One of my ESXi hosts is marked with a critical warning sign that I couldn't get rid of it. This warning sign in specif is due to a triggered alarm: Host hardware system board status. And the Severity was Critical.
This ESXi host was repurposed out of an old storage system and I knew this warning sign and the message was valid since this server had some issues with the power supply. However, I dislike seeing any kind of (red) warning signs on my dashboard and not being able to fix it. This one always coming back, no matter if you check it with an Acknowledge or Reset to Green.
First off, the action needs to be taken on the VCSA, not in the ESXi host.
- Select Configure under your VCSA. Expand More and select Alarm Definitions.
- Search for the Host hardware system board status alarm (or the one you desire to disable) and click on Disable.
- Once the alarm is disabled, you will now see your ESXi host (from the left panel) without the red warning sign, and this time, it won’t come back.
