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?
Hello, I`m not new to nutanix, but have a long time not focusing on nutanix installation step. while I installed nutanix with foundation+Phonex(NOS location selection)+Hypervisor image one year ago, I think Phonix is just exactly NOS at that time. I find it seems to have new method to image node: Foundation+AOS(NOS location selection)+Hypervisor image, or even having an JAVA applete+Foundation+AOS(NOS location selection)+Hypervisor image I`d like to confirm detailed difference between NOS , AOS, and Phoenix. I have asked guys, no one can explain this clearly to me. also what make me confused is there are varous statement about it in different guide(it is self-contradictory) , also Which phonex package should I use ? shows you need manually make/generate phonix ISO with AOS , but sees you shoud use the Phonix ISO downloaded from nutanix portal site ! look at these slices : "Phoenix is a tool used to install the Nutanix Controller VM and provision a hypervisor on a new or rep
Hi guys..Is it possible to customize/deploy an already created sysprepped image in nutanix via the script engine?Its not that well explained in the kb.. Or i have not found the correct kb.I want to deploy patched images based on a XML unattendede file if possible.I really like the VMware customization options.
I have 8 port 10BaseT 10g switch and I have four nodes with dual 10g and dual 1g. I also have a 1g switch with 50 ports. If I plug all 8 10g nic into the 10g switch I will not have an uplink port. However I still have thx 8 1g nic. So this leaves me with a couple options, and I was curios what best practice would be. A few options I have consider are: [list=1] [*]Only use one of the two 10g ports per node. [*]Configure AHV to use 10g for I/O only and 1g for connecting to the outside world. *not sure if this even doable* [/list]
When there is a new patch released by VMware for ESXi, you may want to check the Compatibility Matrix on the Portal, but the matrix shows only ESXi versions and update numbers, it doesn’t show every patch build number. What to do and how to understand if the patch is supported or not? Let’s break down the ESXi versions into possible options: Versions. Those are the numbered versions, for example, 6.0, 6.5, 6.7 and 7.0. All the versions need to be qualified and the qualification is a requirement. They will not be supported if they are not qualified. Check the compatibility matrix on the Nutanix portal to see if it is supported. Updates. Those are what you usually see after the “U” in the version name, for example, 6.7U1, 6.7U2. 6.7U3. They also will not be supported until they are qualified. Check the compatibility matrix on the Nutanix portal to see if the Update is supported. Patches. There are many ways that VMware calls its patches, examples are: ESXi 6.7 EP 15, ESXi 6.7 P01, ES
Hi all, I read the acropolis administration guide and the Acropolis hypervisor Best Practices guide. thanks lot i would it and i have it. It's explain how to create bridge, bond, separe 10Gb interface and 1G interface. But nothing for create a network vlan (tagin or native) on the NEW bridge. If you try by the GUI like this [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/722i398F93F01768FE81.png[/img] The network will be created in the native Bridge (BR0) so if we are in this situtation : (best practice 22.214.171.124) [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/723i317753D8C4A0B474.png[/img] the commands are : nutanix@CVM$ allssh "ssh email@example.com "ovs-vsctl add-br br1" " nutanix@CVM$ allssh "manage_ovs --bridge_name br0 --bond_name bond0 --interfaces 10g update_uplinks" nutanix@CVM$ allssh "manage_ovs --bridge_name br1 --bond_name bond1 --interfaces 1g update_uplinks" and for create the Network : ac
Hi team, i have questions about capacity calculator let say i have config for 3 node like the picture below, so in prism will show me 17TB logical capacity correct? and i have concern in extent store RF2 and N+1 (11TB) in sizer tool, what happen if i have data 15TB which is bigger than RF2 and N+1 size (11TB)?
