CLEAR_ERRORS INVALID_CACHE
Clears an INVALID_CACHE error and allows the controller and cache to resume
operation.
A controller presents an INVALID CACHE error during initialization if it detects a
mismatch between the cache information on the controller and the cache information on
the cache module. The controller allows only a limited set of CLI commands until you
clear the error, to prevent you from giving commands that may make the situation worse.
The
CLEAR
_
ERRORS INVALID
_
CACHE
command either clears the information in the
controller module or the information in the cache module.
