Sun Microsystems StorageTek 6140 Administration Manual page 53

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.
