Powershell / WMI para mapear IDs de dispositivos de drives montados para letras maiúsculas

1

Agora, estou usando essas duas consultas do WMI para obter informações sobre unidades em uma máquina:

get-wmiObject -Class Win32_LogicalDisk -Namespace root\CIMV2
-Computername $name


get-wmiObject -Class Win32_DiskDrive -Namespace root\CIMV2
-Computername $name

O primeiro dá-me DeviceIDs que se referem a letras de unidade e, em seguida, algumas informações sobre essas unidades (incluindo números de série de volume, etc.)

O segundo me dá DeviceIDs que mapeiam para \\.\PHYSICALDRIVE# e informações como o número de série (parece ser diferente) Partições, índices, portas / ids scsi e assim por diante.

Eu também vi coisas como Win32_DiskDriveToDiskPartition , que vai dar coisas como Disk # e Partition # e Disk Index.

A minha pergunta é: existem maneiras / valores comuns que podem ser consultados onde ele verifica se o DeviceID de Win32_DiskDrive está mapeado como um volume em qualquer lugar e o volume (ou os volumes)?

Eu sei que tem que haver uma maneira, há tantos objetos Win32 que não tenho certeza qual o valor para rastreá-los. Qualquer ajuda seria tremendamente útil! Idealmente, eu gostaria de poder definir uma função que chama um nome de computador e lista todos os dispositivos de disco, todos os volumes e indica quais letras de volume estão em qual unidade.

Powershell/WMI to map mounded drive device IDs to Volume Letter

My question is are there ways/common values which can be queried where it checks if DeviceID from Win32_DiskDrive is mapped as a volume anywhere and what that volume (or those volumes) are?

Parece que a classe Win32_Volume é o que você precisa usar. Dá os valores de DeviceID e da letra da unidade

Exemplo de sintaxe do PowerShell 1

get-wmiObject -Class Win32_Volume -Namespace root\CIMV2 | Format-List -Property Name, DriveLetter, __Path, DeviceID

Exemplo de sintaxe do PowerShell 2

get-wmiObject -Class Win32_Volume -Namespace root\CIMV2

My question is are there ways/common values which can be queried where it checks if DeviceID from Win32_DiskDrive is mapped as a volume anywhere and what that volume (or those volumes) are?

I know there has to be a way, there are just so many Win32 objects that I'm not sure which value to track across them. Any help would be tremendously helpful! Ideally I'd like to be able to define a function which calls a computer name and lists all disk devices, all volumes, and indicates which volume letters are on which drive.

(Forneça o script do PowerShell abaixo como uma função da captura. Você pode executá-lo localmente ou executá-lo em uma máquina remota. Consulte o hiperlink para obter detalhes completos a partir da origem.)

Depois de criar a função, você simplesmente executa algumas maneiras diferentes:

  1. Get-RemoteDiskInformation pressione enter para obter detalhes sobre disco e volume locais
  2. Get-RemoteDiskInformation -ComputerName <ComputerName> para obter detalhes sobre disco e volume de um sistema remoto

Function Get-RemoteDiskInformation
{
    <#
    .SYNOPSIS
       Get inventory data for specified computer systems.
    .DESCRIPTION
       Gather inventory data for one or more systems using wmi. Data proccessing utilizes multiple runspaces
       and supports custom timeout parameters in case of wmi problems. You can optionally include 
       drive, memory, and network information in the results. You can view verbose information on each 
       runspace thread in realtime with the -Verbose option.
    .PARAMETER ComputerName
       Specifies the target computer for data query.
    .PARAMETER ThrottleLimit
       Specifies the maximum number of systems to inventory simultaneously 
    .PARAMETER Timeout
       Specifies the maximum time in second command can run in background before terminating this thread.
    .PARAMETER ShowProgress
       Show progress bar information
    .PARAMETER PromptForCredential
       Prompt for remote system credential prior to processing request.
    .PARAMETER Credential
       Accept alternate credential (ignored if the localhost is processed)
    .EXAMPLE
       PS > Get-RemoteDiskInformation -ComputerName test1

       Description
       -----------
       Query and display disk related information about test1

    .EXAMPLE
       PS > $cred = Get-Credential
       PS > Get-RemoteDiskInformation -ComputerName Test1 -Credential $cred

Você provavelmente poderia expandir essa função com um pequeno teste e leitura para obter mais detalhes de outras classes e valores WMI a serem plugados; Abaixo estão alguns que eu encontrei para dar bons detalhes relacionados à sua pergunta para um ponto de partida com essa tarefa.

Get-WMIObject -Class Win32_Volume | Select-Object -Property *
Get-WMIObject -Class Win32_DiskDrive | Select-Object -Property *
Get-WmiObject -Class Win32_DiskPartition | Select-Object -Property *
Get-WMIObject -Class Win32_LogicalDisk | Select-Object -Property *
Get-WMIObject -Class Win32_LogicalDiskToPartition | Select-Object -Property *
