SMVI Snapshot fails on RDM LUNS

I did a recent NetApp deployment where SMVI was installed. Snapshot's would work for every virtual machine except for the ones that were using RDM luns. There are several NetApp and VMware articles and KB's out there that states this is the way to go now for mounting Exchange, SQL, etc to virtual guests. After some troubleshooting I was able to determine that I was unable to take a snapshot just using VMware. After uninstalling the VMware tools and reinstalling without the VSS driver component it started working.
