Update-Disk

Update cached information about the specified Disk object only.

Syntax
      Update-Disk
         { [-Number] UInt32[] | -UniqueId String[] | [-FriendlyName String[]] | -Path String[] | -InputObject CimInstance[] }
            [-CimSession CimSession[]] [-ThrottleLimit Int32]
               [-AsJob] [-PassThru] [CommonParameters]

Key
   -AsJob
      Run the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

   -CimSession
      Run 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
      Specifies a friendly name for a disk.
      The friendly name may be defined by a user and is not guaranteed to be unique.

   -InputObject
      The input object that is used in a pipeline command.

   -Number
      Specifies the disk number on which the cmdlet acts.

   -PassThru
      Sends items from the interactive window down the pipeline as input to other cmdlets.
      By default, this cmdlet does not generate any output. To send items from the interactive window down
      the pipeline, click to select the items and then click OK. Shift-click and Ctrl-click are supported.

   -Path
      Contains valid path information.

   -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 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
      Specifies an ID used to uniquely identify a Disk object in the system. The ID persists through restarts.

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.

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