Deployment Success

Nutanix provides customer support services in several ways:The Pulse feature sends diagnostic data from customer clusters to Nutanix Support on a regular schedule. This enables Nutanix to deliver proactive, context-aware support to customers, monitor customer clusters and provide assistance when, or even before, a problem occurs. This data collection is anonymized, securely transmitted, has no effect on system performance and only basic system-level data needed to monitor the health and status of the cluster are collected. The Pulse framework also allows Nutanix Support Engineers to remotely collect logs from customer clusters on demand with customer approval but without needing assistance from the customer. This saves time in the data gathering stage of the troubleshooting process. Instead of asking the customer to run commands and send the output, which could go back and forth several times, the Support Engineers can just collect the logs themselves via the connection provided by Pul

Hii am trying to move from Esxi to Esxi but it gave this error Could not connect to ‘IP_Address’. Error : ’Get https://‘IP_Address’/PrismGateway/services/rest/v2.0/cluster/: dial tcp ‘IP_Address’: connect: connection refusedany ideas please

We have below script which is changing VM's project from default to some other project but after we execute invoke-webrequest, we notice that it will change Vm's "spec_version" to different number than it's in out $body variable. That's the reason why invoke-webrequest is given below error. Just before we run invoke-webrequest, we checked that vm's configuration metadata "spec_version" is same than in $body that we are trying invoke. So it seems that invoke-webrequest is somehow first changing the vm's spec_version in vm's configuration data (in our case to 18) and after that trying to invoke spec_version = 16 on top of that. But because the version should be same, it's failing. Same error occured when you are trying the same in REST Explorer - "vms".

Not every environment opts for VMware DRS license. While LCM upgrades rely on resource scheduler it is still possible to achieve success in hypervisor upgrades without DRS feature.Things to consider as part of preparation for the upgrade:Compatibility matrix. Redundancy factor (must be at least RF-2 for a non-disruptive upgrade). Third party applications dependencies. For example, where Zerto Z-VRAs are present, additional tasks may be necessary to avoid disruption to live replication.Refer to vSphere Administration Guide for Acropolis (using vSphere FLEX Client): ESXi Host Upgrade Process  for detailed process guide.

Nutanix Era provides Database as a Service (DBaaS) that simplifies database provisioning and management. Nutanix Era automates and simplifies the operations such as provisioning of databases and copy data management.An administator may wish to decommission Era. Essential workflow would be:Remove all DB’s from Era from Databases page. Remove all Database Servers from Era. Delete all Software Profiles from Era. Wait for all the database and database server removal operations to finish. From Prism, delete the Era VM from the cluster.More detailed instructions are outlined in Era Uninstallation Guide.More about Era can be found in Era User Guide.Coffee reading Tech Note: Nutanix Era Time Machine: Under the Hood.Nutanix University has entire playlist of educational videos on Nutanix Era.

Are the MAC addresses assigned to a VM at creation static - as with other hypervisors the MAC address can be changed at reboot.

If you have a 3 node cluster and your data resiliency is okay, you can handle a failure of 1 node, this is termed as FT-1 (Fault Tolerance), or alternatively RF-2. RF-2 is Redundancy Factor - 2, which states that all data in your NX environment has another copy distributed in your cluster, which makes it possible for the cluster to sustain a single component failure and is the default fault tolerance configuration for your cluster. What if you're handling a larger cluster and your workload is extremely critical? Redundancy factor 3 is a configurable option that allows a Nutanix cluster to withstand the simultaneous failure of two components by saving 2 copies of all your data in two different nodes in your NX environment. The requirements for RF-3 are as follows- Minimum number of Nodes in your environment should be 5 and the storage containers should be RF-3. Want to know more about how RF-3 works? Redundancy Factor 3 So what if you created a storage container with RF-2 and

Prior to AOS version 5.1.2 memory_reserved had not been populated at the time of VM creation. Once the VM was powered on the memory_reserved field was populated and the value remained persistent even when the VM was powered off. The issue was fixed in version 5.1.5 and 5.5 and above. It is important to remember that there is no over-provisioning of memory in AHV. The "total provisioned memory" amounts to all the memory configured on all VMs regardless of power state. The "total reserved memory" is memory configured to all Powered on VMs only.

Hi, We have several Hyper-V servers. We intend to implement Nutanix to replace those Hyper-V servers. We have been given Nutanix Collector win32 v2 to run collecting the information of the Hyper-V servers to estimate what Nutanix to buy. However, I don't know how to run it. Has any one run this before ? Is there any guide document ? Thank you very much for your help.

