    • A computer system including a copy source volume and a copy target volume which may be selectably PAIRED or SPLIT. User management information stores: an entry indicating that a first user is permitted to effect a PAIR operation and a PATH operation; and, an entry indicating that a second user is permitted to effect a PATH operation. Operation management information indicates permitted PATH and PAIR operations in relation to each user and a volume's PAIR or SPLIT status, and stores: an entry indicating that the first user is permitted to effect the PAIR operation in which the PAIR status is PAIR, or is SPLIT WITH BACKUP DISABLED; and, an entry indicating that the second user is permitted to effect the PATH operations in which the PAIR status is SPLIT WITH BACKUP ENABLED. PAIR management information stores the PAIR status and the BACKUP ENABLED or DISABLED status.
    • 一种计算机系统,包括复制源卷和复制目标卷,其可选地配对或分页。 用户管理信息存储:指示允许第一用户执行对等操作和PATH操作的条目; 以及指示允许第二用户执行PATH操作的条目。 操作管理信息指示与每个用户相关的允许的PATH和PAIR操作以及卷的PAIR或SPLIT状态,并且存储:指示第一用户被允许实现PAIR状态为对等体的对偶操作的条目,或者是SPLIT 带备份禁用 以及指示第二用户被允许实现其中PAIR状态是SPLIT WITH BACKUP ENABLED的PATH操作的条目。 PAIR管理信息存储PAIR状态和BACKUP ENABLED或DISABLED状态。

    • A computer system comprises a storage subsystem, a host computer and a management computer, and stores catalogue information containing correspondence between a first volume for data reading or writing and a second volume for storing a copy of the data stored in the first volume. The management computer requests the storage subsystem to erase the data stored in the first volume upon reception of an erasure request of the data stored in the first volume. The storage subsystem erases the data stored in the first volume. The management computer specifies a second volume for storing the copy of the data stored in the first volume based on the catalogue information. The storage subsystem erases data stored in the specified second volume. Thus, security risks are reduced by erasing data regarding the data when the data stored in the volume is erased.
    • 计算机系统包括存储子系统,主计算机和管理计算机,并且存储包含用于数据读取或写入的第一卷之间的对应关系的目录信息和用于存储存储在第一卷中的数据的副本的第二卷。 管理计算机在接收到存储在第一卷中的数据的擦除请求时请求存储子系统擦除存储在第一卷中的数据。 存储子系统擦除存储在第一卷中的数据。 管理计算机基于目录信息指定用于存储存储在第一卷中的数据的副本的第二卷。 存储子系统擦除存储在指定的第二卷中的数据。 因此,当存储在卷中的数据被擦除时,通过擦除关于数据的数据来减少安全风险。

    • Provided is a computer system including a storage subsystem, a host computer, and a management computer for managing the storage subsystem and the host computer. The storage subsystem manages a storage extent by a group unit and creates storage extent configuration information. The management computer stores group management information, obtains the storage extent configuration information, calculates an assigned capacity for each group based on the obtained storage extent configuration information, forecasts a capacity to be assigned in the future for each group based on the calculated assigned capacity, calculates a protection term expired capacity for each group based on the group management information and the storage extent configuration information, and outputs the assigned capacity, the capacity to be assigned in the future, and the protection term expired capacity. Thus, the storage extent of the storage subsystem can easily be managed.
    • 提供了一种包括存储子系统,主计算机和用于管理存储子系统和主计算机的管理计算机的计算机系统。 存储子系统通过组单元管理存储扩展,并创建存储扩展配置信息。 管理计算机存储组管理信息,获取存储盘区配置信息,基于所获得的存储盘区配置信息计算每个组的分配容量,基于计算出的分配容量预测将来对每个组进行分配的容量, 根据组管理信息和存储范围配置信息,计算出各组的保护期限过期容量,并输出分配容量,将来分配的容量和保护期限过期容量。 因此,可以容易地管理存储子系统的存储范围。
