Deployment Success

Hi all.I’ve been trying to figure out how I can execute a PowerShell script inside a guest VM, both Linux and Microsoft, on AHV through the host but can’t find any solid information on the topic.There is a discussion called “Execute Script Inside AHV VM?” but that is only for initial configuration of the VM. I’m looking for a way to execute an arbitrary script on any running VM without having access to the VM through its default network configuration.It’s basically a hosting situation where customer VMs exist within their own isolated environments and I’m responsible for running various scripts for - among other things - joining new servers to AD, installing SQL Server, patching the OS, etc, etc.Looking at this post there seems to be a way to run scripts through NGT but when reading the Nutanix Bible that option seems to be limited to VM creati

Please consider the possibility of incorporating the existing IP scheme in the new infrastructure. If changing the IP address is the only option we can utilize a script to change the CVM IP address. You can use the external IP address reconfiguration script in the following scenarios: Change the IP addresses of the CVMs in the same subnet. Change the IP addresses of the CVMs to a new or different subnet.In this scenario, the external IP address reconfiguration script works successfully if the new subnet is configured with the required switches and the CVMs can communicate with each other in the new subnet.

We have a 15 block HPE environment built with AOS 5.15.2. we need to enable flash mode on a NVMe device (vmdk) which is presented within vSphere but cannot be seen via prism element under the VM vDisks or via ssh shell to cvm’s is this feature not currently supported? any ideas I am struggling to find much on the support portal?still unsure on this how do we pin the NVMe vmdk to the performance tier  cheers

If you have a storage container on the cluster and the name starts with a “#”, you may see this error while trying to upload an image:"Could not access the URL nfs://127.0.0.1/%23ISO_Images/.acropolis/image/106ac31b-6236-4534-a2ae-808c08bb912f: Failed to parse the file size" That happens because the URL cannot have the # in the name and it gets automatically replaced with %23. Therefore, this creates the inconsistency between the container name and the URL.To resolve the issue, rename the container and remove the # from the container name and retry the image upload.Take a look at KB-10117 for more information.Check this guide on

To verify if we have replaced DIMM on correct slot and CPU we can use the following method We can look at hardware.history file which records any replacement for example DIMM,SSD,HDD,NIC being made to that node. This file remains local to each CVM After we replace DIMM we will boot the host up Power on CVM and run following command ncc hardware_info update_hardware_info           This will update the hardware.history file present in ~/config directory and it will recognize any new replacement Open hardw

Hello,i have some questions regarding “Switch stacking”1-) Is it possible to use " 2 stacked switches " as TOR with AHV? there will be a problem if we use this configuration?2-) The best practice is to use 2 Stacked switches or 2 individual switches?We plan to use Active-Backup configuration and conect SFP to Switch1 and the other SFP to Switch2I am not a network specialist so i am not sure if both switches are stacked, and we plug 1 SFP to SW1 and the other SFP to SW2, the active passive configuration will work

Hi, I am working on an integration between Nutanix and Citrix but stuck at the moment at this point: Where in the Citrix Cloud can I find these values?Kind regardsChristian

The upgrade process for the VCSA from a major release to another is as follows:A new VCSA with a temp IP is created in the vSphere host/cluster by the upgrade process. The upgrade process migrates the config/data from the old VCSA to the new one. The Old VCSA is shutdown and the new VCSA is renamed/re-ip with the values of the old VCSA. New VCSA is then rebooted.At this point the new VCSA should have the old VCSA name and IP address.  My question for those that have done this already is, how does the Nutanix cluster Prism element reacts to this in regards to its vcenter registration? Will all this be transparent to it or will it see the new VCSA as a new device and create a duplicate entry? I assume the migration process will copy SSH keys and certs from the old VCSA to the new one so Prism won’t bat an eye, but I just wanted to confirm. 

Hello ... can anyone provide feedback on getting Network Visualization working with Cisco Nexus 9K Switches. The Nexus Series is on the Supported Switch list, but I've had a ticket open with Support for weeks and we can't get it working. https://portal.nutanix.com/#/page/docs/details?targetId=Web-Console-Guide-Prism-v510:wc-network-visualizer-supported-switches-r.html LLDP is enabled globally on the 9K, and I can populate the 9K switch info into Prism just fine. The issue is I can't get any port data. Nutanix Support is saying the issue is by default the "port-id-subtype" is set "locally-assigned", and it needs to be changed to "interface-name". The 9Ks are in ACI-Mode, not NX-OS, and no one seems to know how or where the change is made. Has anyone gotten this setup to

In the first 3 Sections we saw solutions with classical snmp monitoring, dynamic monitoring with checkmk and metrics with prometheus and grafana.No we try the windows way. A Windows Application from the german vendor “Paessler” which could be tried for free for 100 sensors (not Nodes or VMs!).We download the Package here and install.After successfull Installation we get a Browser Page on Port :8080 and a LoginPrompt with default  prtgadmin / prtgadmin.We login and create a new Host over the Menue Geräte/Geräte hinzufügen for our Nutanix Cluster:Zum Einsortieren hab ich hier “Virtuelle Systeme

The dynamic Inventory of a Hosts and the creation of Service Checks is one of the benefits of the checkmk opensource tool CheckMK. This Tool could be installed as a single Installation but it is also part OMD or Openitcockpit, which are using checkmk as an extension In my Homelab i will give a short overview of the use of checkmk with Openitcockpit with a nutanix 3 node cluser.Requirements: Enable SNMP in Prsim Centrala) Port 161/UDPb) Ein Username und Kennwörter fuer SHA und AES

