在 PowerShell 中结合“Get-Disk”信息和“LogicalDisk”信息？

Question

我有这个扫描所有逻辑磁盘信息的查询：

Write-Host "Drive information for $env:ComputerName"

Get-WmiObject -Class Win32_LogicalDisk |
    Where-Object {$_.DriveType -ne 5} |
    Sort-Object -Property Name | 
    Select-Object Name, VolumeName, VolumeSerialNumber,SerialNumber, FileSystem, Description, VolumeDirty, `
        @{"Label"="DiskSize(GB)";"Expression"={"{0:N}" -f ($_.Size/1GB) -as [float]}}, `
        @{"Label"="FreeSpace(GB)";"Expression"={"{0:N}" -f ($_.FreeSpace/1GB) -as [float]}}, `
        @{"Label"="%Free";"Expression"={"{0:N}" -f ($_.FreeSpace/$_.Size*100) -as [float]}} |
    Format-Table -AutoSize

The output is：

但是 - 我在物理磁盘信息及其分区/卷信息之后：

所以 - 对于物理磁盘，我有这个命令：

Get-Disk

Result：

问题：

我想结合这两个命令。我想查看每个磁盘下方的磁盘、和 - 它的逻辑磁盘信息：

• 磁盘编号 1 : ....(info)
  >其逻辑磁盘信息.....
• 磁盘编号 2 : ....(info)
  >这是逻辑磁盘信息.....
• 磁盘编号 3 : ....(info)
  >这是逻辑磁盘信息.....
• 等等...

如何在这两个查询之间进行组合？

Answer 1

您需要查询多个 WMI 类才能获得所需的所有信息。

• Win32_DiskDrive 为您提供有关物理磁盘的信息。
• Win32_DiskPartition 为您提供有关物理磁盘分区的信息。
• Win32_LogicalDisk 为您提供有关分区内文件系统的信息。

可以使用Win32_DiskDriveToDiskPartition 类将分区映射到它们的磁盘，并且可以通过Win32_LogicalDiskToPartition 类将驱动器映射到它们的分区。

Get-WmiObject Win32_DiskDrive | ForEach-Object {
  $disk = $_
  $partitions = "ASSOCIATORS OF " +
                "{Win32_DiskDrive.DeviceID='$($disk.DeviceID)'} " +
                "WHERE AssocClass = Win32_DiskDriveToDiskPartition"
  Get-WmiObject -Query $partitions | ForEach-Object {
    $partition = $_
    $drives = "ASSOCIATORS OF " +
              "{Win32_DiskPartition.DeviceID='$($partition.DeviceID)'} " +
              "WHERE AssocClass = Win32_LogicalDiskToPartition"
    Get-WmiObject -Query $drives | ForEach-Object {
      New-Object -Type PSCustomObject -Property @{
        Disk        = $disk.DeviceID
        DiskSize    = $disk.Size
        DiskModel   = $disk.Model
        Partition   = $partition.Name
        RawSize     = $partition.Size
        DriveLetter = $_.DeviceID
        VolumeName  = $_.VolumeName
        Size        = $_.Size
        FreeSpace   = $_.FreeSpace
      }
    }
  }
}

这样怎么样……

Get-CimInstance Win32_Diskdrive -PipelineVariable disk |
Get-CimAssociatedInstance -ResultClassName Win32_DiskPartition -pv partition |
Get-CimAssociatedInstance -ResultClassName Win32_LogicalDisk |
Select-Object @{n='Disk';e={$disk.deviceid}},
@{n='DiskSize';e={$disk.size}},
@{n='DiskModel';e={$disk.model}},
@{n='Partition';e={$partition.name}},
@{n='RawSize';e={$partition.size}},
@{n='DriveLetter';e={$_.DeviceID}},
VolumeName,Size,FreeSpace

输出：

Disk        : \\.\PHYSICALDRIVE0
DiskSize    : 128034708480
DiskModel   : SAMSUNG MZ7PC128HAFU-000L5
Partition   : Disk #0, Partition #0
RawSize     : 128034595328
DriveLetter : C:
VolumeName  : DISK
Size        : 128034594816
FreeSpace   : 7023042560

