Deployment Success

Hello Community, hope you are all doing well.  We have 8 NX-3155G-G6 nodes and Each node has 4 x 8TB HDD and 2 x 3.84TB SSD.We would like to add new disks to expand to storage Capacity. After checking this link , we noticed that there are 6 empty drive slots on each node and it is not clearly specify how to fill them (please have a look on the picture below).What are the possible layouts to add new disk to populate the empty slots ? Thanks in advance.

Hello together,i have followed the installation guid:https://portal.nutanix.com/page/documents/details?targetId=Nutanix-Community-Edition-Getting-Started-v2_1:top-login-wc-ce-t.htmlnow the only thing left is to connect via the web console but the browser cant connect to it it refuses the connection due to timeout. Do i have to aktivate the web console first or is there any config that i could have missed?

Newbie trying to configure Nutanix.Setup:Dell server with iDRAC VLAN’s are setup on the switch Nutanix is installed. Both the Host and the CVM have an IP address in the same VLAN (100)Questions:Should I configure the VLAN on the CVM first or on the host? It seems if I configure the CVM first I can then configure the host. If I configure the host first I can’t get to the CVM. (expected) When I configure the CVM it never seems to return so I have to hard reset the host. Setting the CVM tag back to 0 it does come back.Commands:On the host: ovs-vsctl set port br0 tag=<vlan tag> On the CVM: change_cvm_vlan <vlan tag>

Hi all, new to Nutanix here likely for the same reason a million other folk are trying it out. I’ve managed to find the download (though not exactly straight forward) for Phoenix 6.8.1 CE and am attempting to first time install on an r820 with 5 enterprise ssd sas in front bay. I’ve split the first off into it’s own virtual drive at full capacity (300something gb) for H install. The second and third off into their own individual virtual drives for CVM1 and CVM2. Then the last two combined into one virtual drive for D.  I am able to select the virtual drives for H and D however the CVMS tell me it can’t be selected because the drives must be SSD which they are. Drives are fine and the virtual disks are recognized just not allowed to be selected. Any insight is greatly appreciated I’d love to test Nutanix out but documentation has been all over and even downloading (from a link in a seemingly random forum post) my confidence is a bit waned.

Which command can administrator can run to find the correct VLAN ID from the CVM?manage-ovs ovs-vscl

It’s been running for 21 hours. Is there a way to stop, delete so I can re-deploy? Thanks

Hello,I am attempting to deploy a Nutanix CE virtual machine on KVM; however, I am encountering the following error:  Upon investigation, it appears that the installer is attempting to access certain system information from /sys/class/dmi/id within the VM, but this data is unavailable.I have made several attempts to pass this information using virt-install, but these efforts have not been successful.

I have learned that Guest VMs transmit data to AHV and AHV reroute data to CVMs. Then, CVMs transmit data through PCIe passthrough (I haven’t got this point because CVMs still VM. so, it can’t bypass its hypervisor) to HBA hardware. After that, HBA transmits data to disks. But I want detailed data flow that explain hardware and software (like Curator, Medusa… etc) data flow from guest VM to the disks because it will be useful for troubleshooting and confidants while working with Nutanix Solution. Could anyone help me?

I'm surprised how RDMA connect different memories through NIC without needing CPU. Memory is volatile storage and NIC is network I/O. they can't perform anything and can't understand application needs! 

I’m a newbie to Nutanix products and would like to understand more on the Nutanix web interface in regarding to the security standard. Is it unique session ID assigning to each session from the browser? Best regards, YLW

Hi TeamDoes Nutanix support IPV6 based VM deployments. Currently I am using Prism Central V3 API for deploying VM https://www.nutanix.dev/api_reference/apis/prism_v3.html#tag/vms/paths/~1vms/postIn the payload section it is mentioned that IPV4 support is only available now. If we want to do IPV6 based deployment, is there a workaround for that? Please share the document reference if IPV6 based VM deployment is not possible. If a workaround is there, please let me know how to do this. ThanksAkash

HiI am trying to install the community edition on three nodes and on each one it keeps on getting stuck on this screen I have tried multiple times and wait over 30 minutes any ideas? 

I have installed CE 2.0 on 3 Supermicro servers. AHV is up, and the CVM is running. The Genesis service is running on all 3 nodes. When I issue the command to create the cluster and use a comma separated list of IPs, I receive the following error (same error regardless of which CVM I run the command from):MainThread cluster:1001 Could not discover all nodes specified. Please make sure that the SVMs from which you wish to create the cluster are not already part of another cluster. Undiscovered ips : localhostThe localhost part is throwing me off. Any ideas? I can ping all the CVMs from all the other CVMs. I have restarted nodes, restarted genesis, and used the --skip_discovery with no luck. Any help would be appreciated. 

I’ve attempted to install a single node cluster (many times) and seem to have the same issues.  Post install, the cluster is not created.  Genesis appears to not be installed or running? I can ping and ssh between AHV and CVM.  Some issues I see leveraging the ‘troubleshooting common nutanix issues’: 

I’ve tried installing AHV/CVM and have ran into a multitude of issues.  However, I thought I finally got a successful CE up.  I was able to SSH to CVM, verify Genesis was running.  Yet I randomly get issues with this VM and the network and now, yet again, I can’t access the CVM or even the GW.  I’m following this doc: :https://www.jeroentielen.nl/installing-nutanix-community-edition-ce-on-vmware-workstation/.I’m also doing some troubleshooting from: https://portal.nutanix.com/page/documents/kbs/details?targetId=kA00e000000LM8BCAW and not getting anywhere.Sometimes I can ping the GW, sometimes I can SSH to the CVM, sometimes I can’t. 

Erasure coding is a data protection method that breaks data into pieces, adding redundancy for fault tolerance and data recovery. When we enabled RF2 on the cluster that copies data in two different nodes for fault tolerance, should I use erasure coding on the cluster? what is the benefit?

Hi While troubleshooting a performance issue with some VMs on the cluster, we noticed that the cluster-wide latency, as shown in the Prism graph on the front page, was around 23ms on average. This is significantly higher than our usual 10-12ms. Upon further investigation by support, the issue was traced to two VMs with high I/O activity, writing large blocks of data (over 1MB in size). To troubleshoot, we added the following graphs for each VM: Storage controller bandwidth (MB/s) Storage controller latency (ms) I have a few questions: Why is the term “bandwidth” used instead of “throughput”? My understanding is that bandwidth refers to the capacity (size of the pipe), while throughput is the amount of data passing through it per second. If the average cluster latency is high, wouldn’t this impact other workloads? Does the term “storage controller” refer to the CVM?Thanks in advance
