摘要： A physical storage area that is allocated to an unused area of a virtual volume is removed. A management unit sends a request to a server computer to make every piece of data stored in a first logical volume migrate to a second logical volume. The server reads all the data out of the first logical volume and writes the data in the second logical volume. A storage system that includes the first logical volume and the second logical volume allocates a physical storage area to an area of the second logical volume where the data is to be written, and writes the data in the allocated physical storage area. The storage system then deletes the first logical volume.

摘要： In one embodiment of an image forming apparatus according to the invention, an overwrite-block specifying device specifies equal size blocks so that a storage area in a data storage device is divided into consecutive equal size blocks to be overwritten with overwrite data. The data storage device includes an image data storage area configured to store encrypted image data on a page-by-page basis. An overwrite-data specifying device specifies the value of the overwrite-data whose size is smaller than that of the equal size block. A data erase control device overwrites the equal size blocks with the value of the overwrite-data, on a block-by-block basis.

摘要： The present invention provides effective use of a storage resource in a system where a storage area of a logical volume is dynamically extended and reduced. In an information processing system including a management device communicably connected to a storage device that can dynamically change a storage capacity of a virtual volume allocated to a host computer, when a used amount of a certain storage pool exceeds a threshold set in the storage pool, the management device sends to the storage device, an instruction to migrate a predetermined number of virtual volumes, sequentially selected in ascending order of capacity increasing rate, so that another storage pool different from the certain storage pool may be used as a creation source. At this time, as a migration destination, the management device uses, the storage pool having, for example, an attribute of the storage resource identical to that of the certain storage device.

摘要： A managing computer (manager) manages replication of data areas inside a storage or among storages. A storage volume management module of the manager manages policy of the volume and its properties. When replication of a volume is set, a volume of a replication destination appropriate for a volume of a replication source is generated using the policy and the properties to form a replication pair. A route management module of the manager and its volume management module bring the policy and the properties of the volumes, and the policies and conditions of lines into conformity with one another. When any fault occurs in a line route used for data transfer during replication of the volume, a separate line route is utilized, and a fault countermeasure is taken for replication of the volumes in accordance with the policy and properties of the volumes.

摘要： A management computer manages the pool application information that indicates a pool application for a pool and the application condition information that indicates the condition for the pool application. The management computer calculates an excess storage capacity based on a pool usage status for the pool. The management computer specifies a pool application for the pool and the condition for the pool application based on the pool application information and the application condition information. The management computer judges whether the specified condition is satisfied even in the case in which a storage area having a storage capacity equivalent to or less than the calculated excess storage capacity is deleted from the pool. In the case in which the result of the judgment is positive, the management computer defines a capacity equivalent to or less than the excess storage capacity as an unused capacity.

摘要： A discrepancy between a management range of a user on a management computer and a management range of the user in a storage, is detected with respect to a volume held in the storage. Storage management information of the management computer stores a correspondence between an identifier of a volume group, and a identifier of the user. When a plurality of volumes are designated as a managed object of the user, the management computer references the storage management information, and obtains, from the storage, an identifier of the volume group to which the plurality of designated volumes belong. Next, the management computer references the storage management information, and determines whether or not the obtained volume group is in management range of the same user.
