It can sometimes be confusing as to which network port(s) a Nutanix product or service uses. Also, this information can often be helpful when configuring network security or firewall appliances. For the various Nutanix products and services, a handy list of ports, services, their respective protocols, and a simple description of each can be found in the Port Reference documentation of the Portal. This list is conveniently divided into sections corresponding to each Nutanix product or service. Also, specifically regarding the configuration of network firewalls, a recommendation regarding the specific ports configuration can be found within the Recommendation on Firewall Ports Config knowledge base article.

 When imaging fails for one or more nodes in the cluster, the progress bar turns red and a red check appears next to the hypervisor address field for any node that was not imaged successfully. Possible reasons for a failure include the following: A type of failure was detected. Check connectivity to the IPMI (bare-metal workflow). There are network connectivity issues such as the following: The connection is dropping intermittently. If intermittent failures persist, look for conflicting IPs. [Hyper-V only] SAMBA service is not running. If Hyper-V displays a warning that it failed to mount the install share, restart SAMBA with the command "sudo service smb restart". Foundation ran out of disk space during the hypervisor or Phoenix preparation phase. Free up some space by deleting unwanted ISO images. In addition, a Foundation crash could leave a /tmp/tmp* directory that contains a copy of an ISO image that you can unmount (if necessary) and delete. Foundation requires 9 GB

How do i change the name of an ESXI host and CVM in a Nutanix cluster?

I haven’t noticed any messages or communications regarding the recent log4j vulnerability (CVE-2021-44228). Does Nutanix have some formal announcement for customers on the status of this threat as it relates to their product portfolio? 

Hello, We have an old NX-1050 and I’m wondering what is the recommended AOS, Foundation, ESXi for this? I cannot find this model in the Compatibility Matrix website. Thanks!

Hi Support,I have connect FO cable from switch to SFP Port in Nutanix, but in SFP led indicator is not ON, can you help ?Thanks.

I installed a new VM with Windows Server 2022 for testing and when I try to connect through RDP it works fine for 10 seconds and then I get a frozen screen and no response. Can you tell why is that?

You can prepare and migrate VMs by using Move once the Move VM is deployed successfully. The steps involved during the entire migration process are as follows: Log on to the Move UI. Add environments for migration.For more information, refer to Adding Environment section for specific environments. Create a migration plan.For more information, refer to Creating Migration Plan section for the specific source and target. Prepare VMs automatically or manually.For more information, refer to Preparing VMs Manually and Preparing VMs Automatically section for the specific source and target. Perform test migration or cutover for migration in target environment.For more information, refer to Creating a Test Capable Migration Plan or Performing Cutover section for the specific source and target. Manage migration plans.For more information, refer to Environments and Migration Plan Management. Note: Before you migrate VMs, Move does not detect whether the source VMs have security construc

 Leap protects your guest VMs and orchestrates their disaster recovery (DR) to other Nutanix clusters when events causing service disruption occur at the primary availability zone (site). For protection of your guest VMs, protection policies with Asynchronous, NearSync, or Synchronous replication schedules generate and replicate recovery points to other on-prem availability zones (sites). Recovery plans orchestrate DR from the replicated recovery points to other Nutanix clusters at the same or different on-prem sites.Protection policies create a recovery point—and set its expiry time—in every iteration of the specified time period (RPO). For example, the policy creates a recovery point every 1 hour for an RPO schedule of 1 hour. The recovery point expires at its designated expiry time based on the retention policy. If there is a prolonged outage at a site, the Nutanix cluster retains the last recovery point to ensure you do not lose all the recovery points. For NearSync replication (li

Just wondering if i need to convert the thick disk to thin provision disk prior to the migration process from VMware to Nutanix.

The following warning occurred to customer Nutanix.WARN: Cluster cannot tolerate 1 node failure.As a result of the search, we found the following:impact Cluster can not tolerate single node (RF2) or two node (RF3) failure and guarantee available storage to provide data redundancy.The usage warning is 26.93 TiB of the 26.41 TiB recommended usage.The question here is, if one out of four nodes fails,Is it still possible to operate with RF1?Or will the cluster hang up?

The Nutanix AOS/AHV was installed on the DX equipment, and the ISCSI Data Services IP was also set up. The Volume Group tab and create Volume Group  are not visible in the Prism - Storage - Table.AOS version is 5.20.xIs Volume Group not supported for DX equipment? Or do I need another setting after AOS 5.20?

Hello Team,Hope your are all doing well  We need to size a New Nutanix Cluster for Disaster Recovery purposes of an existing cluster (04 x NX-8155-G7 with AHV).Before that, we need to scale the Existing platform by adding more compute ressources to support additionnal workloads. We were able to do it easily : we used a Scenario in Prism Central and added the workloads and clicked on the “Recommend” Button (please see pic below) :  Now, we are not able to do the following :Size the additionnal storage related to retention of local snapshots (for the Production Cluster) Size the Cluster of the DR Site : We used Nutanix collector to collect performance of the existing platform and next we exported the Excel Output file and imported it to Nutanix Sizer. We faced from the following :We are not able to inject the additionnal Workloads for the Production cluster We are not able to add the addtionnal storage related to retention of remote snapshots.Please do you have any idea to correctly size

Hello everybody, I noticed that application consistent VM snapshots of e.g. Windows 10 Pro VMs with NGT enabled and installed in the VM and verified with ‘ncli ngt list’ doesn’t work and results in the following alert… VSS snapshot is not supported for the VM 'TEST-VM', because VSS software is not installed. and … VSS is enabled but VSS software or pre_freeze/post_thaw scripts are not installed on the guest VM(s) TEST-VM protected by TEST-VM. Using a Windows Server 2016 VM with the respective Protection Domain generates application consistent Nutanix VM snapshots. With Windows 10 VMs it won’t work. Verified in 2 different Nutanix clusters. Clusters are equipped with AOS 5.15.4 LTS version. Nowhere I could find a hint, that Windows 10 VMs are not supported. Regards,Didi7 

Has anyone used Ansible for Automating Nutanix tasks. Can someone share some examples please.
