acquire the /*free*/ disk_sanitization code.
WARNING: once enable, you cannot remove...short of zeroing your system
If you install this code, you can run:
disk sanitization start -d d<disk_list>
and it will write these bit patterns in this order to disk:
01010101 (0x55)
10101010 (0xaa)
11000011 (0x3c)
Once the disks are done, they are no longer in the spare pool but can be re-added easily.
Search NOW for more info.

Acknowledged. I think they changed the limit from 10TB to 16TB with
Ontap7, correct? Disc sizes are growing and growing - unless NetApp
changes to solid state disks (flash), a higher limit would be nice to
have.
BTW, I'm searching for a way to securely wipe out all data at our R200
disks. (ATA, 154x274gig) I wanted to build a big volume, but the 16TB
hit me too. Has anyone ever played with 'dd' at Ontap side? Is there a
hidden random device (/dev/random) I can use to create random data? Any
hints? :)
