Abstract
Systems and methods for active link verification for failover operations in a storage network are disclosed. An exemplary method includes issuing a command from a first port of a storage device to a local network device in the storage network. The method also includes receiving a response to the command at the first port of the storage device from the local network device in the storage network. The storage device fails over to a second port of the storage device if no response is received at the first port of the storage device.
