CLEAR_ERRORS controller INVALID_CACHE

Clears an invalid cache error and allows the controller and cache to resume operation.
If the error is due to an incorrectly mirrored configuration, the controller indicates
mirrored mode status after the error is cleared.
Use this command for the following situations:
When the controller or cache modules have been replaced, resulting in
mismatched data between the controllers.
When the controller or cache module is replaced while data is still in cache and
not properly flushed with the SHUTDOWN or SET NOFAILOVER commands.
