Abstract
Storage tracks are destaged from the write cache if the host(s) is/are idle and are not destaged from the write cache if one or more of the hosts is/are not idle. The storage tracks are refrained from being destaged from the write cache if the at least one host is not idle. Each rank is monitored for write operations from the at least one host, and a determination is made if the at least one host is idle with respect to each respective rank based on monitoring each rank for write operations from the at least one host such that the at least one host may be determined to be idle with respect to a first rank and not idle with respect to a second rank.
