Abstract: A cable holding device for holding a cable, includes a first member, a second member and a fixing member. The first member has a first through hole through which the cable is to pass. The second member has a second through hole through which the cable is to pass. The fixing member fixes the second member to the first member in such a condition that the second through hole partially overlaps the first through hole to hold the cable by an inner periphery of the first through hole and an inner periphery of the second through hole.

Abstract: A safety device for a wall surface suction-type travel device that is configured to travel on a wall surface while being suctioned on the wall surface includes an extending member, a support base, and a safety rope. The extending member is configured to be disposed on the wall surface and bendable by self weight. The support base supports the extending member so as to allow the extending member to move in a direction along which the extending member extends. The safety rope connects the extending member with the wall surface suction-type travel device.

Abstract: An information processing apparatus 10a according to the present disclosure includes: a touchscreen panel 14 on which video is displayed and which accepts an operation that has been performed by a user; a detector 21 which detects the operation that has been performed by the user on the touchscreen panel 14; and a processor 20 which performs processing in response to the operation. If the user has performed the operation using a polyhedron input interface device 10b which has a plurality of sides in mutually different shapes, the detector 21 detects the shape of an area in which the input interface device 10b is in contact with the touchscreen panel to determine which side of the polyhedron has been used to perform the operation, and the processor 20 carries out processing that is associated with the side that has been used.

Abstract: A method for displaying a state of a copy pair which is a pair of logical volumes belonging to one or a plurality of storage sub systems connected to a task server, including: monitoring periodically, by a backup management program on the task sever, an operation condition of an application on the task server; notifying, by the backup management program, a maintenance to a control program on the storage sub system, if the application is on a stop condition at some time; setting, by the control program which receives the notification, “on-maintenance” to an action mode on the storage sub system; after a maintenance by a user and at time of a restart of the application, checking, by the backup management program, the operation condition of the application and notifying a release of the maintenance to the control program; and setting, by the control program which receives the notification of the release, the action mode of the storage sub system to a normal condition.

Abstract: The present invention is to provide a method for displaying a copy pair in which a distinction can be made between change of pair state performed intentionally by a user and change of pair state performed not intentionally by the user. When a backup instruction for PVOL is transmitted from the task server to the storage subsystem, the subsystem records, on a table, backup execution condition information including an ID of a copy pair having the PVOL. The monitoring program acquires the pair state of each copy pair and the backup execution condition information from the subsystem, and displays the pair state of the copy pair having the ID contained in the backup execution condition information, and the pair state of other copy pair, in different display modes.

Abstract: A storage system has a cache memory, a side-file being a storage area prepared in memory, and a copy source storage device. Each time write data is received, the storage system writes the write data to the copy source storage device via the cache memory, and also writes the received write data to the side-file. The storage system sends the plurality of write data accumulated in the side-file to another storage system at a certain timing. Thus, the plurality of write data stored in the copy source storage device is written to the copy destination storage device in the other storage system.

Abstract: A storage system includes an application server that provides an application composed of a plurality of programs, a plurality of first volumes that store data that the programs use, and a plurality of second volumes set in pair states where replicas of the plurality of first volumes are stored. A program for managing the storage system controls a computer to execute the procedures of: identifying any one of the plurality of programs; identifying a first volume that the identified program uses; obtaining every second volume set in a pair state with the first volume; and summarizing the first volume and the obtained second volume for the identified program.

Abstract: The present invention is constituted so as to enable more effective backup and restoration than in the prior art. Each time a write request is issued from an application 47, a PVOL is updated by writing the data contained in the issued write request to the PVOL 43P. In the snapshot mode, when the write frequency exceeds a frequency threshold value, the mode is switched from the snapshot mode to the journal mode. When in the snapshot mode, a snapshot of the PVOL at this point in time is acquired, either at regular or irregular intervals, for a SVOL 43S, and the snapshot in this SVOL becomes the restoration data. When in the journal mode, a journal comprising the data in a write request is written to a JVOL 43J each time the write request is issued, and a backup, to which is applied the data in a journal written to the JVOL, is acquired when executing restoration.
