Stage: PROBLEM TO BE SOLVED: To suppress a decrease in performance of remote copy performed between a second storage system and a first storage system composed of a plurality of nodes.SOLUTION: For each of a plurality of paths between a first storage system and a second storage system, the path communicatively connects any one of initiator ports of the first storage system and any one of target ports of the second storage system. The node has a first VOL that configures a remote copy pair with a second VOL in the second storage system. When the node transmits a command for remote copying in the remote copy pair to the second storage system, the node selects a path connected to the initiator port of the node, and transmits the command via the selected path, unless an abnormality is detected in the initiator port of the node.SELECTED DRAWING: Figure 1 (Grant)
