Abstract:
A host computer is coupled to a first fabric, a source storage apparatus is coupled to a second fabric, and a destination storage apparatus is coupled to a third fabric. A destination port of the destination storage apparatus comprises a same WWPN as a WWPN of a source port, and is logged in to the fabric beforehand. Duplicate WWPNs are allowed to exist because an inter fabric router separately manages the second fabric and the third fabric. When a switchover is instructed, the inter fabric router switches a coupling destination of the host computer to the destination storage apparatus.
