    摘要: A storage device includes a S.M.A.R.T. information processor that periodically diagnoses physical and functional condition of the storage device and stores diagnostic information about the condition of the storage device in a magnetic disk and a storage unit. Upon receiving a request for the diagnostic information from a host computer, the S.M.A.R.T. information processor determines whether the magnetic disk is in standby mode. The S.M.A.R.T. information processor acquires the diagnostic information from the storage unit if the magnetic disk is in standby mode, and notifies the diagnostic information to the host computer.

    摘要: A disk managing apparatus is configured so that an operation mode of a disk device is set to be in a standby mode by default and an access managing unit continuously acquires an operation state of the disk device. Upon receiving a disk access request, and if the operation mode is the standby mode, the access managing unit checks the operation mode and sends a query about accessibility of the disk device to the power managing unit. Upon receiving an access permission, the access managing unit accesses the disk device and switches the operation mode to be in the active state. Furthermore, the data-transfer processing unit transfers frequently-accessed data to a frequently-accessed disk device.

    摘要: In a device control apparatus, a state judging unit, to which an I/O request received by an I/O request receiving unit is passed, acquires a device state by issuing a state check command to a control command queue of a magnetic disk device. When the device state acquired is normal, an I/O requesting unit issues an I/O command to an I/O command queue of the magnetic disk device. When the device state acquired is not normal, an I/O response notifying unit notifies a request source of the I/O request of error information of the device state.

    摘要: A bad sector is detected by activating a bad sector detecting function of a recording apparatus at a predetermined interval. The bad sector is recovered, when the bad sector is detected at the detecting, by overwriting data on the bad sector with a duplication of the data, and when overwriting fails, by writing the duplication of the data on other sector.

    摘要: In a storage system, a plurality of RAID devices are connected to a network, and data is multiplexed to primary data and secondary data by being mirrored among the RAID devices. When a failure of a disk device that can be recovered within the devices owing to the RAID configuration occurs, data of a disk device corresponding to the failed disk device is requested to a RAID device that is its mirror target and the transferred data is written to a spare disk device for the recovery. At the time of the data recovery, an access right to a group of disk devices constituting RAID and an access right to individual disk devices are exclusively controlled with respect to an input and output of the primary data.

    摘要: There are connected a plurality of hosts 1 to L, a plurality of targets 1 to M and a plurality of initiators 1 to N, through a network. Each target has a managing unit which decides by itself the target search information broadcast from the initiator onto the network. In the case it is suited for data storage in the own target, data storage response information containing accepted priority information is broadcast onto the network. The target largest in priority value is notified of target selection from the initiator, thus effecting data storage.

    摘要: A plurality of storage nodes are connected via a network to build a storage system. Each of the storage nodes includes a storage device. A condition holding unit holds a state condition indicating an inactive state and an active state of the storage device. A state control unit controls a state of the storage device between the inactive state and the active state based on the state condition held by the condition holding unit.
