backups), I will lose connectivity with my Fibre Channel cards which serve up fibre channel LUNS to a VM cluster. All hell breaks loose, and then connectivity gets restored. I don’t get an error that it’s dropped, at least not on the Omnios system, but I get
notice when it’s restored (which makes no sense). I’m wondering if the cards are just overheating, and if heat sinks with a fan would help on the io chip.</span><o:p></o:p></p>
