Abstract
A method and apparatus for detecting soft errors in a storage subsystem is provided. Write data generated for a write operation in a first controller is concurrently generated in a second controller and written to a storage device by the first controller. Soft errors are detected by comparing the two sets of write data by comparing respective checksums or the write data read back from the storage device by the second controller.
