Installation & Configuration

I know that this question has been asked in this forum a few years back but I wanted to see if the answer changed since the newer releases of AOS.  In my case, I’m running AOS version 5.15.4 LTS and found that our 7-node cluster was configured for RF3 - although most of our containers are RF2 (the exceptions being the “NutanixManagementShare: and “SelfServiceContainer” containers).Since most of our containers are only RF2 I’m not too concerned about extra overhead but was curious if AOS now supports the switchback from RF3 on the cluster. 

From the AHV Best Practices document,  live migration network is in host management network(br0).In the network segment enviroment, backplane is isolated in another network which maybe has high bandwidth, does the live migration has any change under this condition? or Live Migration network can do some setting like ESXi vmotion network?

Hello,I'm trying to setup four nodes on Lenovo HX3321 with vm foundation, but the vm foundation is not start.We have  verify the address vm foundation is correctvm foundation and IPMI same network can you help !!thanks. 

Hi all,How many blocks can be added in one rack? I mean min and max numbers.Thanks in advance.

I have a cluster of 6 nodes including 3 nodes 1065-G5 and 3 other nodes 1065-G6 which run a hyper-v.I wanted to update from Aos 5.10.5 to 5.17.1 through LCM but I am having issues with the processors.I therefore want to proceed node by node in maintenace mode.Can you give me the procedure for updating the aos by proceeding by this method?

after  change IPMI i found warning IPMI not match I see the reference https://portal.nutanix.com/page/documents/details?targetId=Hardware-Admin-Ref-AOS-v5_17:ipc-ipmi-ip-addr-change-t.html how to step genesis restartI must stop cluster before ?i can run command genesis restart when cluster start ? Thank for support 

Please advise me is it support Server 2019 Hyper V on Nutanix? I unable to Find the article on Nutanix Portal with server 2019? I am planing to migrate from Server 2012 hyper v failover cluster to 2019 Server Hyper V failover Cluster? Which AOS Version is support Server 2019?

I have a couple of oddities going on, one is an ongoing and one was post latest PC2021. update.I was getting warnings that I was using the CVM default password so I chnaged it, it is supposed to replicate to the other CVMs but i get a health alert saying the remaining CVMs are still using the default password - any ideas why?And post PC update, i can log in using ssh but I can’t login to the web UI - I get the login screen , but after I enter username and password (not default) I get “server not available”  I have run health checks and idf checks and all seem to PASS - is there a bug in the latest PC Patch?  Just to note I can log into Prism Element with my name and password ok.Thanks in advance.

Hi,I have a small cluster of 4 nodes. Disk space usage for /home in all CVMs are increasing fast. After some investigation it appears that the /data/logs folder is taking majority of space, more specifically health_server.log file which is taking about 181gb now. 18133488        health_server.log.20201224-1413011144624 sysstats Does the health_server.log file keep collecting indefinitely, there must be a limit to this log file? Thanks.Beg

Hello everybody, i would like to remove a switch from the Network view in Prism Element, which also is no longer configured under Settings => Network Switch. The cluster was moved to different network a couple of months ago. So far I was unable to remove this old network swith from the Network view in Prism Element and it’s also no longer visible using ‘ncli net list-switch’ in CVM command line. There is only the existing switch configured under Settings => Network Switch. We use AOS 5.15.4 LTS currently. If I select ‘Go to Switch details’ when selecting the old visible switch in ‘Network’, I get an error => Switch with id ‘...’ was not found ! Any idea how I can remove such a switch, which is no longer available? Regards,Didi7

Hi All,How to Migrate Clusterd VM (SQL CLUSTER) from 2012 Hyper V Failover cluster to 2019 Failover Cluser?Source Infra:Hyper V2012 with Failover ClusterVM : 2012 VM (SQL Cluster, Shared Disk) Target Infra:NutanixHyper V 2019 

Dear All,Can we use 1 G port for Hyper VM Traffic on Nutanix?

