Deployment Success

 Hello. I have a question about the RF2 function.Currently, it is composed of 4 nodes and RF2 as a cluster.As far as I know, RF2 has 1 node fail.If so, shouldn't the Data Resiliency Status drop to Fail?However, although one node has failed, the Data Resiliency Status is still OK.In fact, the CPU, Memory, and Storage usage in the current cluster is low.Currently only 3 nodes are active CPU is 20% Memory is 40% Storage is 18.5%.Why is the Data Resiliency Status Ok?Is there any problem with the service even if one more node is currently turned off?Or will the cluster die if 1 more Node dies?If you don't die, I want to know why.

Hi.  Prism -> Data Protection -> EventGroups of Async DR run backups only once every Dawn.However, if check the event, I will see several messages per group.If there is a ‘Search’ group, several messages are generated for the 'Search' snapshot in the event.Each has a different time.(AM and PM). How can you explain this process? Thank you.

HelloThank you always for your help.I'd like to update the Nutanix firmware and bios.I'm trying to use LCM.Finish configuring the LCM Darksite Web server.The update list does not appear after LCM registration. We used the latest dark site LCM and nx firmware bundle provided by Nutanix. lcm_dark_site_bundle_2.3.4.1.21375.tar.gzlcm_darksite_firmware_nx_1.6.0.tar What's the problem? 

Hello everyone!I‘m running the CE on an SuperMicro Server. 1 SSD, 2 HDD 4TB. Everything was working like a charm.last week one HDD was taken offline due to smart…Hades.out quoted „Disk model HGST HDN724040AL not found in hcl.json. Running the default short test“After replacing the broken Harddrive and booting the Cum is not responding anymore.ssh nutanix@192.168.5.2 causes a „no route to host“any Ideas are welcome!Thanks Mike

I have a 3 node AHV cluster that uses 2x200GB SSD + 2x6GB HDD disks for each node. Would it be possible to add nodes to this cluster that uses 2x480GB SSD + 2x6GB HDD disks?Option is to first upgrade the 200GB SSD disks to 480GB to align all nodes to the same hardware. Maybe there is some gain in that?

Hello All, I have three NUTNANIX Cluster with below AOS versions. Are any one below is End of life ? AOS                  (updated to version 5.15.2LTS) AOS                  (updated to version 5.10.11.1.LTS) AOS                  (updated to version 5.10.11.1.LTS)

Storage ContainersA storage container is a subset of available storage within a storage pool (see Creating a Storage Container). Storage containers are created within a storage pool to hold virtual disks (vDisks) used by virtual machines.CompressionYou can enable compression on a storage container. Compression can save physical storage space and improve I/O bandwidth and memory usage—which may have a positive impact on overall system performance.Inline compression will compress sequential streams of data or large I/O sizes (>64K) when written to the Extent Store (SSD + HDD).Off

Executive SummaryThis document makes recommendations for designing, optimizing, and scaling Microsoft SQL Server deployments on the Nutanix enterprise cloud. Historically, it has been a challenge to virtualize SQL Server because of the high cost of traditional virtualization stacks and the impact that a SAN-based architecture can have on performance. Businesses and their IT departments have constantly fought to balance cost, operational simplicity, and consistent predictable performance.Nutanix removes many of these challenges and makes virtualizing a business-critical application such as SQL Server much e

Nutanix platforms use a baseboard management controller (BMC) and basic input/output system (BIOS) to control the motherboard.The Nutanix BIOS contains optimized power management settings by default. Please do not change Power Management Configuration settings in the BIOS. Nutanix does not support custom power management configurations, and changing the power management settings in the BIOS can cause unpredictable behavior.Procedures updating the BMC and BIOS:1. Upgrade through LCM2. Manual UpgradeBMC: Nutanix BMC Manual Upgrade GuideBIOS: Nutanix BIOS Manual Upgrade GuideNote: Always upgrade BMC before BIOS

Looking on OS supported to migrate with Nutanix Move v3.6.0 I see CentOS 8.2 as supported but when I add a CentOS 8.2.2004 VM to be migrated from ESXi 6.7u2 to AHV 20170830.434 I get this warning:This VM is not on the AHV supported OS list. To proceed with migrating this VM, please be sure to bypass guest operations and take care of installing AHV device drivers separately. This VM has a guest OS which is not supported on ESXi. Please remove the vm from the migration plan if migrating to ESXi.Is this expected?

Hi,Unbale to show “VM clone” option in PC 2020.9.01 while creating the customer roles in PC but same option is vaibale on super admin & project admin roles.

