Installation & Configuration

Your hardware lease period is expired, and you have tried to destroy the cluster to clear the data off the cluster, but the cluster was not destroyed completely? Successful cluster destroy requires to have a clean environment. Clean out cluster config and cluster data. This operation will completely erase all data and all metadata, and each node will no longer belong to a cluster.  There are some situations where cluster destroy does not succeed, especially if cluster destroy is executed while one of the nodes is down. In that case please follow this document  KB 3436 [Forcibly Destroying the Cluster Using the .node_unconfigure File] which can help you further to clear the data from the cluster.  

My stargate contimues to restart. and I cannot find anyting in the GUI to indicate what it my be. When I get in the cli, i see the cluster says all four nodes are up. i try to ping 192.168.5.1 and the icmp request never completes. pinging all other ip’s work as expected. my esx is 6.5u3 aos is 5..5.5 my NCC is 3.7.0.1 foundations is 4.3  

Hi there, I am new with Nutanix and I have a doubt about Acropolis licensing. We have 3 nutanix nodes with Acropolis Start Edition installed. Yesterday, my PRISM console report a License Feature Violation. Looking at https://www.nutanix.com/products/software-options , the only thing that I saw that could be wrong in my configuration was a Volume Group created for a test. Just to be sure, in an Acropolis Start Edition can we create volume groups or this option should only be used in PRO and ULTIMATE editions? The alert don’t give me more information about which feature is violating the license. Thanks in advance for the help! BR, Thelmo    

Hello everyone, I'm having problems with the cd-rom assembly in all my VMs, I can't add it with an * .ISO image, and I can't remove or disassemble the existing cd-rom, can someone help.

Working using CLI is easy, simple, elegant and fast. Every administrator loves scripting and automating tasks using the command line. Nutanix makes Management tasks related to virtual disks easy, simple and efficient using CLI. So, what are the situations in which you might need to perform VM Disk management actions if you’re an administrator? You created a VM with a disk of 250GiB and now you need to increase it to 500GiB What if you need to increase the size of a VM Disk? Created a Disk but now need to clone it to different VMs! Need to create an image from a VM disk? Created a VM with the wrong BUS Type! Do we need to change the index of IDE disk? We all have faced a situation in which we might need to insert an ISO to a CD ROM or eject a CD ROM We have created a Volume Group and now need to manage the disks in the VG Most of these actions can be performed using the Prism GUI but what if we are more interested in CLI approach and want to automate these day-to-day admin tasks Do we

Hi Guys,   i have some questions, first, can we enable flow on ESX hypervisor on nutanix? i have same question with calm on esxi and i get the answer we can enable calm on esx based on nutanix KB, but how about flow? can we enable/using flow on top esx hypervisor?  and just courious, anyone have table comparation about feature nutanix running on ahv, esx, hyperv?

Howdy,   I’ve searched through all corners of the web, but still didn’t find a clear answer to this question: can Nutanix prioritize packets and/or traffic in OVS? And, if yes, is there some online how-to that I can refer to to learn how to do that?   Thanks in advance,

Howdy, I already know that Debian is an unsupported Linux distribution for using NGT on. But I still *must* try NGT on it... how can I force the instalation of NGT on Debian?

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.

We all have encountered file system corruption in our environment and sometimes it can bring down the entire production architecture.  Do we have a mechanism to proactively check for File System corruption in a Controller VM irrespective of the hypervisor? Nutanix Cluster Check has a specific check “fs_inconsistency_check ” to look for EXT4-fs error/warning in system logs periodically and inform the end-user.  Need more information regarding the Check? Try giving the following KB article a read. KB-8514 So, what should we do in case NCC Health check reports the error? The article mentions steps to identify if it is a false positive or we need to reach out to Nutanix Support with a particular log bundle. KB-8514 Need more help regarding an NCC Health check or confused regarding the same? Drop a comment and let’s start a conversation.  

Hi AllAfter upgrading the NCC version, I get this message CVM was renamed after installation - I haven't changed it!  The recommendation is bizarre - Rename CVM back to its original name.  CVM name is noncofigurable by the end user.So if it is non configurable , what changed it and how do I get it changed back ?  Or is it just having an identity crisis?Is there a fix?

