Abstract:
An embodiment of the invention is a technique to manage failover and failback. A failover of a first path is detected. The first path corresponds to a first device in a plurality of physical devices having M device types. A connection status of the first device is determined if the failover is detected. The connection status is one of a connected status and a disconnected status. The disconnected status corresponds to the failover. The first path is adjusted according to the connection status.
