I’ve had this problem for a while, and I have no way to diagnose what is going
on, but occasionally when system IO gets high (I’ve seen it happen especially
on 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.
