To enable NFSv4 on your up-to-date (post VNX OE for File v7.1) VNX Unified storage system and configure a datamover to mount a filesystem to allow for NFSv4 access with a MIXED access policy, the following steps serve as a concise guide. NFSv4 cannot be done via Unisphere.
Log onto control station as nasadmin user via SSH using PuTTY.
START NFSv4 Server on VNX
server_nfs server_2 -v4 -service -start
SET DOMAIN NAME to nfsv4.domain (change as required)
server_param server_2 -facility nfsv4 -modify domain -value nfsv4.domain
LIST NFSv4 DOMAIN INFO
server_param server_2 -facility nfsv4 -info domain
LIST NFSv4 INFO
server_param server_2 -facility nfsv4 -list
MOUNT NFS_TEST_2 on server_2 for NFSv4 access
server_mount server_2 -option accesspolicy=MIXED NFS_TEST_2 /NFS_TEST_2
TRANSLATE existing, mounted NFS filesystem from NATIVE access policy to MIXED access policy
nas_fs -translate NFS_TEST_2 -access_policy start -to MIXED -from NATIVE
DISPLAY NFSv4 CLIENT CONNECTIONS
server_nfs server_2 -v4 -client -list
NFSv4 requires UNICODE enabled on DM. Check…
server_cifs server_2 | grep I18N
I18N mode = UNICODE
DISPLAY NFSv4 STATUS
server_nfs server_2 -v4
