Dear all,
WLAN network was stable and running since last 2months. Due to power failure couple of times controller configuration file including all the licenses got erase. When the controller became stable I found not any license as well as no configuration. Moving on the the maintainenance page I selected the Restore flash and click restore. After that the controller reboots and my WLAN controller became stable.
NOW the controller does not respond If I am taking the backup flash. When I click on BACKUP FLASH then selecting CREATE BACKUP the controller gets hang and I am unable to access through CLI as well. I have to restart the controller and then it works fine. Again taking an action on CREATE BACKUP flash the controller gets hang.
Looking forward for the valuable response.
