Hi, For so far as I know SAN is used to transfer data, LAN is used for communicating between TSM server(s)/Agents. So, if there is a problem in your LAN configuration the communication between Server(s)/Agent can be interrupted. It happend in our case a couple of times. After some investigation it turn out to be a hardware problem on a switch port.
