Which SAN LIF fails over?

iSCSI LIFs do not fail over - redundancy is provided by configuring multiple iSCSI LIFs and enabling host-side multipathing software such as Microsoft MPIO or Linux DM-Multipath.

FCoE LIFs do not support LIF failover - path redundancy for FCoE relies on multipathing at the host level, not automatic LIF migration.

Neither iSCSI nor FCoE LIFs support failover - both protocol types depend on host multipathing for path redundancy, not LIF-level failover.

FC LIFs do not support LIF failover - FC uses host-side multipathing and ALUA to manage path failures and maintain I/O continuity.

In NetApp clustered ONTAP, SAN LIFs including iSCSI, FC, and FCoE do not fail over because SAN protocols rely on host-based multipath I/O (MPIO) using ALUA or vendor-specific DSM drivers to detect and reroute around path failures. This is a fundamental architectural difference from NAS LIFs, which do support automatic failover and giveback. Configuring multiple SAN LIFs across different ports and nodes, combined with host-side multipathing, is the supported method for SAN path redundancy.
