for eachとswitch条件でプリンシパル/ミラーの状態を処理する方法

Question

# Load SMO extension 
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo") | Out-Null; 

# Servers to check 
#$sqlservers = @("$svr", "$svr\$inst"); 
$sqlservers = Get-Content 'servers.txt' 
foreach ($server in $sqlservers) { 
    $srv = New-Object "Microsoft.SqlServer.Management.Smo.Server" $server; 
    # Get mirrored databases 
    $databases = $srv.Databases | Where-Object {$_.IsMirroringEnabled -eq $true}; 

    #Write-Host $databases; 
    Write-Host "=================================="; 
    # $test= $databases | Select-Object -Property Name, MirroringStatus | Format-Table -AutoSize; 
    $databases | Select-Object -Property MirroringStatus | Format-Table -AutoSize; 
    foreach ($status in $databases) { 
    switch ($databases.MirroringPartnerInstance) { 
     1 { $status. + "Disconnected" } 
     2 { $status. + "Suspended" } 
     2 { $status. + "Synchronizing" } 
     3 { $status. + "Not Synchronized" } 
    } 
    } 

このようなコードが必要です。

Below is my code if you do this way you will not get issue 

function mirroring (
[string] $svr, 
[string]$inst, 
[string] $datastore 
) 
{ 

Set-StrictMode -Version 2 
[Void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.ConnectionInfo") 
[Void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SMO") 
[Void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SmoExtended") 
$Conn = new-object Microsoft.SqlServer.Management.Common.ServerConnection 
$SqlConnection = "Server=$svr\$inst;Database=master;Integrated Security=True;" 
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand 
$SqlCmd.CommandText = " SELECT db_name(sd.[database_id])AS [Database Name] 
      ,sd.mirroring_state     AS [Mirror State] 
      ,sd.mirroring_state_desc    AS [Mirror State] 
      ,sd.mirroring_partner_name   AS [Partner Name] 
      ,sd.mirroring_role_desc    AS [Mirror Role] 
      ,sd.mirroring_safety_level_desc  AS [Safety Level] 
      ,sd.mirroring_witness_name   AS [Witness] 
      ,sd.mirroring_connection_timeout AS [Timeout(sec)] 
    FROM sys.database_mirroring AS sd 
    WHERE mirroring_guid IS NOT null 
    ORDER BY [Database Name];" 
$SqlCmd.Connection = $SqlConnection 
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter 
$SqlAdapter.SelectCommand = $SqlCmd 
$DataSet = New-Object System.Data.DataSet 
$SqlAdapter.Fill($DataSet) 
$DataSet.Tables[0] 
$datastore = $DataSet.Tables[0].Rows[0][2]    
write-host $datastore 

if($datastore -eq "Disconnected") 
{ 
# test 
DisconnectedREMEDIATION 

} 
elseif($datastore -eq "SYNCHRONIZED") 
{ 

SYNCHRONIZEDREMEDIATION 
} 



}
