i have installed a vsphere environment with two vsphere ESXi 5.1 hosts and a vCenter Server Appliance 5.1
Recently a strange issue has shown up. Randomly both hosts became disconnected from vCenter with the error "Cannot verify the SSL Thumbprint".
To resolve this issue i have to login into vCenter and re-verify both SSL Thumbprints and reconfigure HA, but after a random time everything happens again.
The thumbprints of both server from DCUI match the ones in vCenter.
I updated to the latest version of vCenter Appliance, 5.1 Update C, but the issue is still there.
Anyone as any idea?
Thanks a lot for your help
I was almost sure this was resolve in 5.1 but just in case you might want to try the manual fix in http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=200672... otherwise I have no idea.
