If the adhesive label on the volume is missing or illegible, you can determine the volume's name from the Backup administration program or the command line, complete one of the two actions:
In the Backup administration program, either
Mount the volume and view the volume name in the Devices display, or
Start a labeling operation and view the Volume Name field in the Label resource, then cancel the operation.
At the shell prompt, enter the nsrmm command with the -p option to show the label of the volume loaded in a device.
