Abstract
The present disclosure describes a system and method of performing failover in a storage area network. In one embodiment of the present disclosure, a computer network includes a host and a storage system associated with the host. The storage system has a first controller with a first port and a second controller with a second port. The first controller is assigned a common node name and the first port is assigned a first port name. The second controller is assigned a common node name and the second port is assigned a second port name. More specifically a multipathing driver is operable to determine a signal path for a communication sent to a storage device associated with the first controller and the second controller and operable to perform failover operations if the signal path fails.
