At 0 percent, the consistency check is done only if the system is not doing anything else. At 100 percent, the consistency check has a higher priority than any other system activity.
To configure the consistency check rate using the LSI Software RAID Configuration Utility program, do the following:
Note: Using a consistency check rate of 0 or 100 percent is not recommended. The default value is 30 percent.
1.Start the LSI Software RAID Configuration Utility program. See “Starting the LSI Software RAID Configuration Utility program” on page 74.
