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, congurable 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 rmware also uses the rebuild rate setting to control the system resource allocation for the
following tasks:
• Performing A Check Consistency
• Background Initialization. See Cancelling Background Initialization
• Full Initialization. A BIOS setting determines whether a full or fast initialization occurs. See Format, Initialize, Slow And Fast
Initialize
• Recongure. See Virtual Disk Task: Recongure (Step 1 of 3)

Resetting The Controller Conguration
Does my controller support this feature? See Supported Features.
The Reset Conguration task allows you to erase all the information on the controller so that you can perform a fresh conguration.
This operation destroys all data and virtual disks on the controller and unassigns any hot spares.
You must completely recongure the storage after performing this reset operation.
