Host support for multipathing overview
ONTAP always uses Asymmetric Logical Unit Access (ALUA) for both FC and iSCSI paths. Be sure to use host configurations that support ALUA for FC and iSCSi protocols.
Beginning with ONTAP 9.5 multipath HA pair failover/giveback is supported for NVMe configurations using Asynchronous Namespace Access (ANA). In ONTAP 9.4, NVMe only supports one path from host to target. The application host needs to manage path failover to its high availability (HA) partner.
