Abstract:
A computer-implemented method, according to one embodiment, includes: receiving an unmap command which corresponds to a first logical extent located in a higher storage tier, unmapping the first logical extent from a first physical storage location in the higher storage tier, marking the first physical storage location as dirty, receiving a map command which corresponds to the first logical extent, determining whether the first physical storage location is still marked as dirty, in response to determining that the first physical storage location is still marked as dirty, determining whether any data included in the first logical extent has been modified since the first logical extent was stored in the higher storage tier, and in response to determining that at least some of the data included in the first logical extent has been modified, using the modified data to update the data stored in the first physical storage location.

Claim (Index 8):
A computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions readable and/or executable by one or more processors to cause the one or more processors to perform a method comprising:\n receiving, by the one or more processors, an unmap command which corresponds to a first logical extent located in a higher storage tier of a multi-tiered data storage system having the higher storage tier and a lower storage tier, each storage tier comprising a plurality of hardware-based data storage devices; unmapping, by the one or more processors, the first logical extent from a first physical storage location in the higher storage tier; marking, by the one or more processors, the first physical storage location as dirty; storing, by the one or more processors, information which links the first logical extent to the first physical storage location; receiving, by the one or more processors, a map command which corresponds to the first logical extent; determining, by the one or more processors, whether the first physical storage location is still marked as dirty; in response to determining that the first physical storage location is still marked as dirty, determining, by the one or more processors, whether any data included in the first logical extent has been modified since the first logical extent was stored in the higher storage tier; and in response to determining that at least some of the data included in the first logical extent has been modified, using, by the one or more processors, the modified data to update corresponding portions of the data stored in the first physical storage location.