Nutanix Clusters Console receives the results of the status checks performed by AWS to see the status of the instances.Status checks on AWS are performed every minute, returning a pass or a fail status. If all checks pass, the overall status of the instance is OK. If one or more checks fail, the overall status is impaired.    There are two types of status checks, system status checks, and instance status checks. System status checks monitor the AWS systems on which instance runs. Instance status checks monitor the software and network configuration of individual instances.If Nutanix Orchestrator detects that AWS has marked system status or instance status of an instance impaired, following WARNING message will be seen in the Notification Center of the Nutanix Clusters Console: More information on -

Nutanix Move is a very versatile tool which is used to migrate existing VMs, from various storage sources and hypervisors, into a Nutanix infrastructure. Many users have already enjoyed its functionality and ease-of-use.Often, users will migrate multitudes of VMs into their new Nutanix infrastructure using Move, and then either delete or forget about the Move VM itself thereafter. Later, when more VMs are sought to be migrated, users will either reinstall Move again or attempt to leverage the Move VM that remained from the previous migration.For those users leveraging an existing Move VM within their infrastructure and, as it is generally a good idea to use the latest version of Move when possible, it is possible to upgrade the Move VM to the latest available version right from its ow

Hardening is the process of securing a system by reducing its surface of vulnerability, which is larger when a system performs more functions; in principle a single-function system is more secure than a multipurpose one. Reducing available ways of attack typically includes changing default passwords, the removal of unnecessary software, unnecessary usernames or logins, and the disabling or removal of unnecessary services. There are various methods of hardening Unix and Linux systems. This may involve, among other measures, applying a patch to the kernel such as Exec Shield or PaX; closing open network ports; and setting up intrusion-detection systems, firewalls and intrusion-prevention systems. There are also hardening scripts and tools like Lynis, Bastille Linux, JASS for Solaris systems and Apache/PHP Hardener that can, for example, deactivate unneeded features in configuration files or perform various other protective measures. We can implement Securit

Application monitoring provides visibility into integrated applications by collecting application metrics using Nutanix and third-party collectors, providing a single pane of glass for both application and infrastructure data, correlating application instances with virtual infrastructure, and providing deep insights into applications performance metrics. The monitoring integrations dashboard allows you to view information about select applications, such as SQL Server instances, running in the cluster. Before you decide to enable this, there are some pre-requisites that you need to follow.  To learn more about the prerequisites, click here and for more information about Application Monitoring, check the

Using the RestAPI, we are able to pull around 300 metrics from Nutanix. Do you have a document which explains what all these metrics are, similar to the page we have for the metrics available via SNMP (https://portal.nutanix.com/page/documents/details?targetId=Web-Console-Guide-Prism-v511:man-nutanix-mib-r.html)

To start this topic, it is worth to mention the difference between the data size units. There are GBs (gigabytes) and GiBs (gibibytes). The difference is the following:GB = 1000 MBGiB = 1024 MiBSo, the difference is in binary vs decimal representation. It can be confusing, because a lot of people have never heard of gibibytes and always thought that GB is 1024 MB. In fact, it is not exactly true Why it may be confusing in Nutanix running on ESXi hypervisor?Nutanix is using MiB, GiB, TiB, etc as data size units. When you create a storage container, you get the size in binary units. For the example, i have created 2 contain

Hi, I’m looking to understand the possible values for group_member_attributes in the POST /v3/groups request. I’ve gotten some examples from debugging the Prism UI requests (e.g. “project_name”, “vm_name”), but is there a full list published somewhere? I’d looked in the API docs and had a search of the forum but couldn’t see group_member_attributes detailed - apologies if I’ve missed it. Thanks in advance.

Hi all, I tried to get the kubeconfig renewal made by Ansible with the use of the Karbon API. All is fine except for the format of the kubeconfig file. I have a lot of \n characters and some additionnal information. Is there a way of getting a correct kubeconfig file without all these or we have to clean the file in order to get it work ?For example, this is the content of the file : {"kube_config":"# -*- mode: yaml; -*-\n# vim: syntax=yaml\n#\napiVersion: v1\nkind: Config\nclusters:\n- name: xxxx-xxxx-xxxx-\n  cluster:\n    server: https://xx.xx.xx.xx:443\n    certificate-authority-data: LS0tLS1CRUdS0tCk1JSURyVENDQXBXZ0F3SUJBZ0lVWkJuMkxpWG13aURvbWVxQU5wWmY3emxoaEpjd0RRWUpLb1pJaHZjTkFRRUwKQlFBd2JURUxNQWtHQTFVRUJoTUNQ2tOaGJHbG1iM0p1YVdFeEVUQVBCZ05WQkFjVApDRk5oYmlCS2IzTmxNUkF3RGdZRFZRUUtFd2RPZFhSaGJtbDRNUlV3RXdZRFZRUUxFd3hKYm1aeVlTQkxZWEppCmIyNHhEVEFMQmdOVkJBTVRCSEp2YjNRd0hoY05NakF3TmpJeU1Ea3dNVEF3V2hjTk16QXdOakl3TURrd01UQXcKV2pCdE1Rc3dDUVlEVlFRR0V3Sl
