摘要： A storage system of this invention maintains consistency of the stored contents between volumes even when a plurality of remote copying operations are executed asynchronously. A plurality of primary storage control devices and a plurality of secondary storage control devices are connected by a plurality of paths, and remote copying is performed asynchronously between respective first volumes and second volumes. Write data transferred from the primary storage control device to the secondary storage control device is held in a write data storage portion. Update order information, including write times and sequential numbers, is managed by update order information management portions. An update control portion collects update order information from each update order information management portion, determines the time at which update of each second volume is possible, and notifies each-update portion. By this means, the stored contents of each second volume can be updated up to the time at which update is possible.
摘要翻译：本发明的存储系统即使在多个远程复制操作是异步执行时也保持存储在卷之间的内容的一致性。多个主存储控制装置和多个辅助存储控制装置通过多个路径连接，并且在相应的第一卷和第二卷之间异步地执行远程复制。将从主存储控制装置传送到副存储控制装置的写入数据保存在写入数据存储部分中。更新订单信息（包括写入时间和顺序号）由更新订单信息管理部分管理。更新控制部分从每个更新订单信息管理部分收集更新订单信息，确定可以更新每个第二卷的时间，并通知每个更新部分。通过这种方式，可以更新每个第二卷的存储内容直到可能进行更新的时间。

摘要： First and second storage apparatuses respectively and internally set a remote copy pair for copying data of a first volume to a second volume and associate a third volume with a remote copy pair according to an external command. When an I/O request to the first volume ends in an error, a host computer sends an I/O request directed to the second volume to the second storage apparatus. If the first and the second storage apparatuses detect a failure in the first or the second storage apparatus of the other side or a connection failure between the first and the second storage apparatuses, the first and the second storage apparatuses store in the third volume a failure information flag showing that the failure was detected.

摘要： A server system has servers that can be operated through switching as a primary system and a standby system, and a shared disk unit for storing data accessed by the servers. Each of the servers has a driver that acquires information on a configuration inside the shared disk unit after starting of the system. The driver sets the shared disk unit in an active state in which an access request can be sent to the shared disk unit. Access control determines whether the access request issued by an application should be sent on the basis of a management table indicating inhibited types of access requests for each access destination. The access control sends the access request to the driver when the access request is not inhibited for an access destination of the access request. By this arrangement, hot standby switching processing can be performed at high speed.
摘要翻译：服务器系统具有可以通过作为主系统和备用系统的切换操作的服务器，以及用于存储由服务器访问的数据的共享磁盘单元。每个服务器都有一个驱动程序，可以在系统启动后获取有关共享磁盘单元内部配置的信息。驱动程序将共享磁盘单元设置为可以将访问请求发送到共享磁盘单元的活动状态。访问控制确定是否应当根据指示每个访问目的地的禁止类型的访问请求的管理表来发送由应用发出的访问请求。当访问请求的访问目的地不被禁止时，访问控制向该驱动器发送访问请求。通过这种布置，可以高速进行热备用切换处理。

摘要： A first storage system misrepresents an identifier of the storage system and an identifier of a volume and provides the host computer with a first volume. A second storage system misrepresents an identifier of the storage system and an identifier of a second volume as being identical to those misrepresented by the first storage system and provides the host computer with a second volume. A management computer acquires, upon detection of a failure in an access, a status of copying, a status of the first storage system, and a status of the second storage system and controls an access from the host computer with reference to the plurality of acquired statuses. Accordingly, even when a fault occurs in one of the two storage systems, a network that connects the two storage systems, or the like, the host computer can access to latest data.

摘要： A remote copy system includes a plurality of storage systems. Each first storage system assigns a sequential number to write data received from the host and sends the write data with the sequential number to the second storage system. One of the first storage systems defers the processing of the write request received from the host and instructs each of the first storage systems to create a marker that includes a sequential number that is a marker number. The second storage systems receive the marker from the first storage system and store the marker number included in the marker.

摘要： A data management apparatus of a computer system comprises, as a retention rule for volume data, change-time identification information for identifying a point-in-time for changing a logical unit, and migration-destination unit specification information for specifying a migration-destination logical unit. An edge storage apparatus stores first identification information, which enables the identification of volume data in a logical unit, and second identification information, which enables the identification of a logical unit in a storage system after associating the first identification information and the second identification information with each other. A data management apparatus (A1) transfers the volume data from a migration-source logical unit to the migration-destination logical unit conforming to the migration-destination unit specification information subsequent to a point-in-time identified in accordance with the change-time identification information. The edge storage apparatus (B1) associates the second identification information, which enables the identification of the migration-destination logical unit, with the first identification information, and stores the associated information in a storage device.

摘要： In a system in which data employed by a computer is stored in a storage system, the storage system transfers this data to another storage system and a copy of the data is maintained in the other storage system. The consistency of the copy is maintained even when data is written, to the storage system by a computer, without having a write time applied. A source storage system, when a write time is applied to a write request, records the write time and applies this write time to the received write data and, when no write time is applied, applies the recorded write time to the received write data and transfers the write data with this write time applied thereto, to a target storage system. The target storage system stores the write data in a logical volume in the target storage system in accordance with the write time.
