DESCRIPTION

The New-StoragePool cmdlet creates a new storage pool using a group of physical disks exposed by a specific storage subsystem.

EXAMPLES

Example 1: Create a new storage pool using Storage Spaces

This line uses the **Get-PhysicalDisk** cmdlet to get all PhysicalDisk objects than are not yet in a (concrete) storage pool, and assigns the array of objects to the $PhysicalDisks variable.
PS C:\> $PhysicalDisks = (Get-PhysicalDisk -CanPool $True)

This line creates a new storage pool using the $PhysicalDisks variable to specify the disks to include from the WindowsStorage subsystem (specified with a wildcard * to remove the need to modify the friendly name for different computers).
PS C:\> New-StoragePool -FriendlyName CompanyData -StorageSubsystemFriendlyName "Windows Storage*" -PhysicalDisks $PhysicalDisks

This example creates a new storage pool named CompanyData using the Storage Spaces subsytem, using the minimum parameters, and assuming that there are no other storage subsystems attached to the computer that have available disks.

Example 2: Create a new pool and set defaults for virtual disks

PS C:\> $PhysicalDisks = (Get-PhysicalDisk -CanPool $True)
PS C:\> New-StoragePool -FriendlyName CompanyData -StorageSubsystemFriendlyName "Windows Storage*" -PhysicalDisks $PhysicalDisks -ResiliencySettingNameDefault Mirror -ProvisioningTypeDefault Thin -Verbose

This example creates a new storage pool named CompanyData using the Windows Storage subsystem and sets default values for virtual disk creation.

Example 3: Create a new storage pool, virtual disk, partition, and volume

The first line ([CODE_Snippit]$PhysicalDisks =[CODE_Snippit]…) gets the storage subsystem object for the Windows Storage subsystem, passes it to the **Get-PhysicalDisk** cmdlet, which then gets the physical disks in the specified subsystem that are available to add to a storage pool, and assigns these disks to the $PhysicalDisks variable.The second line of the command has five parts, connected by the pipeline (|). The first part ([CODE_Snippit]New-StoragePool[CODE_Snippit]…) creates a new storage pool using the physical disks in the $PhysicalDisks variable, and then passes the new storage pool down the pipeline. All of the following commands are logically part of one command and should be entered as such.The second part ([CODE_Snippit]New-VirtualDisk[CODE_Snippit]…) creates a new virtual disk on the passed in storage pool and then passes the new virtual disk down the pipeline.The third part ([CODE_Snippit]Initialize-Disk[CODE_Snippit]…) initializes the disk that was passed in, and then passes the disk down the pipeline.The fourth part ([CODE_Snippit]New-Partition[CODE_Snippit]…) creates a new partition on the disk that was passed in, assigns it the next available drive letter, and then passes the partition down the pipeline.The final part of the command ([CODE_Snippit]Format-Volume[CODE_Snippit]) formats the partition that was passed in.
PS C:\> $PhysicalDisks = Get-StorageSubSystem -FriendlyName "Windows Storage*" | Get-PhysicalDisk -CanPool $True 
PS C:\> New-StoragePool -FriendlyName "CompanyData" -StorageSubsystemFriendlyName "Windows Storage*" -PhysicalDisks $PhysicalDisks |New-VirtualDisk -FriendlyName "UserData" -Size 100GB -ProvisioningType Thin |Initialize-Disk -PassThru |New-Partition -AssignDriveLetter -UseMaximumSize |Format-Volume

This example creates a new storage pool, and then makes use of the pipeline to create a new virtual disk in the pool, initialize the disk, create a new partition on the disk, and then format the new partition (volume). Alternatively you can use the New-Volume cmdlet to achieve a similar result in a single command.

PARAMETERS

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-AutoWriteCacheSize

Indicates whether to set the size of the write-back cache to 1 GB for all types of storage spaces, which include simple, mirror, and parity, to create from the pool. If the number or size of the solid-state drives (SSDs) or journal disks in the storage pool is not sufficient and you specify a value of $True for this parameter, the cmdlet sets the write-back cache size to 0 for simple and mirror spaces, and to 32 MB for parity spaces.

Type: Boolean
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-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.

Type: CimSession[]
Parameter Sets: (All)
Aliases: Session

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-EnclosureAwareDefault

Specifies the default allocation policy for virtual disks created in an enclosure-aware storage pool. For example, an enclosure-aware subsystem could balance each data copy of the virtual disk across multiple physical enclosures such that each enclosure contains a full data copy of the virtual disk.

Type: Boolean
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False

-FaultDomainAwarenessDefault

Specifies the default fault domain for new virtual disks created in this storage pool. The acceptable values for this parameter are:

  • PhysicalDisk
  • StorageScaleUnit
  • StorageChassis
  • StorageEnclosure
  • StorageRack

The fault domain specifies at what level you want to be fault tolerant. For example, specify StorageScaleUnit to store data copies on separate nodes of a Storage Spaces Direct cluster. This cmdlet refers to nodes of a Storage Spaces Direct cluster as storage scale units because you can expand the scale of the cluster by adding more nodes.
