将 Amazon EC2 Windows 实例上的 NVMe 磁盘映射到卷

以下 PowerShell 脚本列出每个磁盘以及相应的设备名称和卷。旨在与基于 Nitro 的实例结合使用，此类实例使用 NVMe EBS 和实例存储卷。

连接到 Windows 实例并运行以下命令以启用 PowerShell 脚本执行。

Set-ExecutionPolicy RemoteSigned

复制以下脚本并将其保存为 Windows 实例 mapping.ps1 上。

# List the disks for NVMe volumes

function Get-EC2InstanceMetadata {
    param([string]$Path)
    (Invoke-WebRequest -Uri "http://169.254.169.254/latest/$Path").Content 
}

function GetEBSVolumeId {
    param($Path)
    $SerialNumber = (Get-Disk -Path $Path).SerialNumber
    if($SerialNumber -clike 'vol*'){
        $EbsVolumeId = $SerialNumber.Substring(0,20).Replace("vol","vol-")
    }
    else {
       $EbsVolumeId = $SerialNumber.Substring(0,20).Replace("AWS","AWS-")
    }
    return $EbsVolumeId
}

function GetDeviceName{
    param($EbsVolumeId)
    if($EbsVolumeId -clike 'vol*'){
    
        $Device  = ((Get-EC2Volume -VolumeId $EbsVolumeId ).Attachment).Device
        $VolumeName = ""
    }
     else {
        $Device = "Ephemeral"
        $VolumeName = "Temporary Storage"
    }
    Return $Device,$VolumeName
}

function GetDriveLetter{
    param($Path)
    $DiskNumber =  (Get-Disk -Path $Path).Number
    if($DiskNumber -eq 0){
        $VirtualDevice = "root"
        $DriveLetter = "C"
        $PartitionNumber = (Get-Partition -DriveLetter C).PartitionNumber
    }
    else
    {
        $VirtualDevice = "N/A"
        $DriveLetter = (Get-Partition -DiskNumber $DiskNumber).DriveLetter
        if(!$DriveLetter)
        {
            $DriveLetter = ((Get-Partition -DiskId $Path).AccessPaths).Split(",")[0]
        } 
        $PartitionNumber = (Get-Partition -DiskId $Path).PartitionNumber   
    }
    
    return $DriveLetter,$VirtualDevice,$PartitionNumber

}

$Report = @()
foreach($Path in (Get-Disk).Path)
{
    $Disk_ID = ( Get-Partition -DiskId $Path).DiskId
    $Disk = ( Get-Disk -Path $Path).Number
    $EbsVolumeId  = GetEBSVolumeId($Path)
    $Size =(Get-Disk -Path $Path).Size
    $DriveLetter,$VirtualDevice, $Partition = (GetDriveLetter($Path))
    $Device,$VolumeName = GetDeviceName($EbsVolumeId)
    $Disk = New-Object PSObject -Property @{
      Disk          = $Disk
      Partitions    = $Partition
      DriveLetter   = $DriveLetter
      EbsVolumeId   = $EbsVolumeId 
      Device        = $Device 
      VirtualDevice = $VirtualDevice 
      VolumeName= $VolumeName
    }
	$Report += $Disk
} 

$Report | Sort-Object Disk | Format-Table -AutoSize -Property Disk, Partitions, DriveLetter, EbsVolumeId, Device, VirtualDevice, VolumeName

按如下方式编辑脚本：

PS C:\> .\mapping.ps1

以下是具有一个根卷、两个 EBS 卷和两个实例存储卷的实例的输出示例。

Disk Partitions DriveLetter EbsVolumeId           Device    VirtualDevice VolumeName
---- ---------- ----------- -----------           ------    ------------- ----------
   0          1 C           vol-03683f1d861744bc7 /dev/sda1 root
   1          1 D           vol-082b07051043174b9 xvdb      N/A
   2          1 E           vol-0a4064b39e5f534a2 xvdc      N/A
   3          1 F           AWS-6AAD8C2AEEE1193F0 Ephemeral N/A           Temporary Storage
   4          1 G           AWS-13E7299C2BD031A28 Ephemeral N/A           Temporary Storage

如果您没有在 Windows 实例上为 Tools for Windows PowerShell 提供凭证，则脚本将无法获取 EBS 卷 ID，并会在 EbsVolumeId 列中使用 N/A。
