If multiple network paths are intended for NFS traffic, consider using one path for NFS control/management traffic and the remaining NFS paths for NFS data traffic. This ensures that NFS data traffic flows through the paths intended for NFS data traffic, and NFS control traffic to flow through the path intended for NFS control traffic.
When multiple dNFS paths exist for data traffic and one of the paths fail, dNFS reissues requests over any of the remaining dNFS data paths, improving database availability. Multiple data paths also provide Oracle the ability to automatically tune the paths to the NFS storage devices. Because dNFS implements multipath I/O internally, Oracle recommends not configuring LACP and channel-bonded interfaces on the database server (NFS client) for dNFS data traffic.
