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.
-BusType: Specifies the bus type via which the device is connected to the system. The acceptable values for this parameter are: iSCSI, SAS, and FibreChannel.
-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.
-IsMultipathed: Specifies that the device is currently multipath enabled by Microsoft MPIO.
-IsSPC3Supported: Specifies whether the supported specification of the device is T10 SPC3 or a later version.
-ProductId: Specifies the product ID of the device.
-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.
-VendorId: Specifies the vendor ID of the device.

Prerequisites

Windows with the MPIO module and the Windows feature or management tools that provide it. Confirm target connectivity and version compatibility using the linked Microsoft reference.
