Deployment Success

For a node to join a Nutanix cluster, it must have a hypervisor and AOS combination that Nutanix supports. AOS is the operating system of the Nutanix Controller VM, which is a VM that must be running in the hypervisor to provide Nutanix-specific functionality. Find the complete list of supported hypervisor/AOS combinations at https://portal.nutanix.com/page/documents/compatibility-matrixFoundation is the official deployment software of Nutanix. Foundation allows you to configure a pre-imaged node, or image a node with a hypervisor and an AOS of your choice. Foundation also allows you to form a cluster out of nodes whose hypervisor and AOS versions are the same, with or with

We have Lenovo HX (3752) installed with 3 nodes pre-bundled with AHV and AOS. The onsite technician configured IPMI (XCC) and we are now able to login to the XCC and also able to access the console (AHV). I wanted to do the following,Change the AHV IP address from the console (commands)? Know the AHV version and its default IPs/current IPs from the console? Connect/ssh to CVM and change the CVM IPs? Create Cluster of 3 nodes

HyperVisor - ESXi 6.7U3Mostly Windows VMsI’m sure there’s good reason for this and it's probably to do with the way SQL handles memory but when I check the memory usage from Prism or Prism Central for a VM that’s running SQL it’s not accurately reflecting what the VM is actually using.  For example, from within the VM if I fire up task manager or even perfmon it will report the memory usage at say 95% whereas from Prism it reports the VM as using 25%.I need to generate a report for a collection of SQL VMs and application servers but I think for the SQL VMs I'm going to have to provide perfmon screenshots or something.Can anyone explain to me in simple terms why this is happening?

When I run the following  <:~$ ncli multicluster get-cluster-state I get this output, Cluster Id                : bff29593-35c0-4f5a-804f-257374c3e979     Cluster Name              : Unnamed     Is Multicluster           : true     Controller VM IP Addre... : [10.250.130.151]     External or Masqueradi... :     Controller VM NAT IP A... :     Marked for Removal        : false     Remote Connection Exists  : true   Question is how can I change Cluster Name to something other than Unamed???

With AHV-20190916.189, Nutanix supports Directly Attached Volume Groups in a Guest VM Cluster. On AHV clusters, you can create a guest VM cluster by directly attaching a volume group to guest VMs.After you attach a volume group to guest VMs, vDisks appear as SCSI devices to the guest operating system and you do not need to set up any in-guest connections when you are creating a guest cluster. If you directly attach volume groups to guest VMs, you can seamlessly share vDisks across VMs in the guest cluster.You can directly attach a volume group to guest VMs to create the following guest clusters:1. Microsoft Failover Cluster (MSFT)2. Red Hat Enterprise Linux (RHEL) Cluster For more details, refer to following:Guest VM Cluster Configuration (AHV

Hello and thank you for the advice, I administer 1 block, 3 node cluster on NX-1065-G4 hardware, power is 110v. Following is the software versions:Version 5.10.10.1 LTS - Pro LicenseNCC Version: 3.9.4.1LCM Version: 2.3.2.3.20029AHV Version: 20170830.396HA reservation is enabled Can you please describe, or link to a KB which will help me understand, how a node failure will cause VM fail-over to another node? For instance, if node 1 fails, how and when with the workload fail-over? What configuration settings do I need to consider to optimize the workflow?

Nutanix collector fails to log into Prism central. This is the error I am getting. “Failed to login. Possible reasons could be having insufficient access permissions, missing binaries or failure to execute scripts” Has anyone seen this issue?

Hi there,We are currently deploying (and testing) Karbon as K8 orchestration platform for all our Nutanix platforms (worldwide). I have failed installation attempts from Prism Central.As a side note, we are using VPN Site2Site from centralised Prism Control and I can reach remote K8 VLAN from distant Nutanix deployment.

Hi,Is there any limitation on mixed hardware generation in one cluster Nutanix? Example old generation like G5 want to mixed with G8. Thanks

Hey everyone - we have 2 brand new nodes that need to be added to an existing cluster.  We enabled RDMA when we ran Foundation on that cluster and now need to add 2 additional nodes.  Do we run the script to choose which card to enable RDMA on before we add to the cluster?  Just looking for guidance on the correct way to ensure it is enabled on the new nodes as well. Thanks!

