6. Periodic Consistency Check
Make a periodic consistency check on array disks and correct inconsistency detected. Doing so
prevents a failure in rebuilding a failing physical drive. A consistency check must be made on the
whole Read section of the logical drive. This means that areas of the physical drives, which are not
usually accessed, are accessed all together. Thus, the consistency check command also enables
detection of an imminent physical drive failure. Making a periodic consistency check decreases the
multi-drive failure rate and maintains the steady operation of the array system.
Periodic consistency check can be performed by running Check Consistency command from the
command prompt. The command is for scheduling. When consistency check is scheduled and
performed, the running status including start, end, and at every 15 minutes is output to event log.
Requirements to execute the Check Consistency command
LSI Logic disk array controller must be connected.
Power Console Plus must be installed.
