摘要： A standard physical medium 1320 as loaded into library unit 1080 even in the absence of any load request from a host computer 1020 is regarded as a spare physical medium 1330 for use when the standard physical medium 1320 is under malfunction, and such medium is put in a spare media storage space 1340 while eliminating issuance of any notice to the host computer 1020. Whereby, in a computer system with redundancy configuration, it becomes possible to prevent the host computer from making use of any spare physical media.
摘要翻译：即使在没有来自主计算机1020的任何负载请求的情况下，加载到库单元1080中的标准物理介质1320被认为是当标准物理介质1320处于故障状态时使用的备用物理介质1330，并且将这样的介质放入备用介质存储空间1340，同时消除对主计算机1020的任何通知的发布。因此，在具有冗余配置的计算机系统中，可以防止主机使用任何备用物理介质。

摘要： When notice of a failover is received from a second information processing device during execution of remote copying, a second storage device requests from a first storage device first information indicating that a replication of the data written in a first storage area has not yet been transmitted to the second storage device, and that the replication of the data has not been written to a second storage area. When the first information is received from the first storage device as per the request, the second information processing device is notified that a data input/output request can be received; and, when a data read request transmitted from the second information processing device that performed failover is received, it is determined, by referring the first information, whether the target data of the data read request is stored in the first storage area.

摘要： In one aspect of the invention, A data center system comprises a plurality of data centers each including a computer and a storage system. The computers each include a memory area for storing information about an order of operating priorities among the computers and another memory area for storing a cluster service program, whereby when an active computer from the computers fails as a failed computer, the cluster service program is executed to select a standby computer from the remaining computers according to the information about the order of operating priorities to be a failover computer to take over processing from the failed computer. The information about the order of operating priorities may relate to the types of remote copy operation used between the storage systems.

摘要： An object of the present invention is to improve the usage efficiency of a storage extent in a storage system using the Allocation on Use (AOU) technique. A controller in the storage system allocates a storage extent in an actual volume to an extent in a virtual volume accessed by a host computer, detects any decrease in necessity for maintaining that allocation, and cancels the allocation of the storage extent in the actual volume to the extent in the virtual volume based on the detection result.
摘要翻译：本发明的目的是提高使用分配使用（AOU）技术的存储系统中存储范围的使用效率。存储系统中的控制器在主计算机访问的虚拟卷中分配实际卷中的存储范围，检测到维护该分配的必要性的任何降低，并且将实际卷中的存储范围的分配取消为基于检测结果在虚拟卷中的范围。
