I’ve got several mails and comments about this topic. It looks like that the latest ESXi 6.7 updates are causing some trouble on HPE ProLiant Gen10 servers.
I’ve blogged about recurring host hardware sensor state alarm messages some weeks ago. A customer noticed them after an update. Last week, I got the first comments under this blog post abot fan failure messages after applying the latest ESXi 6.7 updates. Then more and more customers asked me about this, because they got these messages too in their environment after applying the latest updates.
Last Saturday I tweeted my blog post to give a hint to my followers who may be experiencing the same problem.

Another customer reported FAN1 failures after applying the latest ESXi 6.7 updates on #HPE #ProLiant HW. #vExpert
Fortunately one of my followers (Thanks Markus!) pointed me to a VMware KB article with a workaround: Fan health sensors report false alarms on HPE Gen10 Servers with ESXi 6.7 (78989).
This is NOT a solution, but a workaround. Keep that in Mind.
Thanks again to Markus. Make sure to visit his awesome blog (MY CLOUD-(R)EVOLUTION) , especially if you are interested in vSphere, Veeam and automation!
