Looking at the site below, I understand that ESXi 7.0 is supported. But I'm not sure if vCenter 7.0 is supported.https://portal.nutanix.com/page/documents/compatibility-matrixIs it a problem to use vCenter 7.0 ?Also, where can I find out which vCenter versions are supported?
Nutanix AHV uses Open vSwitch(OVS) to connect to the CVM, the hypervisor and the user VMs to each other and to the physical network on each node. The CVM manages the OVS inside the AHV host. Since the OVS is an open source software switch that behaves like a layer-2 learning switch, it maintains a MAC address table. Each AHV server maintains an OVS instance, managed as a single logical switch through Prism. Bonds:When multiple uplinks are used they are added to a bond acting as a single logical interface, to which the bridge is connected. Open vSwitch (OVS) does not support bonds with single uplink and as workaround we directly connect bridge to single uplink.WARNING:Avoid the use of a single uplink configuration and do not attempt to modify a single uplink configuration using manage_ovs if the version of AOS is 5.10.x prior to 5.10.4. Warning:Updating uplinks can cause short network disconnect. It is strongly recommended performing network changes on a single node at the time after ma
I am trying to install ubuntu server 20.04 LTS but everytime I reach the point where to set the profile (name, username and password etc...), I get an error “Sorry, there was a problem completing the installation”…I have downloaded the ISO file from Ubuntu, and my VM settings are:CPU = 1Core or. CPU = 2Memory = 4Cd-rom = ide.0Disk = scsi.0 and 100 GiB Please advice how I can fix this, and install my Ubuntu server 20.04 LTS
HelloThank you always for your help.I'd like to update the Nutanix firmware and bios.I'm trying to use LCM.Finish configuring the LCM Darksite Web server.The update list does not appear after LCM registration. We used the latest dark site LCM and nx firmware bundle provided by Nutanix. lcm_dark_site_bundle_18.104.22.168.21375.tar.gzlcm_darksite_firmware_nx_1.6.0.tar What's the problem?
Hi all,Running AOS 5.10.5, i have changed my cluster from RF2 to RF3, including my main container and the “SelfServiceContainer”,however a week after the change I’m still seeing this error regarding extent groups,I believe that this is due to NutanixManagementShare still being RF2 (with no ability to change it, since its a systemmanaged container), or is there some other reason?
Many users are unaware that there are additional (beyond what is displayed through the Prism web user-interface) configurable security-related options which can be used to increase the security settings of the controller VMs (CVMs) themselves. These options are modified using the Nutanix Command Line Interface (nCLI) of the CVMs and include some of the following items: Enablement of an Advanced Intrusion Detection Environment (AIDE) Enforcement of a strong password policy Enablement of a defense knowledge consent banner Restriction to allow only SNMP version 3 You can find more information regarding these options, including the procedures to enable/disable them, within the Hardening Controller VM section of the AOS Security Guide. Also to note, there are similar options available for Acropolis Hypervisor (AHV) hosts which are configured using the same procedures. You can find more information regarding those options within the Hardening AHV section of this same guide.
Hi there!I’ve installed NutanixCE (twice!) on my existing hardware (custom SuperMicro servers, not Nutanix hardware, though they meet the required specs). We found it useful, and decided to spring for Ultimate Licenses for the non-Community Edition.So I’ve got those licenses, but now I’m having a heck of a time figuring out what to download and install! For CE, there was a nice procedure to create an install image on a thumb drive, but I’m not seeing the same thing for non-CE.Can anyone point me to documentation that spells out what needs to be downloaded and how to install it?I’ve already found the AHV admin guide, but that doesn't have installation instructions.I’ve found the “Field Installation Guide - Foundation 4.5.x”, but the “https://portal.nutanix.com/#/page/docs/details?targetId=Field-Installation-Guide-v4_5:Prepare%20Bare-Metal%20Nodes%20for%20Imaging” section seems impossibly complicated; do I really need to install and configure a VM on virtual box on a laptop in order to
Hi all!I’m looking for a HCL that details the exact firmware versions of specific components of a server to make sure that we are in the clear before we install or upgrade Nutanix.As far as I can tell there isn’t anyone to be found, at least not for someone who doesn’t have an account for the support portal (and I find it pretty odd to “hide” the HCL).I know there are HCL’s to be found outside of the support portal but those are extremely generic.Is there an HCL that is this detailed or is it only through trial and error we can figure out if we have the correct firmware?Thanks.
