1. Did you try adding any other vcenter (if available)?  2. Vcenter is to be added using root/ admin privilges  3. No other Vapp or Lic server running with same vcenter  4/ If above ruled out, please log a case  5. For certificate issues - open a VMware support case in parallel  thank you
IHAC using ESXI 5.5  we have deployed PowerPath/VE 5.9 SP1 P03 on the ESXi host We also installed PowerPath Management application 2.1 SP1  The issue we have is we cannot seem to add the vCenter server to the appliance as it keeps on saying there is an issue with the certificate.  PowerPath however works, as we can do rpowermt commands and register the ESXi Hosts as such.  Due to the fact the mgmt. appliance does not communicate with the vCenter server and hence not with the underlying ESXi hosts, auto registration cannot take place after an ESXi host reboot took place.  My question now is, are there any known issues or incompatibilities between the version we installed?  Many thanks in advance, Kurt Trappeniers
