Parameters

-AsJob: Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
-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.
-FriendlyName: Gets the disk with the specified friendly name. Enter a friendly name, or use wildcard characters to enter a name pattern.
-Number: Specifies the disk number for which to get the associated Disk object.
-Partition: Accepts a Partition object as input. The Partition CIM object is exposed by the Get-Partition cmdlet.
-Path: Contains valid path information.
-SerialNumber: Specifies an array of serial numbers associated with disks that this cmdlet gets.
-StorageJob: Specifies a storage job object that is associated with disks that this cmdlet gets. To obtain a storage job, use the Get-StorageJob cmdlet.
-StorageSubSystem: Specifies the storage subsystem from which this cmdlet gets disks. To obtain a StorageSubsystem object, use the Get-StorageSubSystem cmdlet.
-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.
-UniqueId: Gets only the disks with the specified IDs. Type one or more IDs (separated by commas).
-VirtualDisk: Accepts a VirtualDisk object as input. The Virtual Disk CIM object is exposed by the Get-VirtualDisk cmdlet.
-iSCSIConnection: Accepts an iSCSIConnection object as input. The iSCSI Connection CIM object is exposed by the Get-IscsiConnection cmdlet.
-iSCSISession: Accepts an iSCSISession object as input. The iSCSI Session CIM object is exposed by the Get-IscsiSession cmdlet.

Prerequisites
