Description

The Set-StorageTier cmdlet modifies a storage tier. Use this cmdlet to change the name and description of a storage tier, and to change the media type that is associated with storage tier.

Examples

Example 1: Change the name of a storage tier

PS C:\> Set-StorageTier -UniqueId '{49dde1c4-5c34-11e2-8441-00155de88701}' -NewFriendlyName "FastTier"

This command changes the friendly name of the storage tier that has the specified ID.

Example 2: Change the description of a storage tier

PS C:\> Get-StorageTier -FriendlyName "FastTier" | Set-StorageTier -Description "This tier denotes fast media in the system"

This command uses the Get-StorageTier cmdlet to get the storage tier named FastTier, and then passes the storage tier to the Set-StorageTier cmdlet by using the pipeline operator. The Set-StorageTier cmdlet changes the description of the storage tier to the specified string.

Parameters

-AsJob

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

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
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[]
Aliases:	Session
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-ColumnIsolation

Specifies at which level columns within a virtual disk should be isolated from each other. We recommend omitting this parameter and using the defaults. The acceptable values for this parameter are:

• PhysicalDisk
• StorageScaleUnit
• StorageChassis
• StorageEnclosure
• StorageRack

Type:	FaultDomainType
Accepted values:	PhysicalDisk, StorageEnclosure, StorageScaleUnit, StorageChassis, StorageRack
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Description

Specifies a description for the storage tier.

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

-FaultDomainAwareness

Specifies at what level you want the storage tier to be fault tolerant. The acceptable values for this parameter are:

• PhysicalDisk
• StorageScaleUnit
• StorageChassis
• StorageEnclosure
• StorageRack

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.

Type:	FaultDomainType
Accepted values:	PhysicalDisk, StorageEnclosure, StorageScaleUnit, StorageChassis, StorageRack
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-FriendlyName

Specifies the friendly name of the storage tier to modify.

Type:	String
Position:	0
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-InputObject

Specifies the input object that is used in a pipeline command.

Type:	CimInstance[]
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-Interleave

Specifies the interleave value to use during the creation of a virtual disk. The interleave value represents the number of bytes that is written to a single physical disk. Therefore, Interleave * NumberOfColumns yields the size of one stripe of user data.

Type:	UInt64
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-MediaType

Specifies the media type of the storage tier. The acceptable values for this parameter are:

• SSD
• SCM
• HDD

Use SCM for storage-class memory such as NVDIMMs.

Type:	MediaType
Accepted values:	HDD, SSD, SCM
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-NewFriendlyName

Specifies a new friendly name for the storage tier.

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

-NumberOfColumns

Specifies the number of columns to use when allocating the storage tier.

Type:	UInt16
Position:	Named
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 or for dual-parity.

Type:	UInt16
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-NumberOfGroups

Specifies the number of groups used by Local Reconstruction Coding (LRC) with a dual parity virtual disk. We recommend omitting this parameter and using the defaults.

Type:	UInt16
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-PhysicalDiskRedundancy

Specifies the physical disk redundancy value to use during the creation of a virtual disk. This value represents how many failed physical disks the virtual disk can tolerate without data loss. The redundancy values are as follows:

• For two-way mirror spaces, the virtual disk can tolerate 1 failed physical disk without data loss.
• For three-way mirror spaces, the virtual disk can tolerate 2 failed physical disks without data loss.
• For single-parity spaces, the virtual disk can tolerate 1 failed physical disk without data loss.
• For dual-parity spaces the virtual disk can tolerate 2 failed physical disks without data loss.

Type:	UInt16
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-ResiliencySettingName

Specifies the resiliency setting, or storage layout, to use for the virtual disk. Acceptable values vary by storage subsystem.

Allowed values for the Windows Storage subsystem are: Simple, Mirror, or Parity. By default, when you specify Mirror, Storage Spaces creates a two-way mirror, and when you specify Parity, Storage Spaces creates a single-parity space.

To create a three-way mirror space, specify 3 for the NumberofDataCopies parameter or 2 for the PhysicalDiskRedundancy parameter.

To create a dual-parity space, specify 2 for the PhysicalDiskRedundancy parameter and Fixed provisioning for the ProvisioningType parameter.

Type:	String
Position:	Named
Default value:	None
Required:	False
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 PowerShell® 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.

Type:	Int32
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-UniqueId

Specifies the unique ID of the storage tier to modify.

Type:	String
Aliases:	Id
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

Inputs

CimInstance

You can use the pipeline operator to pass an array of MSFT_StorageTier objects to the InputObject parameter.

Outputs

CimInstance

This cmdlet returns an MSFT_StorageTier object that contains details about the tier such as tier friendly name, media type and size.

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.
• When used in Failover Cluster, cmdlets from the Storage module operate on cluster level (all servers in the cluster).
