Cluster Creation

Cluster creation or initialization is a process of bootstrapping the cluster by configuring the unconfigured nodes,  load some node information into Zeus configuration file and start the services.  Let's break it down.  What is an Unconfigured node? Node which are factory shipped. Node which was removed from an existing cluster. These nodes are typically Pre-installed with CVM/HypervisorNO IPv4 address is configured But IPv6 link local address configured on eth0. This will always remain on a host. Before you begin to create a cluster with your brand-new nodes,You Must Have  IPv4 Address configuration IPMI IP address Hypervisor IP address CVM IP address DNS/NTP IP address (Required while creating cluster via foundation) Hypervisor and CVM should be installed.   What are the methods of Cluster initialization? Foundation:  One click process for  cluster creation Re-Images multiple nodes  Assigns IP address on each node Manual Manual Hypervisor inst

Using LLDP protocol for details about connected switches

In Nutanix clusters running AHV hypervisors, we can use the LLDP protocol to find more details about the directly connected switches. LLDP needs to be enabled in the switches for the details to be seen in the AHV hosts. From the AHV host,  [root@AHV-HOST ~]# lldpctl------------------------------------------------------------------------LLDP neighbors:------------------------------------------------------------------------Interface: eth2, via: LLDP, RID: 7478, Time: 35 days, 22:55:59 Chassis: ChassisID: mac 00:XX:XX:2d:b6:ba SysName: AHV-HOST SysDescr: Network Switch TTL: 120 MgmtIP: xx.xx.xx.xx Capability: Bridge, on Capability: Router, off Port: PortID: ifname Ethernet9 PortDescr: Nutanix-AHV-Node-A MFS: 9236 VLAN: 100, pvid: yes------------------------------------------------------------------------ You can get the following switch details: Management IP address MAC address I

Recommended switch port buffer size

Is there a minimum or recommended switch port buffer size? I plan on using eth0 and eth 1 to be connected to two different 10G switches but was wondering if there is a minimum buffer size or switch port requirement?

NX-8235-G7 Switch Port Configuration

Good Morning:We are in the process of deploying new NX-8235-G7 nodes that are connected to a pair of Cisco Nexus switch. Everything seems to be working well, with the exception of the switch occasionally receiving RX Pause frames from the servers. While this may not necessarily be a problem, I am doing my due dilligence.The switch ports the nodes are connected to are configured as follows:Connected as active/standby NICs Connected via 1 meter 10GE DAC cables 802.1Q trunk Speed/duplex auto-negotiation Flow control auto-negotiationThe nodes themselves are configured with the default network configuration that comes from the factory with the exception of anything that is necessary to support the use of ESXi and our network environment.Any suggestions or validations of how the switch ports should be configured? Thanks!

Repair Host Boot Disk: Failed to apply IPv4 address to phoenix mode

Has anyone ever attempted a Host book disk repair and encountered this issue before?     All cables and SFPs are plugged in as if it were still in production. Have not yet attempted to rebuild via foundation as these were the steps provided by Nutanix support:  https://portal.nutanix.com/page/documents/details?targetId=Hypervisor-Boot-Drive-Replacement-Platform-v510-Multinode-G3G4G5:Hypervisor-Boot-Drive-Replacement-Platform-v510-Multinode-G3G4G5   Steps Taken: Downloaded and burnt phoenix.iso to USB Booted USB into Phoenix Kicked off Repair Host boot Disk and uploaded whitelisted ESXi image Encountered error I have a case open with support and have escalated and figured that while i’m waiting I could ask the community. Will provide a response here once we figure out the issue. Cheers All!   (Edit: I posted this in the CE forum by accident)

Nutanix Installation with different network ports speed

Hello Everybody,Hope you’re all doing well !I want to install Nutanix using Foundation.I have 3 Lenovo nodes and one Cisco 2960X switch that consists of 24 x 1 Gig RJ45 ports and 04 x 1 Gig SFP ports.Unlike Supermicro nodes, Lenovo nodes do not have Shared IPMI ports.So, for each Lenovo node, I have to connect 01 x 10 Gig port and 01 GbE IPMI Port to the same CISCO 2960X switch (10 Gig ports of the nodes connected to 1 Gig SFP ports of the switch and 1Gig IPMI ports to the 1 Gig RJ45 ports ).Please take a look of the picture below…Since 10 Gig ports of the nodes are connected to 1Gig ports of the switch, I wonder if this architecture can allow me to install nutanix and create the cluster without any issues ? Thanks in advance.

Prism Network view anomaly?

Hi All I have something odd in my Network view in Prism - I have 3 switches ( 1 switch is a 2 switch stack) but the view shows 5 switches, 2 classified as None. The None entries have the ip addresses of one of the single recognised switches and the stack which is already identified. The other odd thing is that the Nones have ports that I would expect to see in the identified switches. Can anyone tell me how to correct this?

Two clusters sharing the same subnet for network segmentation ?

