To access a vFiler unit's file system using NFS and CIFS, you must prepare the vFiler unit by using the NFS and CIFS protocols, respectively.
For CIFS clients, the root of the primary storage qtree is the root (“/”) of a vFiler unit’s file system. If “/” is shared, a CIFS client mapping to it can browse all of the vFiler unit’s storage in a single tree. This mechanism is called the vFiler unit’s pseudo-root.
NFS clients must import discrete storage units as they are defined on the hosting storage systems. Pseudo-root directories are not available to NFS clients.
