Compaq HSZ80 Array Controller ACS Version 8.3 Maintenance and Service Guide
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
