Abstract
A technique for operating a data storage system includes generating information that identifies data that is currently stored in a write cache of the data storage system. The information is stored in a data structure associated with the data storage system. In response to a failure of the data storage system, the information in the data structure is accessed to identify the data that was lost in the failure.