不幸的是，这不适用于多个驱动器。像 sort-object 一样获取 cimassociatedinstance 块，并且只设置最新的管道变量。这是一个解决方法：

Get-CimInstance Win32_Diskdrive -PipelineVariable disk |
% { Get-CimAssociatedInstance $_ -ResultClass Win32_DiskPartition -pv partition}|
% { Get-CimAssociatedInstance $_ -ResultClassName Win32_LogicalDisk } |
Select-Object @{n='Disk';e={$disk.deviceid}},
@{n='DiskSize';e={$disk.size}},
@{n='DiskModel';e={$disk.model}},
@{n='Partition';e={$partition.name}},
@{n='RawSize';e={$partition.size}},
@{n='DriveLetter';e={$_.DeviceID}},
VolumeName,Size,FreeSpace

Disk        : \\.\PHYSICALDRIVE0
DiskSize    : 128034708480
DiskModel   : SAMSUNG MZ7PC128HAFU-000L5
Partition   : Disk #0, Partition #0
RawSize     : 128034595328
DriveLetter : C:
VolumeName  : DISK
Size        : 128034594816
FreeSpace   : 4226514944

Disk        : \\.\PHYSICALDRIVE1
DiskSize    : 7797565440
DiskModel   : USB Flash Memory USB Device
Partition   : Disk #1, Partition #0
RawSize     : 7801405440
DriveLetter : E:
VolumeName  : WINPE
Size        : 7784628224
FreeSpace   : 7222669312

灵感来自 js2010 的答案，并进行了一些改进：

例如，Manufacturer 字段在从 Win32_DiskDrive 实例检索时似乎具有一些占位符值，但在使用 Get-Disk 命令行开关时具有正确的值。

function Get-Drive {

  foreach($disk in Get-CimInstance Win32_Diskdrive) {

    $diskMetadata = Get-Disk | Where-Object { $_.Number -eq $disk.Index } | Select-Object -First 1

    $partitions = Get-CimAssociatedInstance -ResultClassName Win32_DiskPartition -InputObject $disk

    foreach($partition in $partitions) {

      $drives = Get-CimAssociatedInstance -ResultClassName Win32_LogicalDisk -InputObject $partition

      foreach($drive in $drives) {

        $totalSpace = [math]::Round($drive.Size / 1GB, 3)
        $freeSpace  = [math]::Round($drive.FreeSpace / 1GB, 3)
        $usedSpace  = [math]::Round($totalSpace - $freeSpace, 3)

        $volume     = Get-Volume |
                      Where-Object { $_.DriveLetter -eq $drive.DeviceID.Trim(":") } |
                      Select-Object -First 1

        [PSCustomObject] @{
                            DriveLetter   = $drive.DeviceID
                            Number        = $disk.Index

                            Label         = $volume.FileSystemLabel
                            Manufacturer  = $diskMetadata.Manufacturer
                            Model         = $diskMetadata.Model
                            SerialNumber  = $diskMetadata.SerialNumber.Trim() 
                            Name          = $disk.Caption

                            FileSystem    = $volume.FileSystem
                            PartitionKind = $diskMetadata.PartitionStyle

                            TotalSpace    = $totalSpace
                            FreeSpace     = $freeSpace
                            UsedSpace     = $usedSpace

                            Drive         = $drive
                            Partition     = $partition
                            Disk          = $disk
        }

      }
    }
  }
}           

示例用法：

Get-Drive | Format-List
Get-Drive | Where-Object { $_.DriveLetter -eq 'G:' }

输出：

DriveLetter   : G:
Number        : 5
Label         : SE-LXY2-298GB
Manufacturer  : Seagate
Model         : FreeAgent Go
SerialNumber  : 2GE45CK1
Name          : Seagate FreeAgent Go USB Device
FileSystem    : NTFS
PartitionKind : MBR
TotalSpace    : 298.089
FreeSpace     : 297.865
UsedSpace     : 0.224
Drive         : Win32_LogicalDisk: G: (DeviceID = "G:")
Partition     : Win32_DiskPartition: Disk #5, Partition #0 (DeviceID = "Disk #5, Partition #0")
Disk          : Win32_DiskDrive: Seagate FreeAgent Go USB Device (DeviceID = "\\.\PHYSICALDRIVE5")
