Doran -
You're very welcome.
I understand title mix up.
Tried to answer to your first post.
Yes, disk sanitize would require a license.
If you're no longer under support, you may still be able to get out of it.
There's two options:
Convince the local NetApp sales rep you'll buy some new NetApp. They could get you a temp license key.
You'd need to also convince your security guys that you're buying the support and license keys for the future.
Option two is to go out and buy a disk shredder. Shredded disks tell no stories.
These are real cool devices. They're like paper shredders, but they chop up disk drives.
I hope this response has been helpful to you.
