Ok, I just double checked. I misspoke. The MS HW Agent is an add-on from MS which accesses our IPMI stack to provide Cyclops health (same as BMC/DRAC) – available through WMI only.
It looks like you have OMSA 6.1 . One suggestion is to update to OM 6.5 (current) as I recall some trouble with OMSA and the BMC status some time back.
Installed 6.5 last night a rebooted. Still showing the yellow warning triangle on the MS Hardware Agent. Any idea what that piece of software is called? How it can be updated? Or at least diagnosed?
I went and checked the Microsoft IPMI driver. The driver itself is reporting that it's operating fine in device manager. Is there any way to figure out what this thing is reading that OMSA isn't? Everything else looks fine in OMSA give a green check mark. I tried removing the driver, which removes the hardware agent from the Agent Status pane, but the driver is reinstalled when the server reboots.
