Zones can be NFS clients. Version 2, version 3, and version 4 protocols are supported. For information on these NFS versions, see Features of the NFS Service in Managing Network File Systems in Oracle Solaris 11.2 .
The default version is NFS version 4. You can enable other NFS versions on a client by using one of the following methods:
You can edit /etc/default/nfs to set NFS_CLIENT_VERSMAX=number so that the zone uses the specified version by default. See Setting Up the NFS Service in Managing Network File Systems in Oracle Solaris 11.2 . Use the procedure “How to Select Different Versions of NFS on a Client by Modifying the /etc/default/nfs File” from the task map.
You can manually create a version mount. This method overrides the contents of /etc/default/nfs. See Setting Up the NFS Service in Managing Network File Systems in Oracle Solaris 11.2 . Use the procedure How to Use the Command Line to Select Different Versions of NFS on a Client from the task map.
