"Scenarios that cause a LIF failover
LIF failover occurs in scenarios such as port failure, network interface failure, or cable failure. LIFs can be associated with failover rules that enable you to reroute the network traffic to other available ports in the cluster.
LIF failover occurs in the following scenarios:
When there is a power failure
When automatic revert is enabled on a LIF and that LIF’s home port reverts to the administrative up status
The LIF automatically migrates back to the home port.
When the port hosting a LIF is in the administrative down status
The LIFs move to another port.
When a node reboots or falls out of quorum
The LIFs on that node fail over to the ports on other nodes. If a node returns to quorum, the LIFs automatically revert to the ports on the node, provided the ports are the home ports for the LIF and automatic revert is enabled on the LIF.
For more information about quorum, see the Clustered Data ONTAP System Administration Guide for Cluster Administrators.
When automatic revert is enabled on a LIF and that LIF’s home port reverts to the administrative up status the LIF automatically migrates back to the home port."
