Abstract
Provided are a method, system, and apparatus using reliability information from multiple storage units and a parity storage unit to recover data for a failed one of the storage units. A decoding operation of the codeword is performed in each of the storage units comprising the data storage units other than the target data storage unit and the parity storage unit to produce reliability information. In response to the decoding operation failing for at least one additional failed storage unit comprising the data and/or parity storage units other than the target data storage unit that failed to decode, reliability information is obtained for the data portion of the at least one additional failed storage unit. The reliability information obtained from the storage units other than the target data storage unit is used to produce corrected data for the data unit in the target data storage unit.
