docs: // Enable or disable the mounting of a Storage volume. When mounting is enabled the Storage volume will be mountable or available for use.
  //
  // For Virtual Server volumes, disabling mounting will deny access to the Virtual Server Account, remove published material and deny all file interaction including uploads and downloads.
  //
  // Enabling or disabling mounting for Storage volumes is not possible if mounting has been disabled by SoftLayer or a parent account.
