A storage apparatus including: a first controller that generates an access to a storage device; the first controller includes: a first relay unit configured to relay the access to the storage device; and an access control unit configured to be activated after activation of the first relay unit and to relay the access to the storage device via a second relay unit; and a second controller that includes the second relay unit and generates the access to the storage device, wherein when the first relay unit receives a connection request for an access path between the first relay unit and the storage device from the second controller, the first relay unit establishes the access path to the storage device irrespective of an activation state of the access control unit.

Storage apparatus and controlling method of storage apparatus

A logical path establishing method establishes a logical path between peer-to-peer in a peer-to-peer remote copy (PPRC) function. The logical path establishing method uses a step of including a link control frame for controlling a link in a frame which is used as a unit of information transfer, so as to include information necessary for establishing the logical path in the link control frame.

Logical path establishing method and storage medium

Disclosed is a driving circuit of a gas discharge panel comprising X-electrode rows and Y-electrode columns arranged in a matrix. In order to decrease the number of driving elements, the X-electrode driver is comprised of a first up drive circuit commonly used for applying a discharge sustaining voltage and a write-in voltage to the X electrodes, and a first down drive circuit for grounding the first up drive circuit when the discharge sustaining voltage or the write-in voltage is not applied to the X electrodes. Also, the Y-electrode driver is comprised of a second up drive circuit for applying a discharge sustaining voltage to the Y electrodes, a second down drive circuit for grounding the second up drive circuit when the discharge sustaining voltage is not applied to the Y electrodes, a write-in driver for applying a write-in voltage to the Y electrodes, and a clamping circuit for grounding the Y electrodes when the write-in voltage is not applied to the Y electrodes.
