Hello I am looking for guidance regarding setting up a 3-node and 2 node AHV cluster on 1G switches . Our workloads are low. The official response is to use a 10G switch fabric. If I opt for 2 node, can I connect the servers back to back for distributed storage ? Can data network go over 1G ? I plan to procure 2 servers with 2x 10G for distributed storage , 2x 1G NICs for data Thanks,Ajay
We tried to create a create a new user in Prism with reference to article: Managing Local User Accounts | Nutanix CommunityWe created the new user successfully, but unable to login using the new user. Getting error: Incorrect username or password error.We have even reset the password several times, also deleted the user and created another still we are getting same error.Please help us with any solution.
Hello Nutanix Community,We are running Nutanix HCI on Lenovo servers having three-node cluster & currently the cluster has less capacity. We have 2 empty HDD slots on each Lenovo serves and we are planning to insert same capacity HDD drives on all 3 servers. So totally 6 HDD with a capacity of 2.4TB each.I would like to know how to configure and expand the storage? Please note that I’m new to Nutanix so kindly help me from scratch:-)Thanks in advance to everyone.
I want to install prism central on my cluster, I started downloading the software from my prism element.For more than 48 hours the download is still in progress and I want to abort the download process and resume the installation but I don't see any button allowing me to do this.Can you give me the process to abort the central prism download please?
Hi,we added additional networkcards into the servers, but when doing a ifconfig -a | less the additional cards/ports are not being displayed.Also the CVM starts and goes into a continous boot loop. the following is being displayed UNLOAD: attempting modprobe remove virtio-pciNow our question is why are the additional ports not being displayed? Are drivers needed in order for the CVM to boot correctly with the new card installed? Thanks
DearsPlease your support in this critical case : I have 2 nutanix blocks, each 3 nodes;they`re all connected to a one switch with 12 cables ( 2 each), all in the same vlan (vlan 1), the switch is connected to firewall (trunk port from switch to firewall), I had set the cvm ip to 10.10.20.x range, I have the gateway from firewall 10.10.20.254, how I can add gateway to the cluster so the vms inside can be reached?what network settings or changes I must do? Thank you
Hi,I`ve replaced the SATADOM of one of the four hosts in my NX-1050. After starting from the pnoenix.iso, the repair host disk has been stuck like this for 24 hours. The host_bootdisk_repair_status says it`s at “sm_trigger_imaging” state.The first thing I would like to do is kill the current repair job since it`s most certainly hanging. How can I do that and what further steps should I take to try and get the host back online? Thank you.
hi community,we want to expand the cluster by adding additional node, the server model is HPE ProLiant DX360 , currently 4 nodes are running and we want to add one node of same hardware model. the hardware is factory AOS imaged. AHV is the hypervisor on current cluster.we want to know what are the physical network connectivity is required to add the node and image AHV.on new node IPMI is connected and two 10g are connected , but we are unable to discover the node from prism element. is it required to connect the node port 1g as well to the switch for imaging?
I have a few NX G8 nodes I want to install and configure, however the ToR Switches currently available are 1G switches (I have ordered 10G switches but they are late). I have a few questionsIn the pink circle above, the left port is Shared IPMI (10G) and the right one is its failover (as I’ve seen in NX Hardware specifications), however the speed for Failover port is not specified. Does any one know whether it’s 10G or 1G? And it is activated by default or should I go into BIOS Setup and activate the port during boot? My idea is to use this Failover port for Nutanix imaging and subsequently use it for CVM, Host and User VM traffic (temporarily). Has anyone tried this before? Any issues during Foundation imaging? I’m aware there will be performance issues when it comes to AHV/CVM services running as well as VM performance. Thanks everyone in advance!
Hello,Does anybody know where I can find the 'Nutanix AHV Best Practices', as found in the google search below, I can't for the life of me find it.Specially looking for best practices for different workloads, and that article based on the description seemed to hit the nail on the head regarding higher clock speeds for database workloads for example.i find that a lot of Google links just end up with a "Not Found or Forbidden" message.

I have figured out that the version of the kernel is 4.19.100. I have also figured out that this version is not working with my NUC11 and the i225-V NIC. I would like to replace that kernel with the 5.15 kernel as the 5.15 kernel works with the i225-V NIC. Does anyone have a procedure on how to replace the kernel in the ISO? Any help would be greatly appreciated. Thanks,Steve
Ladies/Gents,Second time this happens. First time it did, I did not know how to fix this and did a reinstall. This time I am trying to find a way to avoid going down the full reinstall route…The issueAfter a power failure, in my area, the power may come back for like 5-60 seconds and then off again. This may happen once or twice after the power failure. In that case, what happens, is the AHV seems to mark the two NVMe drives as not available (I have one SSD, 120GB Western Digital booting AHV - so boot drive, and two Samsung EVO 1TB) and due to that, CVM and all VMs are gone.Booting off a USB stick with Linux Mint we can see the drives listed: All I can find is info that requires the CVM, what is gone in this case…So how can this be fixed? Is it a matter of booting with the Nutanix CE USB and doing a repair? Is there something that can be done on AHV (what of course I do have access to) that will 'unflag' the disks as bad (what they are not - if I do reinstall the whole thing and start
This one may be an obvious question, but its probably too obvious to the point that I am overthinking it.Model: NX-6035-G4I came into an environment where there are 5 clusters. Each clusters. Each one has both NIC’s on each node connected directly to the core switch. Each specifying the VLAN access on the core switch.Now the SFP ports are running DAC cables to a 10 Gig switch that is just in trunk mode. That switch then Trunks to the core switch.So are you suppose to use both? I thought you only had to use one or the other, normally this doesn't matter, but the Core switch is over saturated and I could close out 10 Unnecessary wires.I drew a diagram encase this was wordy.
