no performance data avaliable after upgrade to vSphere5

[enyahe]

Hi

I've performed an upgrade of an esx environment with totallt 6 ESX hosts in 2 different clusters.

The Virtual Center is a fresh install with a new DB. Hosts where upgraded from DVD-install with "force upgrade" option.

On 2 hosts after upgrade to ESXi5 i get "no data available" in performance monitor when trying to view history like 1 day, 1 week... but the other 4 works fine. (I still can view realtime data on all hosts.) Since 4 out of 6 hosts work it feels like a host problem more than a VC/database issue.

Any ideas how to troubleshoot this?

With that said, you may try and disconnect and remove the Host(s) that are not reporting historical data from vCenter. Once removed, add the hosts back to vCenter and see if it makes a difference.
