ONTAP 9.14

to Japanese version

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.

Multipath HA pair failover/giveback is supported for NVMe configurations using Asynchronous Namespace Access (ANA). he application host needs to manage path failover to its high availability (HA) partner.

For information about which specific host configurations support ALUA or ANA, contact Fujitsu support personnel for your host operating system.
