VMware 6 ESXi Hardware Health States are not displayed (with Fujitsu CIM-Provider)

After setting up a ESXi-Cluster with VSAN based on VMware 6 the Fujitsu CIM-Providers did not provide any hardware health states and also the Fujitsu vCenter plugin did not provide any data. The service always timed out an no data where gathered. Instead the following error message was diplaed:

No new host data available. Data will be updated in 5 minutes

All that happened after updating the ESXi & FJ CIM providers with the VMware Update Manager.

After some investigation it seemed that the ESXi could not communicate with the CIM-Server. A restart of the CIM-Provider and clearing of the sensor-data and event-log seemed to fix the problem and the server was finaly able to gather data.
