How to destroy my Netapp


Goodmorning all,

My FAS3220 is EOL and will be scrapped, what is the easiest way to delete all the data in a way that it cannot be recovered ?

Hope to hear from you.





You can make use of Disk sanitization feature: [It's free]
Disk sanitization enables you to remove data from a disk or set of disks so that the data can never be recovered.

Useful links: [Covers both 7-mode and cDOT/ONTAP]
How to perform Disk Erasure, Disk Clearing and Disk Sanitization



Thank you for your info !

Before santitizing the disks they must be marked as spare disks, can't find the command to make them spare.

any help is appriciated






Are the disks that you intend to convert to 'spare' part of an aggregate ? If yes - You must destroy the aggregate, all the disks will be converted to 'spare'. Before that : Make sure the aggregate does not contain volumes (data) that are or will be neded in future. If so, then first move those volumes to another aggregate.


Is that your query ?


My problem is that if I try to put the aggragate offline it comes with :


dtgfiler1> aggr offline aggr0
aggr offline: Cannot offline aggregate 'aggr0' because it contains one or more flexible volumes.












Are the volumes in the aggregate :  still there ?  You must offline and destroy the volumes before you could destroy the aggregtes, this is to ensure that you do not want to keep anything.



All volumes are deleted except vol0, this volume is still online and cannot set offline...




Use the force command. Is it cdot ?


Plz take a look at the kb. Let me know if you can access it.


Fas3220 is running Ontap 7, the commands in the KB don't wordk


My last reponse was from my phone, so didn't really read what your version was.


It's 7-mode I can see that, that article will not apply.


I saw that it's an root aggregte : aggr0,  therefore, root_vol cannot be taken-offline. Therefore, plan will be :


1) Boot up, erase all the disks.

2) Create Raid-4 (2 disk) or Raid-DP (3 disk) root vol

3) When system boots , all the rest of the disks will be spare.

4) Do the saniatizaiton job.



I will send you the steps, shortly.


Steps to convert disks as 'spares' for sanitization purpose: [Objective : To erase all data & destory filer]

1) Reboot the filer and press ctl+c (holding control key and C key together) early in the boot process where it says (in effect) type ^C to get the boot options menu.

2) From the menu select item 4) Initialize

3) After you have selected option 4, you should be prompted by

Zero disks and install a new filesystem? Answer "y"
This will erase all the data on the disks, are you sure? Answer "y"

4) Once the disks are erased, filer will begin to boot again, when prompted, enter Ctrl + C for the special boot menu.
Set up the root volume aggregate.

4a) choose Option 4a from the special boot menu. Option 4a is only available if running Data ONTAP 7G or later.

5) Once filer boots up (set it up with minimum config) and have you gained access to console (filer>), you can then begin the 'sanitizaiton process' on the spare-disks as per the kb article shared earlier.

Dear all,

With help of an ex Netap engineer I managed to destroy the data on the FAS3220. Actions were as mentioned above ...

Thank you for your help.




Good to hear that.  Thanks for the update. Good luck!
