What is LIF failover?

LIF failover refers to the automatic migration of a Logical Interface (LIF) from one network port to another. This process is vital for maintaining network connectivity in the event of a failure or disruption on the primary network port. When a network issue arises, the system can automatically switch the LIF to a secondary port without requiring human intervention, ensuring that the data services remain available and minimizing downtime.

The significance of this automatic process lies in its ability to enhance system reliability and availability. By allowing seamless transitions between ports, it ensures that client connections are maintained even during failures, contributing to overall network resilience. The LIF failover mechanism is part of the broader high availability features employed in storage systems to safeguard against single points of failure.
