(3) Priority specification
For setting and displaying the priority of the background tasks (Rebuild, Patrol Read, and Consistency Check)
for the RAID controller, the WebBIOS 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. In this case, the priority is the percentage of the background task processing to all
processes being processed by the RAID controller.
• Correspondence between the setting values for the WebBIOS and the display levels for the Universal

Tips
• The WebBIOS can specify the background initialization priority, but the Universal
RAID Utility cannot.
• Although the Universal RAID Utility can specify the priority of initialization (Slow
Initialize), this server does not support this function.
