-FriendlyName <String>
-StoragePoolUniqueId <String[]> Description
The New-VirtualDisk cmdlet creates a new virtual disk in the specified storage pool.
Examples
Example 1: Creating a 100 GB virtual disk using default settings
PS C:\>New-VirtualDisk -StoragePoolFriendlyName CompanyData -FriendlyName UserData -Size 100GBThis 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.
Example 2: Creating a thinly-provisioned mirror
PS C:\>New-VirtualDisk -StoragePoolFriendlyName CompanyData -FriendlyName DataWarehouse -ResiliencySettingName Mirror -Size 42TB -ProvisioningType ThinThis example creates a virtual disk named DataWarehouse, which is 42TB in size, uses the Mirror resiliency setting, and is thinly provisioned.
Example 3: Creating a three-way mirror
PS C:\>New-VirtualDisk -StoragePoolFriendlyName CompanyData -FriendlyName BusinessCritical -ResiliencySettingName Mirror -NumberOfDataCopies 3 -Size 42TB -ProvisioningType ThinThis 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).
Example 4: Creating a two-column mirror
PS C:\>New-VirtualDisk -StoragePoolFriendlyName CompanyData -FriendlyName BusinessCritical -ResiliencySettingName Mirror - -Size 42TB -ProvisioningType Thin -NumberOfColumns 2This 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.

| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-NumberOfColumns
Specifies the number of columns to use when allocating the virtual disk.

| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-NumberOfDataCopies
Specifies the number of data copies to create. Specify 2 to create a two-way mirror, or 3 to specify a three-way mirror.
| Type: | UInt16 |
| Position: | Named |
| Default value: | 1 |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-OtherUsageDescription
Specifies an OtherUsageDescription string for the virtual disk. You can use the OtherUsageDescription parameter only if you set the Usage parameter to Other or do not include the Usage parameter.
| Type: | String |

| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
