Abstract
A computer-implemented method, according to one embodiment, includes: maintaining a heat map monitoring table on a per volume basis for a plurality of volumes in a multi-tier data storage architecture, where the heat map monitoring table includes a heat count for each data block in the respective volume. The computer-implemented method further includes: receiving a request to delete a first volume of the plurality of volumes, identifying which data blocks in the first volume are depended on by one or more other volumes of the plurality of volumes, copying the identified data blocks and the corresponding heat counts to the respective one or more other volumes, and sending a list which includes the identified data blocks and the corresponding heat counts to a controller. Other systems, methods, and computer program products are described in additional embodiments.
