tape cartridge cannot be overwritten or erased.
The displayed data can be sorted by any field by

RAID group procedures
You may change the RAID groups underlying
your VTLs using the ExpressNAV interface.
Increase the size of a VTL
If you have unallocated drives, you can increase
the number of drives used by an existing VTL by
adding an unallocated drive to the VTL RAID
group. The increased capacity of the RAID group
becomes additional Virtual Tape cartridges in the
library. You may have to add more than one drive.
