Hi the post is not related to my issue..... Controller is booting, but will go into shell mode. The moment I take console to check the status I see my self in shell mode (shell>), once I type exit enter I see a screen with two options 1)boot controller 2rescue ..... It automatically selects 1st one and then it boots perfectly.....

I need to follow the same whenever controller reboots....until the controller boots the interfaces are not coming up.....

Take a look at the "Recovering the Wireless Controller from File System Corruption" from the Wireless Maintenance guide - https://extranet.extremenetworks.com/downloads/Pages/dms.ashx?download=5ff9760b-ae68-46fd-afbc-ffa87...

If all else fails you should contact the GTAC.
