摘要： A storage subsystem that has detected the necessity of the data relocation determines whether the data relocation is possible or not from one storage unit to another within the particular storage subsystem. A virtualization device is notified in the case where the data relocation in the particular subsystem is impossible. The manager of the virtualization device gives an inquiry to the storage subsystems as to whether any one of them can become a relocation destination or not. A storage subsystem determines, based on the related information, whether the data relocation requested is possible or not within the particular storage subsystem. In the case where such a relocation is possible, the copying process is carried out for data relocation from one storage subsystem to another in compliance with an instruction from the virtualization device.

摘要： With the migration of a logical volume between virtualization apparatuses, there has been a need to change the setting of a host computer in order to access a migration destination logical volume. In a control method for a computer system including a host computer, one or more storage systems, and plural virtualization apparatuses, a first virtualization apparatus includes a first memory and manages a first logical volume to which the host computer issues an access request, and a second virtualization apparatus includes a second memory and manages a second logical volume to which the host computer issues an access request, wherein the control method associates a first real storage area on the storage system, which has been associated with the first logical volume, with the second logical volume, and stores, in the second memory, first identification information that uniquely identifies the first logical volume within the computer system.

摘要： When data in the first primary volume is migrated to the second primary volume, an access request from the host to the primary volume is transferred to the second primary volume. Further, the second storage system stores write data received from the host and data of the first primary volume received from the storage system, into the second primary volume. Out of data stored in the second primary volume, the second storage system sends data determined by management information received from the first storage system, to the third storage system.
摘要翻译：当第一个主卷中的数据迁移到第二个主卷时，从主机到主卷的访问请求将传输到第二个主卷。此外，第二存储系统将从主机接收的写入数据和从存储系统接收的第一主卷的数据存储到第二主卷中。从存储在第二主卷中的数据中，第二存储系统将由从第一存储系统接收的管理信息确定的数据发送到第三存储系统。

摘要： An arbitrary number of a plurality of physical devices are mapped to each logical device provided for a host as a working unit, while considering a priority given to each logical device, and with each physical device being made up of a plurality of disk devices. This arrangement allows dirty data to be quickly saved to the disk devices in the order of logical device priority in the event of a failure. Furthermore, jobs are preferentially processed for important tasks in the event of a failure to reduce deterioration of the host processing performance.

摘要： The storage system is coupled to a computer and includes a plurality of physical storages being used to configure a first logical storage and a second logical storage, a control unit receiving a read request and a write request from the computer; and a cache memory storing data which is sent to the computer. The control unit determines whether a request from the computer is a write request or a read request. If it is a read request, the control unit reads data from the cache memory or at least one of the plurality of physical storages based on the read request. If it is a write request, the control unit determines whether destination of the write request is the first logical storage.

摘要： Provided is a storage system capable of starting/stopping a disk drive. At the time of allocating a logical device, it is judged, based on attributes including a purpose of the logical device, whether or not control can be performed in terms of start/stop of an allocation target disk drive to determine an allocation destination disk drive. Further, in the case where access to a specific logical device is stopped due to release of a path definition or other such cause, it is judged whether or not a disk drive corresponding to the logical device can be stopped. When it is judged that the disk drive can be stopped, the disk drive is stopped. When it is judged that the disk drive cannot be stopped, the logical device is migrated to another disk drive that can be stopped, a migration destination disk drive is stopped.
