docs: // RetrieveTapeArchive API operation for AWS Storage Gateway.
  //
  // Retrieves an archived virtual tape from the virtual tape shelf (VTS) to a
  // tape gateway. Virtual tapes archived in the VTS are not associated with any
  // gateway. However after a tape is retrieved, it is associated with a gateway,
  // even though it is also listed in the VTS, that is, archive. This operation
  // is only supported in the tape gateway type.
  //
  // Once a tape is successfully retrieved to a gateway, it cannot be retrieved
  // again to another gateway. You must archive the tape again before you can
  // retrieve it to another gateway. This operation is only supported in the tape
  // gateway type.
  //
  // Returns awserr.Error for service API and SDK errors. Use runtime type assertions
  // with awserr.Error's Code and Message methods to get detailed information about
  // the error.
  //
  // See the AWS API reference guide for AWS Storage Gateway's
  // API operation RetrieveTapeArchive for usage and error information.
