一個簡單的powershell腳本來恢復vSphere狀態

Question

我對powershell + powercli非常陌生，並且需要一隻手。

我們有3/4個主機連接到vCenter實例，我們想要運行PowerShell腳本來識別哪些虛擬機正在運行，將名稱記錄到文件中，暫停（或關閉）計算機。

下一次腳本運行時，它會讀取名稱列表並打開相關VM的電源......在PowerCLI/Powershell環境中執行此操作的最簡單方法是什麼？

我在想流媒體/作家，但似乎令人費解！

Answer 1

考慮使用Join-Path，Set-Content和Add-Conent更多的PowerShell的方式。像這樣，

# Combine $filepath and MTS_ON.txt, adds slashes if need be 
$pfile = join-path $filePath "MTS_ON.txt" 
# Create empty file or truncate existing one 
set-content -path $pfile -value $([String]::Empty) 

foreach($objHost in $ESXHost) { 
    $PoweredVMs += Get-VMHost -Name $objHost | Get-VM | where {$_.Powerstate -eq "PoweredON" } 
    foreach($objVM in $PoweredVMs) { 
     add-content -path $pfile -value $objVM 
     Get-VM -Name $objVM | Suspend-VM 
    } 
} # No need to close the pfile

這似乎是個伎倆！有什麼建議麼？

#File Storage Path 
$filePath = "D:\" 

#Get the host lists and sort 
$ESXHost= Get-VMHost | Sort-Object -Property Name 

function storeEnvironment 
{#Store the powered VM list to a simple file 
    #Use Streamwriter for simpler output, just a string name 
    $PowerFile = New-Object System.IO.StreamWriter($filePath+"MTS_ON.txt") 

    foreach($objHost in $ESXHost) 
    { 
     $PoweredVMs += Get-VMHost -Name $objHost | Get-VM | where {$_.Powerstate -eq "PoweredON" } 
     foreach($objVM in $PoweredVMs) 
     { 
      $PowerFile.WriteLine($objVM) 
      Get-VM -Name $objVM | Suspend-VM 
     } 
    } 
    $PowerFile.close() 
} 

function restoreEnvironment 
{ 
    [array] $VMs = Get-Content -Path $filePath"MTS_ON.txt" 
    foreach($VM in $VMs) 
    { 
     Get-VM -Name $VM | Start-VM 
    } 
    #Delete the configuration file 
    Remove-Item $filePath"MTS_ON.txt" 
} 

#MAIN 

#Test to see if the config file exists 
if(Test-Path $filePath"MTS_ON.txt") 
{ 
    Write-Host "Restore from file? [Y]es or [N]o" 
    $response = Read-Host 
    if($response -eq "Y") 
    { 
     #Use file to restore VMs 
     Write-Host "Restore Environment" 
     restoreEnvironment 
    } 
    else 
    { 
     #Delete the configuration file 
     Remove-Item $filePath"MTS_ON.txt" 
    } 
} 
else 
{#Save the powered VMs to a file 
    Write-Host "Saving Environment" 
    storeEnvironment 
}
