Cause

This message indicates that a virtual machine has come alive on a NIC, which can happen after a virtual machine is powered on, restarted, a vMotion is performed, or when a virtual machine snapshot is created. 

Resolution

You can safely ignore this message "Uplink redundancy restored on DVPorts: "1218/77 10 0c 50 7d ## ## ##-## ## ## ## 7a b8 42 51".

This should not be confused with the message "Uplink redundancy restored on dvPorts: "dvPort1". Physical NIC vmnic1 is up", which indicates that a link is either "Up" after a "Down" event.
