Storage system for remote copy and path selection method for remote copy

A path selection method to be performed by a storage system that is a storage system as a first storage system communicating with a second storage system and that includes a plurality of nodes, the method comprising:

• when one node or any node of two or more nodes among the plurality of nodes sends a command for remote copy in a remote copy pair to the second storage system,
• selecting, by the node, unless an abnormality related to an initiator port of the node is detected, a path connected to the initiator port;
• and
• sending the command by the node via the selected path, wherein
• there are a plurality of paths, and for each of the plurality of paths, the path is a path that communicably connects any initiator port among the plurality of initiator ports provided in the plurality of nodes and any target port among one or a plurality of target ports provided in the second storage system,
• for the one node or each of the two or more nodes, the node includes a first VOL, and
• the remote copy pair is a pair including the first VOL and a second VOL among one or a plurality of VOLs provided in the second storage system.
