Description

The Enable-StorageHighAvailability cmdlet enables a clusterable disk that is not yet a cluster resource to be added to the failover cluster.

Examples

Example 1: Enable a disk in a failover cluster by using its ID

This command uses the Get-Disk cmdlet to display the properties of disk number 9.
PS C:\>Get-Disk -Number 9 | Format-Table -Property Number,IsHighlyAvailable,IsClustered,IsScaleOut
Number IsHighlyAvailable IsClustered IsScaleOut
------ ----------------- ----------- ----------
     9             False       False      False

The next command enables disk number 9. The final command repeats the first command to display the new status of the disk.
PS C:\>Enable-StorageHighAvailability -DiskNumber 9
PS C:\> Get-Disk -Number 9 | Format-Table Number,IsHighlyAvailable,IsClustered,IsScaleOut
Number IsHighlyAvailable IsClustered IsScaleOut
------ ----------------- ----------- ----------
     9              True        True       True

This command enables a shared disk to be added to the failover cluster and made a Cluster Shared Volume by using the disk number as the identifier of the disk to enable.

Example 2: Enable a disk for failover cluster without it being enabled for Cluster Shared Volumes

This command uses **Get-Disk** to display the properties of disk number 9.
PS C:\>Get-Disk -Number 9 | Format-Table -Property Number,IsHighlyAvailable,IsClustered,IsScaleOut

Number IsHighlyAvailable IsClustered IsScaleOut
------ ----------------- ----------- ----------
     9             False       False      False


The next command enables disk number 9. The command specifies a value of 0 for the *Scaleout* parameter. This command leaves the disk in available storage and not enabled. The final command repeats the first command to display the new status of the disk.
PS C:\>Enable-StorageHighAvailability -DiskNumber 9 -ScaleOut 0
PS C:\> Get-Disk -Number 9 | Format-Table Number,IsHighlyAvailable,IsClustered,IsScaleOut

Number IsHighlyAvailable IsClustered IsScaleOut
------ ----------------- ----------- ----------
     9              True        True      False

This example enables a shared disk to be added to the failover cluster and made a Cluster Shared Volume by using the disk number. The example makes the disk available but enabled for Cluster Shared Volume.

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

-DiskFriendlyName

Specifies an array of friendly names for disks.

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

-DiskNumber

Specifies an array of disk numbers.

Type:UInt32[]
Position:0
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-DiskPath

Specifies an array of disk paths.

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

-DiskUniqueId

Specifies an array of disk IDs.

Type:String[]
Aliases:DiskId
Position:Named
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

-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

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

-ScaleOut

Type:Boolean
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

Notes

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