Abstract: A storage apparatus comprises a controller. Another storage apparatus including a first communication port is coupled to a network, and a first identification number with which a server accesses a first storage area is set in the first communication port. A second communication port in the storage apparatus is closed when the storage apparatus is in a standby state. The controller controls access to the second storage area by opening the second communication port in a case where an operation of the other storage apparatus stops and the storage apparatus transitions to the active state, using the first identification number, and execute diagnosis of the second communication port by changing the first identification number to a second identification number and opening the second communication port in a case where the diagnosis is executed when the storage apparatus is in the standby state.

Abstract: A control device configured to backup data updated in response to update requests issued by a plurality of host devices, includes a memory; and a processor configured to: record, in the memory, a reception interval and a last reception time of the update requests for each host device, compare an elapsed time from the last reception time to a certain timing and the reception interval at the certain timing for each host device, and start the backup according to a comparison result for each host device.

Abstract: A storage control apparatus includes a memory and a processor. The memory stores selection condition information relating to a selection condition for storage devices to construct a RAID, group information relating to groups to which the storage devices belong, and connection information indicating a connection configuration of the storage devices. The processor is configured to perform a procedure including: selecting the storage devices that match the selection condition information; extracting groups to which the selected storage devices belong based on the group information; assigning group priorities, which indicate selection priorities in units of the groups of the storage devices, to the extracted groups based on the connection information; and selecting one storage device from each of the extracted groups in accordance with the group priorities until a predetermined number of storage devices have been selected.

Abstract: An information processing apparatus includes a memory, and a processor coupled to the memory and configured to set, in the memory, a first region having a first capacity, receive a first request which requests to change the first region to a second region having a second capacity greater than the first capacity, set, in the memory, the second region and a reserved region in response to the first request, and cancel a setting of the reserved region when a second request which requests to change the second region to a third region having a third capacity greater than the second capacity is not received within a first time period after the first request is received.

Abstract: According to an aspect of an embodiment, a disk drive diagnosis apparatus is included in a RAID system in which a RAID control unit and a drive enclosure that encloses a disk drive are interconnected via a fabric switch. The apparatus comprises a virtual login processing unit configured to virtually execute a login process for a fabric switch of a disk drive and a control unit configured to notify the RAID control unit of a result of the virtual login process and disconnect from a connection line for the RAID control unit a disk drive that has not normally performed the virtual login process relative to the drive enclosure.

Abstract: A storage apparatus and method are provided. The storage apparatus including includes a basic storage device having a control unit and an add-on storage device configured to be connected to the basic storage device. The add-on storage device including a first request receiving unit receiving a first operation stop request output from the basic storage device to the add-on storage device second request receiving unit receiving a second operation stop request different from the first operation stop request, communication monitoring unit monitoring communication from the basic storage device, and operation stop processing unit performing processing for stopping the operation of the add-on storage device. The operation stop processing unit determines the validity of the second operation stop request on the basis of a monitoring result obtained by the communication monitoring unit, and stops the operation of the add-on storage device.

Abstract: A storage apparatus having a plurality of storage units for storing data comprises: a detecting module for detecting status information indicative of the operation environment of said storage apparatus; a controlling module for accessing said data in said storage unit, said controlling module performing processing in accordance with said status information; and a relaying module for relaying said data between said controlling module and said storage units, storing the status information, and transmitting said status information stored in said relaying module to said controlling module in response to a request from said controlling module.

Abstract: Disclosed is a non-heat treated steel for hot forging, particularly suitable for producing connecting rods of automobile engines. The steel consists essentially of: by weight, C: 0.3-0.8%, Si: 0.1-2.0%, Mn: 0.3-1.5%, P: 0.01-0.15%, Cr: 0-1.0%, V: 0-0.4%, Al: 0-0.05%, N: 0.005-0.03% and the balance being Fe and inevitable impurities, provided that the contents of C, Mn and Cr fulfill the following condition: 1.40[C %]+0.28[Mn %]+0.50[Cr %]?0.75 Pearlite area fraction in this steel after hot forging is 50% or more. Notches are provided with laser beam on an intermediate part at the location from which fracture starts, and load is applied. Then, the intermediate is split to be two components (big end or cap and small end/rod for connecting rod). The components are adhered to form the parts.

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.
