But after I start HACMP (smitty clstart), all NFS services become active automaticlly.

Why is that ?

BTW, my /etc/exports is rather simple, something like

/share -anon=500,sec=sys:krb5p:krb5i:krb5：dh,rw

Because of the HACMP design. HACMP does not expect you to have exports beside the cluster resources. Using both the AIX /etc/exports and the Cluster /usr/es/sbin/cluster/etc/exports is a (well known) possible source for cluster failure i.e. bad administration. Without the activated Resource Group there should be nothing of interest on the cluster node. So do not use a non-service IP-address or a persistent address for NFS exports. You should use a Service Label for the NFS export and let HACMP handle when/where to export the FS.
