Detailed Description

The Enable-PhysicalDiskIndication cmdlet enables the identification LED on the specified physical disk. The LED is typically used for visual identification of the location of a physical disk in an enclosure for removal and replacement operations. This cmdlet requires a storage enclosure that supports SCSI Enclosure Services (SES).

Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs.

-ThrottleLimit<Int32>

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.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see    about_CommonParameters.

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

Outputs

The output type is the type of the objects that the cmdlet emits.

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.

Examples

Example 1: Enable the identification LED on all physical disks in a pool

This example enables the identification LED on all physical disks associated with the storage pool SpacePool. This is useful for identifying a specific virtual disk, when the LED on the disk in question is not functioning.


PS C:\> $stpool = (Get-StoragePool -FriendlyName "SpacePool")
PS C:\> Enable-PhysicalDiskIndication -StoragePool $stpool

Example 2: Enable the identification LED on all physical disks used by a virtual disk

This example enables the identification LED on all physical disks associated with the virtual disk named Bruce’s Music to visually identify the physical disk associated with the virtual disk.


PS C:\> $vdisk = (Get-VirtualDisk -FriendlyName "Bruce's Music")
PS C:\> Enable-PhysicalDiskIndication -VirtualDisk $vdisk

Example 3: Enable the identification LED on all disks that are not healthy

This example gets all physical disks with a health status that is not Healthy, and pipes the disks to the Enable-PhysicalDiskIndication cmdlet, enabling the LEDs on the disks, if supported by the drive enclosure.


PS C:\> Get-PhysicalDisk | Where-Object -FilterScript { $_.HealthStatus –Ne "healthy" } | Enable-PhysicalDiskIndication
