Redeploy Linux virtual machine to new Azure node

  • Article

If you face difficulties troubleshooting SSH or application access to a Linux virtual machine (VM) in Azure, redeploying the VM may help. When you redeploy a VM, it moves the VM to a new node within the Azure infrastructure and then powers it back on. All your configuration options and associated resources are retained. This article shows you how to redeploy a VM using Azure CLI or the Azure portal.

Warning

After you redeploy a VM, all the data that you saved on the temporary disk and Ephemeral disk is lost. The dynamic IP addresses associated with virtual network interface are updated.

Use the Azure CLI

Install the latest Azure CLI and log in to your Azure account using az login.

Redeploy your VM with az vm redeploy. The following example redeploys the VM named myVM in the resource group named myResourceGroup:

az vm redeploy --resource-group myResourceGroup --name myVM

Use the Azure classic CLI

Important

Classic VMs will be retired on September 1, 2023

If you use IaaS resources from ASM, please complete your migration by September 1, 2023. We encourage you to make the switch sooner to take advantage of the many feature enhancements in Azure Resource Manager.

For more information, see Migrate your IaaS resources to Azure Resource Manager by September 1, 2023.

Install the latest Azure classic CLI and log in to your Azure account. Make sure that you are in Resource Manager mode (azure config mode arm).

The following example redeploys the VM named myVM in the resource group named myResourceGroup:

azure vm redeploy --resource-group myResourceGroup --vm-name myVM

Use the Azure portal

  1. Go to the Azure portal, select the VM you wish to redeploy.
  2. In the Help section, select Redeploy + reapply, and then select Redeploy to migrate it to a new Azure host.

The image shows the redeploy and reapply option.
