Configuring a Library Shared across a SAN Environment

In a SAN environment, the drives in a library can be dynamically shared between the file servers and MediaAgents.

Control of the library can be configured from the file servers and the MediaAgents. If the filer server or MediaAgent controlling the arm is unavailable, another filer server or MediaAgent can control the arm. For information about changing the active library controller, see Change the Active Library Controller.
