How It works

Hi! I've got several questions about the usage of v2 API which I have not been able to solve by myself after looking a little while.on some endpoints, for example, GET /alerts, GET /vms and a few more things are functioning for me as expected, but on other endpoints, such as POST /vms/{uuid}/set_power_state I am receiving the following response:{ "message": "Access is denied", "detailed_message": null, "error_code": { "code": 1100, "help_url": "http://my.nutanix.com" }}any idea what's causing it? I've been searching for detailed information on your error code (such as 1100 listed above) and couldn’t find. Is there any documentation to the error codes that  you can send me a link to?Also, in a few of the API endpoints I couldn’t understand exactly what is the expected query parameter to be sent.2 examples of endpoints I felt I am lacking knowledg

Switch engineer changed vlan (vlan id). Is it possibly auto update in nutanix arp table? if not, what kind of command require to do? 

Network visualization Is one of those underrated but extremely useful features. Network visualization is a consolidated graphical representation of the network formed by the VMs and hosts in a Nutanix cluster and first-hop switches. Nutanix network visualization allows you to group VMs by power state or by parent hosts, group hosts by parent clusters or select a particular node from the cluster. Choose your layout based on the current needs.

Can anyone explain the function of the command “nodetool -h 0 ring” and also the explanation of its output, because I often see nutanix support using this command, i just curious function this command :D

I am trying to execute a remote PS script in a windows server using the playbooks. Have kept the script very simple for now to test the execution, but I get the error “ Failed to execute action with error: Internal Error, Connection reset by remote peer.” every time its executed.Execution Start Time: 01/06/21, 5:21:32 PM Execution End Time: 01/06/21, 5:21:32 PM Result: FAILEDInputUsername: serveradminPath to Script: E:\NutanixPS\Nutanix-CVM-Post-reboot-checks.ps1Password: ********IP Address/Hostname: 10.32.135.100HTTPS: True Has anyone faced a similar issue and what is the fix?

In some cases, you might have to permanently remove a physical node / host from a Nutanix cluster. There are two scenarios in node removal. Permanently Removing an online node Removing an offline / not-responsive node in a 4-node cluster, at least 30% free space must be available to avoid filling any disk beyond 95%. You cannot remove nodes from a 3-node cluster because a minimum of three Zeus nodes are required. Some Points to consider before initiating node removal: Sufficient Disk space available on other nodes in the cluster User Virtual Machine relocation (if required) Any software upgrade should not be running Checklist on verifying cluster health status Data resiliency is “OK” (green) in Prism Ru

What is happening to my 2 node cluster during a failover or an upgrade?What does a recovery process look like after a node failure?If you are wondering the above, we have the answer for you! You can monitor the progress of your 2 node cluster in these situations through Prism Element.To monitor node recovery progress after failover: Registering a witness is highly recommended to help the cluster handle the failover situation automatically and gracefully.  Stand-Alone mode: A failed node would trigg

Prism Central includes machine-learning capabilities that analyze resource usage over time and provide tools to monitor resource consumption, identify abnormal behavior, and guide resource planning. These tools include VM "right sizing" where VMs are analyzed and those that exhibit inefficient profiles are identified. Anomaly detection to record when performance or resource usage is outside an expected range based on learned VM baseline behavior. "Smart" alerts that trigger when specified anomalies are recorded. Reports that summarize cluster efficiency. VM Right Sizing

Nutanix takes a holistic approach to security with a secure platform, extensive automation, and a robust partner ecosystem. The Nutanix security development life cycle (SecDL) integrates security into every step of product development, rather than applying it as an afterthought. The SecDL is a foundational part of product design. The strong pervasive culture and processes built around security harden the Enterprise Cloud Platform and eliminate zero-day vulnerabilities. Efficient one-click operations and self-healing security models easily enable automation to maintain security in an always-on hyperconverged solution.Since traditional manual configuration and checks cannot keep up with the ever-growing list of security requirements, Nutanix conforms to RHEL 7 Security Technical Implementation Guides (STIGs) that use machine-readable code to automate compli

Here I discuss the effects of Enabling or Disabling Deduplication on a container even if the Container has data already written to it. The benefit of Compression and Fingerprinting+Deduplication is to hold more data in the container, by reducing the stored size and avoiding duplicate data, respectively.Nutanix’s intelligent selection of dedupable candidates prevents deduplication being performed where the benefit would be low. Deduplication Best Practices: Enable deduplication

Have you guys been utilizing the Analysis charts feature effectively? It gives you the ability to create charts that can monitor a variety of performance metrics over a week, month, or a custom time range.  Here are a few ideas on how we resolved some issues seen in the field.  Memory Usage (%) - Create a chart to track memory consumption or one or multiple VM’s over a time interval   Hypervisor CPU Usage (%) - Measure the CPU usage of one or more hosts over time and gain a better understanding of resource constraints if any   Storage Controller Latency - This is particularly useful if yo

LCM (Life Cycle Manager) is a tool provided by Nutanix to upgrade firmware and software across a Nutanix environment. Depending upon the type of firmware that needs to be upgraded, a reboot of a node may be required.While reviewing the inventory of software/firmware that needs to be upgraded, you may not know which upgrades require a reboot of a node (or not). This information might be crucial in determining the impact and precautions that need to be taken in planning for the upgrade event (change windows, time allocated, etc.).KB 6107 details which upgrades require a node or CVM reboot and which ones do not.

In many ways, identifying the problem is harder than solving it. At least in IT.In order to better understand the performance of Nodes in a cluster and User VMs, ESXTOP for ESXi hypervisors and TOP for Linux OS based machines provide us an immediate birds eye view of the performance of the host. It is important to understand the output as a tool towards problem-solving. Here I aim to discuss scenarios you might need to isolate and troubleshoot High CPU observed at the Hypervisor or User VMs.ESXTOP : This command when run lists live CPU statistics specific to the Node the

PCI device enumeration is one of a large number of concepts that transitioned from the physical world. Originally, being a bus and a slot number now, of course, is a virtualised concept.When OS boots during the POST process the local devices are enumerated (checked for presence and size). If an expected device is found at the PCI slot that is a failure of the test. In AHV deployments, the Controller VM (CVM) runs as a VM and disks are presented using PCI passthrough. That means that if AHV PCI devices enumeration has changed CVM may not be aware of the fact and attempt to direct I/O to the devices that are no longer accessible via known PCI bus and slot. This can happen after hardware replacement on an AHV host and the CVM will not boot or will boot with only part of the expected devices accessible. 

Anyone have an issue where you are not able to apply labels anymore to VMs after upgrading to 5.18.1.1 AOS and Prism Central pc-2020.9.0.1?  I am unable to apply labels after upgrade.
