Is there a way to make a UEFI based vm via comandlets or the API?  This posting seems to leave those two out.  https://next.nutanix.com/prism-infrastructure-management-26/uefi-on-vms-faq-37339

Hi Folks, We have been getting alerts on memory usage from the Prism Central VM. It seems to be a known issue. So to suppress the alerts from repeatedly generating cases in our internal ticketing system I am working on setting up an automated restart when memory usage gets to 90%. I’ve written the code to do this (a mix of the Nutanix cmdlets and Rest API calls in PowerShell). It works fine when run under my own account. My account has the ‘User Admin’ role. I should also mention we map roles to AD groups. However I wish to move the scheduled job to run under the context of a  service account. The service account has been assigned a Custom Role with a single assignment ‘Update VM Power State’         I’m added the Role to my Service account user and applied it to the Prism VM (and a Test VM).     I’m wondering if I need to grant more permissions as I am getting an error   Access is deniedSet-NTNXVMPowerState : The remote server returned an error: (403) Forbidden.

I am looking at a way to programmaticly add a Directory User to a Project, as part of a blueprint.  Blueprint has a macro for the user identity in question.  I just need to be able to set that user as a Project User, and ultimately VM Owner.  I have the VM Owner, but they need to be a prior Project User, and adding domain users, to project users, sounds like a bad idea.

  Microsoft has enabled LDAP channel binding and LDAP signing in March this year in Active Directory Windows Servers architecture. Nutanix recommends changing Prism Authentication from LDAP on port 389 to LDAPS on ports 636 or an SSL encrypted port 3269. Two things to note with the process are: changing just the port number is not enough because the LDAP protocol also needs to change to LDAPS Prism self-signed certificates work with the LDAPS so no extra hassle The process is straightforward and only requires a change of a URL syntax in Prism settings.   For instructions and verification steps see:KB-9029 Changing LDAP port 389 authentication to Secure LDAP (LDAPS) ports 636 or 3269.   More on LDAP:KB-3363 Prism: Troubleshooting LDAP and AD Issues for Prism Log On   For more Information about Microsoft change:2020 LDAP channel binding and LDAP signing requirements for Windows.

  At Nutanix we obsess over customer experience. Form the purchase through transition to support - all things, but also your experience as an administrator is part of our obsession. We believe that you have other things to do than to spend countless hours on achieving something that can be achieved with less effort. 1-Click upgrade is a feature that is designed to streamline the upgrade process and save your time. Sadly nothing is perfect and things go out of order. If the 1-click upgrade fails with the error below some troubleshooting is due. release-api.nutanix.com could not be reached during 1-Click Upgrade Reaching a Web page is like reaching an IP address but with an extra layer of FQDN resolution by DNS hence the troubleshooting logic looks like this: Verify that the FQDN resolution is successful Inspect proxy settings Verify correct settings are applied if using Transparent Proxy Confirm that the firewall settings allow the traffic both ways Review logs and restart the

After connecting my Cluster to Prism Central I see some VMs in Prism Central that are not existing anymore in the Cluster and I cannot find a way to remove them. Here is an example: These VMs are already deleted in the clusterIn Prism these VMs are not visibleIs there a way to delete these VMs from PC? I already tried to remove the cluster from PC, run the cleanup scripts and connect to PC again (even to a new installed one), but it did not help.

We're new to using Calm for automation/orchestration and I'm looking to get additional information/guidance on how we can leverage the Nutanix REST APIs during our virtual workload PreCreate/PostDelete tasks. I under how to work with the HTTP Task itself, but I'm not quite sure how to chain them together in such a way that it would work. They function as I would want individually, via the Test functionality for each HTTP Task.The first three cases we're trying to get to work to get our feet wet include: During Package Install, leverage Prism Central REST APIv3 vms to GET the complete spec of the newly created VM; modify that Response to update the Description; and set (PUT) the updated Spec with the modified Description as desired. During Package Install, graceful shutdown of the new virtual workload and removal of the second CD-ROM drive that is added (ide.3) to hold the 'unattend.xml' file. During Package Install, leverage Prism Element REST APIv2 protection_domains/{nam

So you kicked off the one-click Prism Central deployment and left your desk to get a coffee. Now you are back and see it has failed. Wonder what could have happened? Here’s a list of common issues you could take a look at before engaging our world-class Support!   The deployed Prism Central is not compatible with the underlying cluster AOS.  Check interoperability on the support portal   Network issues  - If the PC is deployed on a different subnet/VLAN and the CVM is unable to reach the PC network. You would see the PC VM has been created but since genesis service on the PC cannot be reached, the task eventually times out/fails. You could also have firewall rules in place preventing bidirectional communication on ports 80, 9440, 2100. This KB should help you with that.   If there is an existing PC binary or metadata file for deployment on a Prism Element cluster, the upgrade may fail with an error indicating the software already exists in the cluster.  The b

