The Sun StorEdge Disk Scrubber checks the integrity of an array's media. For the storage pools configured on these arrays, it also checks the RAID parity data. The disk scrubber continuously scans disk drives for media errors. When an error is detected, it reports the problem and attempts to fix it. This paper provides an overview of disk scrubbing in general as well as a description of Sun's implementation of disk scrubbing. In addition, this paper describes various types of disk drive failures and shows how the disk scrubber can reduce the likelihood of such failures.
