NFS won't work till I start HACMP

Oh hey, thanks!
I paste the procedures here in case someone else also needs it. So in the cookbook chapter 2.4.3 , it mentions
1. Shared volume groups that contain file systems that will be exported by NFS must have the same major number on all nodes, or the client applications will not recover on a fallover.
2. If NFS exports are defined on the node through PowerHA, all NFS exports must be controlled by PowerHA. AIX and PowerHA NFS exports cannot be mixed.
3. If a resource group has NFS exports defined, the field “file systems mounted before IP configured” must be set to true.
4. By default, a resource group that contains NFS exported file systems, will automatically be cross-mounted. This also implies that each node in the resource group will act as an NFS client, so must have a IP label on the same subnet as the service IP label for the NFS server.
BTW, the reason I still a newbie
is that this is NOT my job responsibility at all. We have some specific group people who are supposed to do this for us, but they are doing a lousy job.

nfsiod
NFSIOD(8) BSD System Manager's Manual NFSIOD(8) NAME
nfsiod -- local NFS asynchronous I/O server SYNOPSIS
nfsiod [-n num_servers] DESCRIPTION
The nfsiod utility controls the maximum number of nfsiod kernel processes which run on an NFS client machine to service asynchronous I/O requests to its server. Having nfsiod kernel processes improves performance but is not required for correct operation. The option is as follows: -n Specify how many processes are permitted to be started. Without an option, nfsiod displays the current settings. A client should allow enough number of processes to handle its maximum level of concurrency, typically four to six. If nfsiod detects that the running kernel does not include NFS support, it will attempt to load a kernel module containing NFS code, using kldload(2). If this fails, or no NFS module was available, nfsiod exits with an error. EXIT STATUS
The nfsiod utility exits 0 on success, and >0 if an error occurs. SEE ALSO
nfsstat(1), kldload(2), nfssvc(2), mountd(8), nfsd(8), rpcbind(8) HISTORY
The nfsiod utility first appeared in 4.4BSD. Starting with FreeBSD 5.0, the utility no longer starts daemons, but only serves as a vfs loader and sysctl(3) wrapper. BSD
