Cache module can
erroneously contain
unflushed writeback
data. This can occur
after installing a new
controller. The
existing cache
module might
indicate that the
cache module
contains unflushed
writeback data, but
the new controller
expects to find no
data in the existing
cache module.
This error can also
occur if installing a
new cache module
for a controller that
expects writeback
data in the cache.
SHOW
THIS_CONTROLLER
indicates invalid cache.
No spontaneous
FMU
message.
Connect a terminal to the
maintenance port on the
controller reporting the
error, and clear the error
with the following
command—all on one
line: CLEAR_ERRORS
THIS_CONTROLLER
INVALID_CACHE
DESTROY_UNFLUSHED_
DATA. Refer to the
controller CLI reference
guide for more
information.
