Deployment Success

Hi,I need an older version of Foundation and AOS. Where can I find them?I can only find the latest version to download.I need ,Nutanix Acropolis Operating System (AOS) 5.5.8Nutanix Foundation 4.3.2Nutanix AHV 20170830.185 Thank you.

Nutanix cluster works with the vDS and you can use the following guidelines and recommendations to configure the vmk and VM interfaces to be part of the vDS. Nutanix recommendations for implementation Keep the vSwitchNutanix, the vmkernel port (vmk-iscsi-pg), and the Nutanix Controller VM's virtual machine port group (svm-iscsi-pg) configuration intact. It should remain as a standard vSwitch and should not be migrated over to the vDS. Migrating the vSwitchNutanix to the vDS causes issues with upgrade, and also controller VM data path communication.

Hello, guys Please, help me with these two points: I’m searching for the spec int value that the sizer uses. For example, I see that a default processor is E5 2680v2, 42.31 specInt. But I searched on the website of Spec.org and I couldn’t find that and the other serverals values that use Nutanix sizer, as is shown in the picture. Maybe I search on the incorrect section of Spec.org, 2006? 2017? Please help.   I was wondering if the applied weight value is published in any website of Intel. I figured out that it is a fix value: 7.3 per processor for Xeon Gold 6244, for example. I wrote down the applied weights for 3,4,5 and 6-node configuration (dual-processor) and the calculations works this way: Applied wieight in 3-node cluster: 43.8 (7.3x6) Applied wieight in 4-node cl

The Nutanix cluster in Vcenter must be configured according to Nutanix best practices.    A quick checklist for the recommended settings review is as follows:   vSphere HA Settings   Enable host monitoring   Enable admission control and use the percentage-based policy with a value based on the number of nodes in the cluster.  

Hi, I'd like to change Cluster External IP Address but CVM IP Address is NOT change. Do I have to stop the cluster ?  or Do I change that online? Regards,

Hi everyone, I’m trying to clone a vm with a cloud-init customization but i don’t know how to put the cloud-init in the userdata string. Thanks for you help

Disk structure of a CVMThe CVM is the core of the AOS clusters, but have ever wondered how disk layout exists within them?I provide a brief overview of its structure in the following post.The main thing that most of you are familiar with already, is that the LSI controller is passed directly to the CVM in order for it to have direct access to the disks in the node. When combining all the disks space from all the CVMs within the cluster it provides the unified software define storage pool used to store your data.That’s why when you run “df -h” in the CVMs you will see the data disks mounted in the following mount point:

Acropolis Operating System upgrades happen across the cluster, one CVM at a time. Here is the next installation of the Upgrade Series as promised to provide you quick tips and tricks to plan and execute your upgrade activities with ease.   In simple words, AOS is the Operating System running on the Controller VMs(CVM) in the cluster and is critical in handling the data I/O from the user VMs in the cluster. AOS can be called the core of Nutanix Hyper-converged infrastructure.   As reference documents, you can check the below Guides: AOS Advanced Administration Guide

You must be familiar with some of the techniques you can use to migrate VM’s onto AHV from other hypervisors. These include our popular Move solution, if you wished to move away from ESXi or Hyper-V. Another way is to add the VM’s into a Protection Domain and migrate the PD itself. Of course, this is only compatible with Nutanix clusters being the source and destination cluster.   As much as we would not want you to, there could arise situations where you may need to transfer VM(s) back to a different hypervisor. Currently, Move does not apply

Dear Sir/ Madam, I am working on a further Nutanix project and I have installed 8 x NX8155 servers. Each server has 6 x 10g TwinX cables and 2 x CAT6 copper connections. I am again trying to find any suitable cable manager due to the amount of physical cabling for each device. Can someone please advise if there are any cable managers that Nutanix is aware of or via a third party as I am struggling to locate any. Thanks in advance. Simon.

Looking for get-ntnxvm -SearchAttributeList syntax. Since the get-help doesn’t provide any information besides:  “Search attribute list, only searches on few attributes. For accurate search, provide field names” Can someone provide an example of how to use this parameter? Most examples seem to use -searchstring.  I would like to search for vmname.  I know I can use a where clause and filter that way but curious if -SearchAttributeList could also do it.

