DESCRIPTION
The New-Volume cmdlet creates a volume with the specified file system. The cmdlet manages the creation of the
virtual disk with the specified size and resiliency setting, initializes the disk, creates a partition on it and
formats the volume with the specified file system, including Cluster Shared Volumes (CSVs).

Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-StoragePool
Specifies the storage pool object in which you want to create a volume. To obtain a storage pool object, use
the Get-StoragePool cmdlet.
Required? true
Position? 1

Accept pipeline input? true(ByValue)
Accept wildcard characters? false
-StoragePoolFriendlyName
Specifies the friendly name of the storage pool in which to create a volume.

Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-ThrottleLimit []
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 PowerShellr 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.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-UseMaximumSize []
Indicates that this cmdlet creates the largest volumn possible.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-WriteCacheSize []
Specifies the size of the write-back cache. The cmdlet creates the write-back cache of the size that you
specify when the cmdlet creates the virtual disk space.
The following describes the behavior of this parameter based on the value that you specify:
-- 1. If you do not specify this parameter, the cmdlet sets the value of the WriteCacheSizeDefault property
from the storage pool.
-- 2. The default setting of WriteCacheSizeDefault for a storage pool is Auto, which specifies that Windows
Server automatically selects the optimal write-back cache size for your configuration. You can change the
value of WriteCacheSizeDefault to a concrete value at any time.
-- 3. The Auto setting for WriteCacheSize operates as follows:
---- a. If any of the following is true, Auto is set to 1 GB:
------ i. The storage pool contains at least N drives with enough capacity and you set the Usage parameter to
Journal. N = 1 for simple spaces, N = 2 for two-way mirror and single parity, N = 3 for three-way mirror and
dual parity.
------ ii. The storage pool contains at least N drives with enough capacity and the media type of the virtual
disk is set to SSD. N = 1 for simple spaces, N = 2 for two-way mirror and single parity, N = 3 for three-way
mirror and dual parity.
---- b. Otherwise, Auto is set to 0 (no log) for simple and mirror spaces, and 32 MB for parity spaces.
-- 4. If you specify Auto or 0 (zero) for this parameter and the storage space is not a parity space, the
cmdlet verifies that either 3.a.i or 3.a.ii is true. If either 3.a.i or 3.a.ii is not true, you cannot set
WriteCacheSize to Auto or 0.
---- a. The objective of these conditions is to help you avoid scenarios in which you force the creation of a
write-back cache in situations that result in slower performance.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
This cmdlet supports the common parameters: Verbose, Debug,
ErrorAction, ErrorVariable, WarningAction, WarningVariable,
OutBuffer, PipelineVariable, and OutVariable. For more information, see

INPUTS
Microsoft.Management.Infrastructure.CimInstance#ROOT/Microsoft/Windows/Storage/MSFT_StoragePool
http://msdn.microsoft.com/library/windows/desktop/hh830551.aspx
You can use the pipeline operator to pass an MSFT_StoragePool object to the InputObject parameter.
OUTPUTS
Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/Storage/MSFT_Volume
http://msdn.microsoft.com/library/windows/desktop/hh830604.aspx
This cmdlet outputs an object that represents the newly created volume.
NOTES
To create a volume on a new storage space with enclosure-awareness enabled (providing resiliency for an entire
JBOD enclosure failure), use the Set-StoragePool cmdlet with the -EnclosureAwareDefault $true parameter to set
the storage pool to create storage spaces with enclosure awareness enabled by default.
Example 1: Create a volume on a mirror space
PS C:\> New-Volume -StoragePoolName "CompanyData" -FriendlyName "TestVolume" -Size 10GB -ResiliencySettingName
"Mirror" -FileSystem NTFS -AccessPath "M: "-ProvisioningType Fixed
This command creates a new storage space in the CompanyData pool using the Mirror resiliency setting and fixed
provisioning, and then formats the volume with the NTFS file system and assigns drive letter M.
Example 2: Create a volume on a new tiered storage space
PS C:\>New-Volume -StoragePoolFriendlyName "CompanyData" -FriendlyName "UserData" -AccessPath "M:"
-ResiliencySettingName "Mirror" -ProvisioningType "Fixed" -StorageTiers (Get-StorageTier -FriendlyName "*SSD*"),
(Get-StorageTier -FriendlyName "*HDD*") -StorageTierSizes 20GB, 80GB -FileSystem NTFS
This command creates new storage space in the CompanyData pool using the Mirror resiliency setting, fixed
provisioning, a 20 GB SSD storage tier, and an 80 GB HDD storage tier, and then formats the volume with the NTFS
file system and assigns drive letter M.
