Abstract
Provided are a computer program product, system, and method for using a transient cache list and prolonged cache list to manage tracks in cache based on a demotion hint with a track access request. A track is staged into the cache in response to a request for the track. A determination is made as to whether the request provides a demotion hint. The track is indicated in a transient cache list in response to determining that the request provides the demotion hint. The track is indicated in a prolonged cache list in response to determining that the request does not provide the demotion hint. The track is demoted from the cache in response to the request for the track comprising a read request, returning the track to the read request, and the track is indicated in the transient cache list.
