ABSTRACT:
A failed link is detected between a first SAS expander and a device. A data transfer of 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 SAS expander via the phys of the first SAS expander and the phys of the second SAS expander for inter-expander communications.
