OK so those are problems which are reported by the vCenter itself directly.
Open VI-client, and go there:
(vCenter Service status)
- If you have the errors there as well, that means that the problems still persist and you have to resolve them. For that, better ask at the vCenter communities forum.
- If all is green there, no errors, you can cancel those faults from within vc ops as well (there is cancel button for fault alerts).
hope that helps...
