    Creates one or more virtual tapes. You write data to the virtual tapes and then archive the tapes. This operation is only supported in the tape gateway architecture.

    Examples
    Creates one or more virtual tapes.
    Expected Output:
    
    :example: response = client.create_tapes(
        GatewayARN='string',
        TapeSizeInBytes=123,
        ClientToken='string',
        NumTapesToCreate=123,
        TapeBarcodePrefix='string'
    )
    
    
    :type GatewayARN: string
    :param GatewayARN: [REQUIRED]
            The unique Amazon Resource Name (ARN) that represents the gateway to associate the virtual tapes with. Use the ListGateways operation to return a list of gateways for your account and region.
            

    :type TapeSizeInBytes: integer
    :param TapeSizeInBytes: [REQUIRED]
            The size, in bytes, of the virtual tapes that you want to create.
            Note
            The size must be aligned by gigabyte (1024*1024*1024 byte).
            

    :type ClientToken: string
    :param ClientToken: [REQUIRED]
            A unique identifier that you use to retry a request. If you retry a request, use the same ClientToken you specified in the initial request.
            Note
            Using the same ClientToken prevents creating the tape multiple times.
            

    :type NumTapesToCreate: integer
    :param NumTapesToCreate: [REQUIRED]
            The number of virtual tapes that you want to create.
            

    :type TapeBarcodePrefix: string
    :param TapeBarcodePrefix: [REQUIRED]
            A prefix that you append to the barcode of the virtual tape you are creating. This prefix makes the barcode unique.
            Note
            The prefix must be 1 to 4 characters in length and must be one of the uppercase letters from A to Z.
