A computer system comprising a storage device including a copy pair of a copied volume and a host computer is provided. The management computer detects a change in the state obtained by monitoring the state of the copy pair, and according to the result of detection, changes the configuration of a cluster constituted by a virtual machine using data stored in the volume, and a host computer using the volume.

Provided is a storage apparatus operable to prevent incomplete backup and perform efficient backup even in systems characterized by a relatively small backup window and high degrees of utilization by users. This storage apparatus performs a snapshot of a volume storing data, using a logoff or login request at a certain point in time within in the backup window as a trigger, and creates a replication volume of the volume based on the acquired snapshot. To achieve the data consistency, when a login request is made, the storage apparatus temporarily suspends processing for establishing a session until the snapshot is created, and resumes such processing for establishing the session based on a login request after the snapshot is created. In one implementation, the replication volume is created in the background.

Upon detection of a virus definition file update, a virus check server mounts a computer's storage area in a storage apparatus via a network to check whether or not a file stored in the storage area is infected with a virus. For the virus check, the virus check server communicates with the storage apparatus via a path different from the one that is laid between a user computer and the storage system. Therefore, a virus check executed by the virus check server does not lower the computer's communication speed and disk access speed.

A bending angle detection system capable of detecting a bending angle of a workpiece with high accuracy, wherein taking into account the fact that the brightness of a linear image formed on a surface of a workpiece is higher than that of a linear image formed on other areas than the workpiece, linear images picked up from the workpiece are automatically sorted out from linear images picked up from other areas according to differences in the brightness values of the linear images so that only the data representative of the linear images formed on the workpiece can be extracted.A linear projected light image formed on the workpiece surface is picked up by a CCD camera, a representative pixel of each scanning line on the picked up, multi-valued linear image is calculated by a representative pixel detecting unit. Based on the frequency distribution of the brightness values of the representative pixels, the workpiece representative pixel extracting unit extracts only the representative pixels associated with the linear projected light image formed on the workpiece from all the representative pixels. Based on the extracted representative pixels, a representative straight line is calculated to obtain a bending angle of the workpiece.

A storage system configured to associate a virtual port 810 to a plurality of physical ports 800. In response to commands from computers, the storage system 100 manages relation between physical ports and virtual ports and relation between virtual port and volumes by performing processes such as creating a virtual port, assigning LUs to a virtual port, moving a virtual port between physical ports and deleting a virtual port. The storage system also maintains/calculates statistics information for ports and displays the information for each virtual port.
