In other words: Your Solaris-Cluster is not editing your /etc/exports file in case of a Veritas-Takeover.
Change the rsh command
"exportfs -i -o " to "exportfs -p"
and the /etc/exports file will be changed automatically and thus the overtaking filer will find the right, current export settings. This should solve your requirement.
