Installation & Configuration

I’m about to upgrade vcenter from 6.7 u1 to 6.7 u3. I’m only upgrading the vCenter for now. My AOS version 5.10.8.1 To upgrade only vVenter is there any action to take in PRISM? Will there be any impact on PRISM?   Thanks

Quick tip of the day. Did you know that you can integrate IPMI with the Active Directory?   Note: The default timeout is set at 0, which results in an error message HTTP 500 - Internal Server Error. Make sure to update it to 10. Select the User and then select Add Role Group to configure the Role Group. (Be sure that it matches an existing AD group name.) When logging into the IPMI web console, use the following format to log in: username@domain. Should you find yourself with a task too big to be handled manually such as configuring the same but on a miriad of nodes there is some help available. SMCIPMITool is a ut

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 passwo

Hi All I have created a MS server 2016 VM with a view to using it as a desktop , however it does not seem to have away to add anaudio / soundcard device - is there a way to add one in Nutanix?  I have found a way in VMware but not Nutanix. Any ideas? Thanks Eric

Wandering if someone could point me in the right direction as I am not overally familiar with SUSE. I am replicating from ESX to AVH and have installed NGT. The guest fires in AVH but I have no GUI - it errors that there are no drivers for X. Unfortunately it is stuck in my DR segment for which I only have the Nutanix Console access to at the moment, bets I have is:   Just wandering if anyone had any experience with SUSE / AHV and could point me in the right direction? If I run startx from the console I get no screens found:   Any assistance appreciated.

Playing around with an old NX-2000 series server and it seems I need to make my 10GbE nics default to eth now while before on boot they seemed to be recognized in eth mode.

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.

Hello all, I’ve tried to install ESX 6.7.0 and AOS 5.15 onto my Nutanix but it keeps erroring out. It looks like it’s trying to mount a phoenix.iso but that file does not exist and isn’t being created during the install. Leading to Foundation to be unable to SSH to it after boot. Please assist.

I want to test Microsegmentation on prism central, but "AHV Free Memory Minimum 1GB for each Prism Central VM" showed up. And I can't enable Enable Microsegmentation check box. 20gb memory assigned to prism central. What was the problem ?    

Has anyone else had an issue with installing the lated CE image on esxi7? It seems to shutdown after the hypervisor is created and begins the startup. After you reboot and attempt to run it in regular mode I get this message:   If I go into safe mode I get the login prompt with the host name configured:   I performed a “virsh list --all” in safe mode to get the following:   When is attempt to start the vm in safe mode, the host machine shuts down:  

Syslog or ‘System Logging Protocol’ is used by routers, switches, access points, servers and of course Nutanix. It is used to send events and logs to a remote syslog server that collects, organizes and filters these logs.    In Nutanix, we provide different log modules for the core services that can be enabled separately and you can configure the logging level required for them as well. For example, if you wish to forward just the warning log messages for Acropolis, this would be the command: ncli rsyslog-config add-module server-name=<server_name> module-name=ACROPOLIS level=WARNING   For a more comprehensive look at the various modules and log levels, check out

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 us

Hi guys. We are in the process of acquiring Nutanix products, but we need to know something crucial. We currently have more than 100 ESXi hosts, separated in 2 sites. We have a metro cluster, all the datastores are sync, this is full active active, with EMC VMAX All Flash and VPLEX. As of today (May 2020), can we do such thing with AHV and ADSF? It is supported? I’ve seen the Sync DR here: https://cloudvm.es/nutanix-ahv-synchronous-replication, where i can see you can do it VM by VM. But what about if i want to protect at datastore/container level? All of the VMs. We have more than 3000 VMs. We need to know if we can accomplish the same with Nutanix. Stretched storage and VMs on both sides, for obvious reasons (balance, availability). If one of the sites crashed, HA all the VMs automatically to the other. Is there a video or pdf show

Hi, New to the forum, we recently had our Nutanix servers delivered and we are planning to do the install in the coming weeks. We haven’t decided which hypervisor to go with yet its either going to be Hyper-V or AHV. I just wanted to know peoples experiences that they have had? We currently use Hyper-V, so we are comfortable with that but all the nice features seems to be heading to AHV/Prism. I would be grateful for your thoughts and comments Thank you

I have a problem with OS and Distributed Switches on vCenter. When I migrate the vm-network from standard switch to distributed switch show the next error: Detailed information for cvm_startup_dependency_check:Node x.x.x.x: FAIL: .dvsData directory is not persistent yetRefer to KB 2050 (http://portal.nutanix.com/kb/2050) for details on cvm_startup_dependency_check################################################################################PLUGIN RESULTS################################################################################/health_checks/hypervisor_checks/cvm_startup_dependency_check    [ FAIL ] I can see that when reboot the ESXi host and start the CVM I lost it network config on the CVM, and I have to assign again network adapter on the CVM. I don't know how configure on the vcenter the distributed switch to make persistent.

