a relay apparatus including first and second monitor units provided in the relay apparatus to relay a communication among control apparatuses, from the first monitor unit to manage first information and execute a monitor of the relay apparatus, the abnormality being detected by the first monitor unit; and when the received information is information on an abnormality of a bridge unit to form a first communication route between the first monitor unit and the second monitor unit to manage second information and execute a monitor of the relay apparatus, executes a process for switching a communication route used to synchronize the first and second information between the first and second monitor unit, from the first communication route via the bridge unit, to a second communication route via communication lines connecting the control apparatus and the first and second monitor units.

Control apparatus, storage apparatus, and non-transitory computer-readable recording medium having stored therein control program

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.

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.

A collection unit collects attribute information of each of a plurality of electronic devices, and registers the collected attribute information in mounted device information correspondingly to a mounting position of the electronic device in a management system. A determination unit refers to device definition information in which attribute information of each electronic device mounted on the management system is registered correspondingly to a mounting position, determines as a comparison object position a mounting position in which the attribute information registered in the mounted device information is not matched with the attribute information registered in the device definition information and, when a plurality of comparison object positions are present, determines whether the attribute information of the mounted device information corresponding to one comparison object position is matched with the attribute information of the device definition information corresponding to another comparison object position.

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.

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 &#x201c;loop-down disk&#x201d;. The totalization result is compared with the threshold condition set for each RAID level (for example, &#x201c;unused disk&#x201d;=0 and &#x201c;loop-down disk&#x201d;='1 or more'), and the blocking possibility is determined.

A disc array device for maintaining consistency of data. When write processing is interrupted and then restarted, new data may be stored in a nonvolatile memory and regeneration of parity may be impossible because data can not be read out normally from a disc device other than a disc device in which new data is to be written and a disk device for parity. In such a case, a special write executing unit overwrites the new data stored in the nonvolatile memory at a specified write position of the disk device in which new data is to be written.

Disk array device

When it is determined in a disk replacement determining section that a disk has been replaced during system operation, a reference disk device is selected by a reference disk selecting section from disk devices other than a disk device having been replaced. The firmware (firmware storing area) of the reference disk device is copied into the replaced disk device.
