AHV GPU Series | Installing Nvidia grid virtual GPU manager

AHV supports GPU-accelerated computing for guest VMs. You can configure either GPU pass-through or a virtual GPU. Let us say you have an AHV host with GPU compatible hardware and looking for a simple way to install the required drivers. Nutanix recommends a specific method for installing the Nvidia GPU host driver in AHV hosts. The method involves a script which is used for installation or upgrade of all the hosts in the cluster. Go through the following document to understand the process in-depth Installing AHV GPU Drivers Have questions regarding the usage of the script? What will happen if one of the nodes doesn’t have a GPU? What will happen if the driver version is different on one node than the rest of the cluster? How can I install the driver onto the new nodes only, without affecting the currently running nodes? Can I install different versions of the driver onto different nodes of the cluster? The following knowledge base article can help you to

Warning - Hosts not connected to vCenter

Hi I’m new to nutanix with ESXi. I recently deployed a 4 nodes nutanix with esxi. I’ve created containers and add the nodes to the vCenter. I have not add the vCenter to the Prism. I check at prism and there’s a warning saying the hosts are not connected to vCenter. Anyone encounter this issue before?

Sizing SSD capacity to HDD capacity in a node

Just a quick question about sizing SSD capacity to HDD capacity in a node (in a new homogenous cluster). When specifying drive space in a node, what is the percentage SSD to HDD per node at a minimum. Is there a best practice guide that someone can point me towards? I’m not asking about the number of HDDs vs the number of SSDs.The question is around capacity and not number or drives. e.g. I configure a node with 4TB of SSD (2x1.92TB) and 60TB of HDD (10 x 6TB) and Nutanix Sizer says this is fine. This is roughly 6.25% SSD But what should I have as a minimum SSD capacity of of a hybrid node is 6% Okay, or should it be more like 10% or 20% (or more)?

Installing Nvidia host drivers before Cluster expand

We are in the Process of expanding our 4 Node Cluster to 6 Nodes. The Installation of the Hosts was successful using the Foundation VM. However, the servers have Nvidia cards installed, so we need to install the driver as well. When the Cluster is expanded with the 2 extra nodes, my understanding of the command “install_host_package” is, that it will install the drivers on all hosts, that have Nvidia cards. Even those, that already have the driver. To do so it will migrate the VMs and put the Hosts into maintenance. This is not an option for us, since the reason we are expanding the cluster is that the current cluster already is overloaded. I am looking for a way to install the drivers without interfering with the up and running environment. For example, is there a way to install the drivers before expanding the cluster?

Objects LCM Upgrades

Objects version upgrades by using LCM feature. You can perform LCM upgrades through Prism Central (PC). Objects is a part of the PC upgrades module in LCM. LCM upgrades the following components of Objects: Objects Manager and Objects Services.Objects ManagerObjects Manager is a containerized service running on a PC VM. The objects manager is primarily responsible for taking input from a user for deploying the object store, validating the user inputs, managing certificates, deploying the Objects Services and serves as an interface between PC and backing object store. A single Objects Manager can manage one or more object stores. In case of scale-out PC, the Objects Manager service runs on each of the PC nodes and provides high availability.During the upgrade of the Objects Manager, no disruption happens to the Objects IO. However, the user interface will not be available for a short period of time for statistics and management.Objects ServiceObjects Service provides the object store int

RE-IP and add VLAN to CVM and AHV

HI all, I'm preparing a change on the cluster (6 node cluster running AHV). I need to re-ip cvm's and ahv's and add them to a specific vlan (now they are not in a vlan). Before I do this in production I decided to do this on the test lab. (old baby, 4 node G5). I've followed this guide: https://next.nutanix.com/installation-configuration-23/physical-relocation-of-nutanix-clusters-38403 but got stuck step 7 after booting the cvm's. The ouput of svmips shows the old cvm ip's but they are all booted with the new ones. (and accessible via ssh on the new ip's)The output of hostips shows the old ahv ip's byt the are all booted with the new ones. (and accassible via ssh on the new ip's). I must also say that the external_ip_reconfig script hangs at a specific time and now the command “cluster start” gives an error the the cluster is still in reconfigure mode. Anyone here who has the golden tip to get the command svmips and hostips to show the correct ip's? (zk_server_config_file also had the

Password not accepted for SSH to CVM when cluster stopped?

