A management apparatus, which is configured to manage at least one storage system, includes a processor and a memory. Each of the at least one storage apparatus includes a plurality of volumes, each of which stores at least one OS. The processor is configured to: determine, for each of the plurality of volumes, an OS type and version of a representative OS of the each of the plurality of volumes; select, from among the plurality of volumes, a plurality of volumes having representative OSes that share the same OS type and major version; and include the selected plurality of volumes in one deduplication group made up of volumes among which deduplication is to be executed.

Management apparatus for managing and reduplication of volumes of a storage system with respect to OS type

When shifting the condition of a pair of a main volume and a sub-volume from a split condition to a pair condition according to a request from a user, an information processing unit which can access the sub-volume is inquired whether it mounts the sub-volume or not. As a result, if a managing computer receives a notice from the information processing unit that it mounts the sub-volume, the managing computer displays a warning on its display. Thereby, data on the sub-volume can be prevented from being erased by an operation mistake of the user.

Storage system control method, storage system, information processing system, managing computer and program

A data migration management apparatus continuously monitors and stores the utilization statuses of a migration-source storage area and a migration-destination storage area, and uses the information to set up a data migration. An information management unit collects information related to the storage configuration and information related to performance from respective storage apparatuses, and stores the information in a storage unit. In a case where a data migration plan is to be set, a performance information provision unit provides, to a user computer, variations in the utilization statuses during a predetermined period for each of a migration-source volume and a migration-destination array group.

Data migration management apparatus and management method

Pairs are formed from a plurality of dispersed volumes and copying between the volumes is conducted by a series of remote operations from a management server. A management serverinstructs the generation of configuration setting filesto host computersselected so as to form copy pairs. If the configuration setting files are generated by host agents, the management serverinstructs copy start to a host computerhaving a primary volume. The host agentgenerates a prescribed command via a copy pair control moduleand causes a storage subsystemto execute copying between the volumes. When copying is completed, the management serveracquires the newest storage configuration information from the storage subsystemand updates configuration information DB

Storage system and setting method for storage configuration information

Host environment information of the host is acquired from an environment management section that manages the host environment information, a designation of a volume condition constituting a condition related to the logical volume is received from the user, a logical volume that conforms to the designated condition among a plurality of logical volumes is sought, an internal path which is a logical path in the storage system is constructed by allocating the logical volume thus found to any of the plurality of communication ports, and the acquired host environment information is allocated to at least one of the communication ports and logical volumes in the internal path thus constructed.

Access environment construction system and method

The present invention allows a pair to be formed between a plurality of discrete volumes and the progress thereof to be managed by means of a remote operation from a management server. Management serverinstructs respective host computersto generate configuration files. Next, management serverinstructs host computersto start up HORCM (Hitachi Remote Copy Module) instances. The generation of the configuration files and the startup of the HORCM instances can be separated. In one mode, configuration files are generated and the HORCM instances are started up, while, in another mode, only configuration files are generated. In yet another mode, the HORCM instances are started up when predetermined conditions are fulfilled. A more flexible operation can thus be performed.

Network storage configuration management

There are included the steps of receiving an operation input for defining a plurality of setting information pieces on a disk subsystem as a command by one operation, storing the defined setting information as a file, and sending the file to the disk subsystem.
