Question

如何添加我在门户中创建或从vmdepot导入到现有可用性集的现有VM？它似乎不可能来自门户网站，它是否在Powershell中运行？它是否适用于Resource Manager部署模型？

Answer 1

目前，对于ARM部署，尚不支持设置可用性集。可用性集只能在创建期间添加。因此，对于您的情况，您需要删除当前实例，并使用旧的OSDisk，Vnet和其他一些设置创建新部署。

这可以通过使用ARM模板来实现。以下示例说明如何使用现有VHD和Vnet部署VM。它还会创建新的可用性集，并将VM添加到可用性集中。

            }
          ]
        }
      }
    }
  ]
}

如果要将VM添加到现有可用性集，可以删除

    {
      "type": "Microsoft.Compute/availabilitySets",
      "name": "[parameters('availabilitySetName')]",
      "apiVersion": "2015-06-15",
      "location": "[parameters('location')]",
      "properties": {
        "platformFaultDomainCount": "3",
        "platformUpdateDomainCount": "20"
      }
    },

和

        "[concat('Microsoft.Compute/availabilitySets/', parameters('availabilitySetName'))]",

以上模板是从GitHub的this sample template修改的。

在我发布这个答案后，我一直在考虑使用REST API来更新带有可用性集的vm。我认为它可能有效，所以我试了一下，这是我得到的错误信息：

Invoke-RestMethod : {
  "error": {
    "code": "PropertyChangeNotAllowed",
    "target": "availabilitySet.id",
    "message": "Changing property 'availabilitySet.id' is not allowed."
  }
}
At C:\Users\v-dazen\Documents\setVMRestAPI.ps1:13 char:1
+ Invoke-RestMethod -Method Put -Uri "https://management.azure.com/subs ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-RestMethod], WebException
    + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand

这意味着无法为现有的ARM部署的VM设置可用性集。

从映像创建VM并添加到现有可用性集
