摘要： 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.

摘要： A controller transmits a second protocol command to a target from among one or more switch devices. The second protocol command is a command which conforms to a second protocol type in which a connection established for transmitting a command to the target is broken during processing of the command by the target, and is defined as a command corresponding to a first protocol command, which is a command conforming to a first protocol type in which the connection remains established during processing of the command by the target.

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.
