Reduce Prism Central VM size: fewer vCPUs and less RAM

After I tested different features about Prism Central I’d like to reduce the size of the VM. Now the VM has 18vCPU and 70Gb RAM, it’s to much for my normal use. Is it possible to reduce the vm?

Powershell cmdlet Connect-PrismCentral is failing

I am working on converting my scripts to Powershell 7.x. I tried to use the Nutanix cmdlets 2.0.1 provided for Prism Central. Attempting to connect to Prism Central is failing.

Installing Nutanix CE 2.0 Test Bench Server

Greetings All,I am new to the Nutanix world (VMware refugee). We have a small vSphere deployment with 3 ESXi hosts (6 functional guests) being backed up via Veeam (on-prem). I am considering replacing this with Prism and AHV also backed up via Veeam. This would seem rather straight forward but it is not proving to be at the moment. Working with the CE installer and following along with the YouTube video by Nutanix University I keep getting stopped by various issues that do not align with what seems to be known issues. The first was the Realtek driver (I deactivated the onboard NIC and replaced with an Intel Server NIC). I am able to ping the AHV but the CSM is not running so I cannot get past the 6:50 point in the video which is ping the CSM. I should mention that I selected to install the AHV to nVME1, Data to nVME2 and CSM tonvME0. Interestingly if I altered the devices, I ran into different issues like first boot failures so I am wondering if there is a communication issue with the

Unable to install Enterprise or CE

Hi Next!I've been trying to deploy Nutanix on three HPE DL380 G10 without success.Hardware config is exactly the same on the 3 nodes, 2 x Platinum 8260Mm 1 TB RAM, 6 X 3.82 SSD drives, 4 port onboard 1 Gbps NIC (not used), 1 x Infiniband adapter (not used) and 2 x 2 port HP CN 1100R 10Gbps SFP+ cards. All firmware update with latest available PSP (september 2023). First tried Foundation, version 5.5 with installer package fraser-6.5.5.1 and with either ESX 7, ESX8 (HPE Cutomized ISOs) and AHV version integrated in the installer package. Foundation timeout after several retries, and checking iLO server console looks like the installer is not able to assign IP addresses to any network interface so foundation VM is not able to contact the server. If I try to manually assign IP addresses after foundation fails it returns an error indicating that eth5 to eth8 (10 GBps ports) file is not available. If I try to deploy using phoenix ISO (created from foundation VM / with ESX and also with AHV)

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.

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!
