Deployment Success

After updating era on my dev system from 1.1 to 1.1.1.1 it is continually creating systems task for era_auto_snapshot  which are all stuck in waiting. I now have over 2000 tasks since the update 10 minutes ago

Have multiple Windows VMs running in your environment and want to install Nutanix Guest Tools silently in the Windows VM?You can absolutely do it with a little help from Nutanix and the power of automation scriptsSo how can you achieve this?There are two methods If you are a nerd techy, you can write a custom script using silent installer package.  If writing scripts giving you chills, we still have a procedure to install NGT silently with reduced clicks.Procedure Go to command prompt and browse to the drive where NGT is mounted Execute the following command  drive:\> setup.exe /quiet ACCEPTEULA=yes /norestart Use this command to ensure that VMs are not restarted after installing NGT. Note that if you use this command driver will not be updated. You need to manually restart the VMs to update the drivers.  drive:\> setup.exe /quiet ACCEPTEULA=yes If you use this command, VMs are restarted and drivers are automatically updated.Want to see the logs?In Event Viewer and in the %TEMP% 

Hello, I'm ssh'd into our CVMs and trying to change the default "nutanix" password using the passwd command. I'm getting the following error: passwd: Authentication token manipulation error Am I doing this incorrectly? Any suggestions? Thank you

Hi We currently use Files and I have created an SMB share. The share is setup to store disaster recovery information in the event a production failure. We use Data protection to replicate the share to another Nutanix cluster at another site.We want the ability to access this share in the event that our Active Directory isn’t available. I was looking for a location either in PE or PC where I could create local accounts and assign them as a user to this share but have been unable to find.Is this possible to do? Thanks 

Nutanix Move Can't migrate vm (SQL) in vmware it show  PCIE pass-through not support only 1 Server. Thank you for answer. 

Should you need to access container’s content directly, upload files to or download files from a container on AHV there is a simple guide with few things to remember: Do not delete any data from the container via WinSCP or any similar tool. Appropriate Prism or CVM command line workflows should be leveraged for doing the cleanup if needed. Deleting VM disk files directly from Nutanix container may affect Acropolis service, which can result in inability to manage user VMs.How to upload VM disk files from your workstation to Nutanix containerUsing WinSCP, connect to a CVM using SFTP protocol and port 2222 using Prism element credentials. Enable the option to show hidden files by going to Options > Preferences > Panels and then selecting the “Show hidden files”  option under the common settings. Select desired Nutanix container and upload file. How to download VM disk files from Nutanix container to your workstationPower off user VM, which disks will be exported, to avoid data corru

Let’s say you’re running a Nutanix cluster with ESXi as a hypervisor and noticing a lot of files in your datastore and different service crashing.You’re running a VDI workload and number of files in the datastore is exceeding 30,000 and the vpxa service is crashing. This can be critical for your infrastructure as vpxa is responsible for communication between the ESXi host and the VirtualCenter Server. Does Nutanix give you a warning before the file limit is reached?Absolutely yes!The NCC health check nfs_file_count_check verifies if an NFS datastore has more than 20,000 files.Want to run the check individually?  Login from any CVM and try running the following command: nutanix@cvm$ ncc health_checks hypervisor_checks nfs_file_count_check Nutanix recommends that the number of files in any datastore should be less than 20,000 if vpxa instability issues occur.Want to manually check the number of files in any datastore?Try running the following command from an ESXi host shellfind /vmfs/vol

The Simple Network Management Protocol (SNMP) enables administrators to monitor network-attached devices for conditions that warrant administrative attention. In the Nutanix SNMP implementation, information about entities in the cluster is collected and made available through the Nutanix MIB (NUTANIX-MIB.txt). The Nutanix enterprise tree is located at 1.3.6.1.4.1.41263.The Nutanix MIB is divided into the following sections:Cluster information. Status information about the cluster as a whole. Software version information. Version information about the software packages that comprise the Controller VM. Service status information. Information about the status of essential services on each Controller VM. Hypervisor information. Information about each hypervisor instance. Virtual machine information. Information about hosted virtual machines. Disk information. Status information about the disks in the cluster. Controller VM resource information. Indicate how much CPU and memory capacity is

If you are running AOS 5.10 or later, you may notice some user VM in Prism show two IP addresses. This could happen if the VM releases its older IP address and acquire a new one. You will see both old and new IP addresses in Prism for this VM, even if VM uses a temporary IP address like APIPA addresses (APIPA addresses fall into 169.254.1.0 - 169.254.254.255 range and use 255.255.0.0 netmask)This is by design and should nto last more than 10 minutes as we scan the arp cache every 10 minutes as we scan the ARP cache every 10 minutes to detect duplicate entries, and remove all entries corresponding to an IP address except for the most recent one. Tis has been explained in your nutanix portal kb 7652.