When managing large scale environments, it is important to have a central source of synchronised data. As is that data is not very useful. To become readable and interpretable information the data must be laid out and aggregated in a particular way. Furthermore, tracking the progression of stats overtime is, perhaps, a more valuable source of information about the environment. Reporting is one of many useful features that Prism Central provides to help you make the most of your HCI environment. You can be very granular in what you choose to include from VMs all the way to clusters. Graphs and tables. You can customise the appearance of the report with brand logos. More importantly, you can schedule it to run and be sent regularly for review via email. You can also group entities in the groups and review their performance as one. What if you wanted to look at performance or resources utilisation of VMs grouped by applications rather than one by one? You can. Remember, there are also

Prism Central allows you to configure syslog monitoring which forwards system logs(API Audit, Audit and Flow logs) from the registered clusters to an external syslog server   There are some consideration we need to be aware of:   As the logs are forwarded form Controller VM(CVM). It displays IP address of CVM We can only configure one rsyslog server  Protocols which are supported are TCP and UDP Logs can also be forwarded to a remote syslog server using Reliable Event Logging Protocol (RELP).   Configuration of the syslog server is very simple.  Login to Prim Central and go to settings       2.click syslog server   3. Add the external syslog server name, IP address and port     4. All the registered clusters will now forward logs to syslog server   For more details on syslog please refer following documents   https://portal.nutanix.com/page/documents/details/?targetId=Prism-Central-Guide-Prism-v5_16%3Amul-syslog-server-configure-pc-t.html

A few questions on logs collection and rotation today. Are the logs deleted automatically? Yes, they are! With newer AOS versions log bundles older than seven days are purged from CVM automatically.   Is there a way to check /home space usage of a CVM from the Prism Unfortunately no. Please refer to solution section KB-NCC - Health Check command fails with error "No space left on device" NCC - Health Check command fails with error "No space left on device" for the command on how to check the space usage.   Is there a difference between log collection triggered from the Prism as opposed to the same from the CLI. The end result is the same however CLI method allows for more flexibility due to additional options. From NCC 3.7.1 onwards, use of the Logbay utility for log collection is recommended instead of log_collector due to performance, usability and feature enhancements. Logbay eliminates performance issues that sometimes are observed with log_collector. If you have not yet upg

Anyone know if it is possible to create a scheduled task in AHV to migrate a VM to another hosts in an AHV Cluster?

Hi, im new in nutanix. I have 1 cluster with 2 blocks and 4 nodes here. Everything went fine until im seeing no detail in memory usage unlike other of my VMs. How can this happen? I need my memory usage detail to monitor any of my VMs with high resource usage. Any Solution to solve this off?  

You may want to unregister a cluster from Prism Central for various reasons. Currently, we don’t provide this option via the Prism GUI as to reduce the risk of accidentally unregistering a cluster. In recent releases, numerous key features such as micro-segmentation, CALM, Self-Service portal, Karbon etc require Prism Central and unregistration could result in these services being unavailable.    However, if you still wish to unregister a cluster either because the cluster is decommissioned or to deploy a new PC, these are the high-level steps you would have to follow.   SSH into any CVM in the cluster that needs to be unregistered and run the below command. ncli multicluster remove-from-multicluster external-ip-address-or-svm-ips=<PC_IP_ADDRESS> username=<PC_USERNAME> password=<PC_PASSWORD> force=true parameters: PC_IP_ADDRESS, PC_USERNAME, PC_PASSWORD   SSH into the Prism Central VM and run the unregistration script. python /home/nutanix/bin/unregistration_

Whether you are troubleshooting a particular issue or you are just curious to know how a certain component (such as a VM) performs in your cluster, understanding which tools are at your disposal will allow you to save time and effectively address issues related to your workloads in your Nutanix cluster; there are two type of charts you can use to review objects, understand how they are performing and take action accordingly, I will briefly explain each one of them below. Entity charts:   It allows you to check multiple metrics from a particular object, for example checking the latency of a VM alongside with the amount of IOPS and controller latency, which is really useful when troubleshooting performance related issues.Metric charts: You can think of it as the opposite of the option above, the metric is the main object and then you can obtain information about the metric for a particular component. For example if you need to get the latency metric, you can then filter further for th

