Abstract
Storage tracks from at least one host are destaged from the write cache rank when it is determined that the at least one host is idle with respect to a first set of ranks, and storage tracks are refrained from being destaged from each rank when it is determined that the at least one host is not idle with respect to a second set of ranks such that storage tracks in the first set of ranks may be destaged while storage tracks in the second set of ranks are not being destaged.
