Abstract
A technique for managing a cache in a data storage system includes creating metadata that associates cache pages with respective data objects and storing the metadata in a location accessible to a manager of the cache. Upon a failure in the cache, the cache manager checks the metadata to identify any data objects for which the cache stores dirty pages. The cache manager then coordinates with other system resources to take the identified data objects offline.
