Abstract
A computer-implemented method for accessing data stored in a virtual tape storage (VTS) system, according to one embodiment, include receiving a mount request to access at least one host data record in a VTS system, issuing a locate command to position the sequential access storage medium having the logical volume stored therein to about a position where the physical block having at least a portion of the requested at least one host data record therein is located; creating a partial virtual volume in a tape volume cache; and copying the physical block having the at least a portion of the requested at least one host data record therein from the sequential access storage medium to the partial virtual volume in the tape volume cache. An amount of data copied from the logical volume to the partial virtual volume is less than the amount of data in the logical volume.
