A management computer collects, from a storage subsystem via a management network, path definition information including the contents of a security setting made to a path accessible to a volume in the storage subsystem, and when the volume in the storage subsystem is an original volume having a replica volume, replica definition information of the original volume. Based on the replica configuration information thus collected from the storage subsystem, the replica relationship between the volumes is to be grasped. Then, based on the path definition information also collected from the storage subsystem, the contents of the path security setting are verified for the volumes under the same replica relationship, and the verification result is output. In such a structure, consistency verification can be easily done for the security setting of the original and replica volumes.

A management device of a storage device that executes CDP-based recovery comprises: a data protection term acquisition section that acquires a data protection term which is a term in which recovery of a data volume is ensured from a predetermined duration for which a predetermined time is a reference point; and a control section that executes control using the data protection term.

A wafer has an annular ridge formed along an outer periphery thereof to serve as a reinforcing portion, and a circuit pattern surrounded with the reinforcing portion. The wafer is placed on a wafer placement plane of a holding stage in a state that the circuit pattern is directed downward. The wafer placement plane is larger in size than the wafer. On the holding stage, a center of the wafer is aligned with a center of the holding stage in such a manner that a plurality of guide pins are engaged with relevant cutout portions formed on the reinforcing portion. Then, the holding stage rotates while suction-holding the reinforcing portion of the wafer, and simultaneously a photosensor detects a portion for alignment formed on the outer periphery of the wafer.

A SAN manager acquires configuration information from devices constituting a SAN and produces a corresponding relationship between a host computer and a virtual volume (virtual volume mapping) and a corresponding relationship between the host computer and a real volume (real volume mapping). Based on those pieces of mapping information, the SAN manager outputs a corresponding relationship between virtual and real volumes. Meanwhile, the failure notification messages received from the in-SAN devices are construed to detect and output an influence of the failure upon the access to a real or virtual volume. Furthermore, when receiving a plurality of failure notifications from the devices connected to the SAN, the plurality of failure notifications are outputted with an association based on the corresponding relationship between real and virtual volumes.

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.

To migrate a configuration that an old storage device has to a new storage device. A new storage device obtains a configuration of an old storage device, by using a migration manager, and prepares a logical volume definition of the new storage device based on a logical volume definition in the configuration. Also, based a cache allocation definition in the configuration and cache capacity of the new storage device, a cache allocation definition of the new storage device is prepared. Further, based on a port bandwidth allocation definition in the configuration and bandwidth capacity of a port of the new storage device, a port bandwidth allocation definition of the new storage device is prepared. The prepared logical volume definition, cache allocation definition and port bandwidth allocation definition are set up in a configuration of the new storage device.

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.

A cutter blade is cut-in by being moved towards a deep part of a notch from one open end of the notch while being moved in a forward direction with respect to an outer periphery of a wafer. Immediately before a blade edge reaches the deep part of the notch, cutting movement of the cutter blade is once stopped, reversely moved to a initial piercing position, and thereafter, the cutter blade is moved towards the deep part of the notch from the other open end of the notch while being moved in a reverse direction with respect to the outer periphery of the wafer.

An iron-base sintered part having high density and totally enhanced strength, toughness and abrasion resistance, a manufacturing method of the iron-base sintered part, and an actuator are disclosed. The iron-base sintered part is formed by an iron-nickel-molybdenum-carbon-based sintered alloy, has density of 7.25 g/cm3 or more, and has a carburization quenched structure. A method for manufacturing the iron-base sintered part includes a molding process of charging a raw mixture powder of an iron-nickel-molybdenum-based metal powder and a carbon-based powder into a cavity of a molding die and compressing the raw powder in the cavity to form a consolidation body, a sintering process of sintering the consolidation body at a sintering temperature to form a sintered alloy, and a carburization quenching process of heating the sintered alloy in a carburization atmosphere and quenching the heated alloy.
