A management system manages a computer system having multiple storage apparatuses, which provide a virtual volume to a host. The computer system includes a pool, and the storage apparatus allocates a physical page in the pool to a write destination when writing to the virtual volume. The management system stores logical volume management information for managing a corresponding relationship between a storage apparatus in which a logical volume resides and a physical page forming the logical volume, and virtual volume management information for managing the corresponding relationship between a virtual segment in a virtual volume and a page allocated to the virtual segment, and based on the logical volume management information and the virtual volume management information identifies a first page migration, which is affected in a case where either a determination-target storage apparatus is stopped or a first storage area is blocked, and displays the first page migration information.

Management system and management method

An object of the present invention is to efficiently use a hierarchical pool. A management server manages performance information of multiple host computers, and based on each performance information, determines whether a prescribed host computer, which comprises a load of equal to or larger than a preconfigured prescribed threshold, exists among the multiple host computers. The management server creates a reallocation plan, which stipulates an allocation amount of a real storage area for each of multiple storage tiers, with respect to a prescribed virtual logical volume used by the prescribed host computer. Based on the reallocation plan, the management server decides a corresponding relationship between each logical storage area and each real storage area of each storage tier, and notifies a storage apparatus of this corresponding relationship.

Computer system management apparatus and management method

Configuration adjustment processing receives database configuration information and parameter adjustment policy information from an application. When database configuration information received from another application exists in DBMS, the configuration adjustment processing reads in the database configuration information and makes adjustment of the inputted database configuration information and the existing database configuration information in accordance with the parameter adjustment policy information. The configuration adjustment processing updates the existing database configuration information on the basis of the adjusted database configuration information.
