摘要： A host computer acquires remote copy status information of storage subsystems that are not directly coupled to the host computer. Each storage subsystem comprises: a unit which receives a status information acquisition command from the host computer; a unit which analyses the received command to judge whether the storage subsystem in question is a target of the command; a unit which sends the command to a downstream storage subsystem connected to the storage subsystem in question when the storage subsystem in question is not the target; and a unit which sends status information to an upstream storage subsystem connected to the storage subsystem in question when the status information is received from the downstream storage subsystem.

摘要： Storage area assignment is specified in accordance with control modes for the cache memory. A storage apparatus which is connected via a network to a host which issues data I/O requests comprises storage devices of a plurality of types of varying performance, and a control unit which manages each storage area provided by each of the storage devices of a plurality of types by means of storage tiers of a plurality of different types, and which assigns storage areas in predetermined units to virtual volumes from any storage tier among the storage tiers of a plurality of types in accordance with a data write request from the host, wherein, if there is an I/O request from the host, the control unit stores data corresponding to the I/O request in predetermined units in the cache memory and determines the storage tier of the storage area assigned to the virtual volume storing the data according to the mode of writing to the cache memory.

摘要： The identification information about unnecessary files is registered to generate an unnecessary-file database. The identification information about files stored on a plurality of storage devices connected to a host computer is acquired to judge with the unnecessary-file database whether the identification information about files conforms to unnecessary-file conditions. Files nonconforming to the unnecessary-file conditions are checked to determine whether they are already migrated to a different storage device. If all the files stored on a storage device conform to the unnecessary-file conditions or are already migrated to a different storage device, the identification information about the former storage device is displayed to indicate that the storage device can be removed.

摘要： In a computer system, to enable a second computer to take over control of copying of data within the computer system, from a first computer that normally controls copying of data. The second computer selects from a plurality of storage systems a storage system to be accessed in order to acquire sub system pair information, and acquires sub system pair information from the selected storage system. Based on the acquired sub system pair information, the second computer generates system pair information that includes copy pair information relating to a plurality of storage areas belonging to the plurality of storage systems. The second computer initially selects a storage system directly linked to the second computer, and subsequently sequentially selects a storage system based on the acquired sub system pair information.

摘要： An example of the present invention is a storage system comprising a first real storage apparatus including a plurality of real resources. The first real storage apparatus includes: real resource groups allocated to a plurality of virtual storage apparatuses; first management information for associating virtual resource identifiers individually assigned to real resources in a namespace independently defined for each of the plurality of virtual storage apparatuses with real resource identifiers individually assigned to the real resources in a namespace defined for the first real storage apparatus; and a controller for receiving a command including a designation with a virtual resource identifier, converting the virtual resource identifier in the command into a real resource identifier with reference to the first management information, and processing the command with the converted real resource identifier.
