convert to 7mode from CDOT shipped systems with 8.3RC2

milan_nemcik — Thu, 05 Jun 2025 04:50:12 GMT

I'm trying to convert brand new system shipped with cDOT 8.3RC2 into 7mode.

Perform the following steps to convert from Data ONTAP Cluster-Mode to Data ONTAP 7-Mode

Disable ‘Storage Failover’ and reboot the node to the LOADER prompt. Do not perform a takeover.
At the LOADER prompt, run the following commands:

To convert from Cluster-Mode to 7-Mode:
LOADER> set-defaults
LOADER> boot_ontap

Stop the boot process at the special Boot menu and select option 4.
The node automatically performs a wipeconfig, zeroes the disks and creates a 3-disk root aggregate with a FlexVol root volume.
Perform the node setup

This action plan worked well with 8.2.x systems but somehow I can't have it done with 8.3.RC2. Even after 2 tries I still ended up with cDOT.

Did something change starting with this version? If the 7mode is not preloaded on CF card, what are my options?

Hi Milan_nemcik,

Please see the 8.3RC2 download page

The download page mentions the below note:

>> Note: There is no Data ONTAP operating in 7-Mode version of this release.

you cannot covert C-mode to 7 mode because of above in 8.3RC2

Hi Srinivas,

that I was afraid of that it applies also to the CF card images. But I still should be able to make a new instalation of 7mode 8.2x, is that correct?

which platform is this ? FAS XXXX ?

and i would recommend you to create a support case before doing this.

FAS2552, we already do have couple of them so they do support 7mode, just to find our with NetApp support how to install it

FAS2552 , 8.2.3 7mode is possible.

Documentation:

please raise a support case, they would be able to guide you to switch the preinstalled c-mode to 8.2.3 7 mode.
