Recovering the Wireless Controller from File System Corruption

A power outage can, in rare cases cause file system corruption to the wireless controller. If file system
corruption occurs, the controller might not be able to start up and provide service. This section
describes how to recover the controller in such a situation.
To Recover the controller from File System Corruption:
1 Connect to the console port. Do not use the ESA ports or the Admin port. For more information, see
Using the Console Port
2 Monitor the console output of the system startup. In case there are file system corruptions, you will
see similar output containing unexpected file system inconsistency with a request for the manual
actions.
