Unable to remove crashed host from the cluster

I have a AHV host who crashed suddenly and does not want to start again 🙄.Like he is in a test environment i tried to remove it from the cluster with ncli command. Host remove-start id=0005f4c2-012c-5363-0000-000000019191::6 force=trueCommand failed because RF2 not permit to remove 1 of the 3 hosts cluster.I decided to reinstall this host with Foundation with new IP’s and new host name.Then, via Prism, i expanded the cluster with this new installed host.A new host appears to be added in cluster, but his status stays as “NEW”…I was hoping that by adding a new host to the cluster, I could then remove the one that crashed 🤔Why this new host stay in status “NEW”?Thanks for your help.

Does NGT fail to install on your Linux VM? Here's what I found...

If you’ve tried to install (specifically):CentOS Stream 9 Red Had Enterprise Linux 9.x server Debian 11and encountered issues with running the installer scripts, you are more than likely missing packages that the NGT install scripts are dependent on. Debian 11.xDebian was pretty simple to troubleshoot in my case. The setup_python.sh script would error in the first few lines. The first thing I found was that Debian 11 did not come preinstalled with bash, it only had a symbolic link that pointed bash => dash. So after installing bash and running the script with bash setup_python.sh, instead of the typical ./setup_python.sh, the script ran up until the next error which was thrown because the python tarball was failing to unzip. This was a result of xz was not being installed.Solution:# install dependenciesapt install -y xz-utils bash# from the source directory of the installer scriptsbash setup_python.sh CentOS 9/RHEL 9First thing I noticed again, was an issue with tar.

Is Foundation 5.5 compatibility with NX-1450?

I do a AHV convert from VMWare to AHV recently on my 4-node Nutanix NX-1450. Unfortunately only 2 nodes are successfully converted, one node remained failed and retain as ESXi and the other node failed to download the bundle binary. I wanted to reprovision from scratch using Foundation (Bear Metal Deployment) Tools. I have the Foundation 5.5 however, when provision it cannoy connect to IPMI (Error attached)so I an suspecting it is not compatible. Any body can help on this. If you have the earlier version of Foundation Tools maybe can help me?

"Move" a vCenter VCSA to a Nutanix AHV Cluster - how?

Hey all. I’m in the midst of testing “Moving” vm’s from ESXi to Nutanix AHV. One of these is testing the move of a vCenter Appliance to an AHV cluster. So far the VCSA does not come up cleanly, seems it loses it’s connection to storage/boot device. I’ve been trying multiple variations of the Move settings, in particular: Bypass Guest Operations on Source VM’s, Retain MAC Address and Skip CDROM AdditionHas anyone successfully completed a Move of a VCSA? Any hints/tips? This may be needed as we vacate ESXi clusters.

CVM can't ping other hosts in the cluster

I have a 3 node cluster with ESXI 6.7 and AOS 5.15.2. I’m unable to run any LCM tasks as the inventory fails to get the ESXI scratch space on the hosts. After troubleshooting SSH issues, I discovered I’m not able to even ping the other hosts in the cluster, via IP or hostname. I can ping the other CVMs with no issues, just not the hosts. However I’m able to ping each CVM and other hosts with no issue from the host itself, so the issue only exists when the CVM is the source and the other ESXI hosts in the cluster are the destination.I’ve restarted the hosts and CVMs and ensures the hosts are patched and updated. The hosts are all on the same subnet and no firewall exists between them. Any suggestions would be appreciated, thanks!

AOS (ESXi) and ROBO licensing model

Dear All,I’ve have a question about a licensing of the AOS (ROBO per per VM).Environment: vSphere7 (vCenter7 + 2-node ESXi clusters). Basically, fresh Nutanix cluster with HA feature enabled is hosting x4 “service” Virtual Machine:* x2 CVMs, x2 vCLS ( https://kb.vmware.com/s/article/80472 )As far I understand CVMs don’t need to be covered by the ROBO license, but what about a vCLS? How AOS is qualifies vCLS: as a service or a “standard” VM?Also, do I need ROBO license for the powered-off VMs?Regards,Dominik
