失败时暂停，重试 CSV 输入

Question

我有 2 段 PowerShell 代码在失败时退出脚本。在考虑之后，我意识到在出现故障时暂停并让管理员有时间进行补救会更有意义......然后当任何键暂停时，重试 CSV 中的同一行。现在是这样的：

#check tools status first
Write-Host ""
Write-Host "Checking VMware Tools Status before proceeding." -foreground green
Write-Host ""
foreach ($item in $vmlist) {
    $vmname = $item.vmname
    $ToolsStatus = (Get-VM $vmname).extensiondata.Guest.ToolsStatus -eq "toolsNotRunning"
    if ($ToolsStatus -eq $true) {
        Write-Host ""
        Write-Host "Tools is not installed or running on $vmname. Remediate on guest and restart the script" -foreground Yellow
        Write-Host "Script will continue to exit until tools is running on $vmname" -foreground yellow
        Write-Host ""
        exit
    } else {
        Write-Host ""
        Write-Host "Tools running on all VMs, script will continue" -foreground green
        Write-Host ""
    }
}

我知道如何在 $Host.UI.RawUI.ReadKey('NoEcho,IncludeKeyDown') 中暂停，但我不知道如何进行循环，所以它会重试。

我在别处使用类似的代码来验证 VM 是否已启动，因此这在两个部分都有效。

编辑：这是重新编写的脚本。这行得通吗？

foreach ($item in $vmlist) {
    $vmname = $item.vmname
    do {
        $ToolsStatus = (Get-VM $vmname).extensiondata.Guest.ToolsStatus -eq "toolsNotRunning"
        if ($ToolsStatus) {
            Write-Host ""
            Write-Host "Tools is not installed or running on $vmname." -Foreground yellow
            Write-Host "Remediate VMware tools on $vmname and"
            Write-host "Press any key to retry..."
            $Host.UI.RawUI.ReadKey('NoEcho,IncludeKeyDown')
        }
    } until ($ToolsStatus -eq "PoweredOn")
    Write-Host "Tools running on $vmname, script will continue" -Foreground green
}

像这样添加一个嵌套的 do..while 循环：

foreach ($item in $vmlist) {
    $vmname = $item.vmname
    do {
        $ToolsMissing = (Get-VM $vmname).extensiondata.Guest.ToolsStatus -eq "toolsNotRunning"
        if ($ToolsMissing) {
            Write-Host "Tools is not installed or ..." -Foreground yellow
            $Host.UI.RawUI.ReadKey('NoEcho,IncludeKeyDown')
        }
    } while ($ToolsMissing)
}

Write-Host "Tools running on all VMs, script will continue" -Foreground green
