Yes, there is. But before trying to administrate a HACMP-cluster you should really REALLY know what you are doing. This can end up in disaster pretty fast.
In the details of of the resource groups definition (the same SMIT panel where you also state the VGs which belong to it) you can also define NFS-mounts to be part of the RG. Note, that you will need some non-NFS file system for NFS-4 mounts. (Because, unlike NFS3, NFS4 is state-aware. Locked files stay locked.)
Notice also that for NFS4 to work you need different services started, not the same as for NFS3. You also need to configure the NFS-domain before, which i suggest to be the same as the DNS-domain of the system (as this is easier to manage).
I hope this helps.

showmount
SHOWMOUNT(8) BSD System Manager's Manual SHOWMOUNT(8)
NAME
showmount -- show remote nfs mounts on host
SYNOPSIS
showmount [-a | -d] [-e] [-1] [-3] [host]
DESCRIPTION
The showmount utility shows status information about the NFS server on host. By default it prints the names of all hosts that have NFS file
systems mounted on the host. See NFS: Network File System Protocol Specification, RFC 1094, Appendix A, and NFS: Network File System Version
3 Protocol Specification, Appendix I, for a detailed description of the protocol.
The following options are available:
-a List all mount points in the form:
host:dirpath.
-d List directory paths of mount points instead of hosts.
-e Show the host's exports list.
-1 Use mount protocol Version 1, compatible with legacy servers.
-3 Ignored for backwards compatibility.
SEE ALSO
mount(8), mount_nfs(8), mountd(8)
HISTORY
The showmount utility first appeared in 4.4BSD.
BUGS
The mount daemon running on the server only has an idea of the actual mounts, since the NFS server is stateless. The showmount utility will
only display the information as accurately as the mount daemon reports it.
