Cluster name must be in FQDN format | Nutanix Community
Skip to main content
While attempting to upgrade from v4.7.1 to v5.x.x, the pre-upgrade fails with the following error: "Cluster name must be in FQDN format."



Is there a way to upgrade the name from "CLUSTER" to "CLUSTER.domain.com" without downtime?

Or, alternatively, is there a way to perform the upgrade without making this change/ingoring this message?



Thanks all!
Interesting question Coleman - let me see if I can find out.

Hi Coleman -- What is the hypervisor? It sounds like you have Hyper-v.
Hyper-V - Correct
It sounds like the cluster is not joined to the domain. I am just boarding a plane as I type. If no one else has answered I will send you a couple troubleshooting steps.
OK first.



Under the gear icon, can you select Join Cluster and Hosts to the Domain? If so, please follow the dialogs to join it to a domain.



If not here is the Nutanix portal URL on how to update the cluster name.

Please provide feedback to James question if the clsuter is joined to a domain or not.



thanks

Thanks for the feedback.



My clusters are domain joined and I don't have the option to "Join Cluster and Hosts...".
