Our latest purchase of Aruba access points included some that required 8.7, so we planned on upgrading from 8.5.0.3 to 8.7.1.0 over Christmas break. We have three 7220 controllers and a virtual mobility master running, with around 1200 access points.
Thursday morning, we did the upgrade on the master and the three controllers. After a reboot, around 50% of the access points failed to come back online. I figured they would take some time, as they would need to download the new code and reboot, and maybe the controllers were a little busy. By afternoon, we were still around 50%. I opened a ticket with Aruba, and they collected some logs, rebooted a bunch of stuff, but for the most part, didn't make any changes. After rebooting everything, I had around 90% of the access points up. Christmas day, I found access points dropping off of the list. They were still pingable, but the tunnels between the ap's and the controllers wouldn't fully come up. Output from show datapath sessions would show a connection, but not enough to bring the access points back. Saturday, I was back on with Aruba. After another series of log collection and reboots, we were back to around 90%. I still didn't feel good about this, as we hadn't really made any changes. By late evening, I had 9 access points online. Sunday, we moved the aruba controllers to new switches. They had previously been connected to a stack of switches, all on the same layer 2 network. After the reboot, we again had most of the access points online, but as the evening wore on, the number of access points online dropped. Monday, call Aruba, wash, rinse and repeat. At one point Monday afternoon, we had all access points back online. I don't think the engineer made any configuration changes, just rebooted the controllers. Right now, 622 are down, 607 are up. We did revert to 8.5.0.3, but that didn't seem to help. Right now, we are at 8.7.0.0.
