NFS client Mount script after boot

Hi,

I have 12 AIX P series servers. One has the NFS DB2data and the others are client mounts. NFS is not in /etc/filesystem because if NFS DB2data not up the client takes 7+ minutes to give up on nfsmnt and boot up.
I'd like to check that nfs is up, then do the client mount all from a startup
script. Any suggestions? Or forseen problems?
