Heat Sinks?<o:p></o:p> </div> </div> <o:p> </o:p> 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.<o:p></o:p> <o:p> </o:p> Mar 5 01:55:01 newstorm fct: [ID 132490 kern.notice] NOTICE: qlt2,0 LINK UP, portid 20000, topology Fabric Pt-to-Pt,speed 8G<o:p></o:p> Mar 5 01:56:26 newstorm fct: [ID 132490 kern.notice] NOTICE: qlt0,0 LINK UP, portid 20100, topology Fabric Pt-to-Pt,speed 8G<o:p></o:p> Mar 5 02:00:13 newstorm last message repeated 1 time<o:p></o:p> Mar 5 02:00:15 newstorm fct: [ID 132490 kern.notice] NOTICE: qlt3,0 LINK UP, portid 10000, topology Fabric Pt-to-Pt,speed 8G<o:p></o:p> Mar 5 02:00:15 newstorm fct: [ID 132490 kern.notice] NOTICE: qlt2,0 LINK UP, portid 20000, topology Fabric Pt-to-Pt,speed 8G<o:p></o:p> Mar 5 02:00:18 newstorm fct: [ID 132490 kern.notice] NOTICE: qlt1,0 LINK UP, portid 10100, topology Fabric Pt-to-Pt,speed 8G<o:p></o:p> </div> </body> </html>