Many users are unaware that network traffic can be segmented (or separated) within a Nutanix cluster for various functions or purposes. For example, backplane traffic can be separated from Management-Plane Traffic so as to allow for even greater available bandwidth for the backplane traffic. Further, as another example, DMZ related traffic could be isolated to specific host uplinks. The four primary means of network segmentation are the following:Isolating Backplane Traffic by using VLANs (Logical Segmentation) Isolating Backplane Traffic Physically (Physical Segmentation) Isolating Service-Specific Traffic Isolating Stargate-to-Stargate traffic over RDMATo note, certain means of segmentation are limited to certain hypervisor versions. For example, the segmentation of management and backplane traffic is supported across the AHV, ESX and Hyper-V (Hyper-V offering logical segmentation only) hypervisors, while service-specific segment

Nutanix VirtIO includes device drivers specifically used by Windows VMs hosted in the Nutanix environment to enhance their stability and performance. This concept is very similar to VMware Tools for ESXi environments.The VirtIO bundles various drivers including:Balloon Driver Ethernet Adapter RNG Device SCSI pass-through controller Serial Driver SCSI ControllerThe VirtIO package is found on the Support Portal under AHV (please select “VirtIO” from the corresponding drop-down menu).To note, the device driver versions contained within the various available Nutanix VirtIO packages may be the same if there have been no updates for the drivers between the package releases. To correlate the driver versions associated with each VirtIO package release, please reference

AHV hosts in cluster running AOS 5.18 or newer may become non-schedulable if bridge configuration across cluster nodes is not consistent. What is a non-schedulable node?A non-schedulable node is used to increase data storage on your Nutanix cluster and does not run any guest VMs on that node.To check if this situation exists on your cluster and to fix the issue, check KB-10217. 

Hi teams, can i create 3 node cluster with 2 different FC SFP+ switch 10gb because my port is limited? between switch i using FC SFP+ 10gb link. i think the first impact is latency between node, please give me suggestion using this topology  

Nutanix AHV uses Open vSwitch(OVS) to connect to the CVM, the hypervisor and the user VMs to each other and to the physical network on each node. The CVM manages the OVS inside the AHV host. Since the OVS is an open source software switch that behaves like a layer-2 learning switch, it maintains a MAC address table. Each AHV server maintains an OVS instance, managed as a single logical switch through Prism. Bonds:When multiple uplinks are used they are added to a bond acting as a single logical interface, to which the bridge is connected. Open vSwitch (OVS) does not support bonds with single uplink and as workaround we directly connect bridge to single uplink.

Hi there.  I’m trying to plan an upgrade on our nutanix clusters from VMWare 6.5 to either 6.7 or 7.0 and I’m having a bit of a struggle figuring out the compatibility of the different VMWare versions along with our Nutanix clusters. We have two Nutanix clusters, our main site is a 7-node cluster with 5 Gen5 nodes and 2 Gen7 nodes.  Our remote data center is a 6 node cluster with all Gen 6 hardware.Our main site is running AOS 5.10.5 LTS and our remote datacenter was just recently upgraded to 5.15.2 LTS in preparation for the vmware upgrade.  I plan on upgrading our main site to the same AOS version of 5.15.2 LTS.Where I have an issue is that when running the VMWare Assessment Tool (VSAT) I keep seeing notifications on each cluster that certain nodes may not be compatible with VMWare 6.7 or 7.0 because of various devices that “May not be supported” yet say things like “is certified but current driver (ixgbe) is not supported”.  In some cases the same exac

Manual license selection allows the customer to select specific licenses available in the customer account and apply the selected licenses to the cluster. This feature can be used when: Mixing license types (e.g., Life-of-Device and Capacity Based Licensing) in a single cluster Selecting term licenses with specific expiration dates Selecting licenses tagged for specific use cases (e.g., owned by a particular organization) Manual license selection is available as an option to license products on Prism Element and Prism Central.  Where is the Manual License selection option?You see it on the portal’s ‘Manage licenses’ page displayed after .csf file from Prism (PC or PE appropriately) is uploaded. When ‘Select License’  is selected on each card, The pop-up has a ‘manually manage licenses’ option.How to access ‘manually manage licenses’ option

Hello All,I have recently deployed Prism Central and I am trying to give team members access via their AD accounts. I have went through the roles and discovered I cannot add new members to the predefined roles; however, if I duplicate the roles I can add AD users and groups to the new roles. This works for me however when I duplicate a role such as the “Super Admin” role I am warned that not all permissions are going to apply to the new role and I would need to create the new role via CLI to get these permissions. Ok fine that makes some sense. But where is the documentation on how to do that? Can someone point me to the documentation to perform these role creation tasks via CLI?Thanks, Scott

Hi all,Running AOS 5.10.5, i have changed my cluster from RF2 to RF3, including my main container and the “SelfServiceContainer”,however a week after the change I’m still seeing this error regarding extent groups,I believe that this is due to NutanixManagementShare still being RF2 (with no ability to change it, since its a systemmanaged container), or is there some other reason?

Hi ! Everyone,Does anyone know that Nutanix G7 Model has two built-in M.2 SSDs,is it possible to do Raid 1?How to do it? Thanks
