Many IAP-103s image upgrade fails (6.4 --> 6.5)

Hi,

 

We need to upgrade many IAP-103 clusters at many customers many sites, but I'm experiencing an interesting phenomenon.

 

There is an IAP-103 cluster each site, and I have experienced the error at every cluster update.

 

Not all members are running the update, and at the end of the cluster update there are always a few APs that can not update and can not come back to the cluster by this error meesage: "image version mismatch"

I checked during the update, these problematic APs didn't go over download-done state.

 

I tried to update them by disabling all APs (disable poe on the switch) and launching a single AP from the wrong ones. Since the other members were down, so she became the master, I logged in and start the upgrade. During the upgrade, I checked cli (sh upgrade info) I saw the upgrade was successful and reboot comes.

However, after reboot, he returned again with the old image (6.4.2.6), but according to the log everything is fine:

 

AP3# sh ver
Aruba Operating System Software.
ArubaOS (MODEL: 103), Version 6.4.2.6-4.1.1.6

AP uptime is 15 minutes 5 seconds
Reboot Time and Cause: AP rebooted Wed Jul 25 12:33:34 CEST 2018; Image Upgrade Successful
AP3#

 

I tired also:

upgrade-image2

upgrade from web

upgrade to many versions (6.5.4.5, 6.5.4.7, 6.5.4.8)

reset config on iap before upgrade

 

None of them works. :(

 

I need to upgrade to minimum 6.5.4.5 because of a major error fix (iap-100 series wifi driver problem)

 

What can I do with these problematic APs?

Re: Many IAP-103s image upgrade fails (6.4 --> 6.5)

How are these IAP's managed locally or via Central/AirWave? If so do you have Firmware compliance enabled? Is there any preferred masters configured?

 

As a step you could also try upgrading to the latest 6.4 then try to 6.5.

These are managed locally and there are no preferred master configured.

 

OK, I will try to upgrade first to the lastest 6.4, and I will write about expreiences.

 

Thanks!
