Powershell/WMI для сопоставления идентификаторов подключенных накопителей с буквой тома
Мой вопрос: есть ли способы / общие значения, которые можно запрашивать, когда он проверяет, отображается ли DeviceID из Win32_DiskDrive как том где-либо, и что это за том (или эти тома)?
Казалось бы, класс Win32_Volume - это то, что вам нужно использовать. Это дает ИД DeviceID и значения буквы диска
Пример синтаксиса PowerShell 1
get-wmiObject -Class Win32_Volume -Namespace root\CIMV2 | Format-List -Property Name, DriveLetter, __Path, DeviceID
Пример синтаксиса PowerShell 2
get-wmiObject -Class Win32_Volume -Namespace root\CIMV2
Мой вопрос: есть ли способы / общие значения, которые можно запрашивать, когда он проверяет, отображается ли DeviceID из Win32_DiskDrive как том где-либо, и что это за том (или эти тома)?
Я знаю, что должен быть способ, существует так много объектов Win32, что я не уверен, какое значение отслеживать через них. Любая помощь будет чрезвычайно полезна! В идеале я хотел бы иметь возможность определить функцию, которая вызывает имя компьютера и перечисляет все дисковые устройства, все тома и указывает, какие буквы тома находятся на каком диске.
(Дайте приведенный ниже скрипт PowerShell, встроенный в виде функции shot. Вы можете запустить его локально или на удаленной машине. Смотрите гиперссылку для полной информации, хотя из источника.)
Как только вы построите функцию, вы просто запустите несколько разных способов:
Get-RemoteDiskInformation нажмите Enter, чтобы получить информацию о локальном диске и томе.Get-RemoteDiskInformation -ComputerName <ComputerName> для получения сведений о диске и томе удаленной системы

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

Version Info:
1.1 - 01/04/2014
- Added missing computername property to diskelements variable
1.0 - 12/13/2013
- Initial release (kind of, this bit of code is modified from a prior function I rolled into an all inclusive system information gathering
function).