A piece of good news to begin with: it is possible to perform a non-disruptive memory upgrade on one node at a time.Start with a little bit of prep work. Check cluster status. Download and install the latest version of NCC (Nutanix Cluster Checker) and execute all health checks. Resolve any issue found. Identify the node you are performing the hardware maintenance on by turning on the chassis identifier lights on the front and back of the node that you will remove using one of the following options. The lights turn on for four minutes unless you change the value. Now you can migrate VMs of the node. Shut down CVM and the host. Replace or add DIMMs.For detailed outline of the process please refer to KB-1623 HW: Upgrading Physical Memory
Hi Everybody, I'm new to Nutanix, I'm having my first node installed on Monday so ery excited ! I have the chance to dedicate a Nutanix host for a Lab and will have the time to play around with it. I've seen that 192.168.5.0/24 is a dedicated subnet for the CVM, but this is also the subnet in which my Lab resides. Is it ok to use the CVM and the production VM in the same subnet ? What are the options ? I've been told the CVM network cannot be changed. But is it ok to have the VMs and the IPMI in the same LAN ? For a production environment I can understand that security wise and performance wise, this is mandatory to split the subnets but in my case this is a bit different. Thanks. Cheers. Fred.
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.
We are planning to connect 2 stacked Catalyst 9300 to a Nutanix Cluster. While doing research I found a document recommending the Nexus 9300 and specifying that the Catalyst 9300 wouldn't meet requirements for the Data Center. There was no reasoning for this and I would like to know why the Catalyst 9300 switches are not recommended. Thanks in advance, Ingrid
Hi Team, i am new to Nuatnix and i have requested to setup and configure the 2 Nodes Nutanix in our environment and OS will be ESXI .please need your advise by step by step. what are the prerequisites should I need to have. how many IPs i should need to connect from nutanix box to necessary devices Model :NX-6235C-G5 Many thanks in advance Ansar ali
I've inherited a Nutanix setup. I've noticed there is 1 Storage Pool setup and 4 Storage Containers. (see screenshot). I don't know what is the Default setup looked like so I don't know which are required. I'd like to have 1 container. Currently attached to Nutanix Host VDI_POC nutanix-peristent-pool Not attached NutanixManagementShare SelfServiceContainer All of my VMs are on the VDI_POC. Can I somehow delete the other 3 and combine them into the VDI_POC without losing data/downtime?
HI Trying to get a definative answere to what I think should be a simple question. Can I map a iSCSI drive to a Virtual Server by attaching a iSCSI Storage array ( Server has a Drive on the nutanix cluster and a second drive mapped to the exsternal array ( NTFS partitions on the MD iSCSI array ( NO VM's running on the array ) just mapping this as a drive [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/4831f6da-f541-4d2b-a407-0eabbb136259.jpg[/img] Would love to get a formal response from Nutanix if this causes issues within a cluster or will there only be issues with the specific VM's the mappings are assigned to ?
Nutanix best practices dictate that regular disk drives are configured on the SCSI bus, and CD-ROM drives are configured on the IDE bus. While regular disk drives can be configured on the IDE bus, it is possible that performance degradation may be observed on the drive due to the low queue depth on IDE controller. To avoid performance impact conversion of IDE to SCSI can be performed. Prior to modifying the IDE disk, take a local snapshot of the Guest VM, in case a roll-back is needed. It is strongly recommended that the VMs are powered off before performing the conversion. Convert the disk by cloning the IDE disk and attaching it to the SCSI bus. It is recommended to remove the old IDE disk after the cloned SCSI disk is created and validated. To help you identify any non CD-ROM IDE VM disks Nutanix has included NCC check uvm_ide_disk_check into NCC software package. This check is not scheduled to run on an interval and it does not generate an alert. Further on conversion steps, pre-
You have just configured the ESXi hypervisor in a Nutanix cluster, and now wondering about the recommended configuration?Below are the configurations which shouldn’t be altered in Nutanix HCI. NFS settings VM swapfile location VM startup/shutdown order iSCSI software adapter settings vSwitchNutanix standard virtual switch vmk0 interface in port group "Management Network" SSH enabled Host firewall ports that are open Wondering how to change the ESXi hostname and is it even supported?Absolutely yes, you can change the ESXi hostname Follow the KB Mentioned below Changing ESXi Hostname Interested to know more?

