Can't install NX G6 AOS 5.10 version?

The NX G6 demo equipment is currently updated with the latest firmware. If you try to install version 5.10 to test the AOS upgrade with the latest version of the foundation, the 4. foundation version will not mount, and the 5. latest foundation version will not configure CVM after rebooting after installation and installation will fail. Is it like this originally?

Can't install the lower version of AOS?

There are still many places where the old version is being used.Even if you try to install it with the previous version (AOS 5.10 or lower version) of the foundation on the G6 device to test the upgrade, it cannot be installed.Is it because all the firmware is up to date? It was the version that was originally installed. AOS 5.10 versions are not installed now?In foundation the log is "Device 2 :The Length of Name is not correct" The phrase continues to print. Please reply from those with experience.

Replacing upcoming EOL hardware process

My 3 node cluster consiting of 1065-G5 nodes is coming EOL this year.  I will be replacing the hardware with a NX-3360N-G8 cluster.  What is the recommended workflow for replacing the hardware?  One thing to note is the current cluster is licensed with Prism Pro and the new one will be licensed with Starter as I’m not using all the features in Prism Pro.Is the replacement as easy as expanding the cluster one node at a time, migrating the workloads and then removing the old cluster?  Will there be any hiccups with difference in licensing?

Running Reapir Host boot disk hung

Using phoenix to reimage a node after a failed satadom, after phoenix is loaded, I uploaded AHV ISO so it can proceed to install AHV/AOS. It turns out I uploaded the  lcm_ahv_el7.nutanix.20201105.2267.tar.gz instead of the AHV-DVD-x86_64-el7.nutanix.20201105.2267.iso. The install is now hung at 75% Node discovery succeeded. I have tried to install the proper iso, but it immediately failed at that same progress. How can I cancel this install so I can try again?​I did find this error in the foundation log. It looks like the error happens if you use the html 5 client to mount the phoenix iso, but I am using the java client.

HA Testing

We have our Nutanix 5 node cluster installed with VMware vSphere 7.0U3. RF=2 so I should be bale to withstand a 1 node failure. I would like to test the HA capability of VMware/Nutanix by taking a node offline abruptly and ensure everything works as expected before placing production workloads on it.I was thinking of placing a test VM on a node and then pulling the power cables and ensuring that VM is powered up on a remaining host.Does anyone have any better or preferred way to test HA?

mutual authentication webhooks

I’m trying to secure webhook communication. I’m using PRISM Element. My callback server uses https and has a web-server certificate installed issued by a local CA. First question is, which CA certificate will PRISM use to validate the callback server certificate? Is it the same CA certificate used for the PRISM web server? Second question, how does the callback server verify that the webhook effectively originated from PRISM? Is this mutual TLS or is there another method? If mutual authentication, what certificate does PRISM use for this?

Cannot put node back to cluster after removal

Hello eveyone,following my last post I eventually got my C node to be alive. (it was not booting nor being visible whatever I tries, always down).I can ping it with both IPv4 and IPv6 addresses, connect to it in SSH, run commands etc.Now my situation is : while I was struggling with my node down, I removed it from the cluster with Prism. I think I could bring it back after… But it does not work.As you can see here, the C node (#3) is now missing :I use the “Expand cluster” tools in Prism Element, I add the node manually, it is detectedI check the mode, validate and it starts to expand.But after a few minutes I get the error :Failure in pre expand-cluster tests. Errors: Failed to get HCI node info using discovery It seems like the cluster refuse to consider the node as “free”, or the node itself refuse to join because it thinks that it is still in the cluster.Thank you very much for any help you could provide
