    摘要: Proposed is technology for shortening the time required for analyzing and processing commands issued from multiple hosts and speeding up the processing. When a controller receives a command including random IO processing and the reception of commands is complete, it determines whether the valid extents prescribed in seek parameters attached to an LOC command overlap, and executes extent exclusive wait processing which causes access to the logical volume to enter a wait state or access processing to the logical volume based on the determination result. If the reception of commands is incomplete, the controller determines whether the access ranges (extents) designated in a DX command overlap, and executes extent exclusive wait processing or access processing to the logical volume based on the determination result.

    摘要: Provided is a storage system enabling the addition of a storage apparatus without going offline. When a first storage apparatus receives from a host system a command for writing first data in any one of the primary volumes in a primary volume group, it writes the first data in the relevant primary volume and sends to a second storage apparatus a first command for writing the first data in a secondary volume specified using first mapping information. When the second storage apparatus receives from the host system a command for writing second data in any one of the secondary volume groups in a secondary volume group, it writes the second data in the relevant secondary volume and sends to the first storage apparatus a second command for writing the second data in a primary volume specified using second mapping information.

    摘要: When a double failure occurs in a storage device storing a mutual conversion table such as a track management information table in thin provisioning, the storage address of the track within the storage subsystem cannot be specified and user data is lost. In order to solve the problem, the present invention provides a storage subsystem capable of recovering data by referring to a track address stored in an accessible track management information table or a user data section, renewing the damaged track management information table to restore the corresponding relationship between track management information tables, and enabling the user data to be accessed again.

    摘要: Each actual page inside a pool is configured from a plurality of actual tracks, and each virtual page inside a virtual volume is configured from a plurality of virtual tracks. A storage control apparatus of a mainframe system has management information that includes information denoting a track in which there exists a user record, which is a record including user data (the data used by a host apparatus of a mainframe system). Based on the management information, a controller identifies an actual page that is configured only from tracks that do not comprise the user record, and cancels the allocation of the identified actual page to the virtual page.

    摘要: A storage apparatus comprises a disk device and a disk controller for controlling the disk device. The disk controller provides a data volume including an actual volume and virtual volume with a volume capacity virtualization function. The virtual volume is associated with a pool volume for storing the actual data and the actual data is stored in the pool volume. In response to a write command from a host computer, the disk controller compresses write data under RAID 5 control and stores the compressed data in a storage area in the actual volume. If the entire compressed data cannot be stored in that storage area, the disk controller stores the remaining portion of the compressed data in the virtual volume.
