■ Under normal operating conditions the mirror_config policy should never be changed
to no_mirror_config . This policy option is included only as a method to correct several
unusual error conditions that might occur in the course of operation which result in a
mismatch in configuration between the two sides of a Remote Copy pair. For instance, it is
possible for a group to be created, or a volume to be added to a group, only on one side of
the pair if the operation is interrupted by a network failure. In such cases it might be
necessary to temporarily change the policy to no_mirror_config in order to bring the
configurations into alignment. After being corrected the mirror_config policy should be
immediately restored. Such operations should generally only be undertaken on the advice
of a 3PAR representative.