Hey Eveyone, I recently added a new 2-node cluster to my prism central. When I try to launch Prism Element from Prism Central. I get a pop massage “This action is only supported on cluster version 4.5.2 or later. Any thoughts? Prism Central: 5.11.2.1 AOS: 5.10.9.1 Foundation: 4.5.3 Thanks  

Hi forumpeople, For some reason we see different values in Storage Summary in Prism and Sizer/Storage Capacity calculator. We are dealing with an RF2 cluster here. Storage Summary shows 47.9 TiB  Yet Sizer shows 35,53 TiB and Storage Capacity calculator shows 36,05 TiB   A small difference may be due to the actual cluster having 4x2TB NVMes per each of the 5 nodes, and only 1.92 being available in Sizer/Capacity calculator, but it should not make such a critical misalignment between Prism and Sizer/Capacity calculator. What is the actual usable capacity of the cluster (with RF2, N+1)? Also, how are “CVM Overhead” values taken into account in Prism’s Storage Summary and is it part of the actual usable capacity?

USEFUL COMMANDS TO TROUBLESHOOT PE-PC CONNECTIVITY ISSUES We have lots of scenarios where you might see alerts related related to PE-PC connection failure. This generally happens when network connectivity between PE and PC clusters are disrupted due to any reasons such as PC VM being rebooted, upgrading PC cluster , network issues, HTTP proxy issues(incorrect proxy whitelists) and port issues etc.   Firstly, when does PE-PC connectivity alert is raised on PE:   1)The alert is raised when PE-PC connectivity was disrupted for at least 6 minutes as of AOS 5.10.(Prios to AOS 5.10 alert is generated at a single instance of 2 minutes) Sometimes, PE-PC connectivity checks shows red heart on Prism even, if the connectivity is fine and none of the above reasons are present. In this case i.e if you verify there are no underlying PE-PC connectivity issue present, manually reset the check. Turn the check OFF and Turn it back ON from the Health page by clicking on this check like this below. 

Within the Nutanix main infrastructure there are two main components which Administrators can use to manage their environment, those are the following: Prism Element Easy to use graphical interface to manage a single Nutanix Cluster, it exists as a service within your CVMs with one of them acting as a leader.From Prism Element you can have two different authentication methods, which are local users and Active Directory accounts. Prism Central Additional component which can be deployed as a VM to manage multiple clusters which can be horizontally and vertically scaled to suit your environment depending on how many components such as VMs and Clusters it is required to manage.From PC additional to both local users and AD accounts you can also configure SAML authentication using an identity provider.If you want to know more about the authentication types here are some additional resources you can use: Prism Element Authentication Configuration Prism Central Authentication Confi

After upgrading to the latest Prism Central, AOS, and AHV versions, I wanted to check out the storage QoS options. But after looking all over, I could not find where to do this. I asked one of my fellow Nutanix adminstrators who has the same access as I do to the same resources and he showed me where the settings can be configured. However, I don’t have this option (and a few others) when logged in with my account. Not even with the Prism Admin account. I’ve tried different browsers, clearing browser cache, different computers. Nothing. Any ideas why I can’t see these options?

Upgrade Prism Central 5.11 to 5.17  through command line

We have several AHV clusters across the WANscape all managed from Prism Central. On one AHV cluster, I created a Windows Server 2016 and a Windows Server 2019 VM from CD ISOs, patched and tweaked and these are our “Golden Images”.  I clone those and run sysprep and those are what I make new VMs from. Now I have two problems: 1.) in each cluster we have an RF2 container and an RF3 container so these VMs are bound to one or the other, and 2.) how do I get these to other clusters? To address the differing containers, I end up using the image service (create image of the disks and create new VM from those disks).  But now I’m wasting storage because I’m keeping copies of the same VM on two different containers. To address the differing clusters, I was thinking about setting up Protection Domains and letting Nutanix replicate them to each cluster.  They would only get updated once or twice per month for Windows patches.  Doing it this way would allow me to control replication schedule a

Did you know that you can automatically send Nutanix Alerts to ServiceNow? Using X-Play's out of box Send Alerts to ServiceNow action along with either the Alert or new Alerts Matching Criteria trigger, makes it simple to create a Playbook to automatically send Alerts matching designated criteria to the ServiceNow events table. Here is a quick video illustrating how to send all Alerts in the system directly to ServiceNow.      

Last week, we summarized what is new in Prism 5.17 with a short demo. You may be wondering how you can create the same demo and how long would it take. Today, we will not only introduce new triggers and actions but also walk through how you can create the same demo.
