Figured it out, it was related to the iSCSI addresses.
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. [IMAGE]  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
