I just created a packaged vib that includes ipmitool 1.8.11 that can be run directly from the ESXi CLI. I needed to be able to modify fan thresholds to keep my slow-spinning fans from triggering critical alarms on my hosts. These fan thresholds aren’t exposed in the web UI and I have to modify them using ipmitool. Normally, to do this I’d have to shut down the host, and boot it up using an install of Debian on a USB stick – a bit of a pain. Why not just run ipmitool from directly within ESXi instead?
You can find the vib download, some background, installation instructions and example uses on the static page here.
