Abstract
A remote copy system includes: a host computer; a first storage system connected to the host computer; and a second storage apparatus connected to the first storage system. At least one of the first storage system and the second storage system holds, in a storage part thereof, path information used for performing a remote copy of data therebetween. The host computer references the path information in the storage part; determines whether or not a path required for conducting an operation instructed by a user exists, based on at least one of a type of the remote copy and a direction of the path; and, if the required path does not exist, displays, on a display part, that the necessary path does not exist and why the necessary path does not exist.
