    • A method of utilizing storage in a storage system comprises prioritizing a plurality of storage areas in the storage system for data recovery with different priorities; and performing data recovery of the storage system at an occurrence of a failure involving one or more of the storage areas in the storage system based on the priorities. Data recovery for one storage area having a higher priority is to occur before data recovery for another storage area having a lower priority in the storage system. In various embodiments, the prioritization is achieved by monitoring the access characteristics, or the priority is specified by the host or management computer based on the usage and/or importance of data stored in the storage system, or the priority is determined by the storage system based on the area assignment/release (i.e., usage) of thin provisioned volumes.
    • 利用存储系统中的存储的方法包括:在存储系统中对不同优先级的数据恢复进行优先级排序; 以及基于所述优先级,在所述存储系统中存在涉及存储区域的一个或多个存储区域的故障发生时执行所述存储系统的数据恢复。 具有较高优先级的一个存储区域的数据恢复将在存储系统中具有较低优先级的另一个存储区域的数据恢复之前发生。 在各种实施例中,通过监视访问特性来实现优先化,或者由主机或管理计算机基于存储在存储系统中的数据的使用和/或重要性来指定优先级,或优先级由存储系统确定 基于精简配置卷的区域分配/释放(即使用)。

    • A path is formed between a host computer and storage apparatuses without depending on the configuration of the host computer and a network and a plurality of volumes having a copy function are migrated between storage apparatuses while keeping the latest data.A computer system includes a host computer and first and second storage apparatuses, wherein the second storage apparatus virtualizes a plurality of migration source volumes as a plurality of migration destination volumes and provides them to the host computer; and if the second storage apparatus receives an input/output request for each migration destination volume, it reflects data in each migration source volume via each migration destination volume and the host computer cancels a path to each migration source volume and registers a path to each migration destination volume; and if the second storage apparatus receives a write request, it writes write data to each migration destination volume and each migration source volume and migrates copy processing control information and data until the termination of migration processing.
    • 在主计算机和存储装置之间形成路径,而不依赖于主机和网络的配置,并且具有复制功能的多个卷在保持最新数据的同时在存储装置之间迁移。 计算机系统包括主计算机和第一和第二存储装置,其中第二存储装置将多个迁移源卷虚拟化为多个迁移目的地卷并将其提供给主计算机; 并且如果第二存储装置接收到每个迁移目的地卷的输入/输出请求,则其经由每个迁移目的地卷反映每个迁移源卷中的数据,并且主机计算机取消到每个迁移源卷的路径并注册到每个迁移的路径 目的地卷; 并且如果第二存储装置接收到写请求,则向每个迁移目的地卷和每个迁移源卷写入数据,并且迁移复制处理控制信息和数据直到迁移处理结束。
