A snapshot volume is migrated by using a primary volume of a migration destination storage apparatus.The management server comprises a controller for generational management, by means of the snapshot volumes, of differential data for the logical volume which is the parent volume of the snapshot volume, and, if an instruction to copy a snapshot volume of a designated generation is received and a snapshot volume prior to the designated generation of the copy instruction-target snapshot volume exists, the controller copies the differential data between the designated-generation snapshot volume and the existing snapshot volume, and associates the copied differential data with the existing snapshot volume.

A golf ball of the present invention includes: a core located in the center of the golf ball; a cover surrounding the outside of the core and having plural dimples on the surface thereof; a paint layer surrounding the outside of the cover; and a top coat further surrounding the outside of the paint layer. The paint layer is formed of a material having rubber elasticity. The top coat may have a thickness of at most approximately 60 μm. A material for forming the paint layer has a first loss tangent, a material for forming the cover has a second loss tangent, and a difference Td between the first loss tangent and the second loss tangent may be at least approximately 0.05.

A data storage or management method is provided which allows both a content object-based access and a file-based access. A first request for storing a content object in accordance with the processing of an application program executed in a host is sent to an object archive control functionality executed in the host, an intermediate server, or a storage apparatus. The object archive control functionality generates an object identifier corresponding to the content object received in response to the first request, a directory name corresponding to the object identifier, and a plurality of file names corresponding to a plurality of fields contained in the content object. The storage apparatus stores a directory having the directory name and the plurality of files having the plurality of file names in accordance with the second request.

A method for drying workpieces includes immersing the workpieces in a liquid bath, raising the workpieces with a first holder until a central opening of the workpieces is visible above liquid surface, then using a dry second holder rod inserted through said central opening to continue raising process. Due to this, a drying portion of the workpieces is not held by a wet holding mechanism.

A base member on which a plurality of components are mounted includes a base main body, a coating formed on a surface of the base main body, and a display portion formed by a contrast between the coating and the surface of the base main body. The display portion displays a state by which it is determined whether or not the base main body has been machined in accordance with a corresponding machining program.

A storage system capable of identifying all volumes to be audited is provided.Operation logs 3005 concerning the operations of volumes are associated with a time and stored in storage apparatuses 1400 and 1500, and a management computer 1100 collects information about these operation logs 3005, restores the status history of the operation logs 3005, sets, as an audit range, the operation logs 3005 including volumes with an audit period and audit target data stored therein, extracts the operation logs 3005 belonging to the audit range from the restored status history of the operation logs 3005, and transmits the extracted operation logs 3005 to a computer (requesting computer) 1000. As a result, all the audit target volumes can be identified.

摘要:
There is provided a computer system comprising a first storage system and a second storage system coupled to the first storage system. The first storage system provides a first storage area. The second storage system provides a second storage area. The second storage system reads and writes the requested data from and to the first storage area associated with the second storage area; specifies the first storage area associated with the second storage area from which the data is to be erased upon reception of a request for erasing the data stored in the second storage area; and transmits the request for erasing the data to the first storage system providing the specified first storage area. The first storage system erases the data stored in the specified first storage area, based on a data erasure condition included in the request for erasing the data.
摘要:
The load of managing a storage system is lessened. In a storage system where multiple logical volumes are included in a logical volume group and a copy of the logical volume group is made in a pool area different from the one to which the logical volume group belongs, a management computer adds to the pool area capacity when the capacity of a pool area exceeds a predetermined threshold. When the pool area includes multiple logical volume groups, the management computer requests the storage system to create a pool area for each of the logical volume groups and to create the logical volume groups respectively for the created pool areas. When the pool area includes one logical volume group, the management computer requests the storage system to make the capacity of the pool area coincide with the capacity of a pool area to which the logical volume group is copied.
摘要:
An object of the present invention is to provide a storage system and storage management method, which prevent a problem in the operation of stored data from being caused by unknown states of volume information and life information, when flash memories are placed in off-line mode and again placed in on-line mode. According to the present invention, there is provided a storage system 1200 which has flash memories 1300 constituting a storage area and a function of placing and handling the flash memories in off-line mode and on-line mode, and which stores and manages management information of the flash memories in on-line mode, the storage system including: when some or all of the flash memories in on-line mode are placed in off-line mode, creating a management area in off-line mode in the flash memories by moving existing data in an area used as the management area to an area other than the management area; writing the management information of the flash memories to the created management area; and placing the flash memories in off-line mode.
