Abstract:
1. A management system for managing a computer system comprising: multiple storage apparatuses, which, upon receiving a write request for a virtual volume formed of multiple virtual segments, allocate a page to a write-destination virtual segment from a pool formed of multiple pages of multiple logical volumes and write write-target data to the allocated page; and a host computer, which sends a data write request to the virtual volume, the management system comprising: a storage device; and a control device coupled to the storage device, wherein the storage device is configured to store: logical volume management information for managing, with respect to a logical volume in the computer system, a corresponding relationship between a storage apparatus in which the logical volume resides and a page forming the logical volume; and virtual volume management information for managing, with respect to the virtual volume in the computer system, the corresponding relationship between a virtual segment in the virtual volume and a page allocated to the virtual segment, wherein the control device is configured to: receive a selection of either a determination-target storage apparatus, which is regarded as a determination target from among the multiple storage apparatuses, or a first storage area, which is regarded as a determination target of a storage area formed of a page within a storage apparatus corresponding to the page; identify from among either one or multiple page migrations, which are migrations of data between pages, a first page migration, which is affected by either the determination-target storage apparatus being stopped or the first storage area being blocked, based on the logical volume management information and the virtual volume management information; and display information related to the first page migration.