Hi all, the import SSL certificate form allows me to choose between key’s format. I have RSA2048, ECDSA384 along with other ECDSAs.   I am pretty sure I sumbitted a ECDSA384 key with secp384r1 curve. I can safely paste my key here because it’s now revoked: -----BEGIN EC PRIVATE KEY----- MIGkAgEBBDAzjnBwsncbnlR643ngw7M8/urUzuSVNNGjB84kTxgCyplXsbSuKzyl gxiijfhY3vOgBwYFK4EEACKhZANiAAS5DDtPOWrgYA/XKxzNEM1E3TER7Ol70njH JsQC+WU8lMH4d0s9G9MfIzQ1qHB7PukydkpdwMV2MYpaKpmQyrNO75zeRr/Jle/M 76vLL7FbZP9lzvwVTnJVXttXhBctM0o= -----END EC PRIVATE KEY-----   Please can anyone explain me what’s wrong? Thank you so much! francescm

  I did a node remove operation, but it seems to be completed in the task, but there is no log. Can I know where the task log is recorded in cvm?

Is there a document that guides on how to use Move migration via command line interface?  I know that there is a web GUI tool.  But, I am wondering if there is another way thru CLI.

Hi folks, I have done a successfull VM migration using Nutanix Move 3.5.2 from ESXI 6.5 to AHV 20191030.415. All migration process is validated and fine, the VM can be migrated from ESXI to AHV but it failed when I try to boot in from AHV console as this picture :   

We often ask ourselves, what do these various Upgrades entail and what actually happens during an upgrade. Here is a high-level description of what happens during the various Nutanix core software upgrade processes. I have assumed it is a minimum 3-node cluster and you have already determined the Upgrade version.  Note for all the Upgrade below, it is important to perform health checks before upgrading any component (check KB 2852).   1.

AHV uses Open vSwitch (OVS) to connect the CVM, the hypervisor, and guest VMs to each other and to the physical network.    Open vSwitch: OVS is an open source software switch implemented in the Linux kernel and designed to work in a multiserver virtualization environment. By default, OVS behaves like a layer-2 learning switch that maintains a MAC address table

All services are Up and running. Other CVMs can ping PCVM. Firefox browser loads with Error Message "Secure Connection Failed" and the Code "PR_END_OF_FILE_ERROR".     Solution Try one of the 2 methods to resolve this: 1)Try to make new profile via `about:profiles` and set it to default. If it is working, export your bookmarks from the old profile and import them to the new profile. 2) Simply restart the existing profile.       Solution reference from community Mozilla support:https://support.mozilla.org/en-US/questions/1267074

Acropolis Dynamic Scheduling (ADS) is responsible to examine the load on various components for hotspots and calculate what migrations can be done to balance the load without causing additional hotspots. Lazan is the dynamic scheduling service for AHV.   Lazan monitors the following resources:   Total CPU usage of each of the guest VMs. Storage controller (stargate) CPU usage per VM or iSCSI target.   Lazan does NOT monitor the following:   Memory. Apart from ensuring its migr

if the ipmi vlan option is disabled and i configured the switch side ports to a specific vlan, Will i be able to reach the ipmi if i connect my workstation to an interface in the switch with same vlan or do i need to enable the vlan option in nutanix and put the vlan tag as well.?

Hello I have a cluster with 3 nodes and AOS 5.10.10 and need upgrade to 5.15 but the nodes not have access to Internet. I upload the AOS 5.15 and show me in the Prism Console the versionm but not permit run the upgrade to new version. Need to know if is possible run the upgrade directly through cli to update the cluster. Thanks for your comments

Did you know you can secure your IMPI Web Interface with an SSL Certificate?   Securing the IPMI Web interface is recommended to help reduce susceptibility to attacks. You can further enhance security by installing your own customized certificate or a CA-signed certificate. Nutanix recommends strong keys and signature algorithms. The IPMI module supports SHA2 and RSA 2048 bit SSL. Avoid long certificate chains or large certificates. If the IPMI module shows the default or previously-installed certificate after you install a new one, or you are unable to log in to the IPMI web interface, the chain is too long (chain length longer than one) or certificate too large. As a test, create a simple self-signed certificate and install it to ensure the IPMI is working correctly before attempting to install larger certificates.  You can use openssl or keytool to generate keys, certificates, and signing requests.
