Foundation

What is Foundation? Foundation is a Nutanix provided tool leveraged for bootstrapping, imaging and deployment of Nutanix clusters. The imaging process will install the desired version of the AOS software as well as the hypervisor of choice.   By default Nutanix nodes ship with AHV pre-installed (depending on your country), to leverage a different hypervisor type you must use foundation to re-image the nodes with the desired hypervisor. NOTE: Some OEMs will ship directly from the factory with the desired hypervisor.   The figure shows a high level view of the Foundation architecture:     To use a different hypervisor (ESXi or Hyper-V) on factory nodes or to use any hypervisor on bare metal nodes, the nodes must be imaged in the field. Foundation service is included on CVMs and can be accessed at port 8000 on a running CVM that is not in a cluster, or if the CVM IP address is not yet configured the Foundation Portable software can automatically discover the nodes.

IPMI Commands to Set Interfaces to Dedicated and Shared Mode

This article contains IPMI commands for checking and setting interfaces to dedicated or shared mode. For example, after a BMC upgrade, the IPMI might not be accessible. So, you need to verify and change the interfaces to dedicated or shared mode. Note: To run ipmitool commands on an ESXI host, prefix all commands with a forward slash (/). Note: To run ipmitool commands from a remote system such as the CVM (Controller VM), add the "-I lanplus", "-H <IPMI IP>", "-U <username>" and "-P <password>" parameters to the ipmitool command. For example: nutanix@cvm$ ipmitool -I lanplus –H x.x.x.x –U ADMIN –P <password> <command>     Quanta Platform Use these commands for an NX-3400 (Quanta) platform. All commands are executed dynamically and a restart is not required. Check the status. [root@host]# ipmitool raw 0x0c 0x02 0x01 0xff 0 0 An output similar to the following is displayed.1100           :00 - Shared port 1101           :01 - D

Re-IP - IPMI - how to change IP address

In certain instances, it may be necessary to change IP address of IPMI. This post explains how to achieve the outcome and where to look for help. Ther are three methods of configuring the IP address. In any case, there are only two simple steps: 1. Configure the IPMI IP addresses by using either the IPMI web interface or the hypervisor host command-line interface via one of the below: IPMI Web Interface Command Line (ipmitool - available on AHV and ESXi hypervisor hosts) BIOS For nodes from other hardware vendors, see the manufacturer instructions. 2. Log on to Controller VM on the same node in the cluster and restart Genesis service. For specific instructions, commands and examples see:NX Series Hardware Administration Guide: Changing an IPMI IP Address.KB-1486 [ESXi] How to re-configure IPMI using ipmitool - also includes instructions and examples on local user accounts management.

NGT Upgrade messages - what do they mean

Good morning All   I have a bit of an NGT issue, the Prism Central alerts me to say some VMs need a NGT upgrade, when I go to upgrade them I see the message “NGT can only be upgraded on 0/1 VMs which have the available upgrade of NGT”   Review and confirm buttons are greyed out so I cannot continue - what does the message mean and what do I do to get it to work?   Many thanks   Eric

DIMM number and slot installation order

Hi folks, Do you guys have ever think about the question. I read some guides and confused now. 1) node memory number: It seems every type of node has different supported memory number configuration: For NX-1064-G4, It shows only support 16x dimm ! What happens if I install any number， i.g 1, 2, 3,4,5,6 or any number [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/1450i89B4BCCDB3F2197B.png[/img] 2) node memory installed slot location: It also says there`s an fixed slot order for different number dimm scenario. what happens if I install dimm not according to the guide ? [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/1451iA5BA4F2ED2C9A97B.png[/img] 3) memory type: LR or R DIMM it also says there`s two type dimm, How to confirm which type is supported by specific type of node ? P.S my environment I have a node NX-1065-G4 with default 64g(4x16g installed in 1a,1b,1e,1f) and now I add two additional 16g dimm into slot 1g,1h. It work fine till now. but my me

How to configure a web server for LCM Dark Site on a Linux machine

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 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 Linux machine and we will be using Apache Web Server. Note that this guide is for absolute beginners, so you will not need any prior experience. For this example, I have selected CentOS 7 as Linux distribution. If you want to use another distribution, the commands can be slightly different, so you will have to consult the documentation of the selected distribution. However, if you use CentOS, you can simply follow this guide. So, to start, install the CentOS selecting the “minimal install” and log in as root. Also, you can select in the installer in the Software Selection the Basic Web Server option. Then, you can skip

OVS Networking - Unable to bridge eth0-4 for other networks - Error

What's my goal? Right. I have 3 networks that cannot talk to each other for "reasons". Mostly because we have a test system that utilizes the same IP addresses (ORACLE Reasons) and we test & demo software in Prod, Demo, & Test networks. I just did a foundation on my system because I did an upgrade and the networking customization I had to do with OVS changed and wouldn't work anymore. Now that I'm working on a new install, I'm having trouble configuring the network and getting issues I didn't have before. I've created and recreated several times using different varieties of below commands and still same outcome. Some commands below are from various tries, but same result.

Third-party backup snapshots are present in the cluster longer than the configured threshold.

Should you see message similar to “Third-party backup snapshots are present in the cluster longer than the configured threshold.” and wonder where it comes from keep on reading — you’re in for a treat!The NCC health check aged_third_party_backup_snapshot_check checks the cluster for dangling third-party backup snapshots that may be present for a protection domain. If a third-party backup snapshot has existed in the system for longer than the specified period, this check will raise an alert. These backup snapshots are snapshots that are generated from 3rd party backups (Veeam, Commvault, Rubrik, HYCU, etc.).The check passes if third-party backup snapshots are not present in the cluster longer than the configured threshold. The default threshold is 7 days, but this threshold value can be modified. The threshold can range from 1 day to 365 days.Administrators may specify how long a third-party snapshot is expected to be present in the cluster through Prism UI. This check is based on the b
