I'm pretty sure what's going wrong here... Since CSM manages shared storage, and shared storage cannot safely be managed without ha, it refuses to do anything is ha isn't loaded. It probably doesn't detect your plug-in and since ha isn't loaded, it refuses to start.
I'm not very good a C programming but I'll take a quick look in the CSM plug-in code to see what I could do. Thanks for the help...
