Abstract: The storage apparatus includes a plurality of storage devices for storing information, a control unit controlling the storage device, a switching unit switching a connection between the storage device and the control unit, and a network different from the connection by the switching unit and connecting the storage device and the control unit. Reading of information from the storage device and writing of information into the storage device is performed by the control unit through the switching unit, and when a fault occurs in the storage device, a fault recovery command is sent from the control unit through the network to the corresponding storage device or the switching unit.

Abstract: A relay device having a plurality of physical ports connecting with a storage medium and relaying data between a higher level device storing configuration information of a storage device and the storage medium, the relay device including a notification unit for issuing a status change notification reporting that a status of the storage medium connected with said physical port changes to said higher level device when the status change of the storage medium is detected, a monitor of status change notification frequency for monitoring whether the frequency of the status change notification informed via said physical port exceeds a specific threshold, and an invalidation unit for invalidating a function of said physical port when said monitor of status change notification frequency detects that the frequency of the status change notification informed via said physical port exceeds the specific threshold.
