Detailed Description

The Get-Partition cmdlet returns one or more Partition objects depending on the specified criteria. This cmdlet will return a Volume object or a set of Volume objects given parameters to be used to uniquely identify a volume, or parameters to identify a set of volumes that meet the given set of criteria.

Parameters

-AsJob

Aliases	none
Required?	false
Position?	named
Default Value	none
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-CimSession<CimSession[]>

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

Aliases	Session
Required?	false
Position?	named
Default Value	none
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-Disk<CimInstance>

Accepts a Disk object as input. The Disk CIM object is exposed by the Get-Disk cmdlet.

Aliases	none
Required?	false
Position?	named
Default Value	none
Accept Pipeline Input?	True (ByValue)
Accept Wildcard Characters?	false

-DiskId<String[]>

Specifies an ID used to identify a disk in the system.

Aliases	none
Required?	false
Position?	named
Default Value	none
Accept Pipeline Input?	True (ByPropertyName)
Accept Wildcard Characters?	false

-DiskNumber<UInt32[]>

Specifies the number of the disk.

Aliases	none
Required?	false
Position?	1
Default Value	none
Accept Pipeline Input?	True (ByPropertyName)
Accept Wildcard Characters?	false

-DriveLetter<Char[]>

Specifies a letter used to identify a drive or volume in the system. Specifically the drive on which the partition resides.

Aliases	none
Required?	false
Position?	named
Default Value	none
Accept Pipeline Input?	True (ByPropertyName)
Accept Wildcard Characters?	false

-Offset<UInt64[]>

Specifies the starting offset, in bytes.

Aliases	none
Required?	false
Position?	named
Default Value	none
Accept Pipeline Input?	True (ByPropertyName)
Accept Wildcard Characters?	false

-PartitionNumber<UInt32[]>

Specifies the number of the partition.

Aliases	Number
Required?	false
Position?	2
Default Value	none
Accept Pipeline Input?	True (ByPropertyName)
Accept Wildcard Characters?	false

-ThrottleLimit<Int32>

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Aliases	none
Required?	false
Position?	named
Default Value	none
Accept Pipeline Input?	false
Accept Wildcard Characters?	false

-Volume<CimInstance>

Accepts a Volume object as input. The Volume CIM object is exposed by the Get-Volume cmdlet.

Aliases	none
Required?	false
Position?	named
Default Value	none
Accept Pipeline Input?	True (ByValue)
Accept Wildcard Characters?	false

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see    about_CommonParameters (https://go.microsoft.com/fwlink/p/?LinkID=113216).

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

• Microsoft.Management.Infrastructure.CimInstance#ROOT/Microsoft/Windows/Storage/MSFT_Disk

  The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.

• Microsoft.Management.Infrastructure.CimInstance#ROOT/Microsoft/Windows/Storage/MSFT_VirtualDisk

  The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.

• Microsoft.Management.Infrastructure.CimInstance#ROOT/Microsoft/Windows/Storage/MSFT_Volume

  The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.

Outputs

The output type is the type of the objects that the cmdlet emits.

• Microsoft.Management.Infrastructure.CimInstance#ROOT/Microsoft/Windows/Storage/MSFT_Partitions

  The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.
