摘要： A storage device includes a plurality of expanders connected to a disk device and a controller unit for controlling the expanders. The disk device stores data transmitted from a host device. The controller determines whether, when download data is received from a predetermined terminal to update firmware of an expander, it is necessary to initialize a corresponding expander after downloading the download data by the expander, transmits determined initialization determining information determined to the terminal, transmits the download data to the corresponding expander, and instructs the corresponding expander to update the firmware at a timing for updating the firmware, which is determined by the terminal based on the initialization determining information.

摘要： Upon receiving a primary/secondary switching command from a secondary host system, a secondary storage control device interrogates a primary storage control device as to whether or not yet to be transferred data that has not been remote copied from the primary storage control device to the secondary storage control device is present. In the event that yet to be transferred data is present, the secondary storage control device receives yet to be transferred data from the primary storage control device and updates a secondary volume. The primary storage control device then manages positions of updates to the primary volume due to host accesses to the primary volume occurring at the time of the secondary storage control device receiving the primary/secondary switching command onwards using a differential bitmap table.

摘要： A disk array system having first and second housings and a controller for controlling the first and second housings. Fiber channel hard disk drives are received in the first housing, and serial ATA hard disk drives are received in the second housing. When reading data stored in a serial ATA hard disk drive in the second housing, the controller reads a plurality of pieces of data including the data to be read and parity data for the plurality of pieces of data from all the hard disk drives of an RAID group to which the hard disk drive storing the data to be read belongs. Thus, the controller examines whether the plurality of pieces of data including the data to be read are written in the hard disk drives with erroneous contents or not.
