When you try to bring up CVM resource group because of the missing vxportal module your cluster service will bring resource faulted state. You can apply this action plan to fix problem.
Step 1: Check if module is loaded.
#lsmod|grep vxportal
Step 2: If not then start service.
#/etc/init.d/vxfs start or #/etc/init.d/boot.vxfs start
