Deployment Success

We have created a new vlan for windows 10 VM and I wanted to update existing network to new network. I was not able edit the existing network and choose the new one, it is grayed out. Do I need to delete and re-add new nic and choose the new network? For ESXi, you simply browse the network and select the one you want and save it.

The flash mode for VM allows to set the storage tier preference to SSD for a virtual machine or a volume group.  Without flash mode, data for a mission critical application such as a relational database can run out of the room in the SSD tier because other workloads running on the same cluster.  When this happens, the database could potentially migrate to the HDD tier. For extreme latency sensitive workloads, this migration to the HDD tier could negatively affect the read and write performance.  By default, you can use up to 25% of the cluster-wide SSD tier as flash mode space for VMs or VGs. If the data size for flash mode enabled VMs or VGs exceeds 25% of the SSD capacity, the system may down migrate the data.  Before down migration, the flash mode feature tries to preserve the excess data on the SSD tier for some reasonable amount of time so that you can take corrective actions on the cluster and bring it back to stable. To reduce flash mode usage, we can disable the flash m

Hi Buddies!I would like to know if this possible to add GPUs card on a NX-8155-G6 hardware. I know that this model doesn’t came with GPU installed, but, is it possible to add it?

In the default AHV network schema, ther’s a connection between the AHV management and the virbr0. Can you explain me the purpose of that connection and the IP adresses used ? 

As the Nutanix Life Cycle Management (LCM) platform evolves, more firmware entities are added to the module. The latest addition are the NICs associated with Nutanix hardware.Starting in LCM 2.3.4, firmware updates for Mellanox and SuperMicro NICs on AHV and ESXi are supported. Currently, Hyper-V platforms and Intel/Silicom NIC cards are not supported.For more information about this feature and software requirements, take a look at KB 10073 found on the Support Portal.

I upgrade AOS 5.15.4  and i have AHV older version I need Upgrade AHV after by LCM I Click LCM and loading… long time and show massage server error i have question  ? LCM Need access internet  ?

Hi,I would like to configure anti-afinity on on the VMs. I checked this only able to configure thru command. To configure the rules, does the VMs need to be powered down?

As Nutanix is constantly striving to be an API driven company and exposing more of its core functionality via API’s as well as improving integration with tools such as Ansible and Terraform, we hope you have been making the most of it. For example, did you know how to check the status of NGT and the NGT communication link using API’s? It is easily obtainable using the v3 REST API exposed from your Prism Central. Issue a GET request to https://<PC_IP_address>:9440/api/nutanix/v3/vms/<vm_uuid> Filter through the response to find a block similar to this.        "guest_tools": {        "nutanix_guest_tools": {          "available_version": "1.90.1",          "ngt_state": "INSTALLED",          "iso_mount_state": "MOUNTED",          "state": "ENABLED",          "version": "1.1.2",          "enabled_capability_list": [            "VSS_SNAPSHOT"          ],          "guest_os_version": "windows:64:WindowsServer2008R2Enterprise",          "is_reachable": false        }      }       

Hello, I am trying to collect some VM performance data from Prism element. I have noticed that some stats do not keep history for more than 5 minutes.   Example: controller_io_bandwidth_kBps vs. controller_read/write_io_bandwidth_kBps   GET 'https://{IP}:9440/PrismGateway/services/rest/v1/vms/{vmid}/stats/?metrics=controller_io_bandwidth_kBps&startTimeInUsecs=1589462400000000&intervalInSecs=300'   "statsSpecificResponses": [     {       "successful": true,       "message": null,       "startTimeInUsecs": 1589462400000000,       "intervalInSecs": 300,       "metric": "controller_io_bandwidth_kBps",      "values": [         8106,         5500,         8404,         5618,         12793       ]     }   ] } GET 'https://{IP}:9440/PrismGateway/services/rest/v1/vms/{vmid}/stats/?metrics=controller_read_io_bandwidth_kBps&startTimeInUsecs=1589462400000000&intervalInSecs=300' {   "statsSpecificResponses": [     {       "successful": true,       "message": null,       "startTimeIn

If the clusters are related with prism central (so I should use v3), Can i use v2 to actions like: manage NIC, Attach/Detach Disks, manage snapshots from API v2?Is recovery plans is the same as snapshots here? I want to create jobs for automatic snapshots, but I do not see thios possibility in v2I am using the same account for api v2 and v3 actions, in production environment with my own IP, it will be the same host? It is specified in API Documentation, but I want to be sure if the host for both will be the same - eg. nutanixtest.com/v2… and nutanixtest.com/v3…Thanks!

