摘要： A storage controller of a storage system performs, when failures occur in at least two drives, priority rebuilding and normal rebuilding in parallel, the priority rebuilding being performed so as to perform rebuilding using a reading drive for reading data for restoration of priority rebuild data to be preferentially rebuilt and a writing drive specified for writing the priority rebuild data restored, the normal rebuilding being performed so as to rebuilt normal rebuild data by using a specified reading drive and a specified writing drive.

摘要： A source remote copy configuration in a source storage system is migrated to a destination storage system as a destination remote copy configuration. The destination primary storage apparatus of the destination storage system defines a virtual volume mapped to the primary volume provided by the source primary storage apparatus which is a storage area of the virtual volume; takes over a first identifier of the primary volume to the virtual volume; transfers, when the virtual volume receives an access request, the access request to the source primary storage apparatus to write data in the primary volume; and takes over the first identifier from the virtual volume to another primary volume provided by the destination primary storage apparatus, after completion of copy of data from primary volume of the source primary storage apparatus into primary volume of the destination primary storage apparatus and secondary volume of the destination secondary storage apparatus.
