3.8 Redundancy Check
A routine redundancy check allows consistencies to be detected, checked and repaired. This
prevents a rebuild from failing at the occurrence of a fault in an HDD. This is possible for
logical drives of RAID level 1, 10 or 5. The redundancy check can also repair bad sectors
detected during inconsistency check. To keep a RAID system operating stably, it is highly
recommended to routinely perform a redundancy check using the scheduling feature.
The redundancy check is executable no matter what the system load is and thus can be used in a
system environment where accesses to HDDs occur frequently.
