JacobDegeling, What I would suggest is for you to clear the hardware log, and when you can, to update the server to current. Those steps should clear up the alert. Let me know how it goes.
After deleting a Virtual Disk and then removing the physical HDDs that comprised it on one of our R730xd servers, the health light is flashing orange and my Zabbix server is telling me that there is an "Overall System Status Error". I can see errors in the server logs from when the disks were removed. I just want to tell my server that all is ok and it is not unhealthy and that it can go on living its best life. Even after rebooting the server, the orange light continues. [IMAGE] For future reference, what is the best way for one to remove physical disks so that this does not happen again?
