    • Each communication path between controllers and a plurality of storage devices has a plurality of expanders coupled in series. In order to shorten the time during which the communication path is not used for I/O, either (A) the length of time for which I/O suppression is set for the communication path is shortened, or (B) the overall time it takes for processing other than I/O processing is shortened. In the (A), a determination as to whether or not the coupling between the expanders has been disconnected is made for the I/O-suppressed communication path, and in a case where the result of this determination is negative, a discover process is carried out after releasing the I/O suppression with respect to this communication path. In the (B), the number of command issue times of updating routing control information of the expander is reduced.
    • 控制器和多个存储设备之间的每个通信路径具有串联耦合的多个扩展器。 为了缩短通信路径不用于I / O的时间,(A)为通信路径设置I / O抑制的时间长度缩短,或(B)总时间 I / O处理以外的处理缩短。 在(A)中,关于扩展器之间的耦合是否已被断开的确定是针对I / O抑制通信路径进行的,并且在该确定的结果为否定的情况下,发现处理 在释放相对于该通信路径的I / O抑制之后进行。 在(B)中,减少了扩展器的更新路由控制信息的命令发布次数。

    • 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.
