I found a great URL on how to update an ESX 3.5 VM to vSphere 4 (ESX 4) and also incorporate the new pvscsi I/O adaptor for the root drive (C: drive).

Now I just have to find it…….

Here is the link to Scott Lowe’s excellent blog…. I’m not sure if this is the exact page I read but it has the same instructions.


IMPORTANT!! VMWare do not support the pvscsi adaptor for the boot drive….they do not support it……important words…does not mean it does not work. For years, they did not support Storage Vmotion on iscsi and nfs …does not mean it did not work. You have been warned. END COMMUNICATION