If your company hardening policies require to show the welcome banner on each CVM each time a user logs in, you can disable it, make the necessary changes per our Security Guide (https://portal.nutanix.com/#/page/docs/details?targetId=Nutanix-Security-Guide-v5_16:Nutanix-Security-Guide-v5_16) and then reenable it. The following KB 8534 has the complete procedure and the commands needed to apply the banner changes in your environment.

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 

I’m trying to reconfig my ip addresses for the cvm but i cannot find the external_ip_reconfig script anywhere.  Do I have to download this from the site?

I have a cluster running on an NX-3060-G5 with XenServer hypervisor that I want to completely rebuild on Acropolis. I’m looking for documentation on how to do this. Our original cluster was built by a Nutanix engineer onsite and I recall he had to install the foundation software on another machine, but I don’t recall all of the steps he took. Can someone point me in the right direction? 

I'm will be configuring Network Segmentation on my Nutanix Cluster as per these instructions. https://portal.nutanix.com/#/page/docs/details?targetId=Web-Console-Guide-Prism-v510:wc-network-segment-on-existing-cluster-wc-t.html The VLAN that I put my backplane traffic on, does it matter or not if I have a Gateway for that VLAN? I would use 172.16.10.0 as the Subnet IP and 255.255.255.0 as the Netmask. I am planning on having a Gateway of 172.16.10.1 on the firewall. Currently, the default configuration without network segmentation, the management and backplane traffic on eth0 has a gateway so as far as I can tell, everything should still work if I have a gateway for backplane traffic. Could someone please confirm that it doesn’t matter if I have a gateway on the backplane VLAN or not?

Dear All Is there any limitation for Nutanix to hold more than 64TB storage in a single node ? Pls send me the refference link

Security and encryption are backbone of an IT infrastructure. Many organisation have made it a compliance to encrypt data and keep the data on-prem. Nutanix also provides industry standard security features. One of them being :DATA-AT-REST ENCRYPTION Nutanix provides an option to secure data while it is at rest using either self-encrypted drives or software-only encryption and key-based access management (cluster's native or external KMS for software-only encryption). Want to more about D-A-R-E and it’s features? Go through the following guide D-A-R-E guide    During various compliance auditing and administrator task, we need to verify if D-A-R-E is enabled and successfully working or we need to configure D-A-R-E How can we safely accomplish that? We have different methods using which you can verify that D-A-R-E is enabled or not . You can use these methods to automate the process of verification or configuration. Go through the following KB to know about the various methods with comm

Is it necessary to have 2 vlans when deploying nutanix or can I deploy nutanix with one vlan?

Hi, I am new here and this is my firts experience with Nutanix. I need to deploy 3 nodes, and I’ m going to use the native Hypervisor from Nutanix (AHV). I saw a video explainning that,  to do it, it’s necessary to download and use the Foundation Tools to configure the cluster and than, gathering access to PRISM. Unfortunally, I can’t download Foundation, due to the Nutanix blocks were registered by our customer (message: ...The email XXXXXXX is not authorized for the account associated with the serial number YYYYYYY) and we don’t know who did it. We are trying to identify who registered the blocks but, meanwhile, Is there another way to deploy it without the Foundation tool, or is there a way to unregister the blocks and register again but to different user account?   Thanks in advance,

I completed an AOS upgrade from 5.5.2.2 to 5.10.8 on two different clusters.  On one cluster I have the health page showing a warning symbol (no data) and the message: “An error has occurred. Show me why” When I role over “Show me why” I see the message “java.lang.NullPointerException”.  I have a ticket open with Nutanix but haven’t received any solutions that have worked yet. Appreciate help if someone knows how to resolve.

When i try to connect to IPMI by clicking on the link in Prism Central i get an error stating the site can not be reached because it timed out.  It seems to be related to the firewall maybe.  Any information where to start? thank you

Hi, We have a NX-3060-G4 with 3 VMware hosts on that is currently connected to our Cisco core switch cluster using 10GB twinax cables. A long story short, I need to remove these and connect the NTX to a single 1GB Cisco switch (WS-C3850-12S-S). My question is: can I connect a 1GB SFP link between the NTX and new core switch using the 10GB NTX ethernet port? If so, will the NTX detect that the cable connected can only run at 1GB?   Thanks in advance.
