Abstract
According to one embodiment, a method for accessing host data records stored on a VTS system includes receiving a mount request to access at least one host data record on a VTS system, determining a number of host compressed data records per physical block on a sequential access storage medium, determining a PBID that corresponds to the requested at least one host data record, accessing a physical block on the sequential access storage medium corresponding to the PBID, and outputting the physical block without outputting an entire logical volume that the physical block is stored to. In another embodiment, a VTS system includes random access storage, sequential access storage, support for at least one virtual volume, a storage manager having logic for determining a PBID that corresponds to a SLBID, and logic for performing the above described method. Other methods are also described.
