Zusammenfassung:Provided are a method, system, and computer program product in which a computational device stores a data structure that includes identifications of a plurality of volumes and identifications of one or more time locks associated with each of the plurality of volumes. The data structure is indexed into, to determine whether an input/output (I/O) operation from a host with respect to a volume is to be permitted.
