pNFS Device Commands

The vserver nfs pnfs devices command enables users to manage pNFS devices and their properties, including their configuration and state of the cache in the Data ONTAP kernel. A pNFS Device is a logical representation of a volume and determines how a volume is exported to the pNFS clients. pNFS clients acquire layouts on pNFS devices, which enable them to access storage via optimal network paths. A pNFS device consists of information about the device itself and mappings that enable direct network access to the storage constituents for the device. The information related to pNFS devices is visible via commands vserver nfs pnfs devices show and vserver nfs pnfs devices mappings show. All the commands implemented under this directory are for troubleshooting purposes only and users are NOT expected to execute them without the supervision of the NetApp Support personnel.