Hello, I’m trying to configure two AHV clusters (3 nodes) for replication. Both environments are running AOS 5.11.2 on HPE DX360 Gen10.   The network environment is spread between two stacks: one stack dedicated to the storage with 10Gb interfaces and one stack for the LAN with 1Gb interfaces. There is no connection between these two networks. After the deployment of the nodes and the configuration of the clusters, I start to configure the Backplane Network with the following parameter: Subnet: 172.16.250.0 Netmask: 255.255.255.0 VLAN: 202 Host node: br1 The backplane network of the first cluster works without any problem. When I do the same (with the same) for the second cluster, it fails. It says that the IPs addresses are already in use.  I would like to specify a VLAN/subnet where both clusters have their backplane IPs so I can use the backplane network for the replication between both clusters.   I hope this is clear.   Kind regards,   Fred

IPMI network configuration

Let say that you have updated your IPMI IP address or moved it to another subnet, after you finish the update you are not able to log back in to the IPMI. This happens as a result of not restarting the genesis service on the local node which people tend to forget, after you make the change you must restart the services on the same node’s CVM by running “genesis restart”. If the restart is successful, output similar to the following is displayed: Stopping Genesis pids [1933, 30217, 30218, 30219, 30241] Genesis started on pids [30378, 30379, 30380, 30381, 30403]   You can change the network configuration of your IPMI using one of the following methods: Configuring the Remote Console IP Address (IPMI Web Interface) Configuring the Remote Console IP Address (Command Line) Configuring the Remote Console IP Address (BIOS) For the full documentation check out this page.

Network Visualization with Cisco Nexus 9K Switches

Hello ... can anyone provide feedback on getting Network Visualization working with Cisco Nexus 9K Switches. The Nexus Series is on the Supported Switch list, but I've had a ticket open with Support for weeks and we can't get it working. [url=https://portal.nutanix.com/#/page/docs/details?targetId=Web-Console-Guide-Prism-v510:wc-network-visualizer-supported-switches-r.html]https://portal.nutanix.com/#/page/docs/details?targetId=Web-Console-Guide-Prism-v510:wc-network-visualizer-supported-switches-r.html[/url] LLDP is enabled globally on the 9K, and I can populate the 9K switch info into Prism just fine. The issue is I can't get any port data. Nutanix Support is saying the issue is by default the "port-id-subtype" is set "locally-assigned", and it needs to be changed to "interface-name". The 9Ks are in ACI-Mode, not NX-OS, and no one seems to know how or where the change is made. Has anyone gotten this setup to work? Here are some pics from my environment. Thanks! [img]https://d1

Hello, I'm not sure if this is the best place to ask this, but I'm not sure where else to ask. I keep getting a message that there's an NGT Update Available on just one of our servers running Ubuntu. I ran an update and it went from 1.1.2 to 1.5.2. After resolving/acknowledging the issue it reported the same message again the next day. Is 1.5.2 not the latest?

Antivirus on Nutanix AHV hosts and on CVMs

If you are trying to install any third party software, specially Antivirus packages on Nutanix AHV hosts or Nutanix CVMs please consider the following: As for running antivirus (or any third-party software) on the CVMs and AHV hosts, this is not something that we support or can allow. The CVM should be treated as a network appliance, with access controls put in place to ensure that only authorized access is allowed, and kept up-to-date with the latest CVE patches. Installing any packages on the Nutanix CVMs is unsupported. Moreover, installing packages on the CVMs will void the support. In general, an antivirus being installed on the Nutanix CVM is not recommended as it can have ill effects on performance and cause negative impact on the stability of the system. However you can install antivirus on HYPER-V and VMware hosts, just follow these articles: KB 2360 Antivirus on Nutanix on vmware. KB 5153  Antivirus on Nutanix Hyper-V Nodes.

Portable Foundation - Windows 10

Sorry if this topic has already been covered. I have been trying to use the new "Portable Foundation" app that runs on windows to image a cluster without using a VM. Every time I try (three so far) I get errors that the IPs I have provided are already used. I am using a flat switch and the 10G and 1G are unplugged from the customers switches. I have tried with my laptop in and out of airplane mode, with the firewall on and off and still receive the errors. The only difference is that each time I try, the listed IP conflicts are never the same. It will tell me in the first try that x, y, and z are in use, then the second time it may say that a, b, and y are in use. Any ideas? I really like the idea of this app working. Thanks, -David [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/d0b2826a-077a-429a-84fe-be3b71f35256.png[/img]

Clear critical alerts with a later date

Hi,I had a problem with the NTP server configured on the Nutanix cluster, unintentionally changed the date to 09012020 instead of 01092020,  the point is that after solving that problem, now the cluster reports to me Critical alerts dated September 1, 2020. The date of the NTP is already corrected, but Web Console  shows some critical alerts, but those alerts are not shown with ncli, but  are shown with Alert tool. I have try to aknowledge and  resolved them, but they are NOT eliminated from alert_list.Does anyone know what I can do so that the web console no longer shows them?

Setting up cluster with no DNS and no NTP ?

Hi, I'm implementing Nutanix AHV at a customer in a bunker environment. There is no internet access, and the infrastructure will have minimal to no LAN communication outside of the cluster infrastructure. The customer expected to use IP and shot names based on hosts files instead of DNS resolution. Unfortunately, on Foundation, there is no way to setup the cluster with no DNS. And I guess NTP will be the same, but I didn't get there. Any workaround ? Or are NTP and DNS mandatory for the cluster to work ?
