Abstract
A storage controller receives a plurality of synchronous writes from a host via a bus interface, wherein each of the synchronous writes is received for writing to a first node and a second node of the storage controller. For each record of a track written to the first node and the second node, an error detecting code is computed on writing the record. In response to determining that computed error detecting codes do not match for any corresponding records of the track in the first node and the second node, an indication of an error is transmitted from the storage controller to the host.
