Once all six are created, use query volume to display them. Notice that the storage pool statistics show an estimated capacity of 12 GB. You can also view the files at an operating system level, as shown in Example 6-17.

Firstly, a tape volume has to be prepared. Most modern tape libraries rely on a barcode label on the side of the tape cartridge to provide the robot with information about the cartridge. Most DLT and LTO media come without labels, but typically cannot be used (in a library) without them. You should order labels when you order your tape supples. Labels can be made to your specifications. A label normally has three letters (that you can choose to be meaningful if you like), and three numbers that typically run in sequence for each label (for example, IBM000, Chapter 6.
