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 has the lowest priority for the controller, takes the 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 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, and 4e/Di 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.
l Check Consistency
l Background Initialization (see Cancel Background Initialization)
l Full Initialization (A BIOS setting determines whether a full or fast initialization occurs. See Format and Initialize; Slow and Fast Initialize.)
l 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 Previous Page.

Reset Configuration

Does my controller support this feature? See Supported Features.
Use the Reset Configuration task to erase all information on the controller so that you can perform a fresh configuration. This operation destroys all data and
virtual disks on the controller and unassigns any hot spares.
You must completely reconfigure your storage after performing this operation.


To reset the controller configuration:

1. Review the virtual disks that is destroyed by resetting the controller configuration. Make backups as necessary. Click Blink at the bottom of the screen
to blink the physical disks included in the virtual disks.

2. Click Reset Configuration when you are ready to erase all information on the controller. To exit without resetting the controller configuration, click Go
Back to Previous Page.

CAUTION: Resetting a configuration permanently destroys all data on all virtual disks attached to the controller. If the system or boot partition
resides on these virtual disks, it is destroyed.
NOTE: Resetting the controller configuration does not remove a foreign configuration. To remove a foreign configuration, use the Clear Foreign
Configuration task.