While migrating nutanix VM to AWS it is giving me error while launching it which is Could not find /.nutanix_active_svm_partition Aside to this while converting into the AWS image it is giving me this error : "ClientError: Multiple different grub/menu.lst files found Can you help is sorting this out? how it support to be deployed on AWS.

In modern IT Infrastructure, data is critical and having a copy of your data from where you can recover from has become an important pre-requisite for system design. To achieve this we use a technology known as Snapshot.So is it possible to even save your system running state while taking a snapshot in Nutanix environment?Absolutely YesIn Nutanix, we provide a technology known as application-consistent snapshot which can be selected when configuring Data Protection Domain.Want to know more about Data Protection with Prism elementGive the following article a readData Protection Guide So Nutanix have some guidelines with regards to Application consistent Snapshot?Absolutely yesNutanix recommends installing NGT on the VMs. Microsoft VSS service should be enabled. The workload running must be able to support to quiesce I/O operations. You must configure one consistency group for each VM. For the protection of VAAI clones with application consistency, each VAAI clone should be in its own pr

Hi,Is it possible to install X-Ray machine in a host outside of Nutanix Cluster nodes?

Reliable and Accurate Time Sync is mandatory for distributed services to work in a reliable / efficient manner.Network Time Protocol (NTP) is used across different devices and services on a network to maintain reliability and integrity of services, data and other critical functions.Nutanix - AOS, built on web-scale engineering principles, distributes roles and responsibilities to all nodes within the system to form a large cluster of services working together. Accurate time sync becomes a vital requirement for all the different components to work reliably and help keep up system integrity.Accurate time sync, not just offers integrity and smooth operations but offers a lot of value even when things don’t work as they should. During troubleshooting of any service, timestamps are used to understand and co-relate root-cause, impact of the problem.In order for a distributed system such as Nutanix AOS to work smoothly - NTP is of critical importance. CVMs (Controller Virtual Machine) that co

Just curious if there is going to be an update to the Move API documentation to explain how we can create a migration plan from ESX to AHV. Currently the only example shown is for AWS to AHV and when we try to substitute that payload with values from ESX it fails. Create plan example is here:http://{{ move-ip-address }}:8082/#/v2api/plans/createplan We’ve tried using this same template to create a plan for ESX, but it seems to choke on the network identification section with a return code of {'ApiVersion': '2.0.0', 'Code': 20512, 'Message': "Invalid Network Mapping for VM 'NX-TEST'. Ensure sufficient user permissions on source environment to fetch network information.", 'State': 'Error'}(we have validate permissions) This appears to be the part of the payload that it doesn’t like:From the AWS example: "Networks": [            {                "SourceID": "vpc-8e1c3de7",                "TargetUUID": "343eaa8f-a251-4ec0-8ede-729c97f7cddc"            } We’ve substituted these AWS specific

NCC check giving you warning that /home space usage is above the threshold(75%) and now you’re worried how will it affect your production and what all files and directories can you safely delete. Let us guide you through the steps to safely reduce the space usage of /home directory in the CVM. Before let us understand why you’re receiving this warning.Nutanix reserves space in the SSD under /home for its infrastructure and is capped at 40GB, and sometimes it is possible to run low on the space usage and triggering an alert.IMPORTANT NOTE → DO NOT treat the Nutanix CVM (Controller VM) as a normal Linux machine. DO NOT perform "rm -rf /home" on any of the CVMs. It could lead to data loss scenarios. Contact Nutanix Support in case you have any doubts.Now that we got that warning noted on a serious note, let us answer the question :  How can we reduce space usage? First, you need to get an idea of space usage.You can run the following script to parse the usage of /home partition and give u

We have shared a post on upgrade preparations and considerations. What now? When mapping upgrades it is only sensible to account for Nutanix Files as part of the process. What really happens once you click that button?First, the pre-upgrade checks will run to make sure that the cluster is able to be upgraded. If any of the pre-upgrade checks fail, you will see information about this in Prism and the actual File Server upgrade will not start. Users will have to click "Back to Versions" and start the upgrade again after the issue reported by the pre-checks is resolved. Once the File Server upgrade beings, each File Server VM is upgraded one-at-a-time onto the new Nutanix Files version. While an FSVM is down for the upgrade, users connected to shares hosted by this node may experience a loss of connectivity for a duration of roughly 20-30 seconds. After this short period, another FSVM will pick-up on hosting those shares, and users will regain access to their files. After each FSVM comple

 You might have noticed vCenter alarms regarding CVM memory usage being high,  and when you look at Prism console for the CVM, you will see it reports 100% but no prism alert will has posed up.This is a known visual artifact with passthrough VMs that could be bypassed by creating a customize alarm in vCetner for VM memory usage and apply it to all other VMs or to the folders containing the VMs. Disabling the builtin vCenter alarms in conjunction with enabling this customized alarm can by pass the alarm reported for VCM while continue reporting any VM high memory usage. For better understanding of this issue and its by pass please review the KB 4465 in your nutanix portal.  

