in the background (some status
messages have been removed to save space) and one in the foreground. 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.

6.4.2 Tape volumes
Tape volumes require a different procedure to make them ready for use. 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
