I recently purchases a bunch of R710's from Dell. I installed VMWare ESX on them. The installation process finishes without a problem; however once ESX boots the following error displays at the botton with red letters:

00:00:02:21.493 cpu11:4119) mod:2971: Initialization for vmfs2 failed with -1

I installed on two different servers and the same error appears.

The curious thing is that if I install ESXi 3.5 or 4 there is not problem. What does this problem mean, and how can I resolve it?
