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.
-Confirm: Prompts you for confirmation before running the cmdlet.
-FriendlyName (required): Specifies an array of storage pool friendly names. The cmdlet upgrades the storage pools that you specify by friendly name.
-InputObject (required): Specifies the input object that is used in a pipeline command.
-Name (required): Specifies an array of names. The cmdlet upgrades the storage pools that you specify by name. This human-readable name is not necessarily unique.
-PassThru: Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
-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 (required): Specifies an array of unique IDs, as strings. The cmdlet upgrades the storage pools that have the IDs that you specify.
-WhatIf: Shows what would happen if the cmdlet runs. The cmdlet is not run.