We recently performed a cluster shutdown with hardware power off of an AHV cluster running AOS 5.15.5.1.We powered on all the nodes, and waited 10 minutes for the AHV hypervisor to boot and the CVMs to boot and get ready.Even after 30 minutes the CVMs did not recognise the confirmed correct password for the “nutanix” userID during ssh login attempt to any CVM.Fortunately one SSH key had previously been registered into Prism Element, which allowed SSH via this key. The cluster was NOT configured to be locked down.The key owner successfully connected to a CVM via SSH and performed sudo passwd set of the “nutanix” userID to a confirmed password.Despite setting this password, the same CVM still refused to accept the “nutanix” userID and confirmed correct password during SSH password login. I am suspecting that with the cluster service stopped, but with one SSH key present, that the CVMs operate as if lockdown were enabled.Can someone please confirm for this?This prevented the password hol

vCenter 7 vCLS HA/DRS cluster VMs questions

Hello, all. We’re running vCenter 7 with AOS 5.15.x, and I’m learning about how VMware has now decoupled the DRS/HA cluster availability from vCenter appliance and moved that into a three VM cluster (the vCLS VMs).In the interest of trying to update our graceful startup/shutdown documentation and code snippets/scripts, I’m trying to figure out how to handle these vCLS VMs. They reside on the Nutanix shared storage, so I obviously would like to shut them down before gracefully shutting down the Nutanix CVMs/ADSF cluster as well as ensure the CVMs are up and cluster is good before allowing them to power back on using that storage. Evidently, these vCLS VMs are very aggressive about powering back on or recreating themselves once deleted, so I’m a little unsure what to expect.So with regard to powering back on the ESX hosts, I assume when I take them back out of maintenance mode the CVMs will be powered back on (or maybe I have to do that manually?), and after waiting a few minutes, I woul

Nutanix Move: How to add second NIC to Move VM

Login to Prism Element Add New NIC to the Nutanix-Move appliance and select the network Launch the console of Nutanix Move appliance. Switch to root user Use vi editor or any other editor of your choice to open the file /etc/network/interfaces Add the second interface eth1 configuration in the format below based on DHCP/Static IP addressing. Restart the networking service.Please Note: If you are using Move 3.0.3 or above you can skip Step-7 and Step-8. That'll be taken care automatically. There will be an existing script named "start-xtract" under "/opt/xtract/bin". Overwrite that script with the one provided in the KB (see link below). Change the permissions for the script. Stop iptables and restart move services. Verify the new eth1 interface configuration using "ifconfig eth1". See KB7399 - Procedure to add a second NIC interface on Move v3.0.2 for detailed ins

Nutanix / VMware NSX / Cisco ACI

Hello Community, I have some doubts about running Nutanix on VMWare with ESXi with Cisco ACI fabric. To start, we have already married ourselves to a Cisco ACI network fabric (two sites connected with 12x10Gbit fiber (120Gbit)). We are using an IPN / Spine / Leaf topology, with APIC clusters in each site. In each DC there will be 24 Nutanix Nodes. All of my question have to do with the best practices of integrating these technologies. 1) Is it necessary to use VMware NSX to reap the benefits of Cisco ACI? 2) Can we just use a simple VMware installation (without NSX) and allow Nutanix full access to the ACI fabric? 3) Whats the best practices related to these three technologies coexisting together? I have found documents on Nutanix/ACI and Nutanix/VMWare, but I cant find anything on using all three together in terms of hierarchy and how to stitch it all together. Any guidance from those who have experience would be greatly appreciated. Thanks, Michael
