  • Patent number: 7619965
    Abstract: In a system which manages path information and status of network with respect to a path being used for access to a storage apparatus and has a redundant path, when a fault occurs in the network, whether or not the path can be recovered by rerouting in network apparatuses is discriminated, thereby performing proper path switching. Construction information and the path information of the network are managed as information of the path which is being used for a storage access by a management server. Further, when the access path is made redundant, the management server obtains fault information in the network and information showing whether or not the path is being reconstructed from the network apparatuses, thereby discriminating the necessity of the path switching. If the path switching is necessary, the management server notifies a host computer and the storage apparatus of it and each apparatus executes a switching process.

  • Patent number: 7562109
    Abstract: The present invention decreases the burden of operation required for specifying the continuity status and the cause of failure of a network storage device. A host computer accepts the specification of the device identifier, that is an identifier of the network storage device in the host protocol which positions in a higher hierarchy than the network communication protocol, and a volume identifier, that is an identifier of the volume. Then based on the specified device identifier, the host computer specifies the network identifier, that is an identifier of the network storage device in the network communication protocol. And continuity is confirmed in the network communication protocol in which the specified network identifier is the destination. Also continuity is confirmed in the host protocol in which the device identifier is the destination. And the volume specified by the volume identifier is accessed.

  • Patent number: 7424341
    Abstract: A robot system efficiently performing an operation of moving a robot to close to and/or separate from a target point, such as teaching operation. A camera of a visual sensor is mounted to the robot such that a distal end of an end effector is seen within the field of view of the camera, and the end effector's distal end and a target position on an object are specified on a monitor screen. When an approach key is depressed, a target position is detected on an image, and a difference from a position of the end effector's distal end is calculated. Whether the difference is within an allowable range is checked. Depending on the result, an amount of robot motion is calculated, and the robot is operated. The processing is repeated until the depressed approach key is released. When a retreat key is depressed, the robot moves away from the object. The robot may be caused to stop using a distance sensor.
