Abstract
A method for auto-correction of errors in an array of disk storage devices having a plurality of disk storage devices dedicated to storing parity data to provide fault tolerance for a loss of at least two of the plurality of disk storage devices. A read operation from the storage channels transfers data to a plurality of disk channel memories. The data in the disk channel memories is checked to confirm the data is valid. Responsive to detection of invalid data, the data may be tested to identify the disk storage channel in error, including sequentially excluding data read from a different one of the plurality of disk channel memories from a parity check and determining the validity of data from remaining disk channel memories. If valid data is obtained, the disk storage channel from which the data was excluded is identified as the disk storage channel in error.
