The virtual tape server (VTS) system provides the ability to physically import (enter) and export (remove) logical volumes within the VTS. This support includes managing the physical removal of the native cartridges containing stacked logical volumes from a VTS and the corresponding function for entering these cartridges into a VTS. These functions require interaction with the host and the tape management system software. See Exporting logical volumes from a 3494 VTS system and Importing logical volumes into a 3494 VTS system for more information.
