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 11.3.
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 11.3. 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 11.3. Use the procedure How to Use the Command Line to Select Different Versions of NFS on a Client from the task map.
