Installing new 8.1.2 C-mode image

OPHELIA_GENTRY — Thu, 05 Jun 2025 06:09:56 GMT

Hello,

I have an FAS2040 running DOT 8.1 7-mode. I'm going to wipe it out completely (data migration is not important for my project) and install 8.1 C-mode on it.

I've downloaded 812P1_e_image.tgz and have run "software update" and it appeared to simply install DOT 8.1.2 7-mode on the controller. I rebooted, and entered the Boot Menu, and reinitialized the disks (option 4), but once again, it came back up on 7-mode by default. I was expecting to be prompted for 7-mode or C-mode during the setup, but this did not happen.

What am I missing here? I have not been able to locate any documents or forum threads on how to install the C-mode software image. All comments, tips and insight on the process are very welcome here. Thanks!

Are you going to be using the 2040 for test purposes?

You can convert an existing 7-mode system to c-mode by following the steps in this KB article: https://kb.netapp.com/support/index?page=content&id=1013517&cat=DATA_ONTAP_8_CLUSTER_MODE&actp=LIST

You will also need to keep licensing in mind.

Yes, our old FAS2040 is only for testing - hence our best candidate to try out C-mode.

Thanks a bunch for the link to the KB. I missed it while reading through the KB listings under C-mode. I'm going through it now... will know in a few hours once all the zeroing is done!

Not a problem, reply back when you are done with the conversion. I also have a 2040 I use for testing that I was thinking of converting to C-Mode.

C-mode successfully installed on the FAS2040. Moving on to configuration. Dan - let me know if you want details, I have captured most of my installation steps.
