- ONTAP 9
- Two cluster or node management LIFs are configured on one node, and when both are enabled, ASUPs fail to send from the node hosting the two LIFs.
- In multi-node clusters, the issue may look as if ASUPs are being sent from all nodes except one
- ASUPs tend to fail for whichever node is the home node of the two mgmt LIFs.
- This sometimes occurs because the node attempts to send ASUPs using the secondary mgmt LIFs route instead of the nodes primary mgmt LIF route.
