Disk scrubbing is a background process performed by the array controllers to provide error detection on the drive media. Disk scrubbing detects errors and reports them to the event log.
Before disk scrubbing can run, you must enable it on the array. Disk scrubbing then runs on all volumes on the array. You can disable disk scrubbing on any volume that you do not want to have scrubbed. Later, you can re-enable disk scrubbing for any volume on which you disabled it.
The advantage of disk scrubbing is that the process can find media errors before they disrupt normal drive reads and writes. Disk scrubbing scans all volume data to verify that it can be accessed. If you enable a redundancy check, it also scans the volume redundancy data.