What is the color of your Cluster Health Heart? We use the following stoplight style color code to report the quick view of the cluster health, in the form of a color coded heart.    Cluster Healthy     Cluster has at least one Warning Alert     Cluster has at least one Critical Alert  To view the specific alert(s), on the Health Dashboard click on any of the selections from the Home Dashboard, or click on the Heart directly to be taken to the Health Dashboard overview. Selection Options:Remote Sites Hosts Services Protection Domains …Once you have selected a specific Alert to review, you will have several options for the Alert.Run Check Turn Check Off Alert Policy ScheduleMake a note of the Alert name, and locate the Alert ID by searching for the Alert name in the Cluster Settings, Alert Policies view.  False Positive Alerts Occasionally there will be an alert that will inaccurately show a warning or failure. When this occurs there are a few options to correct

While much is shared and posted about LACP configuration in AOS* the questions “How?” remains open. Let’s take a look at the workflow:Connect to CVM via SSH. Make sure you are connected to correct CVM by checking its name and IP. Follow steps from KB 2852 to verify cluster health. Do not proceed if cluster cannot tolerate failure of at least 1 node. Put the node and CVM in the maintenance mode. Connect to host via IPMI, as LACP configuration process might cause network disconnect. Perform required configuration steps (enable/disable LACP). Once configuration is completed, make sure both host and CVM are accessible via network. Please also make sure that all NICs in bond are operational, by shutting down links one by one and verifying connectivity. If all tests are successfully completed remove CVM and node from maintenance mode.For detailed instructions as well as commands examples please refer to KB-3263.For complete command reference Acropolis Command-Line Interface (aCLI).* For more

Hi guys, I'm somewhat new to Nutanix and I was curious if there was a powershell command that will allow you to set the project for a VM. Essentially I want to use scripts to deploy VM's and then when the VM is deployed move it into a project so we can track resources. The deployment part of this is easy enough, but nothing in powershell seems to indicate it can even do this. Is this something that can even be done? I really like the powershell integration, and I really like the SSP Prism Central and Projects. I'd really really like to be able to use both of these together. Thanks

If you already have a functioning “Syslog Server” and you would like to forward cluster logs to it, you can follow instructions in:“https://portal.nutanix.com/#/page/docs/details?targetId=Advanced-Admin-AOS-v511:set-rsyslog-config-c.html”However, presently (as of fall of 2019) the activity entities like Alerts/Events/Audits in prism central cannot be redirected to remote syslog servers. This can be changed in future releases of PC and AOS will be reflected in Release notes.  

Let’s say you have Nutanix cluster with 24 CPU cores and 2 sockets and now you’re confused regarding the terminology.  vCPU and cores per CPU and how to provision CPU to a Virtual Machine confusing you? Let’s break the terminology down in simple terms!In the world of Hardware, we have sockets and cores. In a host, there would be 2 sockets(or CPU) and 12 cores in each socket, resulting in 24 cores.So what is a vCPU?vCPU corresponds to the number of sockets for the VM. Cores per vCPU correspond to cores in a socket, so in conclusion, if you have provisioned your VM with the following configuration:2  vCPU 4 core per vCPUIn this scenario, your VM would have 2 sockets and 8 cores in total.How can I provision my vCPU, is there a guide or documentation regarding it?Absolutely yes, please give the following article a readCPU Configuration So is there a way to overprovision my CPU?Absolutely yes, please give the following article a readCPU Oversubscription 

"cluster -f destroy" does not help. This is a new cluster, but during one click ESXi upgrade, tasks for stuck and now nothing can happen. I am fed up with tasks getting stuck and not completing, I would like to destroy the cluster and individually update ESXi on each node. We are runing XC740xd-12

Is there a KB or documentation providing the JSON format and any additional things that may be coded in? For example, in going through the install.nutanix.com portal to generate the JSON file it doesn't ask for NTP server of the hypervisor. In looking at the file, though, there's this line: "hypervisor_nameserver": "8.8.8.8", I'd like to have our Nutanix deployments in code as much as possible (right now we're looking to various scripts for vSphere configurations). Being able to configure as much as possible up front and possibly make this a template for future deployments.
