AppService VNET集成失败，VNET已被占用

Question

我有一个较旧版本的appservice Plan，它连接到VNET/Subnet。当我想把它升级到VNET集成时，appservice计划被完全删除了。但是，当我尝试使用相同的VNET/Subnet重新部署App服务计划时，会失败，并显示以下错误。

Status Message: {
 "Code": "Conflict",
 "Message": "Subnet xxx-subnet in VNET xxx-vnet is already occupied by service ***/providers/Microsoft.Web/serverfarms/shared.",
 "Target": null,
 "Details": [
 {
 "Message": "Subnet xxx-subnet in VNET xxx-vet is already occupied by service ***/providers/Microsoft.Web/serverfarms/shared."
 },
 {
 "Code": "Conflict"
 },
 {
 "ErrorEntity": {
 "ExtendedCode": "55914",
 "MessageTemplate": "Subnet {0} in VNET {1} is already occupied by service {2}.",
 "Parameters": [
 "xxxx-subnet",
 "xxxx-t-vnet",
 "***/providers/Microsoft.Web/serverfarms/shared"
 ],
 "Code": "Conflict",
 "Message": "xxxx-subnet in VNET xxxx-t-vnet is already occupied by service ***/providers/Microsoft.Web/serverfarms/shared."
 }
 }
 ],
 "Innererror": null
} (Code:DeploymentOperationFailed)```


Not sure how we can proceed here as cannot find the older app service plan in Portal as well.

Answer 1

查看讨论，看起来子网上设置了serviceAssociationLink属性。当应用程序服务计划中的第一个Microsoft.Web应用程序与子网集成时，此属性由集成子网上的Web资源提供程序初始化。

您可以通过查看此属性

查看该属性下的link属性，您将看到它将具有对App Service Plan的引用。这是我的截图。

您可以使用Azure support记录支持票证，他们可以帮助您清除该子网上的ServiceAssociationLink。

Answer 2

在您也在部署App服务的子网上，您是否可以尝试将"Subnet Delegation“更改为"None”。

这样，子网不是专用于特定服务的，那么任何东西都应该连接到它。然后，您可以尝试将“子网委派”重新添加回“Microsoft.Web/serverfarm”。