Hi, I just created a new account and wanted to activate the serial number for our NX-1065S-G5.I cannot activate because I’m not authorized for the account associated with the serial number.The mail-domain from our company changed and the old admins are not here any more.What to do?

I have 5 nodes equipped with 2*3.2TB NVMe SSD and 6* 1.92TB SATA SSD. of every one. all nodes are connected with 25Gb network. all nodes upgarde from AOS 5.15 to 5.20From the nutanix bible, in the scenarion with NVMe SSD + STATA SSD, the oplog will only reside in the NVMe SSD, and not in SATA SSD.So that is mean all the random write will first write in NVMe SSD and then drain to all the NVMe SSD+ SATA SSD?all the sequential write will pass OPlog and only writhe to extent store parally in all NVMe SSD + SATA SSD? How about the read I/O path? In some test, I found that when I do some I/O operation in VM, All the device (NVMe and SATA) have I/O counters and the IOPS are roughly the same in the prism-hardware--disk page. Seems the fast speed of NVMe SSD cannot be utilized.Does you have any suggestions to prove the fast performance improve by used NVMe in the nodes.I also checked that the disk status, as the folloing: It is used SPDK.

We have a Nutanix lab with 3 HPE PROLIANT DX360 GEN10 hosts. After we have done our tests, now we want to destroy everything and re-install everything again. What is the best way to proceed?

VStore refers to a separate mount point that is created with its own NFS namespace in a storage container. VStore Protection DomainThe namespace of a VStore is mapped to the protection domain when you protect the VStore. Such a protection domain is termed as VStore protection domain. A VStore protection domain allows you to protect the VStore. You can also unprotect the protected VStore. Files in a protected VStore are replicated to a remote site at a defined frequency. You can recover these files from the remote site in the event of a disaster. A Nearsync replication schedule of as little as 20 seconds to protect a VStore can be configured.

Hi there. I believe it was 5.18+ that the reverse proxy (apache) is no longer being used for cluster communication but something else. I can’t quite recall what it was called and where the logs can be found. Prior, I could access the httpd logs in the typical location for any http errors/faults but am not sure where to locate these now. 

I am new and watching all videos. I try to set up nutanix like proxmox CE with:3 x Dell R710 Hosts (nutanix installed on usb internal drive)1 x Dell R720 Freenas 20TB storage connected with direct Fiber With proxmox fiber channel setup was a nightmare, so can I use Fiber Channel here with Nutanix? My goal is if one of a host dies I have other VMs be ready | transferred into another host so like in VMWARE (pricy license). Let me know if I can achieve same with Nutanix and direct me towards hardware (Fiber Channel or 10GB ISCSI) whatever is easier and works well.There was a reply but I did not have a chance to reply.Can I use Nutanix for storage or I have to have 3rd party software like FreeNas?

Calm is integrated into Prism Central and does not require you to deploy any additional VMs. To start using Calm, you just have to enable Calm from Prism Central.  Please ensure, you have met the prerequisites to enable Calm. If the Prism web console is not registered from a Prism Central and the application blueprints have subnet, image or VMs on the Prism web console, the Calm functionality is impacted. Procedure:  Log on to Prism Central with your local ADMIN account. For detailed information on how to install and login to Prism Central, see the Prism Central Guide.

Good morning; not sure if this is the right place to ask. Have cloned the “Super Admin” role via the UI and this only transfers partial permissions. Following Nutanix KB article: 00006224, dated: 8th Apr 2020 … https://portal.nutanix.com/page/documents/kbs/details?targetId=kA00e000000LKhrCAGIt says we need to use REST API Explorer. I have extracted all the permissions from the default SA role, and created the JSON to ‘PUT’ these permissions into the cloned role but this is not working and I get a response code 422 and "'name' is a required property"Does anyone have some sample code that actually works that I can compare to?My code looks like this (example) {  "spec": {    "name": "<cloned role name here>",    "resources": {       "permission_reference_list": [
