Abstract
To manage each channel of a system connected by multichannels every channel, an initiator has at least one I/O request queue every channel and a management queue. When the channel is extinguished, a KILL command is assigned to the management queue and transmitted to a target. A management queue agent of the target sends the KILL command to an execution agent of each queue and extinguishes the queues.
