摘要:
In the configuration of multiple (M units of) disk subsystems shared from multiple (N units of) hosts, having an exclusive control command that limits access to all disk subsystems temporarily is provided, using this exclusive control command, configuration information of all multiple disk subsystems, for example, performance and a setting change, are acquired in point of time series and stored in a management server database (“configuration information database”), then managed in a centralized manner, a function that associates the file that the application uses with the “configuration information database” is provided using a function that detects the position on the logical unit, and a means that can retrieve the modified contents of the system configuration and time as keys is provided in the “configuration information database”.

A storage system data duplication method for copying data of a plurality of logical volumes possessed by a first storage system to a second storage system includes the steps of: (a) copying the data of the plurality of logical volumes to the second storage system; (b) interrupting copying of the data of the plurality of logical volumes to the second storage system; (c) starting copying of data of one or more of the plurality of logical volumes to the second storage system; and starting copying of data of ones of the plurality of logical volumes other than the one or more logical volumes to the second storage system as delayed from the step (c), shortening a time taken until completion of data duplication on recreation of a group of paired logical volumes in a volume group after remote copy is temporarily stopped.

摘要:
A disk array apparatus capable of effecting saving and operation of data through a simple construction. When a host computer sets “write inhibit” or “read/write inhibit” for an LDEV which is set on a first storage device, this setting is registered in an access attribute management table and is also reflected onto a migration management table. A migration control program moves the LDEV for which access limitation has been set to a lower-speed (lower-performance) second storage device or to an external storage device. When the access limitation is released, the moved LDEV is restored to the first storage device from the storage device to which the LDEV has been moved. By performing migration control in interlocking relation to control of access attributes, it is possible to obtain a simple data saving function and data management function.

摘要:
In order to assign logical devices efficiently to logical units, a disk control system that receives a process command for writing or reading of data from an information processing device, and performs a write or read process of data with respect to a logical device corresponding to a logical unit specified by that process command, includes means for managing logical devices, which are logical storage regions that have been set in a storage region provided by a disk drive, means for storing a correspondence between logical units, which are storage regions that have been set logically, and the logical devices, and means for assigning, when a process command has been received for a logical unit to which no logical device has been assigned, a logical device to that logical unit and performing processing with regard to that logical device.
