Not sure if this is an option for you but if the VTL encrypted the data on disk, securely wiping the encryption keys would render all data wiped.

For example, if the disks are SATA, you could put them on a PC running Linux and simpy do the command: "dd if=/dev/random of=/dev/sd?" where "sd?" is the Linux address of the attached disk. This would overwrite the entire disk with random bits. If you are really paranoid: for i in 1 2 3; do dd if=/dev/random of=/dev/sd?;done To do the overwrite 3 times. If the attachment is SCSI, there are SCSI HBAs for PC. Example: https://smile.amazon.com/Dell-Non-RAID-Serial-Attached-External/dp/B0153IR6QY/ . That is a example, not a recommendation. Also, if SAS, https://smile.amazon.com/SAS9211-8I-8PORT-Int-Sata-Pcie/dp/B002RL8I7M/ But erasing the entire drive is likely to make it unusable in the VTL. Have you asked the vendor if the software driving the VTL has a mass erase function? I know that the old IBM Shark had that. > > *George Rodriguez* > > *Specialist II - IT Security* > *PX - 47652* > *(561) 357-7652 (office)* > *(954) 415-7586 (mobile)* > *School District of Palm Beach County* > *3348 Forest Hill Blvd.* > *Room B-332* > *West Palm Beach, FL. 33406-5869* > *Florida's Only A-Rated Urban District* > > > On Thu, Sep 13, 2018 at 2:29 PM Mike Schwab <mike.a.sch...@gmail.com> > wrote: > > > Overwrite each tape with a one track dataset of low values. > > Then overwrite tapes with a very large dataset of low values until VTS is > > full. > > Repeat one track / large datasets with high values and b'01010101'. > > > > Repeat the 3 cycles until desired number of overwrites are accomplished. > > > > On Thu, Sep 13, 2018 at 10:16 AM George Rodriguez > > <0000016eebd7289b-dmarc-requ...@listserv.ua.edu> wrote: > > > > > > The School District of Palm Beach County is finally shutting down the > IBM > > > z10 and all its components. > > > > > > I was wondering if any member the listserve can help me with "wiping > out" > > > out VTL.
