DMS volume types

During file processing, DMS requests the required volumes using the VSN and device type in device management. Strictly speaking, the device type which is used in DMS specifies the volume type.

For a requested volume type the device management provides a device of the appropriate device type. In the case of tapes/MTCs, the volume is mounted on the device provided. In the case of disks, the volume is already “mounted” on the device (here the volume and device type are identical).
