Setting The Rebuild Rate

Does my controller support this feature? See Supported Features.

The Set Rebuild Rate task allows you to change the rebuild rate for a controller.

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 for rebuilding failed physical disks. At 0%, the rebuild has the lowest priority

for the controller, takes the maximum 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:

• Performing A Check Consistency
