Thank you for your detailed response. Sorry for my delay in getting back to you.
I followed your instructions for listing the hosts and host MACs. It looks like all the data was actually still there.
251 host MACs
I removed the hosts and MACs anyway since I have a pretty recent exported host list. After removing them I returned to the web interface and saw that there was one pending host listed on the host management screen. This was the first time since updating that I’ve had any host information appear here.
So with the hosts and host MACs all removed, client machines are trying to register and successfully appearing as pending hosts.
I imported my host csv and successfully imported 189 hosts, however as soon as the import was done the host list appeared blank again just like in my previous snapshot.
Is my host data itself causing the issue?
I looked at the CSV and the entries are pretty varied. Perhaps I should clean it up more before uploading?
I don’t have a problem sharing it through a private message if you would like.
