| 摘要 | A controller includes an address generator that sets a plurality of different paths, each connecting an information processing apparatus connected to a storage apparatus via a network, first and second storage mediums, and the controller, and generates a second address that is different from a first address used for a communication with the information processing apparatus via the network; an access monitor that determines that no access has been issued for a certain time duration from the information processing apparatus to the first or second storage medium; an access issuing unit that issues a test access to the first and second storage mediums on one of the paths, using the second address; and an access decoder that converts the test access to an access including the first address, receives a result of the access including the first address from the first or second storage mediums, and checks for an error. | ||

| 主权项 | 1. A controller comprising: an address generator that sets a plurality of different paths, each connecting an information processing apparatus connected to a storage apparatus via a network, first and second storage mediums, and the controller, and generates a second address that is different from a first address used for a communication with the information processing apparatus via the network; an access monitor that determines that no access has been issued for a certain time duration from the information processing apparatus to the first or second storage medium; an access issuing unit that issues, in response to the access monitor determining that no access has been issued for the certain time duration from the information processing apparatus, a test access to the first and second storage mediums on one of the plurality of paths, using the second address; and an access decoder that converts the test access to an access including the first address, receives a result of the access including the first address from the one of the first and second storage mediums, and checks for an error, wherein the access issuing unit issues the test access preferentially on one of the plurality of different paths, based on a history of usage of the storage apparatus. | ||
