  • Storage system, virtualization control apparatus, information processing apparatus, and method for controlling storage system
    Patent number: 9524251
    Abstract: An information processing apparatus is configured to make access to a storage device via a first path. A virtualization control apparatus is configured to control access to a virtual storage device via a second path, where the virtual storage device is provided by virtualizing the storage device. The virtualization control apparatus sends an identifier of the storage device in response to a query from the information processing apparatus which requests information about a storage space that is accessible via the second path. The information processing apparatus incorporates the second path as an inactive standby path when the identifier received as a response to the query matches with an identifier of the storage device accessible via the first path.
    Type: Grant
