Which statement is true about SAN LIFs in ONTAP?

• A. SAN data LIFs cannot fail over automatically; they must be migrated manually
• B. SAN data LIFs can fail over automatically; they do not require manual migration
• C. NVMe/FC LIFs use IP addresses
• D. iSCSI uses IP addresses in a special way

Answer: (A)

SAN LIFs in ONTAP are designed to participate in automatic failover within an HA pair. When a failure affects the active SAN path or node, the SAN data LIF can move to the partner node automatically, so SAN clients (whether using iSCSI or FC) keep access to their LUNs without you having to manually migrate the LIF. This automatic failover helps minimize downtime and reduces the need for manual intervention during failovers, provided automatic failover is enabled and the LIFs are configured correctly. The other statements don’t describe how SAN LIF failover works. NVMe/FC uses Fibre Channel addressing rather than IP addresses, so LIFs for NVMe/FC aren’t defined by IP addressing in the same way as IP-based protocols. iSCSI does use IP addresses, but that detail isn’t the defining factor for SAN LIF failover behavior.
