Users Guide

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)
To Change The Rebuild Rate
To change the rebuild rate:
1 Type a numerical value in the Set New Rebuild Rate (0-100) eld. The value must be within the 0–100 range.
2 Click Apply Changes.
To exit and cancel your changes, click Return to Previous Page.
To locate Set Rebuild Rate In Storage Management
1 Expand the Storage tree object to display the controller objects.
2 Select a controller object.
3 Click Information/Conguration.
4 Select Set Rebuild Rate from the Available Tasks drop-down menu.
5 Click Execute.
You can also locate this task from the Change Controller Properties drop-down menu.
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.
CAUTION
: Resetting a conguration 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 conguration does not remove a foreign conguration. To remove a foreign conguration, select
Clear Foreign Conguration task.
NOTE: This task is not supported on PERC hardware controllers running in HBA mode.
