vVNX for VVOL - ESX IP Conflict

Hi,

I am trying to use the vVNX with vVOL to test vVols. I am trying to add vCenter but I am getting IP conflicts on the ESX hosts. As far as I can tell there are no conflicting IP addresses and everything else is working properly.

The log message isn't that helpful as it doesn't provide the IP addresses it thinks are conflicting. Is there a way to get more information from some logs or using the service account to get more information?

Thanks

Colin
