Normal operations can go on during a rebuild, but performance may be degraded. The Rebuild Rate controls the rate at which a rebuild is performed. A high Rebuild Rate (over 50%) speeds up the rebuild, but slows system performance. A low Rebuild Rate (under 50%) slows the rebuild process, but speeds up system performance. The default setting for the Rebuild Rate is 50%. To check the Rebuild Rate from the HP NetRAID Assistant window: 1. Choose Rebuild Rate from the Adapter menu. 2. Reset the rate by dragging the slider with the mouse. 3. Click OK. 44
