For a NAS data LIF to return automatically to its available home port after startup or recovery, the -auto-revert setting must be enabled (true). The home-port setting identifies the preferred destination but does not itself enable automatic reversion.
NetApp ONTAP assigns every logical interface (LIF) a defined -home-node and -home-port during creation, representing its optimal, permanent physical network location. During an unplanned node outage or reboot, NAS data LIFs automatically migrate to healthy surviving ports on partner nodes defined within their failover group to maintain continuous client connectivity. Once the rebooted node completes its startup sequence, passes hardware checks, and rejoins the cluster, the NAS data LIFs must migrate back to their original physical interfaces. When -auto-revert is set to true, ONTAP constantly monitors home port availability; as soon as the home node and port transition to the operational "up" state, ONTAP automatically migrates the LIF back home without administrative intervention. If -auto-revert is set to false, the LIF remains on the failover port indefinitely until manually reverted.
