Invalid cache Mirrored-cache mode
discrepancy. This may
occur after you’ve
installed a new
controller. Its existing
cache module is set for
mirrored caching, but
the new controller is set
for unmirrored caching.
(It may also occur if the
new controller is set for
mirrored caching but its
existing cache module
is not.) SHOW THIS
CONTROLLER
indicates “invalid
cache.”
Spontaneous FMU
message displays:
“Cache modules
inconsistent with mirror
mode.”
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
NODESTROY
INVALID_CACHE.
Cache module may
erroneously contain
unflushed write-back
data. This may occur
after 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.
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
DESTROY
INVALID_CACHE.