Nutanix cluster requires three nodes minimum but Nutanix also offers the option of two-node cluster. By configuring external witness VM in a separate failure domain to the configuration provides  resiliency features of a three-node cluster.Requirements: Controller VM minimum requirements: 6 vCPU and 20 GB memory Replication factor (RF): RF2 spanned over two nodes and RF4 for metadata on SSDs over two nodes. RF4 for metadata helps during a node failure scenario to quickly transition the healthy node to run in single-node mode with the metadata remaining disk fault tolerant. (Metadata in a two-node cluster is typically small, so the storage need for four copies is modest.) Drive failure effects: one node + one SSD failure (on other node) = read-only mode. Guidelines: Two-node clusters are supported only on a select set of hardware models. See KB 5943 for information about supported models. supported model The upgrade process in a two-node cluster may take longer than the usual proc

I could get a ballpark idea when the next LTS be designated. Seems like its been awhile. I would like to get off the STS train.

LCM simplifies Nutanix IT infrastructure life cycle operations by consolidating software and firmware component upgrades into a unified control plane. Prerequisites·   It's recommended to have a cluster with at least three nodes to perform a normal rolling hypervisor upgrade.·   The 2-node case isn't well supported and might require extra steps to enable rolling upgrades, like installing and configuring a Witness VM.·   The 1-node cluster upgrade is also supported but requires LCM 2.2.3 or newer. ·       LCM 2.0 is considered old and not recommended for the AHV upgrades, instead one has to use the legacy "Upgrade Software" method in "Settings".·       Starting LCM 2.2.3, AHV upgrade is supported, both single node cluster and regular cluster, but it only support el6 based AHV upgrade.·       Starting LCM 2.3, AHV upgrade is fully supported, single node, multiple nodes cluster, upgrade from el6 based AHV to el7 based AHV, el7 based AHV to el7 based AHV, UEFI el7 based AHV to UEFI el7

Using Nutanix Insights, Portal will provide this view based on Field Advisories, constant health checks, end of support equipment, etc.The Discoveries Details View provides the background, analysis, and corrective actions that can be done to remedy these issues. This will also give you the option to create a case based on the specific issue/topic.For more information, take a look at the “Discoveries Menu” in the Support Portal.

If you have cloned multiple VMs from a single VM (master VM), you can enable NGT and mount the NGT installer simultaneously on multiple VMs by using the master VM image.Before you beginEnsure the following before you perform this task: Install NGT on the master VM. Clone the required number of VMs from the master VM. Shut down the cloned VMs. Perform the following procedure to enable NGT and mount the NGT installer simultaneously on multiple VMs by using the master VM image.Note: After you perform the following procedure, you do not need to separately install NGT on the cloned VMs.Procedure For every cloned VM, log on to the Controller VM and run the following command.ncli> ngt mount vm-id=clone_vm_id Replace clone_vm_id with the ID of the cloned VM. To find the ID of the cloned VM, run ncli> vm list name="<clone-vm-name>" command. Note the value of the Id field as clone_vm_id.<ncli> vm list name="<clone-vm-name>"Id                        : 00058a81-64bb-2

The iSCSI Data Services IP address is used to provide iSCSI access to the cluster storage. It is primarily used by Nutanix Volumes, but is also leveraged by other products such as Calm, Leap, Karbon, Objects and Files. This IP address is owned by one CVM of a cluster at a time, with ownership changing among the CVMs as needed to ensure that it is always available. To note, the iSCSI Data Services IP address CVM owner does not necessarily correlate with the CVM that currently maintains Prism service leadership.To find the current CVM acting as the iSCSI Data Services IP address owner, simply obtain the IP address output from all of the CVMs (generally by using the “allssh ifconfig” command) and verify which CVM reports as having this address. To find when a ownership change has occurred, the Stargate service logs from each CVM can be filtered for entries regarding “eth0:2”.You can find more information regarding the iSCSI Data Services IP Address from the Nutanix Volumes Guide along wit

Great pleasure to say Sizer 5.0 is now liveTwo very big thingsCluster settings/cluster policy.  We always allowed you to edit the model list and set thresholds for cpu/ram etc that the cluster must meet.  Lot more now.  Mihn cpu speed.  Required networking.  Also added policy.  So you can state I want production, test/dev, or mission critical policy.  This gives you more rigor in the sizing as enforces best practicesMultiple recommendations  Sizer by default gives you the lowest cost solution.  That is there but now core optimized and storage optimized too.  So solution with more cores or more storage that fits in cost range you state.  Good to have multiple options

I know that this question has been asked in this forum a few years back but I wanted to see if the answer changed since the newer releases of AOS.  In my case, I’m running AOS version 5.15.4 LTS and found that our 7-node cluster was configured for RF3 - although most of our containers are RF2 (the exceptions being the “NutanixManagementShare: and “SelfServiceContainer” containers).Since most of our containers are only RF2 I’m not too concerned about extra overhead but was curious if AOS now supports the switchback from RF3 on the cluster. 

From the AHV Best Practices document,  live migration network is in host management network(br0).In the network segment enviroment, backplane is isolated in another network which maybe has high bandwidth, does the live migration has any change under this condition? or Live Migration network can do some setting like ESXi vmotion network?
