Review the following information for IPv6 use:

• For IPv6 functionality for NFS, you must use NFS version 4 in order to make the mount reachable. AIX defaults to NFSv3, which does not work across IPv6. Note that NFSv4 requires several configuration steps in the operating system and NFS-related resources in VCS to enable it on the client and the exporting server.

• Note that AIX's mount command refuses to accept IP addresses unless they are resolvable to a hostname.