Once you complete firmware upgrade start prepping for another one. Eternal compatibility matrix checks, arguments with vendors on a version that is supported by both compute and hypervisor, forgetting to include plugins into upgrade and the list just goes on and on. Sounds familiar? There is a way out. Developed as the second generation of one-click upgrade LCM simplifies this problem for Nutanix environments. LCM provides a single process in Prism that identifies and qualifies upgrade paths against tested and validated versions, then uses a nondisruptive one-click process to complete the upgrade. LCM can perform firmware upgrades on the following server platforms: Nutanix NX appliances. Dell XC and XC Core appliances. Lenovo HX and HX Core appliances. When you upgrade firmware, we recommend that you use the latest versions of AOS, Foundation, and LCM. Quick snapshot of LCM workflow: Interested? Start with LCM glossary.

Occasionally you need to temporarily power off your cluster hardware for maintenance, relocation or any other necessary task. To do this you will need to stop your cluster and then start it back after the required task was done. But you will need to perform the following tasks before and after the cluster stop/start commands: 1- Disable any “Protection Domains” in the cluster and make sure there is no ongoing replication occurring. 2- Make sure no “Fail” message appears when performing the ncc health check on the cluster 3- Power off all the Vms running in the cluster 4- Stop “Files” (previously AFS) if you are using it in the cluster 5- Run "cluster stop" command 6- power off all CVM 7- Put all hypervisors in maintenance mode 8- Power off the hardware After the maintenance and powering on the hardware, you will need to undo the above steps. Put nodes out of maintenance mode and make sure all Cvm are powered on, to run the command “cluster start”; you could then go ahead with st

Hello I'm new to Nutanix and setting up a small 3 node cluster with ESXi. Just wanted to know whether there is any automatic migration from Nutanix side in case of resource contention on 1 node. One such example: if there are too many VM hosted on a single node and causing storage contention, is there any option on Nutanix to automatically migrate some VM to other nodes (similar to what VMware DRS does - but this time, for storage) Thanks

I'm curious to find out how folks have been implementing departmental shared folders in nutanix files. We are currently running SMB files from a NetApp filer which has the ability to setup Qtrees/quotas for subfolders of the top level share. Is this possible in nutanix files as I'm not seeing anything in the documentation around it.

Hey all, Does anyone have, by any chance, a disk descriptor file for the new CE image file? I am installing CE as a single node and when performing the upgrade by uploading the binaries it fails constantly. Most likely due to NTP restrictions because my lab admin has NTP blocked on this network. I also don't have access to VMFS on the hosts to make a descriptor file. Hopefully someone out there has one similar to the last version. Thanks

if you are trying to set “Enhanced vMotion capabilities” (EVC) on a running cluster, you may see a pop up Error Window saying: “… Powered-on or suspended Virtual machines on the host may be using cpu feature hidden by that mode” You can create a new cluster in vSphere and set the EVC on it first with no hypervisor, and then move the nodes and Vms from the old cluster to the new cluster. Please follow the link “Unable to Set Enhanced vMotion Capability (EVC) on a Newly-created Cluster” for detailed instructions.

Hello, We are running out of network ports in our datacenter so we thinking of reclaiming the existing Nutanix IPMI network cables and instead use KVM dongles for those. I want to check with everyone here to make sure that there are no functional issues with loosing IPMI connectivity or does Nutanix need IPMI connectivity all the time. Let me know your recommendations.

This is my first script using the Nutanix provided Powershell cmdlets. Everything has been pretty straight forward so far. But i'm having one problem, i think someone will probably know off hand. I'm building a report. In this report it should have next snapshot time for protection domain (Easy enough). But also last snapshot created time (haven't found it yet). Anyone will ing to assist? I'll show the two object types i'm building already in the script. Basically PD's and Cron schedules. code:$pd = Get-NTNXProtectionDomain | where {$_.Active -eq $True}#Showing basically how the loop is setupforeach($p in $pd){$e = (Get-NTNXProtectionDomainCronSchedule -PDName $p.Name).userStartTimeInUsecs#showing how my custom object is built$dpcust = @{ ProtectionDomain = $p.Name VMName = $p.vms.VMName -join "," NextSnapshot = $scheduledtime Usage = $convertUsage Schedule = $p.cronschedules.Type LocalRetention = $p.cronschedules.retentionpolicy.localmaxsnapshots -join ","
