(3) Priority specification

For setting and displaying the priority of the Rebuild and Consistency Check for the RAID Controller, the LSI
Software RAID Configuration Utility uses numerical values while the Universal RAID Utility uses three levels of
high, middle, and low. The table below shows the correspondence between the numerical value ranges and
levels for each item.

Tips • The LSI Software RAID Configuration Utility can specify FGI (foreground
initialization) and BGI Rate (background initialization priority), but the Universal
RAID Utility cannot specify the background initialization priority.
• The Universal RAID Utility can specify the initialization priority, except for the LSI
MegaRAID. Therefore, no parameter for specifying the initialization priority is
provided on the Option tab in the RAID Viewer properties.
