Publication number: 20170017403Abstract: A storage system creates an HA configuration in a virtual storage composed of resources of first and second storage subsystems. A user of the virtual storage selects a replication destination volume (second logical volume) of a first logical volume of the first storage subsystem that the user wishes to duplicate from the second storage. At this time, only a logical volume not recognized from a host is selectable as the second logical volume. When data duplication between the first logical volume and the second logical volume is started, the second storage subsystem sets an identification number of the second logical volume to be the same as the identification number of the first logical volume. Thereafter, at the point of time when duplication is completed, the second storage changes the setting of the second logical volume so that the second logical volume can be recognized from the host.Type: ApplicationFiled: June 24, 2014Publication date: January 19, 2017Inventors: Kenji SEKINE, Yutaka WATANABE, Atsushi MIYAGAKI, Nobuhito MORI, Tomohiro KAWAGUCHI