UPGRADING SERVER FIRMWARENutanix recommends that you use the Service Pack for ProLiant® (SPP) ISO file for applying firmware updates. Perform this procedure on every host in the cluster, one host at a time. About this taskTo upgrade the firmware on a server, do the following:Procedure If the server is part of a Nutanix cluster, place the server in maintenance mode.Information about placing a server in maintenance mode is available in the host management section of the Acropolis Command-Line Interface (aCLI) documentation. See the Command Reference for the supported AOS version. Turn on the server to the SPP ISO. Connect to the iLO by using the iLO IP address. Log on to the iLO user interface by using the administrator credentials.The default administrator user name is Administrator on all HPE® ProLiant® servers. Passwords for the iLO administrator differ from one server to another, and are available on the service tag on the server. Attach the SPP ISO to the server by usi

I have read the documents and manuals of APC PowerChute Network but it is a scenario that doesn’t apply to mean. Apparently, someone sold to the customer a Vertiv Liebert GXT4 UPS. Liebert’s engineers concluded that the product couldn’t provide a graceful shutdown of the Nutanix cluster, while it could shutdown the ESXi on top.Is there anyone out there who had succeeded in performing a graceful shutdown without APC?

We are planning to add new nodes to existing clusters.Before the extension, proceed with the new Node AOS install (Bare metal image) and then add.At this time, I want to know if there is no problem if the existing cluster AOS and the new AOS are different versions.ex) Existing Cluster AOS 5.10.9 / New Extension Node AOS 5.15.xPlease give me some advice.Thank you.

vCenter 7.0U1c and vSphere Clustering Service VMs on local or shared storage.After test upgrading vCenter from 6.5U3 to 7.0U1c (which worked just fine w 0 issues), every vmware cluster with DRS and/or HA enabled gets 3 new vCLS (very tiny VMs w 2GB storage/.13GB RAM).When NCC is ran it registers 3 WARNs that there are VMs running on the SATADOM’s. I would assume that, even what (little) they do (today), would this wear out Satadom’s or M.2’s?Would this be a concern for G4/G5’s (w Satadoms) and not G6/G7’s (M.2’s)?”While vCLS can be moved to shared storage, wouldn’t they be moved back to local storage during an NX cluster stop?(Like to point out this was done in a LAB environment, not in Production… no bits nor bytes were harmed during the upgrade progress.)

Added 9 nodes(AHV) to existing cluster successfully and when i try to verifyLACP status with command (hostssh "ovs-appctl bond/show br0-up" | egrep "===|lacp_status") it is showing LACP status off.Steps i performed before adding the nodes to existing cluster1.Configured network on all 9 nodes2.Configured LACP on all 9 nodes Please advice.  

How many nodes we can deploy at the same time in nutanix ? Is there any limit or shall we just go ahead and deploy all the nodes at the same time ?Same query is related to cluster expansion, can we add multiple nodes at the same time in existing cluster ?Thanks

I’m new to Nutanix so bear with me if this has been asked. Is it possible to simulate a x-over cable between two VM’s? basically I want any traffic leaving a load balancer to be passed via layer 1-2 to a WAF appliance so it can be inspected. The WAF is in transparent mode and won’t have an IP Address. In the past with physical machines i would just cable them inline. 

Hi All,Current environment (~40 sites & HO) do not have any 10GbE switches and we are planning 2-node clusters per site. If using 2 x 1GbE Nic for the management like a witness communication, can we connect ESXi nodes using  10gbit ‘direct cable’ to support the workload for all VM traffic, vMotion, vmKernel, and Nutanix and most important, two node disks datastore? It should be not any issue for the Nutanix/VMware level, Switch is on L2.

Can I change IP or VLAN in IPMI after Foundation that will be concern or affect to AHV environment?

I feel it is time to address a seemingly minor question: should you re-image your nodes when re-using them from an existing cluster? To give a better idea of a setup, think of a cluster with eight nodes, for example. You would like to scale down the cluster and re-use 4 of those nodes to form another cluster. You have evicted the nodes, and you could create a new cluster at this stage but let's take a look at the pros and cons of rushing forward.Cluster creation does no wipe the system. All the files on the nodes remain as they are when you trigger cluster creation. That sometimes can mean issues with LCM upgrades or the cluster creation may error out. To resolve those issues you would need to find those files and chances are you would need a Nutanix Support Engineer to deal with that.Some features introduced in software releases are only available if the version is a fresh installation rather than an upgrade.Any networking changes you might need are easy to apply during the foundation

Hi,Is there any ETA for Nutanix Guest Tools for Debian 10? Debian 11 is probably going to be released this summer, so it would be quite nice if NGT supported Debian 10. Or is there a way to “forcefully” install Nutanix Guest Tool on newer systems? Is it possible to build it ourselves to we can distribute it on our thousands of VM’s that is running?
