Detailed Description

The New-VirtualDisk cmdlet creates a new virtual disk in the specified storage pool.

Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see    about_CommonParameters.

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_StoragePool

    You can pipe an MSFT_StoragePool object to the InputObject parameter.


Outputs

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

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

    The New-VirtualDisk cmdlet returns an object that represents the newly created virtual disk.


Notes

  • 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.

Examples

Example 1: Creating a 100 GB virtual disk using default settings

This example creates a virtual disk named UserData from the storage pool named CompanyData that is 100GB in size, using the storage pool default settings for unspecified parameters.


PS C:\> New-VirtualDisk -StoragePoolFriendlyName CompanyData -FriendlyName UserData -Size 100GB

Example 2: Creating a thinly-provisioned mirror

This example creates a virtual disk named DataWarehouse, which is 42TB in size, uses the Mirror resiliency setting, and is thinly provisioned.


PS C:\> New-VirtualDisk -StoragePoolFriendlyName CompanyData -FriendlyName DataWarehouse –ResiliencySettingName Mirror -Size 42TB -ProvisioningType Thin

Example 3: Creating a three-way mirror

This example creates a 42 TB thinly-provisioned virtual disk on the Storage Spaces subsystem, using the Mirror resiliency setting with three data copies. This creates a three-way mirror that is capable of tolerating two disk failures).


PS C:\> New-VirtualDisk -StoragePoolFriendlyName CompanyData -FriendlyName BusinessCritical -ResiliencySettingName Mirror -NumberOfDataCopies 3 -Size 42TB -ProvisioningType Thin

Example 4: Creating a two-column mirror

This example creates a thinly-provisioned virtual disk on the Storage Spaces subsystem that uses two columns, regardless of how many physical disks are in the storage pool above the two-disk minimum for a two-way mirror.


PS C:\> New-VirtualDisk -StoragePoolFriendlyName CompanyData -FriendlyName BusinessCritical -ResiliencySettingName Mirror - -Size 42TB -ProvisioningType Thin -NumberOfColumns 2
