Applies to

Upgrades from versions earlier than ONTAP 9.13.1 to later versions

Answer

  • In ONTAP 9.13.1 and later, a feature has been added for checking L2 Reachability status.
  • This can cause native or untagged ports to become degraded and result in LIF revert failure during upgrade. 
  • In such cases, proceed with ANDU pauses due to data LIF migration error for the fix.
