Absolutely!
Right now i don't have a HACMP-system at hand to check the details myself, but: yes, that is (still) possible and in fact is the recommended way to do it.
Mounts will be done by a sort-of start/stop-Script HACMP provides for itself, its name is "clas-nfsv4" or something similar (again, i can't check and am working from memory) which will be entered automatically when you configure an NFS-mount and/or -export. I am not sure if one can configure the order in which this and your own application-server is called but if you want to be perfectly sure configure the NFS-services in its own RG, then configure a start before/stop after-dependency with your application RG.
I hope this helps.
