Azure ARM (13) Create a new ARM VM from an existing VHD file

　　This article refers to the ARM Template of Git Hub:

　　https://github.com/Azure/azure-quickstart-templates/blob/master/201-vm-specialized-vhd-existing-vnet/azuredeploy.json

　　But the Template on Git Hub does not contain Availability Set

　　I modified this Template to set a high availability set:

　　https://github.com/leizhang1984/AzureChinaPowerShell/tree/master/ARM/VMSpecializedVHD

　　In many cases, we need to create a new ARM VM from the VHD file of the operating system disk of the Classic VM.

　　The key steps here are as follows:

　　1. Create a Classic VM and obtain the VHD path of the OS Disk

2. Create a new one 　　through ARM Portal:  https://portal.azure.cn

　　-　　Azure ARM Resource Group

　　-　　ARM Storage Account

　　-　　ARM Virtual Network和Subnet

　　3. If the Classic VM is powered on, use the AzCopy tool to copy the VHD files of the OS Disk and Data Disk to different containers in the same storage account (Classic Storage).

　　Then copy the VHD from Classic Storage Account to ARM Storage Account

　　4. If the Classic VM is powered off, use the AzCopy tool to copy the VHD files of the OS Disk and Data Disk to the ARM Storage Account.

　　5. Run Azure PowerShell to execute Template Deployment

　　Let's start this section

1. First , we create a new Azure Classic VM 　　in ASM mode ( https://manage.windowsazure.cn ). Steps omitted.

　　2. Check the OS Disk and Data Disk of this Classic VM, as shown in red in the following figure:

3. Create a new one 　　through ARM Portal:  https://portal.azure.cn

　　-　　Azure ARM Resource Group

　　-　　ARM Storage Account

　　-　　ARM Virtual Network和Subnet

　　4. To facilitate copying VHD, we shut down the virtual machine first. (Note that you must bind the fixed VIP and intranet DIP before shutting down)

　　5. Use the AzCopy tool to copy the VHD files of OS Disk and Data Disk to the ARM Storage Account.

　　6. After copying, we need to modify the corresponding ARM Template

　　7. azuredeploy.json in Git Hub, no need to modify

　　8. In azuredeploy.parameters.json in Git Hub, make the following changes:

{

    "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentParameters.json#",

    "contentVersion": "1.0.0.0",

    "parameters": {

        "dnsNameForPublicIP": {

            //Must be lowercase

            "value": "leiarmvmpublicip"

        },

        "existingVirtualNetworkName": {

            //Virtual network name, manually pre-selected and created

            "value": "LeiARMVNet"

        },

        "existingVirtualNetworkResourceGroup": {

            //In ARM mode, Resource Group name

            "value": "LeiARMRG"

        },

        "subnetName": {

            //In ARM mode, virtual network subnet name

            "value": "subnet-1"

        },

        "osDiskVhdUri": {

            //VHD file of the operating system

            "value": "https://leiarmstorage.blob.core.chinacloudapi.cn/vhds/LeiASMWeb01-LeiASMWeb01-2017-03-27.vhd"

        },

        "vmName": {

            //Virtual machine name

           "value": "LeiARMVMWeb01"

        },

        "osType": {

            //Operating system type

            "value": "Windows"

        },

        "vmSize": {

            //VM instance size

            "value": "Standard_D1_V2"

        },

        "diagStorageAccountName":{

            //Storage Account Name used by diag, must be lowercase

            //Can be the same as the Storage Account Name where osDiskVhdUri is located

             "value": "leiarmstoragediag"

        },

         "availabilitySetName":{

            //High availability set name

             "value": "Web-AvbSet"

        }

    }

}　

　　10. Run Azure PowerShell to verify:

#Login Azure China Cloud

Add-AzureRmAccount -EnvironmentName AzureChinaCloud;

# Select Azure China subscription ID

Select-AzureRmSubscription -SubscriptionID '[Subscription ID]'

#Execute Azure Deploy

New-AzureRmResourceGroupDeployment -Name ExampleDeployment -ResourceGroupName LeiARMRG -Mode Incremental -TemplateFile 'D:vmforuserimageazuredeploy.json' -TemplateParameterFile 'D:vmforuserimageazuredeploy.parameters.json'

　　11. After the execution is completed, the VHD file of the ARM Storage Account will be created in a new ARM VM. As follows:
