Question

我正在寻找从许多服务器获取信息，即clustername，nodename和state。

当我将名称硬编码到这样的foreach循环中时，我可以获得正确的输出：

$clusters = "Cluster1", "Cluster2"
foreach ($cluster in $clusters) {
    Get-ClusterGroup -Cluster $cluster
}

但是当我运行这个从SQL表中提取信息的版本时，会出现以下错误。

$clusters = $SQLServer = "DatawarehouseServer" #use Server\Instance for named SQL instances!
$SQLDBName = "Datawarehouse"
$SqlQuery = "SELECT clusters FROM dbo.clusters"

$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server=$SQLServer;Database=$SQLDBName;Integrated Security=True"

$SqlCmd = New-Object System.Data.SqlClient.SqlCommand
$SqlCmd.CommandText = $SqlQuery
$SqlCmd.Connection = $SqlConnection

$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd

$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)

$SqlConnection.Close()

clear

$DataSet.Tables[0]

foreach ($cluster in $clusters) {
    Get-ClusterGroup -Cluster $cluster
}

我现在一直在尝试这一点，我似乎更接近一步，或者退一步看看你如何看待它。它现在可以提取正确的信息，但仅适用于一个群集：

感谢我的评论，我已经设法进一步或向后退一步：

$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server=Datawarehouseserver;Database=Datawarehouse;Integrated Security=True"
$SqlConnection.Open()
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand
$SqlCmd.CommandText = "SELECT clusters FROM dbo.clusters"
$SqlCmd.Connection = $SqlConnection
$clustername = $SqlCmd.ExecuteScalar()
$SqlConnection.Close()
#Write-Output "Cluster is " $dbname
clear
foreach ($cluster in $clustername) {
    Get-ClusterGroup -Cluster $cluster
}

您需要迭代SQL查询返回的群集名称，但永远不会为您的变量$cluster分配名称列表。请改用：

foreach ($cluster in $DataSet.Tables[0].clusters) {
  ...
}

使用导入的SQL表
