Apparatus And Method For Identifying Disk Drives With Unreported Data Corruption

US Patent:
2009025, Oct 15, 2009
Filed:
Jul 31, 2008
Appl. No.:
12/183245
Inventors:
Jeffery Lawrence Shellhamer - Erie CO, US
Assignee:
DOT HILL SYSTEMS CORPORATION - Carlsbad CA
International Classification:
G06F 11/20
G06F 12/00
G06F 11/14
US Classification:
714 7, 711114, 714E11085, 714E11142, 711E12001
Abstract:
A RAID controller uses a method to identify a storage device of a redundant array of storage devices that is returning corrupt data to the RAID controller. The method includes reading data from a location of each storage device in the redundant array a first time, and detecting that at least one storage device returned corrupt data. In response to detecting corrupt data, steps are performed for each storage device in the redundant array. The steps include reading data from the location of the storage device a second time without writing to the location in between the first and second reads, comparing the data read the first and second times, and identifying the storage device as a failing storage device if the compared data has a miscompare. Finally, the method includes updating the location of each storage device to a new location and repeating the steps for the new location.
