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.

we are retiring 14 shelves and would like to scrub the disks, before giving them up.
anybody got any pointers ?
(begin rant) on a side note, i think its not fair that netapp does not give a credit when returning disk shelves. (ok rant over)
