most time to complete, and is the setting with the least impact to system
performance. A rebuild rate of 0% does not mean that the rebuild is stopped
or paused.
At 100%, the rebuild is the highest priority for the controller, minimizes the
rebuild time, and is the setting with the most impact to system performance.
On the PERC controllers, the controller firmware also uses the rebuild rate
setting to control the system resource allocation for the following tasks. For
these controllers, the rebuild rate setting applies to these tasks in the same
manner that it applies to the Rebuild task.
• Check Consistency
• Background Initialization (see Cancel Background Initialization)
• Full Initialization (A BIOS setting determines whether a full or fast
initialization occurs. See Format and Initialize; Slow and Fast Initialize.)
• Reconfigure (see Virtual Disk Task: Reconfigure (Step 1 of 3))
To change the controller’s rebuild rate:
1 Type a numerical value in the New Rebuild Rate text box. The value must
be within the 0 – 100 range.
2 Click Apply Changes . To exit and cancel your changes, click Go Back to
