Hi Team,
I executed the NCC health checks run_all on two clusters and got the following message (at the end of the run_all script):

The cluster is running smoothly and no errors are shown up, but I would like to know what kind of issue are the provoking these messages.
Thank you!

Hey - Thanks for reaching out.
First, I'd recommend opening a support ticket, so at worst, they could track this as a bug.
That said,
What version of NOS is this cluster running?
If it's above 4.1.3, you can upgrade NCC to a later release, without upgrading NOS.
You should be able to do that from 1click upgrade software if you have internet access from the cluster.
NCC 2.2 recently came out with the release of NOS 4.6, but again, you can install this back on 4.1.3 and above clusters.
I'm guessing this is just a silly bug, but if its still happening on a newer version of NCC, definitely open a support ticket if you haven't already.

Hi Jon,
The cluster is currently running NOS 4.1.5 and NCC 2.0.2.
So I assume it might be a bug in a previous version of NCC / Nutanix. I will pay attention if we run into the same issue during the next nutanix installation.
Thank you,
Andreas

You can upgrade NCC to the latest version (2.2) non-disruptively, right from the GUI.
If you do that, and are still having problems, please open a support ticket so we can track

Better later then never..
I was a bug as confirmed from Nutanix side and has been fixed with version 2.2 / 2.5 already
