  • Publication number: 20210278989
    Abstract: In a case of exchanging a migration source storage controller and a migration destination storage controller sharing one storage medium during replacement of storage devices, when hardware configurations or data management forms of the storage controllers are different, data in the storage medium cannot be shared even when data management information can be copied. Accordingly, a storage system, having a storage control unit and a storage drive provided with a storage medium, includes data management information for accessing data in the storage drive. A first storage control unit copies data management information about the data in the storage drive to a second storage control unit. When a write request is received from a host after copying of the data management information begins, each of the first storage and second storage control units stores write data related to the write request in a separate storage area of the storage drive.

  • Publication number: 20210263659
    Abstract: One or more storage systems are connected to one or more storage boxes comprising multiple storage devices. Multiple storage areas provided by one or more storage boxes include an allocated area, which is a storage area that is allocated to a virtual volume, and an empty area, which is a storage area that is not allocated to any logical volume. Multiple owner rights corresponding to multiple storage areas are set in one or more storage systems. A storage system having an empty area owner right changes an empty area to the allocated area by allocating the empty area. In a case where a configuration change (a relative change in the number of storage boxes with respect to the number of storage systems) is performed, a first storage system that exists after the configuration change sets, in the first storage system, either more or fewer owner rights than the owner rights, which have been allocated to the first storage system before the configuration change.
