Why we need a CTO Image?
If a CTO node was smartfailed, it was removed from the cluster.
- Why we need this special CTO image to re-image the node?
- Why we can not use the standard image or better, what if the problem if we use the standard image and join the node to the cluster?
If we receive a new node from the factory, it has the standard image on it. What is the difference here?

Hi JoZi,
The CTO image refers to the hardware information on the node rather than the OneFS version. CTO stands for Configure To Order, so there is no standard image on a CTO node. I believe you are thinking of the OneFS version, not the CTO information. A node should come from the factory with the correct CTO image on it. You should also be able to reimage (OneFS) the node without the CTO image. You would need the CTO image in the rare case the node loses its CTO image information or in the case of upgrades.
I believe you should have access to this document. Check out CTO Basics here: https://support.emc.com/docu54707
