Time Synchronization on Nutanix Cluster

Reliable and Accurate Time Sync is mandatory for distributed services to work in a reliable / efficient manner.Network Time Protocol (NTP) is used across different devices and services on a network to maintain reliability and integrity of services, data and other critical functions.Nutanix - AOS, built on web-scale engineering principles, distributes roles and responsibilities to all nodes within the system to form a large cluster of services working together. Accurate time sync becomes a vital requirement for all the different components to work reliably and help keep up system integrity.Accurate time sync, not just offers integrity and smooth operations but offers a lot of value even when things don’t work as they should. During troubleshooting of any service, timestamps are used to understand and co-relate root-cause, impact of the problem.In order for a distributed system such as Nutanix AOS to work smoothly - NTP is of critical importance. CVMs (Controller Virtual Machine) that co

How to change Controller VM and Host IP address?

Please consider the possibility of incorporating the existing IP scheme in the new infrastructure. If changing the IP address is the only option we can utilize a script to change the CVM IP address. You can use the external IP address reconfiguration script in the following scenarios: Change the IP addresses of the CVMs in the same subnet. Change the IP addresses of the CVMs to a new or different subnet.In this scenario, the external IP address reconfiguration script works successfully if the new subnet is configured with the required switches and the CVMs can communicate with each other in the new subnet. Change the IP addresses of the CVMs to a new or different subnet if you are moving the cluster to a new physical location.In this scenario, the external IP address reconfiguration script works successfully if the CVMs can still communicate with each other in the old subnet.  Following is the summary of steps that you must perform to change the IP addresses on a Nutanix cluster.

Quick tip: how to deploy a VM from an OVF to AHV

You have a nice OVF or an OVA image and you are ready to deploy that virtual appliance to AHV. There is just one more step required. Well, maybe more than one. It is not possible to import OVA and OVF files to AHV. Extraction of the files of the image as well as upload of the VMDK files is required prior to deployment.Please follow instructions provided in KB-3621 AHV: Import OVA and OVF image

Modifying passwords in Nutanix Environment

Security is the backbone of any infrastructure, so it is always recommended to set a strong industry-standard password for different components in your environment.Let’s say you want to implement a strong security password policy and have a need to modify the CVM and IPMI password in your environment but confused from where to start.Let us break the components for you: Modifying the CVM PasswordLogin in to the CVM.Change the admin password using the commandadmin@cvm$ passwd After you have successfully changed the password, the new password is synchronized across all Controller VMs in the cluster so you only need to follow the steps on just one CVM. Want to know more about the Nutanix password policy guidelines and steps for the above procedure Modify the CVM password. Modifying the IPMI passwordLogin to the IPMI Web Interface Click Configuration -> Users -> Administrative UserClick Modify and modify the password by entering the new password. What if you don’t have access to IPMI

Fresh Intall Nutanix Cluster - IPMI default password

Hello all,I’ve just finished the basic installation of a new 3 nodes Nutanix Cluster (NX-1065-G7 node). When i try to enter the IPMI password nothing happens. It seems the password is wrong. I have tried the default ADMIN/ADMIN password but it doesn’t worked (also admin/admin).Did the default password change with the release 5.15.x of AOS ?For information, the cluster has been created with the following parameters : AOS 5.15.2 Foundation VM 4.5.4.1 ESXi 6.7U3The “ipmitool user list” show me an “ADMIN” user with ID 2, so i think the account is correctly created. I ve tried on each of the 3 nodes and it’s still the same. So if the password set is ADMIN by default and is not working, can i safely change it with the ipmitool command ? Thx for your answers :)

Data services IP - ISCSI

If you ever need to present storage to your Guest OS directly via ISCSI here is some useful information for you. To provide access to cluster storage, Volumes utilizes an iSCSI data services IP address to clients for target discovery which simplifies external iSCSI configuration on clients. This iSCSI data services IP address acts as an iSCSI target discovery portal and initial connection point. Nutanix does not recommend configuring iSCSI client sessions to connect directly to Controller VM IP addresses. The data services address is owned by one Controller VM at a time. If the owner Controller VM becomes unavailable, the address moves to another Controller VM, ensuring that it is always available. This IP address is also used as a cluster-wide address by clients configured as part of Nutanix Files and other products. This IP address: Should be in the same subnet as the cluster Controller VM IP eth0 network interface addresses Helps load balance storage requests Enables path optimizati

Install VMware in Nutanix Nodes

We just purchased Nutanix ( 2 Appliances , 3 nodes on each ) , we are planning to use VMware Enterprise plus on them. I've few questions, I would be more than happy if I get the answers: 1- if we used VMware, all Nutanix functions will be applied ? ( for example, if one HD failed, the data will be transfered to another Hard disk? ) 2- If I'm using 3 nodes, and I'm utlizing all the CPU and Memory and HD capabilities for all three, once one node goes down, how the VMs on this node will go to the other nodes while we are utlizing their full capacity? 3- if one node fail, the VMware VMs on this Node will be Automatically moved to another Node ? 4- In general, is there any difference if we used Acropolies or VMware ? will we get the same functions on Nutanix?

What is the compatible version between ESXi and AOS

Hi Does anywhere can be find the ESXi version and AOS version interoperaability or compatibility? I found that in the foundation iso_whitelist file, there is some ESXi version has min_nos requirements. but differnet OEM partner has different requiremnts. But from VMware compability web site. ESXi is compatibility with most of the AOS version as the link. For example: ESXi 6.5 U3 --Dell has no min_nos requirements --Lenovo min_nos is 5.10.6 --Fujitsu has no min_nos requirements --HPE min_nos is 5.10.7 So if it is old enviroment, Does the ESXi version must meet the AOS version requirement in the whitelist?

