Data [in]

IPMI request data and context data. The request data block contains the number of bytes specified in RequestDataSize, followed by the context data. The context data block size in bytes is DataSize minus RequestDataSize.

DataSize [in]

Number of bytes in IPMI request and context data.

Lun [in]

Logical unit number to which IPMI request is sent.

NetworkFunction [in]

Network function for the IPMI request.

RequestDataSize [in]

Number of bytes in IPMI request data.

ResponderAddress [in]

Responder address to which IPMI request is sent.

ResponseData [out]

IPMI response data. Completion code is present in response data.

ResponseDataSize [out]

Number of bytes in RequestData. Completion code is included in this size.

Return value

This method does not return a value.
