Metadata track selection switching in a data storage system
Metadata logic switches selection of a metadata track from multiple available metadata tracks in a volatile cache to fill the selected metadata track in a metadata track selection interval with metadata entries as source tracks of a source volume are copied to a backup volume of a copy relationship. Destage logic destages to storage a deselected metadata track containing metadata entries generated in a prior metadata track selection interval, while the metadata logic continues to generate and fill additional metadata entries in the selected metadata track in a concurrent metadata track selection interval. Other features and aspects may be realized, depending upon the particular application.