System Date and Time, iDRAC Timezone and sync

Hi, I'm deploying a Nutanix cluster with three Dell nodes. The question rose about what timezone should be selected in the iDRAC. It was at first hard for me to undertsand how was the time set into the DRAC and the Bios, and I finally go this: Set Both NTP and Time zone In this method user will configure NTP and Time zone. In this case iDRAC will sync the time with NTP server and selected Time zone will be also applied. iDRAC will sync NTP server’s UTC/GMT time, so it is important that you configure correct time zone while configuring NTP on iDRAC. You can configure up to three NTP servers. It is always recommended to configure all three NTP servers for accuracy. We support IPv4, IPv6 and FQDN format for configuring NTP server address When NTP mode is enabled and iDRAC has received time through this interface, iDRAC will ignore any attempts to set iDRAC time through the server (BIOS, Open Manage, etc.) or CMC (for blade servers). Therefore, what I understand is that once the Ti

How to configure a web server for LCM Dark Site on a Windows Server

If your cluster has no direct access to the internet, you can use the Dark Site LCM bundle, which you can put on a local web server and use it as a source for the LCM downloads.The web server can be a virtual machine on the same Nutanix cluster that you want to upgrade or any other machine that the cluster will have access to. In this topic we will be creating a web server on a Windows machine and we will be using Microsoft IIS (Internet Information Services), so you will not need to download and install any third party software. Note that this guide is for absolute beginners, so you will not need any prior experience with this technology. So, first, we need to enable the IIS. Type the “Server Manager” in the Windows search and launch it.In the Server Manager click Manage in the top right corner and select “Add Roles and Features”. Click Next until you get to the Server Roles. In the list of Server Roles, select Web Server and click Next. The default options are sufficient. Click Next

Use of LACP for Nutanix Network Configuration

Hello folks, What are the advantages and disadvantages for use of LACP to improve east/west traffic and prevent unnecessary north/south traffic? Are there any documents on it's use for a Nutanix installation? Is the use of LACP very common for Nutanix installations? Are there folks kicking themselves for not implementing LACP. Thank you for your opinions.

Can external legacy storage be accessed via Nutanix AHV or ESXi?

There can be legitimate cases where access to external storage, such as massive tape libraries, massive disk archives is needed to some, but not all VMs running in a Nutanix cluster.  These VMs would be ideally under the AHV hypervisor, but is ESXi is an acceptable alternative.  These external storage systems would likely support 10GbE iSCSI (and faster) and/or 8 gbit fibre channel or faster. I understand that supporting such external access would make the VM “special” and would restrict VM mobility to other specific nodes that were configured for similar external access. The mobility issues are a later discussion, if external storage access is possible. If the external storage was a NAS device, running NFS and/or SMB, I believe it would be straigntforward … just define the external IP address in the VM, and access the data from the VM.  The same technique could be used for external iSCSI devices, for Ethernet iSCSi.   In many cases, if the external storage needed very high performance

Copy files to/from a containter

Should you need to access container’s content directly, upload files to or download files from a container on AHV there is a simple guide with few things to remember: Do not delete any data from the container via WinSCP or any similar tool. Appropriate Prism or CVM command line workflows should be leveraged for doing the cleanup if needed. Deleting VM disk files directly from Nutanix container may affect Acropolis service, which can result in inability to manage user VMs.How to upload VM disk files from your workstation to Nutanix containerUsing WinSCP, connect to a CVM using SFTP protocol and port 2222 using Prism element credentials. Enable the option to show hidden files by going to Options > Preferences > Panels and then selecting the “Show hidden files”  option under the common settings.

Configuring and Troubleshooting SNMP monitoring

We have already mentioned some helpful resources relevant to SNMP configuration. This time we will take a look at examples, logs location and connectivity testing. Important:Nutanix appliances support only SNMP v2c and v3 (support for v2c in AOS 5.5 and higher). Starting from AOS version 4.1, auth-type MD5 is no longer supported. With SNMP v2c Nutanix support SNMP TRAP instead of SNMP GETFollow trough to KB-1333 Configuring and Troubleshooting SNMP monitoring for commands and examples.The article also reference two more KB articles as well as SNMP related PowerShell commands:KB-2448 How to import MIB in zenossKB-2028 Integrating Nutanix with Solarwinds

CVM Non-Root Partitions Space Usage High - clear space safetly

Nutanix reserves space on the SSD-tier of each CVM for its infrastructure. These files and directories are located in the /home folder that you see when you log in to a CVM. The size of the /home folder is capped at 40 GB so that the majority of the space on SSD is available for user data.Due to the limited size of the /home partition, it is possible for it to run low on free space and trigger Prism Alerts, NCC Health Check failures or warnings, or Pre-Upgrade Check failures. These guardrails exist to prevent /home from becoming completely full, as this causes data processing services like Stargate to become unresponsive. Clusters with multiple CVMs having 100% full /home partition will often result in downtime for user VMs.The Scavenger service running on each CVM is responsible for the automated clean-up of old logs in /home and improvements to its scope were made in AOS 5.5.9, 5.10.1, and later releases. For customers running earlier AOS releases, or in special circumstances, it may
