The Set Rebuild Rate task changes the controller's rebuild rate.
During a rebuild, the complete contents of a physical disk are reconstructed. The rebuild rate, configurable between 0% and 100%, represents the percentage of the system resources dedicated to rebuilding failed physical disks. At 0%, the rebuild will have the lowest priority for the controller, will take the most time to complete, and will be 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 will be the highest priority for the controller, will minimize the rebuild time, and will be the setting with the most impact to system performance.
On the PERC 3/SC, 3/DCL, 3/DC, 3/QC, 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, 4e/Di, and CERC ATA100/4ch 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.
