Scenario 1: External IP network cable linking to NAS device fails

External network cable failure to a file server shows a scenario where the external connection to a file server fails because a cable is down (1 in the figure). Because a file server may be equipped with a hot spare and failover may occur automatically, NAS functionality may not be affected. However, the operator needs to know that the cable has failed and which devices may have been affected.

In this case, the following notifications may be generated:

• Notifications: Cable Down, IP Network Switch Interface Down, FileServer Unresponsive (in the event that failover does not happen)

• Root Cause: Interface Down

• Impact: FileServer Down
