<P>PROBLEM TO BE SOLVED: To achieve uninterrupted data migration and to balance loads. <P>SOLUTION: A system includes a first storage system, a second storage system, a plurality of switches, and a server which is connected to the first storage system through switches in a first group, and also connected to the second storage system through switches in a second group. The first storage system receives an I/O command sent from the server to a first logic unit through switches in the first group. The first storage system maintains first information associated with ports of both the first storage system and second storage system. The first information is used to achieve multipath communication between the server and first storage system, the multipath communication including at least one path passing through the second storage system and at least another path not passing through the second storage system. <P>COPYRIGHT: (C)2012,JPO&INPIT |
