A computer implemented method, apparatus, and computer usable code for managing cache information in a logical partitioned data processing system. A determination is made as to whether a unique identifier in a tag associated with a cache entry in a cache matches a previous unique identifier for a currently executing partition in the logical partitioned data processing system when the cache entry is selected for removal from the cache, and saves the tag in a storage device if the partition identifier in the tag matches the previous unique identifier.
