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 a mirrored-cache configuration that is incorrect, 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, SET NOFAILOVER, or SET
NOMULTIBUS FAILOVER commands first.
