My environment is ESX 3.5 Update 5 and VI 2.5.
I permanently find all templates on several ESX hosts displayed as disconnected.
I tried three ways suggested in discussions and in VMWare KB:
service vmware-vpxa restart
service mgmt-vmware restart
VirtualCenter Server service restart
These services restart helps but only for a couple of hours and templates get disconnected again.
I can't restart ESX servers because they hosts important production VMs.
Is there any way to fix root cause of this issue and prevent disconnections in future?
Waiting for any suggestions...
I've tried to update vCenter Server from U2 to U6 and that did the trick. My templaes stay connected for several days which never occured before.
There was a fix in U5 which affected session between vCenter and ESX timeout and I guess helped with templates.
