【问题描述】：
如何在与服务器不同的部署中创建 Azure SQL 故障转移组？
我们在部署中使用部署来实现并发部署。
我正在尝试创建 2 个 SQL Server，一个在英国西部（主要），一个在英国南部（次要），然后创建一个从主要到次要的故障转移组。
问题是在创建Failover组的时候，我必须引用主服务器来创建下的FOG。这是失败的，说 SQL Server 没有定义。
Deployment template validation failed: 'The resource 'Microsoft.Sql/servers/xxxxxx' is not defined in the template. Please see https://aka.ms/arm-template for usage details.'
是否可以将部署分开，但仍然创建引用 SQL Server 的 FOG？我能找到的所有示例都使用单个模板/部署，这使事情变得更加简单。

【问题讨论】：
-
不要使用
resourceId()函数，而是尝试使用concat()创建资源id，就像你使用databaseResourceId一样 -
我已经尝试过了，这只是将问题进一步推到故障转移组的名称属性上，该属性是服务器加上 FOG 名称的连接。
"name": "[concat(parameters('sourceSqlServerName'), '/', parameters('failoverGroupName'))]", -
去掉
concat()，只用"name": "[parameters('failoverGroupName')]" -
我会试一试，但我希望它只有嵌套在 SQL 服务器的模板中才能工作。
-
正如预期的那样，名称属性的段长度不正确。
Microsoft.Sql/servers/failoverGroups' at line '24' and column '5' has incorrect segment lengths.不幸的是，这个让我感到困惑！
