摘要： In an environment in which plural external storage devices having different function control interfaces are intermixed, when a function of a storage device is controlled from a computer, a common interface for controlling the function of the storage device is provided. A device that provides the common interface manages an interrelationship between a storage area recognized by a host computer and a storage area provided by the storage device and associates a storage area which becomes a target of a function control instruction with the storage device that provides the storage area. A type of the storage device that provides the storage area which becomes the target of the function control instruction is identified and function control is ordered through a function control interface unique to the device.

摘要： A host and a storage system each keep a shared identifier indicating a state of a system. The storage system acquires, at update of data, a data pair including data for a change through processing of the host and data before the update. The storage system relates the data pair to a shared identifier. When the host indicates an identifier, the storage system restores data using the data pair.

摘要： Provided is a storage system capable of starting/stopping a disk drive. At the time of allocating a logical device, it is judged, based on attributes including a purpose of the logical device, whether or not control can be performed in terms of start/stop of an allocation target disk drive to determine an allocation destination disk drive. Further, in the case where access to a specific logical device is stopped due to release of a path definition or other such cause, it is judged whether or not a disk drive corresponding to the logical device can be stopped. When it is judged that the disk drive can be stopped, the disk drive is stopped. When it is judged that the disk drive cannot be stopped, the logical device is migrated to another disk drive that can be stopped, a migration destination disk drive is stopped.

摘要： A migration destination storage creates an expansion device for virtualizing a migration source logical unit. A host computer accesses an external volume by way of an access path of a migration destination logical unit, a migration destination storage, a migration source storage, and an external volume. After destaging all dirty data accumulated in the disk cache of the migration source storage to the external volume, an expansion device for virtualizing the external volume is mapped to the migration destination logical unit.

摘要： For a storage system having plural control units to which plural disk devices are connected, in the method for creating replication in a volume of the disk devices connected to different control units, when receiving update I/O of a replication source during an initial copy for replication, the reflection of update to the replication destination is performed on an extension of the same I/O. When a pair is divided after the completion of copying, the update position is retained on the differential bitmap disposed in the individual control units, and the differential bitmap is merged to one of the control units at a time of resynchronization to perform copy processing.

摘要： In a cluster storage system, storage areas scattered in a plurality of storage nodes are coupled into a single storage area for access by a host computer. The cluster storage system has a first storage node and a second storage node, each of which has a disk and a control processor for controlling input/output to/from the disk, and a host interface node for connecting the first and second storage nodes to a computer. The first storage node manages a storage area having a first storage area existing in the first storage node and a second storage area existing in the second storage node as a logical device. Upon receipt of an access request having identification information corresponding to the logical device from the computer, the host interface node forwards the access request to the first storage node.
