Local Key Manager (LKM) for DaRE

Greetings, Does the Nutanix Local Key Manager (LKM) satisfy the recommendations/requirements to safely implement the Data at Rest Encryption?The documentation at: https://portal.nutanix.com/page/documents/details?targetId=Nutanix-Security-Guide-v6_5:wc-security-data-encryption-aos-wc-c.html has the warning: "Caution: DO NOT HOST A KEY MANAGEMENT SERVER VM ON THE ENCRYPTED CLUSTER THAT IS USING IT!! Doing so could result in complete data loss if there is a problem with the VM while it is hosted in that cluster." I too share this concern, which led me to investigate External Key Managers, but I am wondering how does using the LKM alleviate this risk? Also, as stated in the Nutanix Bible as well as here: https://portal.nutanix.com/page/documents/solutions/details?targetId=TN-2026-Information-Security:TN-2026-Information-Security "Now that Nutanix supports its own native LKM, Nutanix also takes the KEK and wraps it with a 256-bit encryption key called the machine encryption key (MEK).

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.

How to provide guest credentials when creating Move plan through API

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

Moving VMs from one AHV Cluster to another AHV cluster

I was intially told I could use Move to take VMs from old Cluster to New Cluster but alas Move does not move from AHV to AHV, this I find very bizarre as that should be more simple than moving esxi to ahv!So, I have been told to use Data Protection failover - this seems complicated and needs VMs to be stopped and restarted - I came across Live Migration using Leap - ah ha that looks like a good option but still apears complex. Do I really need 2 Prism Central instances? Could I add the second cluster to my exisiting Prism Central then use the Migrate function to move some VMs or is the limitation of different harware still the gotcha?Does anyone have any ideas how I can do this “easily” and “quickly” my boss ain’t a happy man as information from Nutanix has been misleading or downright incorrect.Any help appreciated.

Splunk Workload Ingest per Indexer

I am curious why when sizing a Splunk workload and increasing the performance profile for the indexers it doesn’t increase the ingest rate per indexer rather than keeping it at 100 GB. By not doing this, it keeps the same number of indexers Nutanix thinks it needs even though each indexer has more CPU/RAM. I could be missing something simple here, but I would like to hear other thoughts.Capacity Planning Manual: Summary of performance recommendations
