Active IQ and AutoSupport Discussions
I came in this morning to this little gem... Anyone seen this before? I can't post auto-support because of the sensitivity of the network it resides on. I'll list below what happens:
Mon May 16 09:19:48 CDT [fci.adapter.offline:info] Fibre Channel adapter 0c is now offline.
Mon May 16 09:19:52 CDT [fci.adapter.online:info] Fibre Channel adapter 0c is now online
Mon May 16 09:21:28 CDT [fci.link.break:error] Link break detected on Fibre Channel adapter 0c.
Mon May 16 09:22:04 CDT [fci.link.error:error] Could not recover link on Fibre Channel adapter 0c after 30 seconds. Offlining the adapter.
Mon May 16 09:33:12 CDT [fci.loop.stability:info] Fibre Channel adapter 0c has a loop stability problem. 10 loop-initialization events seen in 60 seconds.
I've checked the cables and the adapter but I can't find anything on the back that stands out. These messages just keep appearing over and over..
I appreciate the help!
See The Solution
I would open a case at once.
I did experience the same error messages on a customer's side. We suspected wrong cabling first spuriously. In the end an ESH4-Module had to be replaced. This was a hardware failure.

I would advise opening a case with the NetApp support. I suspect that you may have a drive that is causing a loop reset. But with just the EMS strings it is rather hard to determine what the underlying cause may be.
We had a troublesome drive as well that was foreign and degraded. I just destroyed the volume it and zeroed it as a spare.. It was a hand-me-down disk.. Maybe that was helpful.
Ok.. All I did was reseat the ESH module and this seems to have worked.. Thank goodness for shelf multipathing!
I will still recommend to keep an eye on the counters from `fcstat link_stats` or fcstat link_stats 0c`
As you mentioned, we have reseated the ESH module. and its working fine now.
Thanks for your post !!
