<p>A system for input/output path switching comprises a host; a network switch coupled to the host; and a plurality of storage systems which include a first storage system and a second storage system. For switching an I/O path, from a path between the host and the first storage system via the network switch to another path between the host and the second storage system via the network switch, one of the host or the network switch changes FCID (Fibre Channel Node port identifier) information therein, to migrate a WWPN (World Wide Port Name) from association with the first storage system network interface to association with the second storage system network interface. The FCID information includes address information of storage system network interfaces of the storage systems for connecting to the network switch.</p> |
