在运行以下脚本时，我在极少数情况下遇到错误。我编写了从 SCVMM 服务器获取数据并将其复制到 CSV 文件的脚本。该脚本每 15 分钟运行一次。我们已经使用我们的调度程序安排了这个。但这里的问题是，有时它会抛出警告，并且不会将所需的数据复制到 CSV 文件中。大多数时候它都在运行。在极少数情况下它会引发错误：

Get-SCCloud：VMM 无法连接到 VMM 管理服务器 calo-infvmm-01.calocosn.local，因为无法解析指定的计算机名称。

下面是我的脚本：

$VMMServer = "calo-infvmm-10001.calocosn.local"
$a = ((Get-Date).ToUniversalTime()).ToString("yyyyMMddTHHmmss")

$clouds = Get-SCCloud -VMMServer $VMMServer

$vmHeader = [string]::Concat("VMId",",","SubscriptionId",",","VMName",",","OperatingSystem",",","Memory(MB)",",","CPUCount",",","DiskUsed(GB)",",","DiskAllocated(GB)",",","StorageClassification",",","Owner",",","CreationTime",",","SampleTime",",","Status",",","StartAction",",","StopAction")
Write-Output $vmHeader

foreach ($cloud in $clouds) {
    $VMs = Get-SCVirtualMachine -Cloud $cloud
    foreach ($VM in $VMs) {
        $size = 0
        $maxSize = 0
        $classification = "Standard"
        foreach ($disk in $VM.VirtualHardDisks) {
            $classification = $disk.Classification
            $size += $disk.Size / 1gb

            $parentDisk = $disk.ParentDisk
            while ($parentDisk) {
                $size += $parentDisk.Size / 1gb
                $parentDisk = $parentDisk.ParentDisk
            }

            $maxSize += $disk.MaximumSize / 1gb
        }
        $vmText = [string]::Concat($vm.ID,",",$vm.UserRoleID,",",$vm.Name,",",$vm.OperatingSystem,",",$vm.Memory,",",$vm.CPUCount,",",$size,",",$maxSize,",",$classification,",",$vm.Owner,",",$vm.CreationTime,",",$a,",",$vm.Status,",",$vm.StartAction,",",$vm.StopAction)
