We also are not using clustering. Our initial roll out was a clustered, however, after experiencing a “very rare” STM memory leak that heavily affected users in clusters with an odd number of controllers, we moved away from that.

We upgraded from ArubaOS 8.5.0.9 to 8.6.0.6 last Sunday (12/13). No major issues so far. We have 6500+ APs (135s, 2xx, 3xx, and AP-5xx). Only one AP didn’t come back on its own but it only required a power cycle. It did take a while though. Seemed like longer than previous upgrades. Plan on at least 30 minutes of down time. We have about 50 AP-303Hs running as RAPs and they took the longest. That could probably be cut down by preloading the code on the APs. We haven’t tried that yet. We have seen some logs from our Juniper EX9208 routers about LACP timeout that were not there prior to the upgrade. Our 7240s are 2 x 10G LACP connected to them. It does not appear to be service affecting. Just annoying. It might have to do with LACP periodic fast/slow. The 7240s default to slow. The EXs default to fast. TBD… It is probably worth noting that we are not using clustering. We had some major issues with it when first looking at AOS8 and made the decision not to deploy it. We have a N+1 setup with a hot standby controller using bkup-lms-ip settings to provide redundancy.

There’s no way that I’m aware of to fix the issue if it’s already occurring. You cannot telnet into the AP remotely because the AP doesn’t have a config that could enable telnet so you must console into the AP to get access to the APboot environment and then change the os_partition to whatever partition houses the newly upgraded image.

Yep, we have an AP-205h that failed to upgrade. I think it was from 8.7.0.0 to 8.7.1.0 this fall. That AP is in quarantine space and is still broken as none of us are willing to go replace it yet. Luckily there was enough coverage from neighboring AP's, but it is less than ideal for sure. If anyone knows of a way to fix these AP's stuck in an upgrade loop without having to physically touch them, I'd love to hear how. --Dan On Fri, Dec 18, 2020 at 9:23 AM Sweetser, Frank E. <f...@wpi.edu<mailto:f...@wpi.edu>> wrote: That’s not a bad idea in general, but in this case it’s not only student housing in the midst of a COVID crisis, it’s student housing partially reserved as isolation housing for anyone who tests positive.

I really struggle with the notion of ever actually visiting deployed APs to do console work- regardless of vendor. If the bug is that bad, I’d seriously consider demanding an advance RMA for each of them. That way the site visit is a replacement rather than a tech monkeying around with file system at the top of a ladder or lift. To me, that is way beyond what should be expected of customers for what these systems cost. Just one man’s opinion.

That one stubbornly refused to fail, upgrading flawlessly every time. Has anyone ever heard if there’s a fix that doesn’t require physical access? All of my 505 are in residential space, which basically means that I’m not likely to get physical access to them until after the students move out this summer.
