  • Publication number: 20120221729
    Abstract: Even when a configuration in which instances of plural kinds of storage management software having equivalent functions are arranged to cooperatively manage a large-scale storage system is adopted, to prevent occurrence of a management inoperability and configuration information inconsistency and enable the same management operation and information reference as those performed when all management target objects are managed by a single instance. In the present invention, a representative management computer serving as a representative among management computers is determined. The representative management computer collects, from storage apparatuses and host computers, information concerning the management target objects and configuration summary information including a relation type among the objects and determines, on the basis of the configuration summary information, management target objects which each of the management computers should take charge of.

  • Publication number: 20120215895
    Abstract: Provided is a technique capable of efficient comprehensive management of a system, even if the system is a large-scale storage system. Management software acquires configuration information of a storage system (computer system) in two stages. In a first stage, the management software acquires only basic information of resources (identifiers of resources, the number of resources, and relationship between the resources) included in storage subsystems, host computers, switches, hubs, and the like. The management software determines a range and timing of acquiring detailed configuration information and necessity of holding the detailed configuration information based on the acquired basic information. In a second stage, the management software acquires the detailed configuration information of an appropriate range at appropriate timing. The management software always holds the basic information, but holds the detailed information only necessary to hold.

  • Patent number: 8024603
    Abstract: The invention is directed to a storage system including a storage subsystem providing a data storage service to a host computer, and a management device managing the storage subsystem. The management device issues a command to a controller in the storage subsystem for migrating data on a migration-source volume to a migration-destination volume in accordance with a predetermined task. When the migration-destination volume is not available for use for some reason, and when the data migration is not completed normally, the management device searches an alternative volume in accordance with migration-destination requirements including essential and arbitrary requirements, and then issues a command for data migration to thus found alternative volume. With such a configuration, even if a migration-destination volume is not available for use for some reason during data migration, any other volume can be used as a migration destination in accordance with the migration-destination requirement(s).

  • Publication number: 20110225117
    Abstract: A storage system includes a plurality of types of media and a controller, provides a plurality of logical volumes, and performs a reallocation process for migrating data specified in accordance with a reallocation policy from media in which this data is stored to media of different types from the media. A management system searches for a logical volume that conforms to a migration policy, which is a condition under which the reallocation process is considered ineffective, from a reallocation group, which is a group of one or more logical volumes subjected to a target of a reallocation process, and causes the storage system to transfer data in the logical volume that is discovered to outside of the reallocation group.

  • Publication number: 20110082988
    Abstract: In recent years reducing the operating cost of storage devices (hereafter, also referred to as storage sub-systems) has been an important task for the management of storage systems. As one method for solving this task, data life cycle management, in which data is relocated from, for example, a new storage sub-system to an older storage sub-system in accordance with how new the data is or the frequency of use of the data, has become important. One technology for achieving data life cycle management is technology for migrating the contents of a storage area (hereafter referred to as “volume”) of a storage sub-system to another volume without affecting the host computer that uses the volume. In the present invention, when an associated source volume (for example, the source volume in a copy pair association) of a pair of associated volumes (or groups) is migrated, migration of an associated destination volume (for example, the target volume in the copy pair association) is also controlled.

  • Publication number: 20100223442
    Abstract: Provided is a computer system for identifying all physical resources which have been allocated to logical units before to be subject to shredding and for performing shredding on the identified physical resources. All the physical resources related to the physical resources specified by a user to be subject to data erasing are selected using usage history for the storage system. Moreover, a shredding task for the selected physical resources is generated according to configuration information of the storage system and shredding is performed based on the generated task. Consequently, the data is completely erased.

  • Publication number: 20100057989
    Abstract: A data storage system satisfying user's requirements of a thin provisioned volume even if an event has occurred in which the requirements of the thin provisioned volume are not satisfied. When event information is sent from a storage subsystem to an administrative computer, the computer identifies physical resources affected by the event. A decision is made as to whether the identified physical resources satisfy the pool requirements of the thin provisioned volume. If the pool requirements are not satisfied, physical resources satisfying the pool requirements are selected from all physical resources. The administrative computer instructs the storage subsystem to move data. The storage subsystem moves data stored in physical resources affected by the event to physical resources satisfying the pool requirements and modifies the physical resource numbers given to the physical resources affected by the event to the physical resource numbers given to the physical resources satisfying the pool requirements.

  • Publication number: 20090119529
    Abstract: This invention provides, when optimizing a configuration of a storage system using a pool, an optimal configuration while ensuring a policy set by an administrator, the policy concerning a power saving performance, a response performance, or the like. The management computer sets, according to the set policy, priorities to volumes held by a storage subsystem, and reserves volumes satisfying the capacity of the pool, in descending order of the priority. Only some of the reserved volumes are registered for the pool in descending order of the priority. At this time, it can be guaranteed that a host computer makes no access to the volumes which have not been registered for the pool, and therefore the sleep state is set to physical drives forming the volumes or to a controller controlling the physical drives.