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

Hello, I am new and I am interested in whether Nutanix acropolis supports Atlassian products Bamboo, Bitbucket, Jira? Does anyone have experience with their containers on the Nutanix platform?

Here’s my problem. Node A & B are synchronizing to the wrong host. Node C is synchronizing to the right host. This is the behavior I see on the CVMs. When I do “hostssh ntpq -pn”, the hypervisors (AHV) are reporting the correct ntp server. How do I bring nodes A & B back inline to what they should be? I tried manually correcting their ntp.conf files with the correct IP and restarted the ntpd service. No change and eventually the ntp.conf files changed to the wrong settings. Not sure how to wrestle this one to the ground.

Hello guys,   currently i deployed a new hpe hardware Hypervisor version is  ESXi VERSION 6.7.0   I need a vcenter to deploy some VMs in Nutanix, so i downloaded the vcenter applicane and tried to run the setup with admin rights.   I have currently no dns server, so i used the gateway. NTP server is currently not available, because the environment is completly new, so i used the Time-synchronisation: Synchronize time with the ESXi hostSynchronize time with NTP servers    Its activated with http://de.pool.ntp.org/; but is only temp.   The vcenter appliance setup 1 is running fine, the step 2 is very slow and need much time. After 2hours on 50% i canceled it.   The error:   N

esxi 6.5 u2 vSwitch configured as 1 active uplink and 1 standby uplink on esxi nutanix. I didnt understand why the standby adapter in which scenarios. I wonder why and in what scenarios it is used. can i use both 10 GB network adaptor active-active mode in Virtual Standard Switches (VSS).   

In this topic I will share how to configure an SMTP server on your Nutanix cluster. This can be done from the Prism UI. This is pretty simple and straight forward.  Below is the link shared, that discusses how to configure a SMTP server- https://portal.nutanix.com/#/page/kbs/details?targetId=kA032000000TTWtCAO After the SMTP server is created, the email alerts should be tested if they are being sent from the cluster. SMTP always uses port 80 and 8443, so make sure that these firewall ports are open. You could send test emails to verify correct SMTP configuration. This can be done using the KB2773. I will attach a link to the KB below. https://portal.nutanix.com/#/page/kbs/details

Hi, everyone I’m trying to use LCM to update firmware of host machines on my cluster. It all went well until the post action phase. Error message said: ‘Operation failed. Reason: LCM failed performing action reboot_from_phoenix in phase PostActions on ip address xx’. I searched the KB and found KB9177，but it’s about ‘Mixed Hypervisor cluster‘, my cluster uses solely AHV so it doesn’t applied. Anyway I still tried to follow the KB9177’s suggestion and upgraded my cluster’s foundation to 4.5.3 and retried the LCM firmware update process on another host but still got the same ‘ LCM failed performing action reboot_from_phoenix’ error. I used the workaround provided in that KB to make the affected two hosts’ CVM out of maintenance mode. It works and the cluster is back to normal. Then I logged on to the affecte

Hello, for LCM updates I see that pre-checks require DRS in fully automated mode. It’s possible to perform LCM updates without DRS in fully automated mode (in the event that a customer does not have DRS in his licenses) ? Thanks Manuel

Hello, We have a cluster with 4 nodes and I will perform the update from 5.9.4.2 to 5.10.10.1. a some minutes ago, I see that my cluster have a disk space problem and the resilience board is red with the “not resilience” information. In this case I will have a problem when perform the AOS upgrade? I not have time to resolve the space issue now…  Please, send me any information.

I’m trying to setup a new bridge (br1). After ssh to the Nutanix AHV,  I continue with input “ssh root@xxx.xxx.xxx.xxx” to get to the CVM,  it ask me for a password.  Is there a way to change/ continue with a different logon name as well at that? The password I input is being denied due a different username for the CVM.
