Question

您好我尝试创建一个PS脚本来分配驱动器号，格式化并标记驱动器所需的分配单元大小。

CSV文件（Storage_Data_Input.txt）类似于：

DiskNumber,DriveLetter,NewFileSystemLabel,AllocationUnitSize
7,N,Drive_N,4096
7,N,Drive_N,4096

脚本是这样的：

########################
# New Partition/Drive letter/Format/Label/Allocation
Measure-Command{ 

Clear


$Datalist = Import-Csv "H:\My Documents\My Powershell\Storage_Data_Input.txt"
$ServerList = Get-Content "H:\My Documents\My Powershell\serverlist.txt"

ForEach ($Item in $Datalist){
$DiskNumber=$($Item.DiskNumber)
$driveletter=$($Item.DriveLetter)
$NewFileSystemLabel=$($Item.NewFileSystemLabel)
$AllocationUnitSize=$($Item.AllocationUnitSize)


$c=Get-Credential Domain\Userid 

foreach ($ServerName in $ServerList){
Write-Host "Setting Drive_"$DriveLetter" on server "$ServerName""
Invoke-Command -ComputerName $ServerName -Credential $c -ScriptBlock {

Stop-Service -Name ShellHWDetection

New-Partition -DiskNumber "$DiskNumber" -UseMaximumSize -DriveLetter "$driveletter" | Format-Volume -FileSystem NTFS -NewFileSystemLabel "$NewFileSystemLabel" -AllocationUnitSize "$AllocationUnitSize" -Force -Confirm:$false

Start-Service -Name ShellHWDetection 

}}}}

执行时获得以下错误：

Cannot process argument transformation on parameter 'DriveLetter'. Cannot convert value "" to type "System.Char". Error: "String must be exactly one character long."
+ CategoryInfo          : InvalidData: (:) [New-Partition], ParameterBindin...mationException
+ FullyQualifiedErrorId : ParameterArgumentTransformationError,New-Partition
+ PSComputerName        : Servername

如果您正在执行远程变量，则必须作为参数列表传递或使用“使用”提供程序引用。

e.g。

Invoke-Command -ComputerName $ServerName -Credential $c -ScriptBlock {
    Stop-Service -Name ShellHWDetection
    New-Partition -DiskNumber "$using:DiskNumber" -UseMaximumSize -DriveLetter "$using:driveletter" | Format-Volume -FileSystem NTFS -NewFileSystemLabel "$using:NewFileSystemLabel" -AllocationUnitSize "$using:AllocationUnitSize" -Force -Confirm:$false
    Start-Service -Name ShellHWDetection 
}

无法转换价值＆＃34;＆＃34;输入＆＃34; System.Char＆＃34;
