When I see vsan healthy check Intel Volume Management Device is Unverified. So I went to the official website to upgrade the driver to solve it. But see that there are two name drivers. Are these two the same thing? If not what are they used for?
I tried search your answer and this is my guess.
Until 2.6 - the driver name is "intel-nvme-vmd", from 2.7 - driver name is "iavmd".
You can read PDFs for each version from here. (2.6 is downloadable Zip.)
