The SRV_COPYCHUNK_RESPONSE packet is sent to the client by the server in an SMB2 IOCTL Response for FSCTL_SRV_COPYCHUNK or FSCTL_SRV_COPYCHUNK_WRITE requests to return the results of a server-side copy operation. It is placed in the Buffer field of the SMB2 IOCTL Response packet. This packet consists of the following:

TotalBytesWritten

ChunksWritten (4 bytes): If the Status field in the SMB2 header of the response is not STATUS_INVALID_PARAMETER, as specified in [MS-ERREF] section 2.3, this value indicates the number of chunks that were successfully written. If the Status field in the SMB2 header of the response is STATUS_INVALID_PARAMETER, this value indicates the maximum number of chunks that the server will accept in a single request. This would allow the client to correctly reissue the request.

ChunkBytesWritten (4 bytes): If the Status field in the SMB2 header of the response is not STATUS_INVALID_PARAMETER, as specified in [MS-ERREF] section 2.3, this value indicates the number of bytes written in the last chunk that did not successfully process (if a partial write occurred). If the Status field in the SMB2 header of the response is STATUS_INVALID_PARAMETER, this value indicates the maximum number of bytes the server will allow to be written in a single chunk.

TotalBytesWritten (4 bytes): If the Status field in the SMB2 header of the response is not STATUS_INVALID_PARAMETER, as specified in [MS-ERREF] section 2.3, this value indicates the total number of bytes written in the server-side copy operation. If the Status field in the SMB2 header of the response is STATUS_INVALID_PARAMETER, this value indicates the maximum number of bytes the server will accept to copy in a single request.
