ESXi 5.0U2 marked as Unknown

Hi,

I'm using the 1.1.1 patched OME trying to get my ESXi 5.0U2 hosts inventoried. I've installed OM-SrvAdmin-Dell-Web-7.1.0-5304.VIB-ESX50i_A00. I followed the install directions, but UserVars.CIMoemProviders doesn't exist on my hosts--but a UserVars.CIMvmw_OpenManageProviderEnabled does and it's set to 1.

OME shows the hostname properly, Device Type as "unclassified" and Health Status as "?".

Ideas?

Thanks
