Data ONTAP Discussions

Disk Sanitization



So I was following a few links to sanitize and wipe my old NetApp, it seems as ususal, there are always items missing the NetApp KB's.

The disk unpartition command doesn't work. Neither does the system node run. I was able to get the process started (I think) but then the system, crashed and I"m stuck in this "takeover" boot loop and nothing seems to work now.


Can I not just reboot the node, CTRL+C, option 4 to initialize, zero out all disks, then perform the sanitization after?







Re: Disk Sanitization

What version of ONTAP are you using, or is this 7-mode? What is the platform? Are you actually using partitioned drvies/SSDs?


The process is a little different on ONTAP vs 7-mode, and I think even the earlier versions of ONTAP are different from today


Bottom line, this is something where the sanitization needs to be enabled. Then the disks can be sanitized. Give some info and I will if I can help with the correct commands.


If you can get into maintenance mode (either ontap or 7-mode) the output of "disk show -a" might be useful!

Re: Disk Sanitization

This is 7-mode, verion 8.2. This is a FAS3240.


They were partitioned but I belived in a clunky way I removed that by destroying volumes, RG's etc...They were just spinning disk, no SSD.


I had already enabled sanitization and I belive I got it to run but then at one point the nodes crashed and rebooted.  Then I got stuck in this "takeover" situation wedre the commands to correct that don't sdeem to be working. THat's why I"m leaning towards just zeroing out all disk. Then I know they willl be spares and then run a sanitize.


I will get the output in a minute here for you, if I can get a login prompt.

7-Mode never supported partitioned disks. It sounds like you tried to sanitize root aggregate which you cannot do for obvious reasons. Now you are left without root volume/aggregate. If this is HA pair and partner still works you may try to complete sanitize from partner. If this is standalone controller, it may be possible to do it from network boot, but I am not sure if it will work.


Or you may try to initialize disks and install Data ONTAP again and follow

Here is the disk show -a

Re: Disk Sanitization

I still have my root aggregate, that I didn't delete. But the steps you provided me sound nice.

Re: Disk Sanitization

Now when I boot and press CTRL-C I get a prompt that says "loader A" and that's it.  No menu on either node.

Re: Disk Sanitization

Actually, I got the boot menu to come up and I'm going to try the procedure given.

Re: Disk Sanitization

Re: Disk Sanitization

Not sure is this is working or not. The system is booted I believe but all I'm getting on console is a series of '"....................."


Line after line, after line of dots, so I'm not sure if it's doing something or not.
