US 11,080,149 B2 · Restore current version of a track from a non-volatile storage into a new location in cache

Abstract

Provided are a computer program product, system, and method for restoring tracks in cache. A restore operation is initiated to restore a track in the cache from a non-volatile storage to which tracks in the cache are backed-up. The non-volatile storage includes a current version of the track and wherein a previous version of the track subject to the restore operation is stored in a first location in the cache. A second location in the cache is allocated for the current version of the track to restore from the non-volatile storage. The data for the current version of the track is transferred from the non-volatile storage to the second location in the cache. Data for the track is merged from the second location into the first location in the cache to complete restoring to the current version of the track in the first location from the non-volatile storage.
