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.

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

While we the topic of VirtIO drivers has already been touched in Sarab’s post on Installing Windows VM and VirtIO drivers, we would like to bring two more KBs to your attention.One is on AHV | How to install VirtIO drivers for Microsoft Windows Server 2008 (KB-5666) and the other one is AHV | Nutanix VirtIO drivers for Windows Server 2019 (KB-6495).N.B! Nutanix does not release or maintain VirtIO drivers for Microsoft Windows Server 2008. However, you can still use stable VirtIO drivers available from Fedora project website.Nutanix recommends to use the Stable VirtIO-Win drivers.

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

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

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 ?

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.

IPMI - Cold reset, Partial reset and Factory Default

There could be many reasons why an administrator would want to perform a factory reset of the IPMI/BMC module. Whatever the reason maybe, knowing the different options and its differences is important.Using ipmitool, we can perform 3 types of resets each with its own implication. Reset BMC Partial factory reset (IPMI and BMC reset but will preserve Network settings) Full factory Default reset (Potential to lose IPMI network settings)Before you execute any of these commands, note the IP_Addr, Net mask and GW IP_Addr for the IPMI. ipmitool lan printUsage note: On VMware ESXi hypervisor, place a leading "/" in front of "ipmitool", for example, "/ipmitool". The executable is located at the top-level root directory.Check out the KB-8123 for detailed instructions.

IMPI password recovery: AHV, ESXi and no hypervisor (+bonus)

Companies merge, hosts are inherited and repurposed, administrators come and go and not necessarily leave things in order after themselves. Or what if you forgot the password and the record of it is not recoverable? Where there’s a will, there’s a way. I touched the other day on how ipmitool can be accessed from a CVM CLI but would require authentication details to pass on to the IPMI. Well, the host or rather the hypervisor installed on the host does not have to do so. Hence even when ADMIN account password (or any other account with full privileges) is lost the IPMI is still accessible from the hypervisor CLI and you can still reset the password, set up new user entirely, or set a new password for a user. The process consists of several steps: Log in to the hypervisor on the host (AHV or ESXi). List user records using ipmitool. Take note of the user ID. Set the password for the user ID. The task is complete. Conveniently, commands syntax between AHV and ESXi differs only in the
