Abstract
In remote copy systems connected with a dedicated interface, reliability is reduced for the time until the disk system that caused an error will be recovered. Therefore, when an error occurs in a primary disk system, it is replaced with a standby disk system connected to a storage area network. As a result, a remote copy system with high reliability is obtained.
