We have to shut down one of our Nutanix devices to replace a faulty fan. Please try again in a few minutes. Step 3 : Now to proceed to shutdown the Nutanix CVM. Do NOT delete the Nutanix Controller VM on any Nutanix host (CVM names look like: NTNX---CVM) Do NOT modify any settings of a Controller VM, all the way down to even the name of the VM. If you are using Nutanix HCI with VMware vSphere ESXi hypervisor and want to manually stop / start / shutdown the Nutanix vSphere cluster / ESXi host / ESXi node with Best practice. Step 2 : If Nutanix AHV host is member of Nutanix acropolis cluster then you need to enter Nutanix CVM / AHV host into maintenance mode first to live migrate the running VMs to another running host(s) in the Nutanix AHV cluster. Hello, thank you for this interresting post. If you have a support contract, I would suggest logging into the support portal and review the vSphere Admin Guide (link below). In the Confirm Maintenance Mode, click OK.The host gets ready to go into maintenance mode, which prevents VMs from running on this host. To run following command to enter Nutanix AHV host into maintenance mode, To run following command to enter Hyper-V host into maintenance mode. To Exit Nutanix AHV host from maintenance mode need to run following command from Nutanix CVM, Step 2 : Run command following command to to exit host from maintenance mode. Note: Always use the cvm_shutdown command to power off, reset, or shutdown the Controller VM. If you are using Nutanix HCI with VMware vSphere ESXi hypervisor and want to, https://portal.nutanix.com/#/page/docs/details?targetId=vSphere-Admin6-AOS-v51:vSphere-Admin6-AOS-v51, Shutting Down a Node in a Cluster (vSphere Web Client), Shutting Down a Node in a Cluster (vSphere command line), Shutdown / Start Nutanix vSphere Cluster – Best Practice. Run the command “cluster stop” to bring down the Nutanix Cluster. We'll send you an e-mail with instructions to reset your password. If successful, this command returns no output. Hi, nope, the CVM musn't be migrated when putting the ESXi in maintenance mode. Kinda, but after you move the VM's off, to properly shut down a single CVM, you should log into the CVM and use the command cvm_shutdown first, which gracefully stops all the services on that system, then you can put the underlying vsphere host into maintenance mode. To validate Nutanix CVM shutdown status, ping the Nutanix CVM ip address. Shutdown/Startup gotchas: It’s probably best to never shutdown/reboot/etc. can we ignore the point as these VMs will be migrated while putting the ESXi host in maintannace. Log on to the Controller VM with SSH and shut down the Controller VM. To increase the cache size on Nutanix you simply need to power off the controller virtual machine (CVM) on a host, increase RAM, and power it back on. I would like to do the maintanance for all the host one by one so that I can complete the Maintannance with out downtime for VM. Verify if the parameter Under Maintenance Mode is set to False for the node where the services are down. Enter your username or e-mail address. Log in or register now! Step 3: Now to proceed to shutdown the Nutanix CVM. If unable to shutdown run the command $ sudo power off. Replace hypervisor_ip_addr with the IP address of the ESXi host. After Exit Nutanix AHV host from maintenance mode, will be a working / functional member of Nutanix acropolis cluster and will take back the it own VMs back from other Nutanix AHV hosts. Read complete step step to Shutdown / Start Nutanix vSphere Cluster – Best Practice. nutanix@cvm$ cvm_shutdown -P now. nutanix@cvm$ ping hypervisor_ip_addr Replace hypervisor_ip_addr with the IP address of the ESXi host. Steps to shutdown the Nutanix Cluster: Ensure that the “Data resiliency” status of the target cluster is normal and there is no active critical alerts present. Log on to vCenter Server by using vSphere Web Client. nutanix@cvm$ ping hypervisor_ip_addr My assumption is to first migrate all VMs to different hosts, then shut down the CVM, put the host in "matainence mode", then shut down the Host. Shutdown CVM by ssh'ing or console and issuing "sudo shutdown -h now" command.3) do what you need to do to host4) Reboot host5) ensure CVM restarts and cluster returns to healthy status. Hi All, I am trying to write a one (or few) liner to shutdown all non CVM vms found on the cluster. Wait to execute the command successfully. To shutdown or power off the Nutanix Acropolis Hypevisor AHV and Nutanix Controller VM ( CVM ) in Nutanix cluster or Non Nutanix cluster have right procedure to shutdown properly without any harmful impact on running services and software in Nutanix AHV Hypervisor as well as Nutanix CVM. Best answer by GPVenkatesh 13 April 2017, 16:17. Sorry, we're still checking this file's contents to make sure it's safe to download. Step 4 : Log in to Nutanix AHV host thru SSH, Step 5 : Shutdown or power off the Nutanix AHV host. Alternatively, you can put the ESXi host into maintenance mode and shut it down using the vSphere Web Client. Right-click the host and select Shut Down.Wait until vCenter Server displays that the host is not responding, which may take several minutes. Every time we do maintenance on an ESXi host, we put the host into maintenance mode and shut down the CVM. I'm curious, what is the purpose of putting the CVM into maintenance mode as opposed to just shutting it down? Arrêter la CVM Nutanix proprement / Cvm_shutdown Lorsque vous éteignez une CVM pour maintenance ou lorsque vous la rebooter et que vous utiliser les commandes classiques sudo shutdown ou sudo reboot, les IOs des VMs “hébergées” par la CVM sont redirigés violemment sur les autres CVM du cluster. DRS automatically attempts to migrate all the VMs to another host in the cluster. The cvm_shutdown command notifies the cluster that the Controller VM is unavailable. nutanix@cvm$ ~/serviceability/bin/esx-enter-maintenance-mode -s cvm_ip_addr Gracefully shutdown each CVM at this point: from the shell that you opened previously type “cvm_shutdown -P now” Shutdown all CVMs like this; Finally shutdown the hosts. Run the command $ cvm_shutdown -P now. If Nutanix AHV host in maintenance mode then you need to exit from maintenance mode to make it functional in Nutanix acropolis cluster.
