Using NFSv4 on AIX

For NFS v4 support, you must specify the NFSv4Root attribute. You must include vers=4 in the Option attribute of the Share resource.

Set up Enterprise Identity Mapping (EIM) in the NFS environment, if:

If either of the above points are true, and EIM is not set up, the client has minimal rights (user=nobody, group=nobody).

If you want to use the NFSv4 security feature, set the NFSSecurity attribute of the NFS resource to 1. Manually configure Kerberos or any other security environment that is supported by NFSv4.