We have a couple of 2 node cluster with a Witness VM on a separate host but I can not seem to find any documentation on how to enable SNMP on it.Using the “ncli snmp add-user” command that works for normal CVM’s just throw me the error:“Error: Cannot connect to Prism Gateway”Any ideas?
https://next.nutanix.com/how-it-works-22/network-segmentation-basics-38414It seems the network segmentation 2.1 doesn’t support the isolation physically between the backplane and management. So, it tries to isolate logically following this procedure.ISOLATING THE BACKPLANE TRAFFIC LOGICALLY ON AN EXISTING CLUSTER (VLAN-BASED SEGMENTATION ONLY)https://portal.nutanix.com/page/documents/details?targetId=Nutanix-Security-Guide-v5_15:wc-network-segment-on-existing-cluster-wc-t.htmlAOS5.15.1 / ESXi 6.7u3 Standard vSwitch, vSwitch0 Port Gourp: Backplane Network, CVM Backplane Network (for CVM)it doesn’t recognize any port groups.The procedure doesn’t mention about the vSwitch0 or port group condition. Is there any information of this?Thx,
Are there plans to validate a version of VMware’s ESXi hypervisor that addresses recent vulnerabilities outlined here; https://www.vmware.com/security/advisories/VMSA-2020-0023.html The proposed version to address this threat is ESXi670-202010401-SG for existing 6.5 hosts or ESXi675-202010401-SG for existing 6.7 hosts. It appears that the latest json version for download from My Nutanix is 6.7.0 U3 - which is slightly older than the version being proposed to resolve the vulnerability. Thanks!
With AHV-20190916.189, Nutanix supports Directly Attached Volume Groups in a Guest VM Cluster. On AHV clusters, you can create a guest VM cluster by directly attaching a volume group to guest VMs.After you attach a volume group to guest VMs, vDisks appear as SCSI devices to the guest operating system and you do not need to set up any in-guest connections when you are creating a guest cluster. If you directly attach volume groups to guest VMs, you can seamlessly share vDisks across VMs in the guest cluster.You can directly attach a volume group to guest VMs to create the following guest clusters:1. Microsoft Failover Cluster (MSFT)2. Red Hat Enterprise Linux (RHEL) Cluster For more details, refer to following:Guest VM Cluster Configuration (AHV Only)Create Guest VM Clusters by using iSCSIAcropolis Release Notes
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
Hello Team,Is it possible to transform a full-flash cluster to an hybrid one without losing data? (third party platform).Licenses should not be upgraded because SSD space would not change but the necessary SAS disks would be added to add extra cold data space
As companies become more security aware, third party security tools are being utilized more heavily than ever before. One such tool is a security scanner which can review open network ports within an environment and report back on certain vulnerabilities (CVEs). This includes the open ports of Nutanix specific components such as the IPMI.While it is important to keep the IPMI/BMC upgraded to the latest version so as to integrate the latest security patches, there are CVEs that will still report as failed by scanners based upon the default IPMI configuration. This is due to the virtual media port (623) and the iKVM port (5900) being opened by default.The virtual media port allows the user to open a remote session to the host console and the iKVM port allows the hosts to query information from the BMC.The specific CVEs affected by these two ports being open can be found in KB 2555. NOTE: If these features are disabled, you will be unable to query any BMC info nor able to open a remote co
Hi there. I’m trying to plan an upgrade on our nutanix clusters from VMWare 6.5 to either 6.7 or 7.0 and I’m having a bit of a struggle figuring out the compatibility of the different VMWare versions along with our Nutanix clusters. We have two Nutanix clusters, our main site is a 7-node cluster with 5 Gen5 nodes and 2 Gen7 nodes. Our remote data center is a 6 node cluster with all Gen 6 hardware.Our main site is running AOS 5.10.5 LTS and our remote datacenter was just recently upgraded to 5.15.2 LTS in preparation for the vmware upgrade. I plan on upgrading our main site to the same AOS version of 5.15.2 LTS.Where I have an issue is that when running the VMWare Assessment Tool (VSAT) I keep seeing notifications on each cluster that certain nodes may not be compatible with VMWare 6.7 or 7.0 because of various devices that “May not be supported” yet say things like “is certified but current driver (ixgbe) is not supported”. In some cases the same exact nodes in the same cluster wit
I see that ERA 2.0 has a prerequisite of SQL Server SQLPS PowerShell module. Does anyone know what specific version is required? I ask because when trying to register a single node, I receive the following error:Operation Failed : Unable to import SQLPS module. Please make sure that SQLPS module is available to proceed with Dbserver VM registration.I suspect that the version of SQLPS PowerShell module that we have installed on our SQL servers is too new.
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.
We have a 15 block HPE environment built with AOS 5.15.2. we need to enable flash mode on a NVMe device (vmdk) which is presented within vSphere but cannot be seen via prism element under the VM vDisks or via ssh shell to cvm’s is this feature not currently supported? any ideas I am struggling to find much on the support portal?still unsure on this how do we pin the NVMe vmdk to the performance tier cheers
Hi, I just installed a nested CE 5.18 2020.9.16, and it is OK. single node. vmware esxi 6.7 The host IP is pingable, but the CVM IP is unpingable from outside pc.so cannot open web consoleWhen i login the host, can ping the cvm ip. how to fix the issue? thank you so much.
Hello,i have some questions regarding “Switch stacking”1-) Is it possible to use " 2 stacked switches " as TOR with AHV? there will be a problem if we use this configuration?2-) The best practice is to use 2 Stacked switches or 2 individual switches?We plan to use Active-Backup configuration and conect SFP to Switch1 and the other SFP to Switch2I am not a network specialist so i am not sure if both switches are stacked, and we plug 1 SFP to SW1 and the other SFP to SW2, the active passive configuration will work
