RE: Unstable cluster (or actually interconnects)

Hi,

I m Karstens collegue, and no, it is not a v serie. It is a FAS3160MC. Somewhat older system. Strange behavior started to occur after a FOS upgrade. But hey, 6.4.2 is also not the newest version.

Grtz,

Is this a v-series?

We got some major issue’s with our interconnects (or maybe ISL’s at this moment I have no idea), some background first:

We have a 3160 MC running Ontap 8.0.2 running stable for the last 3 years, however we are in the middle of upgrading to ontap 8.2 and for that we need to upgrade the FOS’s to a higher version (we came from 6.3 and we want/need to go to 7). After we upgraded the first fabric to 7.0.0b everything seemed to work fine, however later on the day we saw a lot of errors on the netapps and on the switches, by then we changed some settings that helped us in the past for these errors (port based routing instead of exchange based which would actually be the best practice following the guides) and we started upgrading the second fabric to the intermediate FOS (6.4.2) and then immediately saw the errors coming up again at which time we stopped upgrading to 7.0.0.

So long story short, we now have 2 fabrics, 1 running at 7.0.0b and one at 6.4.2b, which obviously is not recommended but we can’t do much at the moment since things are extremely unstable connection wise.

The switches themselves are set up by the best practice PDF that was available at that time, but even with the settings that changed in the meantime (basically only the portcfgfillword and I think the IOD and DLS options) we don’t see any improvements, below some snippets of the log files, the data in the snippets are continuously popping up in our logfiles. The fabrics have a single ISL (so yeah data and CI data goes through the same ISL) and we have the old DS14 ESH4 shelfs.

The weird thing is this really only happened after the FOS upgrade, we monitor all our devices quiet heavily and we haven’t seen these kind of errors in the past, both the netapp errors as well as the switch errors(brocade by the way, well yeah FOS ☺). At this time we’re kind of clueless, Netapp support doesn’t tell us much either we didn’t get much further than asking for lots of log files and reseating SFP’s which don’t seem to work and we are still waiting (and calling) for the log analysis’s.

Sorry in advance for the weird buildup of this mail but we’re making some long days at the moment ;-)

If any more info might be helpfull I can send it ;-) (but don’t want to flood the list right now).

Thanks! Karsten
