Abstract: A management computer collects a usage condition of a volume from a host computer and a storage apparatus at each site, consolidates management thereof, and prevents a volume from duplicating among applications as a copy source. This makes it possible to select a used volume in an application as a copy source without excess or deficiency and to create a copy pair configuration definition without duplication or incompatibility. If a replication environment is constructed in a large-scale storage system, the consolidated management of a usage condition of a volume collected from the host computer and the storage apparatus at each site makes it possible to create a copy pair configuration definition by a task constituted by a plurality of applications.

Abstract: In an information system, a management server is configured to specify one or more storage areas in one or more storage systems for distributing a firmware, and to create an access control table which sets access control for permissible access to the firmware in the one or more storage areas. A plurality of servers are configured to download the firmware from the one or more storage areas by checking the access control table for permission to download the firmware, to apply the downloaded firmware if the firmware is downloaded, and to write, to the one or more storage areas from which the firmware has been downloaded, status information indicating result of applying the downloaded firmware. The management server is configured to acquire the status information from each of the one or more storage areas from which the firmware has been downloaded.

Abstract: Copy pair monitoring is provided for a storage system having plural host computers, at least one storage subsystem, and a management computer. The storage subsystem including volumes storing data requested by the host computer, the management computer being accessible to the host computer and the storage subsystem. The copy pair monitoring includes obtaining every piece of copy pair definition information that is stored in the host computer, removing duplicate copy pair definition information from the whole copy pair definition information obtained, and collecting the copy pair status based on the obtained copy pair definition information from which duplicate copy pair definition information has been removed.

Abstract: The present invention provides a backup method that makes it possible to specify the recovery-enabled time of an application even in a case where a backup has been performed without staticizing the application. In response to a first instruction from a management computer, a storage system backs up a first volume to a second volume at a first time while a first host computer continues to process an application. In response to a second instruction from the management computer, a second host computer reads out the data of the second volume and acquires a second time that is the time at which the application is recovery-enabled. The management computer stores the relationship between the backup and the second time in backup catalog information.

With this storage system and its management method, configuration information of the logical partition, to which the primary volume belongs, is sent to the secondary storage apparatus, and the configuration of the logical partition to which the secondary volume belongs is set based on the configuration information of the logical partition to which the primary volume belongs.

Abstract: The invention provides a technology applicable to technologies other than a main frame technology and monitors data recovery available time while suppressing a monitoring error within a certain range in a storage system that performs Asynchronous Remote Copy among storage devices.

Abstract: A storage system comprises multiple virtual volumes (VVOLs) and multiple pools. Each pool is configured of multiple actual area groups of different performances. The storage system accesses actual areas assigned to virtual areas identified by access commands from an access source. A controller manages pool condition information which is the information showing which actual area is assigned to which virtual area and the access load related to the virtual areas. The management system of the storage system comprises management information showing a performance requirement and a performance for each VVOL. The performance of a VVOL is the performance identified with reference to the pool condition information.

Abstract: Operation of an environment that supports both host-based replication and array-based replication is realized. According to the present invention, data in the first storage area is copied first to the second storage area using an array-based replication engine. In this case, the execution result of the replication is managed using a flag from which the copy timing can be known. In addition, data in the first storage area is copied to the third storage area using a host-based replication engine, and further, data in the third storage area is copied to the fourth storage area. Then, when data in the second storage area is restored to the first storage area, data in the fourth storage area is returned to the third storage area so that the third storage area has data of the same time as the second storage area (see FIG. 12).

Abstract: The management burden of a replication administrator is alleviated and the monitoring burden is reduced in a storage system. In a large-scale storage system configured across a plurality of sites, a management computer managing the storage system collects configuration information of a volume group such as the copy pair status information from a host computer of the respective sites including a primary site and a remote site, and analyzes the collected information. When a failure or a disaster occurs and the primary site and the remote site are switched and the management computer detects a change in the configuration of the volume group, and appropriate switches the monitoring configuration upon determining the configuration of the detected change.

Abstract: A storage management program is provided with a function of determining a suspension/continuation of a remote backup based on an operation-at-failure management table, and accomplishes the suspension/continuation of the backup based on the application in which a failure has occurred and the mode of this failure. The storage management program is also provided with a function of computing a change in the quantity of data from the last backup before the occurrence of the failure until the first backup after the occurrence of the failure, and determining the suspension/continuation of the backup, enabling to suspend/continue the backup in line with the operating status of the application.

Abstract: A storage apparatus coupled to a host device comprises a virtual volume which is a virtual logical volume configured of multiple virtual areas and a pool configured of multiple actual area groups of different performances. A controller manages pool status information which is the information showing which actual area is allocated to which virtual area and access load related to the virtual areas. A management system of the storage apparatus, with reference to the pool status information at multiple points of time from past to present and an access load threshold which is equal to or larger than 1, estimates the used capacity of each actual area group at points of time in the future, calculates the installed/removed amount of each actual area group which is the difference between the estimated used capacity and the current storage capacity, and performs the processing based on the calculated result.
