For easy device identification, you can assign tape aliases to a tape drive or medium changer. Aliases provide a correspondence between the logical names of backup devices and a name permanently assigned to the tape drive or medium changer.
You can view the serial number (SN) information about the tape drives by using the system node hardware tape drive show command and about tape libraries by using the system node hardware tape library show commands.
