Segmenting Stretched Layer 2 Network for DR

  Hello, As part of our Metro availability setup (two Nutanix clusters with 10 nodes per site), we plan to implement network segmentation for DR traffic and storage/RF traffic on each cluster. For the DR traffic, the guide suggests you can use a stretched Layer 2 network configuration without requiring a gateway. This is our preferred approach, to have one VLAN/subnet stretched across the sites dedicated to Metro traffic. To set this up, I plan to:In Prism, create the IP pool using half the subnet and specify the service being isolated (in this case, DR). Specify the port group in ESXi to be used for DR traffic. Repeat the same steps on the other cluster, using the upper part of the IP range. Specify the same port group used in step one. Run the commands outlined in the KB below on both clusters.https://portal.nutanix.com/page/documents/details?targetId=Nutanix-Security-Guide-v7_0:sec-network-segmentation-enable-l2stretch-ns2-t.html My questions are:Are my steps correct? Why do I need

ESXi Networking in Metro Configuration

Hi all, I'm in the process of creating two new Nutanix clusters and configuring Metro availability for replication. Our network uses a spine-leaf architecture, with 10 nodes on each site. Latency for site-to-site connectivity is under 5ms VLANs can be stretched between sites for seamless failover of all VM workloads. Additionally, I plan to use network segmentation to isolate storage/RF traffic for each cluster. I’m aware the all ESXi hosts need to part of the same ESXi Cluster for a supported Metro Availability configuration.I would like some advice on whether the ESXi hosts should be on the same stretched Layer 2 network or if they can be independent. For example, having ESXi hosts on site A use 192.168.5.0/24 and ESXi hosts on site B use 172.16.2.0/24.Are there any downsides to this approach? It feels more straightforward not to stretch the VLANs for host management networks. Has anyone else managed something similar? Any insights or best practices would be greatly appreciated. Than

Delete all Storage Data

HelloWe have a Nutanix cluster that we decomissionned, we want to delete all the storage data before unplugged it, but for some reason after deleting all the VM the storage cannot be deleted because its say there file on it (I check on with winSCP and nothing present on one of the storage, and on other its old snapshot associated with no vm.How can I delete all the stuff within Nutanix?​​​​​​​

Nutanix community edition 2.0 installation on bare metal, network does not come up

Hello community,I’m attempting to install single node AHV server with CVM on bare metal rented from CSP. The hardware compatibility is confirmed from the AHV HAL. Following the guide, I was able to complete the installation however the networking isn’t getting configured correctly. Seeking help in debugging and resolving the issue. Issue: After installing Nutanix Community Edition (CE) 2.0 on bare-metal, the network does not get configured correctly. Inbound and outbound connectivity with AHV & CVM not working.Procedure Followed:Downloaded the Nutanix CE 2.0 ISO: phoenix.x86_64-fnd_5.6.1_patch-aos_6.8.1_ga.iso. Installed using IPMI interface on the physical server. Uploaded the ISO and followed the bare-metal installation instructions outlined in the official deployment guide: Nutanix CE Deployment Guide. During setup, configured the IP and gateway details for both AHV and CVM. The following were assigned: AHV: IP:  (Public IP) DNS: 213.186.33.99 Subnet Mask: 255.255.255.0

External networking (not working)

Nutanix external networking seems to be broken. I’m installing on a dell R730 with multiple networking cards and LOM ports. I can only get to the system via idrac. I can't seem to ssh to ahv or the cvm. I can't browse to http:// management_ip_addr either. I have no way into the system other than idrac.Internal networking seems fine. I just can’t go external (ex. ping gateway) My thought is that there is some sort of disconnect between the virtual networks and the physical ports. For example, in VMware you need to select the right physical port for your virtual management network. I reinstalled 4 times on bare metal and don’t have any instructions wor selecting physical ports.

Nutanix CE 2.0 3-Node Cluster Destroy Stuck

Hello everyone, I have been trying to deploy Nutanix CE 2.0 in VMware vSphere - I am using 3 VMs and the idea is to make a lab environment to test the services that Nutanix offers. I hit on a rock with the creation of the cluster. First I noticed not enough CPUs were allocated for the CVMs, I now have 4 vCPUs for each CVM, the storage is 64 GB, 200 GB and 500 GB for each VM. My services weren’t coming UP and I got error from Medusa service about a Cassandra failure. I checked that an NTP server problem may be behind this error. I wanted to destroy the cluster in order to start again and add an NTP server to the cluster itself. Well, I am stuck now on “Destroy is in progress on the nodes: [cvm1, cvm2, cvm3 ip addresses] for more than 4 hours. I cannot either start the cluster, now that it is in “stopped” state, I cannot cancel the destruction and I cannot create any new clusters… Some services are still staying UP like Zeus, Xmount, Scavenger, but the others are DOWN.I tried various com

Nutanix CE 2.1 - Prevent Stargate from consuming spare CVM storage

Building a (3) node Nutanix Cluster for HomeLab/Education/Migration away from VMware.  Hardware:(3) HP DL360  w/  (3) NVME devices:(2) Samsung 256GB NVMe(1) 3TB Oracle/Samsung F320 NVMeCan successfully build the cluster and consumes the 3TB F320 devices correctly but also consumes the spare capacity from the CVM (marked at install) SSD.The norm is to consume all available SSD space but in this case I am concerned about wear level on the CVM marked SSD where the F320s were designed for high PBW.My preference is to only use the F320s for all storage operations and “block” the CVM spare capacity from being used in the default storage pool. Thank you in advance!

Unamed PC with 2 named clusters attached

Hi,I have 2 x 3 node clusters managed by a single Prism Central,  I have recently tried to upgrade the PC and it does not like the fact it is unnamed it has only a virtual IP - also with no entry in DNS.  So the terminology is confusing me a bit, to add a name to PC it requires the cluster name - is this a PC Cluster name, different to the 3 node cluster names?  or something else?  If I add an FQDN now will it break my existing clusters? ThanksEric

Nutanix Cluster Upgrades and Configuration Issues.

Hello Community.New to the Nutanix world here. Busy setting up a multi-cloud 4 node environment for our clients. We were experiencing a number of issues and attempted upgrade to PC 2024.2; from PC 2024.1.0.2. This has introduced a number of further issues, and I am suspecting underlying compatibility issues in the environment with the new release.Any guidelines or assistance from the community as to getting the platform stable and running optimally again. I am hearing and seeing that a fairly strict upgrade process should be followed to avoid such problems, any input here would also be greatly appreciated.Look forward to hearing from you guys, and thanks.Mark

API / Script for Automating NGT Download

Since we can now download NGT through here: https://portal.nutanix.com/page/downloads?product=ngtI was curious if it was possible to have a script automatically download the updated file every time it releases. I know we can do API in the Nutanix environment but wasn't sure about the portal. Or if anyone knows an alternative approach, please let me know.
