Set Rebuild Rate

Dell OpenManage™ Storage Management User's Guide

The Set Rebuild Rate task changes the controller's rebuild rate.

During a rebuild, the complete contents of an array disk are reconstructed. The rebuild rate, configurable between 0% and 100%, represents the percentage of the system resources dedicated to rebuilding failed array 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 at the highest priority for the controller, will minimize the rebuild time, and will be the setting with the most impact to system performance.

Note: On the PERC 2/SC, 2/DC, 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 Check Consistency and Background Initialization tasks. The rebuild rate setting applies to these tasks in the same manner that it applies to the Rebuild task.

To change the controller's rebuild rate:

1. Type a numerical value in the Rebuild Rate text box. The value must be within the 0 - 100 range.
   
   
2. Click Apply Changes. If you wish to exit and cancel your changes, click Go Back To Controller Information Page.
   
   

To locate this task in Storage Management:

1. Expand the Storage tree object to display the controller objects.
   
   
2. Select a controller object.
   
   
3. Select the Information/Configuration subtab.
   
   
4. Select Set Rebuild Rate from the Available Tasks drop-down menu.
   
   
5. Click Execute.
