Summary page for every host is blank.

VSphere 5.5

ESX 5.0

I recently discovered every host has a blank summary page when connected to VCenter.  This occurs with the thick client or the web client.  When connecting directly to a host the summary page looks fine.  The VCenter server has been rebooted.  Does anyone have any thoughts on what could cause this?

Hi Ksooner12,

I have run into something similar and the hosts needed to have their management agents restarted.

Please give that a try and see how you go.

Note: Your VMs will not go down, but the host may appear offline in vCenter depending on how long it takes to restart the agents.

Cheers
