if the new controller is set
for mirrored caching but
its existing cache module
is not.)

erroneously contain
unflushed write-back data.

you’ve installed a new
controller. Its existing
cache module may
indicate that it contains
unflushed write-back data,
but the new controller
expects to find no data in
the existing cache module.
(This error may also occur
if you install a new cache
module for a controller that
expects write-back data in
the cache.)
SHOW THIS CONTROLLER
indicates “invalid cache.”
No spontaneous FMU
message.