The business is growing, and this means more users, more virtual desktops, and you’re likely going to need more RAM. You could add a node or two, but what if rack space isn’t readily available? The existing nodes may still have room to grow. How do we add memory to nodes in a Nutanix cluster? The process for upgrading memory is covered in this KB: HW: Upgrading Physical Memory You should understand the restrictions and have a plan before purchasing DIMMs. If you need to review supported memory configurations, such as what DIMM capacities are supported and which slots to fill, check the NX Series Hardware Administration Guide for details. There are restrictions on mixing memory in the same node. You can’t just add any DIMM that fits into an existing node, but if each node has some slots available there are options to move forward. You could purchase new DIMMs to populate one node and complete this replacement first, and then use the removed DIMMs to add memory capacity to other nodes i
Hello Nutanix I am currently in progress of deployment of Acropolis File Services (AFS) Everything has been going well until the "Can't contact LDAP Server" error occured I have given it a check by viewing some configuration on NVM and found out that although on Prism, they have been assigned with 2 IPs but actually running with only 1 IP when checked via console by ifconfig command (eth0 only) Let me make it clearer via the "topology" below: CVMs connecting to NVMs by Subnet A IPs Clients, AD and DNS servers should be connected to NVMs by Subnet B IPs Recently, those NVMs are running with only 1 Subnet A IP although on Prism, I saw they have already assign with both Subnets?! My block is running with AOS 4.7.2. I have also given some seaches around and seen that both Internal and External networks could be the same as described in this video?!

We are fairly new to Nutanix. We have two seperate clusters in seperate datacenters. Our goal is to be able to move workloads between clusters based on needs and resources. We are using VMware 5.5 and everything seems to work as planned with the exception of the moving from cluster to cluster. We have cluster A and cluster B. We are using metro availability to sync the data from cluster A to cluster B at this time and that seems to work correctly. When I attempt to perform a cold migration from cluster A to cluster B I get the following error:Relocate virtual machineArtemisCloneFile/vmfs/volumes/ec936530-956aa-9ac/ArtemisClone/ArtemisClone.-vmdk was not found cold migration from cluster B to cluster A works fine. the whitelists are identical on both clusters. VMWare isn't really much help as their reply is to just browse the datastore and add it to inventory on a server in cluster B
Hi, we have installed a 4 node Nutanix cluster. In the installation process you have to select the cluster redundancy factor, RF2 or RF3. We tried to select RF3 but the system says that you need at least 5 nodes. So we were forced to create the cluster with RF2. In the future we plan to extend the cluster with additional nodes, may be only storage nodes. Will it be possible to upgrade from RF2 to RF3 without having to delete the existing cluster and create a new one? Stefano
Impact : If hostd service is not running, AOS upgrade will fail. Cause : VMware hostd service may not be running. Resolution : Check hostd status and restart it manually.

Hello community, I am facing a situation with some VMs, where the SSR-part of the Nutanis Guest Tools is causing some trouble. I have two VMs and created a Protection Domain for this to be able to play around with snap restore. One VM is working perfectly, the other VM displays: “Error executing command: Failed to query snapshot due to Nutanix Data Protection service error, error detail: Failed to fetch file information for VM with ID ****** due to hyperint error 1” This message appears as soon as I start the SSR tool or via ngtcli. Both VMs are set up the same way with IP from the same subnet. Can anyone push me in the right direction to have a look for an answer on this? Cheers Dirk
Hi, I often get the error of: Warning : Disk space usage for /home on Controller VM... Does anyone have a definitive list of what needs to be deleted beyond the installation files? or a script that deletes the un-needed files? Surely it is something Nutanix should be building in to the system, I never have problems with VMware running out of installation space! Thanks Eric
