摘要： A volume management system, a managing computer, a host, and a volume management method being capable of regulating the authorities of users and avoiding misoperations are provided. The volume management system comprises a storage having volumes served as a storage region, a managing computer, and a plurality of hosts used by users obtaining an operation authority over the volume. Two or more users can use an identical volume. Upon obtaining an operation content of one user for at least one of the volumes over which two or more users have the operation authority, the managing computer determines from an attribute of the volume and the operation authority of the two or more users over the volume whether the operation content is executable. When the operation content is not executable, the operation content is restrained.

摘要： A management computer monitors an allocated capacity of a source virtual volume and an allocated capacity of a virtual pool having a storage area allocated to a destination virtual volume in a storage, judges whether the allocated capacity of the source virtual volume can be covered in the virtual pool or not, and informs the user of a result that data migration fails when the allocated capacity of the source virtual volume cannot be covered. When the allocated capacity of the source virtual volume cannot be covered, the management computer uses another storage area to increase the capacity of the virtual pool. Accordingly, when data migration is performed between the virtual volumes, capacities of physical areas allocated to the source virtual volume and the destination virtual volume can be grasped so that the data migration can be performed accurately between the source virtual volume and the destination virtual volume.

摘要： The object of the present invention is to prevent distribution of a storage range to a volume from an inappropriate disk drive based on use of the volume as a result of an automatic extension of a volume capacity. A computer system has a storage system including a physical storage device, a host computer, and a management computer. The storage system includes a plurality of kinds of physical storage devices physically dividing into two segments or more the volume and records as constitution information the correspondence between each segment and the volume using the segment. And the storage system records the kind of physical storage device to be allocated to the volume and selects the physical storage device according to the kind of stored physical storage device for allocation of the segment when the host computer performs an I/O access to the volume. Access frequency is monitored and data is copied based on the monitored access frequency.

摘要： A storage system includes physical memory devices, pool volumes, including real areas, an allocation-on-use (AOU) volume including virtual areas, and a controller allocating a non-allocated real area in a pool including the pool volumes to a virtual area corresponding to an address specified by a writing command when no real area is allocated to the virtual area, and writing data corresponding to the received writing command to the allocated real area. The controller moves data stored in all the real areas in a first pool volume allocated to the AOU volume to a second pool volume, and changes a power consuming status of the physical memory device constituting the first pool volume to a power saving mode after the data has been moved.

摘要： Provided are a backup data management system and a backup data management method capable of facilitating the management of backup data that is multiplexed between different storage apparatuses. The backup data management system includes a storage apparatus having a volume to be used by a host computer, at least one storage apparatus having volumes, and a management computer. The management computer creates a copy pair so that a snapshot of the volume included in a backup group is stored in all the volumes included in the backup group, and sets all copy pairs included in the designated backup group to a PAIR status when there is a creation request of the snapshot of the volume.
