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 COPY=
commands.
