When I use the license, I remove all essential disks (i.e. keep the ones I want to sanitize in the system)
I then boot to main menu, choose #4 to zero and install.
After it is done, I install the OS as normal and then add the DISK_SANITIZE license.
I then sanitize all the disks that are left. I am still left with two right.

I create a new root volume on two of the sanitized disks and then delete the old root volume
and sanitize those disks.

fyi -- the disk sanitization license is not removable so be careful
if you want to use it.  It was aimed at gov/military sanitization
requirements so you can't remove it mid stream and then look at the data
thats left.

Re-initializing the system will only write zeroes to all disk then
create a new root volume.

Disk Sanitizer (free license available from your NetApp rep) is
configurable as to how many passes and patterns you use on the list of
disks you provide to it.  Expect this option to be very lengthy, but
much more thorough than simply re-inializing the entire system or
zero-ing your spares.
