Well this has been a fun day today.
So a few weeks ago I deployed a mixed IAP225/115 cluster managed by Airwave. At first we deployed and configured some IAP225 and then when we added a few IAP115, they came up, upgraded their image from Airwave and then joined the cluster fine......all good.
Now today I was back there to carry on. A few more IAP115 were added and then all the other APs (45 or so) dissappeared. Seemingly one of the new 115 took on the role of master and wiped the config of the others and caused them to try to downgrade. :-(
None of the other ones were reachable cause I just kept getting redirected back to the 115. I couldn't even get this 115 cluster to join Airwave. Airwave itself said that the cluster was unknown or had a wrong PSK.....even though I had deleted the group, and removed then added the airwave config again.
Only after I put the downgraded image for 225 on Airwave did they start to come back, and only then did the cluster actually come back up on Airwave.
Has anyone else had experience with something like this happening? How on earth did it get into this state in the first place?
So back tomorrow to get things how they were originally. Very skeptical now about adding another 115 into the mix if it doesn't at least have the exact same firmware version. Such a shame given that it went so well a few weeks ago.
Airwave 8.0.4
IAP firmware - 6.4.0.3-4.1.0.1 (before issues)
IAP firmware - 6.3.1.1-4.0.0.1 (of 115 that was added)
