[OmniOS-discuss] QLE2652 I/O Disconnect. Heat Sinks?

[Nate Smith]

I posted something about this last fall and didn’t get a response. Here was the only similar error I found. Looks like it happens on OI too.

Haven’t tried iSCSI but had similar issues with Infiniband… more frequent due to higher io load, but no console error messages.
 
This only happened on my SuperMicro server and never on my HP server… what brand are you running?

Do you see the same problem with Windows and iSCSI as an initiator? I wish there was a way to turn up debugging to figure this out.

Same problem here… have noticed I can cause this easily by using Windows as initiator… I cannot cause this using VMware as initiator… 
No idea how to fix, but a big problem.
Br,

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.
