Hi All, With the VM PowerShell module for intelligent operations, I have a few questions.For the path to the .PS1 file, can I use an SMB (Nutanix) share or does it have to be a local share  already mapped to the VM?The account in question would have access both to the VM and the SMB share

when i’m trying to schedule  the NCp-MCI exam i get this error “The time slot reservation has expired, please select another time slot.”

Hi Guys,  I have a technical question for implementing multiple site into single site as a DR location using sync repository where RPO 0.Thank you for answering this question. Regards,Andreas Kuncoro 

Hi all,As part of the planned replacement of our current Nutanix cluster later this year, we are reviewing the network infrastructure requirements for the new deployment.Since a large portion of our network is already built on Ubiquiti switching, I would like to evaluate whether the Ubiquiti Enterprise Campus Aggregation Switches would be a suitable platform for the new cluster.Based on the published specifications, these switches appear to meet the required connectivity and performance criteria. Before proceeding further, I would appreciate any feedback regarding their suitability for a Nutanix environment, particularly with respect to redundancy, high availability, east-west traffic handling.Has anyone deployed or validated these switches in a similar virtualization or hyperconverged infrastructure environment?Thanks in advance for your insights.Kind regards,Erik

We recently enabled Intelligent Operations. We now have a critical alert saying that “Small Prism Central does not support currently enabled services. Please scale up PC to Large variant.” Before I pull the trigger and scale up to ‘Large’, I need to know if that has any effect on our licensing costs. We are a new Nutanix user (April). Our current licensing is good until Aug 2030. 

Hi Team,We would like to seek clarification regarding the storage configuration for the QRadar Event Processor (EP) instances.As per the current design, two QRadar Event Processor (EP) instances and two Event Collector (EC) instances are planned for deployment. The EP instances will be deployed on RHEL virtual machines.Our understanding is that, after the VM deployment, a Nutanix Volume Group (VG) may need to be created and presented as shared storage to both EP VMs to support an Active-Passive configuration.Could you please confirm whether a common/shared Nutanix Volume Group can be attached to both EP VMs for this purpose? If supported, we would appreciate your guidance on the recommended approach for configuring and presenting the shared storage to both VMs. We are looking for your acknoweldgement.

We are using the Data Protection v4.1 API compute-changed-regions endpoint from Prism Central 7.5 (AOS 11.0.0.1) to retrieve changed regions for VM recovery points.For most VMs, the workflow completes successfully. However, for VMs with large changed data disks, the API consistently fails with:401 UNAUTHORIZEDThe failure occurs approximately 15 minutes after the operation starts.Our current steps are:compute-changed-regions is invoked successfully for cluster prism element API - api/dataprotection/v4.1/content/recovery-points/{recoveryPointExtId}/vm-recovery-points/{vmRecoveryPointExtId}/disk-recovery-points/{extId}/$actions/compute-changed-regions Nutanix begins computing changed regions. The VM disks are highly fragmented and may contain a very large number of changed extents. Results are returned through pagination. The client continues fetching paginated results. Total processing time exceeds approximately 15 minutes. A subsequent page retrieval request returns 401 UNAUTHORIZED.Add

Hello, I have downloaded and installed Nutanix CE with AOS rev. 6.8 yesterday.Afterwards I have updated AOS to rev .7.3.1.6, FSM to 5.3, Foundation to 5.10.4 and NCC to 5.3.0.1 via LCM successfully.However, AHV upgrade failed with error:Lcm prechecks detected 1 issue that would cause upgrade failures.Check 'test_ncc_checks' failed: test_ncc_checks: Failure while validating that all NCC pre-upgrade checks ran successfully, Error: The following ncc checks failed: host_disk_usage_check. Please refer to KB 10847 Does anyone have an idea to fix this issue?BR, Joachim

I am getting ready to deploy a new Nutanix cluster next week and am preparing my Foundation VM.  I have imported the 7.5.1.6 AOS package which then states that the minimum AHV version is 11.0.1.2-33.  I’ve then downloaded this ISO from the link direct within Foundation and imported but I then get the message that this in an unsupported Hypervisor.  I’ve updated the whitelist but the hypervisor is still showing as not in the whitelist.  Am I ok to just install or do I need to check something else?

I have a nutanix environment Running well and it is an OT Production environment. Due to some reason I want to change the Cluster Name, so before changing, I have a doubt that will cluster name change impact the virtual machine and its operation? and do I need to reboot the cluster when the cluster name is changed to new.

I am requesting the expected release date for my NCP-MCI 7.5 and NCP-BC beta exam results.As these are beta tracks,I would appreciate an estimated timeline for when scores will be finalized and reflected in the Nutanix University portal. Thanks you, 

I have encountered a roadblock while configuring LDAP and SAML authentication from the same domain for a Customer. The Customer wants that whenever a user logins , it does from SAML and whenever a service account is logging into PC , it uses LDAP. Is there a way to configure this in Prism Central?

i  have a nutanix cluster  of node with (25gb ) uplink  and LACP is configured on it . i need to to expand cluster with nodes with ( 100GB ) uplink .i prepared the new node with below configuration:1-  re-imaged the new node with same version of AOS and AHV  as the existing cluster 2-  configured the  the new node with LACP my questions:1- is there any impact  to cluster that we mix speed of network as some node work with 25g and other with 100g ?2-  in expand cluster steps the is tab of network configuration is mandatory to set its configuratiion or can skip this configuration as i configured on new node , what will happen if i skip network configuration during expand 3- how long the expand will take to expand 4 node ?

Hi When entering a workload in Sizer, there is an option to select the existing CPU.For example, let’s assume that we are planning to deploy 100 VMs, each with 4 vCores and 8 GB of memory.  If I select “Yes, but I don’t know the current processor” and then choose Default, the estimated CPU utilization is approximately 75% when configured with a 3-node cluster, each node having 2 CPUs with 32 cores.However, if I edit the workload and select “Yes, but I don’t know the current processor”, the estimated CPU utilization increases to around 110%.In other words, I am not sure which criteria I should use when performing sizing.Why does the estimated utilization differ so significantly even though the workload itself is the same?Is there any detailed guidance available for this? It may be that I have not been able to find it, so I would appreciate your assistance.

Hello Since onw month, when change some VMs, of Data Protection to Ptotection Policie, show the next alerts: VSS is enabled, but Nutanix VSS provider or pre_freeze/post_thaw scripts are not installedVSS snapshot is not supported for the VM X because VSS software is not installed.I returned some VMs to Data Protection, and the alerts did not return.Why do it pass this behavior?

How to dump Linux Extractor memory in Nke or NKP? Can I just install lime.ko manually on the Linux Nke OS or does Nutanix have its own way to get the dump file of the memory extractor?

Buenos días,He estado revisando las opciones disponibles para la segregación del tráfico de Disaster Recovery en entornos Nutanix. Según la documentación oficial (Disaster Recovery Guide), es posible crear una interfaz de red adicional dedicada para este tipo de tráfico.No obstante, me surgen algunas dudas respecto a la implementación práctica:¿Cuál sería el procedimiento recomendado (how-to) para asegurar que el tráfico de DR se enruta correctamente a través de dicha interfaz? En escenarios de fallo o degradación de red, ¿Cómo se comportaría este tráfico dedicado? Concretamente, ¿Qué impacto tendría esta configuración en un entorno con Metro Availability, especialmente en términos de resiliencia y continuidad operativa?¿Alguien ha tenido experiencia implementando este enfoque y puede compartir mejores prácticas o consideraciones a tener en cuenta?Muchas gracias de antemano por vuestra ayuda.
