Deployment Success

I am facing an issue with the sizer while generating a budgetary quote.  Help please! 

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.

Hi I deploy a 3 nodes cluster with ESXi 7.0 as the hypervisor successfully on AOS 5.15.3.But when I run the diagnostic.py to check the  cluster performance. It always failed to boot the diagnostic VM. I tried 3 times and all is same. from the log, seems the CVM cannot reache the diagnostic VM when check the boot status.I login to vCenter and check that there is no IP address for this VM in the summary page. And I can login the diagnostic VM from the VM console, I can check the ip address which is 192.168.5.253, but I cannot ping 192.168.5.254 and 192.168.5.1. also cannot ping 192.168.5.253 from CVM.From this information, I think the CVM cannot reache the diagnostic VM and timeout, so the diagnostic.py will fail after timeout. Is there any idear for this test? I can run thie script successfully in ESXi 6.7.

I have 20 clusters under management of our Prism Central and would like to know the versions of NCC installed in each. Is there a way to singularly collect this info across all PE clusters? Perhaps in nCLI even?

So guys I’ve got a flexlm license server running Windows Server 2019 that I am trying to use Move to migrate into my AHV cluster.  I tried migrating it once and it blew up the license server since I guess it builds a unique machine ID using a disk and perhaps CPU ID. Any idea on how to clone this in Move so when it comes across FlexLM and other license daemons are none the wiser?

This article contains IPMI commands for checking and setting interfaces to dedicated or shared mode. For example, after a BMC upgrade, the IPMI might not be accessible. So, you need to verify and change the interfaces to dedicated or shared mode. Note: To run ipmitool commands on an ESXI host, prefix all commands with a forward slash (/). Note: To run ipmitool commands from a remote system such as the CVM (Controller VM), add the "-I lanplus", "-H <IPMI IP>", "-U <username>" and "-P <password>" parameters to the ipmitool command. For example: nutanix@cvm$ ipmitool -I lanplus –H x.x.x.x –U ADMIN –P <password> <command>     Quanta Platform Use these commands for an NX-3400 (Quanta) platform. All commands are executed dynamically and a restart is not required. Check the status. [root@host]# ipmitool raw 0x0c 0x02 0x01 0xff 0 0 An output similar to the following is displayed.1100           :00 - Shared port 1101           :01 - D

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 Run a complete “ncc report” either from prism or CVM cli:                                 ncc health_checks run_all Depending on the size of data, node removal can be lengthy process, which involves relocating data from the node to other healthy nodes in the cluster. Node removal also remo

Hi,I am implementing a Nutanix Cluster with Lenovo HX5520, when I register the Prism in vCenter the process appears as completed but I cannot create virtual machines by Prism Element and when running the NCC I return communication errors with the vCenter is not stabilized. I did the communication test of the CVMs with the vCenter on ports 80 and 443 and the connection worked successfully.  when checking by cli I see that the connection is ok, but it does not provide me with the settings of vcenter follows the difference from another implementation any idea what it might be?

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 trigger cluster to transition into stand-alone mode during which the following occurs: Failed node is detached from metadata ring. Auto rebuild is in progress. Surviving node continues to serve the data. Heartbeat: Surviving node continuously pings its peer. As soon as it gets a successful reply from its peer, clock starts to ensure that the pings are continuous for the next 15 minutes. If a ping fails after a successful ping, the timer will be reset.  Prism Element Home page shows Critical

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 SizingIt is useful to look at the profile of your VMs when analyzing problems in a cluster or assessing future resource needs. This can help you identify VMs that are not optimally configured such as ones that consume too many resources, are constrained, are over provisioned, or are inactive.Anomaly Detection:The right sizing feature identifies inefficient VMs that fit one of the profiles described as below: Bully VM : A

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.

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 Do not enable deduplication Full clones Physical-to-virtual (P2V) migration Persistent desktops Linked clones or Nutanix VAAI clones: Duplicate data is managed efficiently by DSF so deduplication has no additional benefit Server workloads: Redundant data is minimal so may not see significant benefit from deduplication  Enabling Dedupe:Fingerprinting is method of creating signatures of the data in Metadata.

I am moving virtual machines with Move 3.6.2 from Hyper-V to an AHV CE cluster. Everything goes well, but after the cutover the AHV VM is stuck at the ‘Press F2 for EFI boot manager’ screen and cpu usage around 52%. Pressing FN+F2, F2, CTRL+F2, ALT+F2 or other combinations have no effect. Please advise. Hyper-V host is Win2019, VM is 2019 with boot from bootmgfw.efi and secure boot disabled. Also tried with Edge, Chrome and IE, same result, stuck at ‘Press F2 for EFI boot manager’ screen.

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 you suspect performance issues. Creating charts ranging to a few weeks back gives you a comparative analysis and a benchmark for the current latency observed   Storage Container Usage - A classic use case for this is when multiple VM’s have been migrated out of the cluster over many days but you suspect the storage space has not been reclaimed   Replication Bandwidth - Transmitted - If there are

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.

Many users are unaware that there are additional (beyond what is presented via the Prism user-interface) security parameters that can be employed on AHV hosts to increase the overall security of them. These security parameters are configured via Nutanix Command-Line Interface (NCLI) and include the following: Advanced Intrusion Detection Environment (AIDE) - a file and directory integrity checker High Strength Password Enforcement - configure the maximum and minimum number of characters the password must contain along with number of passwords retained in history to prevent repeated use Core Dumps - the recorded state of the working memory for a process is dumped to a file if the process ever crashes Login Banner - display a customized messages when user login to a node More information regarding these parameters, including the procedures to enable/disable them, can be found within the Hardening AHV section of the Nutanix Security Guide. Also to note, there are similar parameters

SAP helps customers migrate from traditional relational databases to their in-memory SAP HANA database to gain more agility in their business processes. Many SAP customers are searching for ways to deploy SAP HANA in an efficient, simple way that minimizes risk while preserving the benefits of an agile platform. Nutanix provides such an option. The native Nutanix hypervisor, AHV, and Nutanix enterprise cloud OS software are certified for production SAP HANA deployments. HCI for SAP HANA CertificationThe certification has two primary segments. 1. As the first step, a platform vendor (Nutanix, in this case) must validate their platform, which consists of a hypervisor and an HCI component.2. In a second step, the hardware OEM must certify a suggested configuration through some additional HCI-related tests. When both parts of the validation are complete, the solution is certified and listed in the HCI for SAP HANA category on the SAP website. The hardware OEM is then responsible for selli
