5 Essential Tips for Maximizing Your Experience at Nutanix .NEXT for Bloggers
Hi Eric, This is most likely a false-positive alert from your NCC version, we are aware of this issue and have seen it in NCC-3.8.0 & NCC-3.9.4, the fix was implemented in NCC-3.10.1. You can verify that it’s false positive simply by seeing the same name in the CVM shell or in Prism as it was previously. However, it’s recommended that you open a case with Nutanix to verify this.
Hi Florian, Please ssh to a CVM to obtain the IP address of the uhura leader CVM: links http://localhost:2037 --dump | grep -i "Uhura Master" SSH to the IP address received from the command above and check the “data/logs/uhura.out” file, search for the timestamp of the error and look for this message: “Unexpected error happened: vCenter connection could not be established” This occurs when vCenter connection could not be established by Nutanix Files if the hypervisor is ESXi. If this is the issue, then run: genesis stop uhura ; cluster start If the issue was not solved after this, consider contacting Nutanix support and we will check the logs to understand the root cause.
I’m glad I could help! I’m not aware of an exact date but I’m sure it won’t take long for the NCC-3.10.1 to be released
Hi Hienle, The expansion process shouldn't be much different with Hyper-v, the instruction to expand a cluster is the same although you can see some notes that are made specifically for hyper-v which makes the small difference. For example: If the cluster is running Hyper-v, you must first configure the nodes in the VLAN before attempting to add them. Otherwise, the discovery process will not find these nodes. See the "Configuring the Cluster in a VLAN-Segmented Network" section in the Acropolis Advanced Setup Guide for VLAN configuration instructions. If you want to move the VMs between hyper-v nodes, ensure that you have selected the Migrate to a physical computer with a different processor version option for each VM by navigating to Settings > Processor > Compatibility in the Action pane of the Hyper-V Manager. [Hyper-V only] Specify the credentials to join the new nodes to Active Directory and to a failover cluster. Here is the full documentation for cluster expansion via t
Hello, There is no special log file from Nutanix that logs the cmods and the directory modifications. I’m not sure if there is another generic way beside checking the shell history and the .bash_history files.
Hi Mark, The CVM is most likely still in maintenance mode and maybe the host as well. to check if the CVM is in maintenance run this on any other CVM “ncli host list” You will see the hosts (the CVMs) and if it’s in maintenance mode. If you want to check if the host itself is in maintenance you can run “acli host.list” It’s also very simple to pull a CVM/host out of maintenance mode: https://portal.nutanix.com/kb/4639
Hello, If you connect to the CVM of host NTNX-3/AHV and run “ncli vm list”, can you see the VM? If yes then the VM is still on the AHV If you deleted it from the cli there is a chance that prism was not updated. You can find the prism leader by running this on any CVM: curl localhost:2019/prism/leader && echo and then SSH to the IP received from the command above (to the prism leader CVM) and run: allssh cluster stop prism; cluster start If after this you still see the VM in Prism but not in AHV, consider opening a case with us through the portal or give us a call, the deletion task could be stuck and might need cancellation.
Hello, Are you running a Dell R640 node? This is expected behavior on these nodes when running NCC 3.5.x due to a driver limitation preventing the 'cpupower' data from being collected by NCC. If that’s the case then you can upgrade NCC or disable this specific check: Go to Prism Health tab Search for Host CPU Frequency Check Go to the check and Select Turn Check Off You can check out KB-5542 for more information about this check on all hardware.
Hello, In general, it’s not possible to expand a single or two nodes cluster, you will have to destroy and create a new cluster from the 3 nodes (assuming that you already have our AOS on the 3 nodes), after that the expansion will be easy following a few steps in Prism. The single-node and two-node solutions are supported on the NX-1175S-G5 and NX-1175S-G6 only. Check out this KB for more information about Single-Node and Two-Node cluster: KB-5943 Let me know if you have any question.
Hi Cory, To grant a service account an admin permissions, go to Prism > Home (drop-down menu) > File server > Click on the name of the Server and then click “Manage roles”. You can edit the credential of each user and grant it “File Server Admin: Full Access”.
Hello, I advice you to contact Nutanix Sales since the Engineers on this platform and on the other side of the support line are focused on the technical part of Nutanix products and can’t provide accurate numbers when it comes to pricing, this is mainly because the prices are affected by several factors such as your block model and it’s compatibility with the different components (there are several memory, satadoms and drives types). If you want to do the calculation yourself check out this page where we specify for each model which components are supported.
Hi Shanmugavadivel, You can’t and must not delete the admin account, I understand that the admin user can be a potential security risk however the account is a built-in user that can’t be deleted nor disabled since it has a critical part of administrating the cluster. The best practice is to set a complicated password for the account and give it only to authorized people in your organization.
Hi @Jose_orozco You will have to install VirtIO for windows VMs on AHV, you can download the latest version from here. after downloading it, upload it to your cluster via Prism. When the VirtIO image is in your cluster, go to the VM list > double click on the windows VM in Prism, add a disk with this configuration: Type = CD-ROM Operation = Clone from Image Service Bus Type = IDE Image = attach the VirtIO image that you downloaded earlier. Click on Add Check out this page for more information and instructions: https://portal.nutanix.com/#/page/docs/details?targetId=AMF-Guide-AOS-v50:vmm-vm-virtio-ahv-c.html
