If unable to shutdown run the command $ sudo power off. Restart the VM. vm.guest_reboot vm_name enable_script_exec=[true or false] fail_on_script_failure=[true or false]Replace vm_name with the name of the VM. a. Connect with SSH to the CVM that is running on the node you want to bring down for maintenance. Exit Nutanix AHV host from Maintenance mode. Sorry, our virus scanner detected that this file isn't safe to download. Alert message: Main memory usage in Controller VM or Prism Central VM ip_address is high, available_memory_kb KB of memory is free. Sorry, our virus scanner detected that this file isn't safe to download. After a successful exit from maintenance mode, we now have a fully working member of a Nutanix AOS cluster and we can now migrate back VMs from other Nutanix AHV hosts. Ensure that you have met the following prerequisites before you initiate the power operations: NGT is enabled on the VM. Enter your username or e-mail address. Wait for the shutdown of the Nutanix AHV host to be successful, then ping the Nutanix AHV host to be sure that it is powered off. Alexander Ervik Johnsen NTNX-12AM2K470031-D-CVM running If the Controller VM is shut off, start it. If you have a Nutanix cluster on VMware vSphere which has been through some hypervisor upgrades, your CVM’s virtual hardware version may be a bit out of date. (IPMI is what we use here due to that the HW is Nutanix). Note : After we have successfully powered on the Nutanix AHV host, it will automatically power on the Nutanix CVM without any manual interference. May 14, 2020. and will not able to contact the service serving for the NCLI command. NGT version running on the Controller VM and user VM is the same. (AHV) I know 'acli vm.list power_state=on' returns a list of vms across the cluster.... and I know i can do an 'acli vm.force_off [VM Name]' to shut those down. To be sure that the CVM has shutdown, ping it, so you know that it is powered off or check Nutanix Prism that the CVM in focus is turned off. All operating systems that NGT supports are supported for this feature. CVM or Prism Central VM RAM Usage High [3023] [A1056] Name: CVM Memory Usage: Description: Check that CVM or Prism Central VM memory usage is not high. If a Nutanix AHV host is in maintenance mode then we need to exit it from maintenance mode to make it functional in the Nutanix Cluster again. The Nutanix CVM is hosted on the Nutanix AHV Hypervisor(in this case, it is the same with ESXi, Hyper-V and XenServer as well) as a VM and it´s responsible for running the Nutanix components and services in a Nutanix Cluster. Ensure there are no user VMs left on the host (only the CVM should be on there at this point). Step 2 : If Nutanix AHV host is member of Nutanix cluster then you need to enter Nutanix CVM / AHV host into maintenance mode , but first we need to live migrate the running VMs to another host in the Nutanix AHV Cluster. nutanix@cvm$ acli host.exit_maintenance_mode AHV-hypervisor-IP-address. Wait for the command to execute successfully. Hi All, I am trying to write a one (or few) liner to shutdown all non CVM vms found on the cluster. Sorry, we're still checking this file's contents to make sure it's safe to download. to abort the power operation if the pre-shutdown script fails. Note: The SSH session to the CVM must remain open for the iso to remain mounted on the IPMI. https://portal.nutanix.com/page/documents/details?targetId=AHV-Admin-Guide-v5_17:ahv-power-operations-vms-t.html. Note: Always use the cvm_shutdown command to power off, reset, or shutdown the Controller VM. Shutdown the CVM. Before we can shutdown the Nutanix AHV hypervisor we need to perform a graceful shutdown of the Nutanix CVM (Controller VM). The soft shutdown and restart operations are initiated and performed by Nutanix Guest Tools (NGT) within the VM thereby ensuring a safe and graceful shutdown or restart of the VM. Crafted in the land of the Vikings by Alexander Ervik Johnsen. It's a vSphere per-VM setting and I believe it is the recommended best practice.Out of curiosity, was the node in maintenance mode when you powered off. That´s it you have now learned how to Shutdown Nutanix CVM and Nutanix AHV Host. Step 1 : Log in to the Nutanix CVM with SSH. It's a vSphere per-VM setting and I believe it is the recommended best practice.Out of curiosity, was the node in maintenance mode when you powered off? NGT version running on the Controller VM and user VM is the one supported from AOS 5.6 or later. All of my CVM's are configured to power on with host, as the NFS datastore on the node with a powered off CVM will remain inaccessible until the CVM is powered up. Step 2 : Run the following command to exit the Nutanix AHV host from maintenance mode. Step 1 : To power on the Nutanix AHV host, need to press power button on Nutanix node or we can use the IPMI web console/iDrac/iLO etc. The soft shutdown and restart operations are initiated and performed by Nutanix Guest Tools (NGT) within the VM thereby ensuring a safe and graceful shutdown or restart of the VM. Shutdown the host. If the node is in maintenance mode, Log on to the CVM of this host and take the node out of the maintenance mode. The cvm_shutdown command notifies the cluster that the Controller VM is unavailable. Linux VMs: installed_dir/scripts/power_offNote that the file name of the script must be power_off. Run the following command in CLI to enter Nutanix AHV host into maintenance mode.

Note: This solution only works on SuperMicro hardware. root@ahv# virsh start cvm_name Replace cvm_name with the name of the Controller VM that you found from the preceding command. Windows VMs: installed_dir\scripts\power_off.batNote that the file name of the script must be, Linux VMs: installed_dir/scripts/power_offNote that the file name of the script must be, Soft shut down the VM. vm.guest_shutdown vm_name enable_script_exec=[true or false] fail_on_script_failure=[true or false], Restart the VM. vm.guest_reboot vm_name enable_script_exec=[true or false] fail_on_script_failure=[true or false], to run your pre-shutdown script and set the value of fail_on_script_failure to.
