This is the error I get when selecting the Hardware Status tab on any of our vSphere servers in vCenter. The servers were upgraded from ESX 3.5 update 4 and the hardware status was working before the upgrade.
When I connect to the vSphere servers individually through the vSphere client I can see the hardware status under configuration > hardware. The problem is only through vCenter.
I have just installed Dell OMSA 6.1 on all our hosts and this has not helpded fix the issue.
Any help on this?
