Accounts for security scans

Hi, I’m new to Nutanix, coming from the vSphere world.I am working on getting our new Nutanix infrastructure set up to run Qualys scans for security.  I have been looking at the following document:https://portal.nutanix.com/page/documents/kbs/details?targetId=kA07V000000LXYqSAOI am getting stuck at determining which accounts to use to set up authentication, so that Qualys can run its scans on the Hypervisors, CVMs, and Prism Central appliances.  My research shows that adding new accounts via the OS to these components is not supported.  Does that mean that Qualys then has to log in as root, nutanix, and admin respectively, to scan these components?  Or am I looking in the wrong place for the Qualys account to be set up, to scan for vulnerabilities and compliance?  I feel like I'm missing something here.  Thanks!

Cluster: One node fails, Nutanix Data Resilience Status Critical appears

Hello, I understand that if the node fails, the ha function is activated and attempts to recover. If one node fails in a Data Resilience Status Critical state due to a lack of storage space, will the cluster collapse? What happens.

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?
