If you want to temporarily remove a package, simply::

   cmhaltpkg ${pkg}
   cmdeleteconf -p ${pkg}

Using the above, the package is removed from the cluster configuration file 
yet all the set up that you've done in the package configuration directory 
still exists. To renable the package from this point::

   cd /etc/cmcluster/${pkg}
   cmapplyconf -P ${config}
   cmrunpkg ${pkg}
   cmmodpg -e ${pkg}

If you want to permanently remove a package, there's a slight bit more work 
that needs to be done. ::

   cmhaltpkg ${pkg}
   cmdeleteconf -p ${pkg}
   # Remove the exclusive bit on the volume groups:
   for vg in $(grep '^VG' ${script} | awk -F= '{print $2}')
   do
      vgchange -c n ${vg}
      vgchange -a y ${vg}
   done

If desired, remove the package configuration information from all primary 
and adoptive nodes.
