Zone director 3000 started cold rebooting continuously after upgrade the firmware 9.8.2

unknown

Hi
Zone director 3000 (50 Ap's licensed) which running fine with the firmware 9.7.2, with the Ap's ZF7962 - 6No's & ZF7982 - 14 No's, we had recently purchased the additional R700 Ap's.
Since the R700 Ap's support only from the 9.8.1 firmware, we had upgraded the WiFi Controller (ZD-3000) to 9.8.2., the firmware was upgraded successfully, after 5 min the Zone director 3000 started cold rebooting continuously & we were unable to access the controller through WEB & CLI,
Even i tried by remove the power & waited for 5 min, the power on the Controller, it was accessible only for 3-5 min, after that we were not able to access the controller through WEB & CLI,

Can some one please help us what exactly the issue,

Hi,
Just a few questions:
1) Are you sure you followed the path when you upgrade the firmware? Because it looks like incorrect upgrade path. This is I faced before.
2) Did you do a backup when you upgrade? Have you tried hard reset?

Hi

Thank you for the replay

1) i'm not able to get what path you are talking about,
Just i downloaded the firmware from the ruckus site (zd3k_9.8.2.0.15.ap_9.8.2.0.15.img) & login in to the controller through web ->Administer tab->upgrade->Software Upgrade i clicked on the Choose file then did the upgrade.
hope this the right way to do it, Please suggest.

2) yes i took a Configuration backup before upgrade the controller & also i tried with resting the controller to factory default & loading the configuration,

Still it's the same issue.

your path is correct. •9.7.2.0.9 (9.7 MR2) to 9.8.2 is fine.

from 9.8.2 release notes:

4.1. ZoneDirector
4.1.1. Official 9.8.2 upgrade paths supported:
•9.6.0.0.267 (9.6 GA)
•9.6.1.0.15 (9.6 MR1)
•9.6.2.0.13 (9.6 MR2)
•9.7.0.0.220 (9.7 GA)
•9.7.1.0.32 (9.7 MR1)
•9.7.2.0.9 (9.7 MR2)
•9.8.0.0.369/373 (9.8 GA)
•9.8.1.0.99/101 (9.8 MR1)
If you are running an earlier version, you must first upgrade to one of the above before upgrading to 9.8.2.

I suggest that you remove the controller from network. reboot it. see if controller comes up does it continue to reboot it...

just chking to see if new AP are triggering this or not...

btw - if you are able to login, please collect controller debug file and open a case with support.

Hi

The Controller work fine & it never reboot if i remove from the Network,
Also i added only R-700 Ap's still it was working fine, the problem is repeating only when i bring all the ZF7982 Ap's in to production.

i "think" one or more AP is sending a corrupt packet to controller which is causing the controller to reboot.

You should work with support to get it fixed. in the meantime, just re-upgrade your controller to same firmware and see if it helps.

Reduce ZD overhead by disabling Real Time Monitoring, Packet Inspection Filter, and/or Application Recognition on your WLANs.

To help with troubleshooting, on your Administer/Diagnostics page, check the "Access Points" debug component,
and if you have problems with all APs connected to the network again, open a ticket with Support and
provide your ZD debug info file for their deeper inspection.

I Found a issue with one of the AP, this particular AP was going offline intermediately,
I have removed this AP from the network, now everything looks fine & issue has been resolved.
