New-IscsiVirtualDisk

Updated: April 29, 2013

Applies To: Windows Server 2012

New-IscsiVirtualDisk

Creates an iSCSI virtual disk with the specified file path and size.

Syntax

Parameter Set: Fixed
New-IscsiVirtualDisk [-Size] <UInt64> [ <CommonParameters>]

Parameter Set: __AllParameterSets
New-IscsiVirtualDisk [-Path] <String> [-ComputerName <String> ] [-Credential <PSCredential> ] [-Description <String> ] [ <CommonParameters>]

Parameter Set: Differencing
New-IscsiVirtualDisk -ParentPath <String> [ <CommonParameters>]




Detailed Description

The New-IscsiVirtualDisk cmdlet creates a new iSCSI Virtual Hard Disk (VHD) object with the specified file path and size. After the iSCSI VHD object has been created, the virtual disk can be assigned to an iSCSI target. Once a virtual disk has been assigned to a target, and an initiator connects to that target, the iSCSI initiator can then access the virtual disk after the initiator connects to the target.

If the VHD file path does not exist, then a new VHD file will then be created.
If the VHD file path exists, then the server will return an error. Use the Import-IscsiVirtualDisk cmdlet to import existing VHDs.

If an error is displayed during the creation of the virtual disk, please check the following conditions:
-- An absolute file path must be specified for the Path and ParentPath parameters.
-- The virtual disk file name must have a .VHD file extension. The iSCSI software target does not support the .VHDX file extension in this release.
-- The VHD file cannot be a network file, or be in a compressed, sparse, or transacted folder.

Examples

EXAMPLE 1

This example creates a fixed VHD with 10GB in size.


PS C:\> New-IscsiVirtualDisk –Path "E:\temp\test.vhd" -Size 10GB

EXAMPLE 2

This example creates a differencing VHD, with the parent path E:\temp\test.vhd and the differencing VHD path is E:\temp\child\diff.vhd.


PS C:\> New-IscsiVirtualDisk -ParentPath "E:\temp\test.vhd" -Path "E:\temp\child\diff.vhd"

EXAMPLE 3

This example creates a fixed VHD with the size 10GB at E:\temp\test.vhd on the computer named iscsisvr.


PS C:\> New-IscsiVirtualDisk –Path "E:\temp\test.vhd" -Size 10GB -ComputerName "iscsisvr"

EXAMPLE 4

This example creates a VHD with the size 20MB. This VHD will not be saved, the VHD will be lost if the wintarget service is restarted or the system is restarted.


PS C:\> New-IscsiVirtualDisk –Path ramdisk:test –Size 20MB
