Abstract
A first storage apparatus has first and second storage control apparatuses. The first storage control apparatus includes a first port used to transmit a command for a data input/output. The second storage control apparatus has a second port used to transmit the command. The second storage apparatus has a plurality of third ports that form a plurality of communication paths with the first and second ports. The second storage apparatus executes inputs and outputs of data based on commands received from the first storage control apparatus. Based on the processing state of the inputs and outputs via a first communication path currently being used to transmit commands to the second storage apparatus, the first storage control apparatus switches the port to be used to transmit a next command to the second storage apparatus to a port belonging to a second communication path.
