PROBLEM TO BE SOLVED: To provide a method for providing path failover for multiple SAS expanders operating as a single SAS expander. SOLUTION: A failed link is detected between a first SAS expander and a device. A data transfer by the first SAS expander connected to the device via the failed link is re-routed to a second SAS expander connected to the device via a functional link. The first SAS expander is connected to the second SAS expander via the physical port of the first SAS expander and the physical port of the second SAS expander respectively for inter-expander communications.
