T10/1236-D Revision 20 18 July 20019.2 RECEIVE commandThe RECEIVE command (see table 180) requests that the device server transfer data to the initiator. The contentsof the data are not defined by this standard.Table 180 — RECEIVE commandBitByte7 6 5 4 3 2 1 00 OPERATION CODE (08h)1 Reserved2 (MSB)3TRANSFER LENGTH4 (LSB)5 CONTROLThe TRANSFER LENGTH field specifies the length in bytes of data that shall be transferred to the Data-In Buffer. Atransfer length of zero indicates that no data shall be sent. This condition shall not be considered an error.9.3 SEND commandThe SEND command (see table 181) requests that the device server transfer data from the initiator.Table 181 — SEND commandBitByte7 6 5 4 3 2 1 00 OPERATION CODE (0Ah)1 Reserved AER2 (MSB)3TRANSFER LENGTH4 (LSB)5 CONTROLAn asynchronous event reporting (AER) bit of one indicates that the data to be transferred conforms to AER dataformat as defined in table 182. A SEND command with an AER bit of one shall be only issued to logical unit zero.An AER bit of zero indicates that the data to be transferred are vendor specific.The TRANSFER LENGTH field specifies the length in bytes of data that shall be transferred from the Data-Out Buffer.A transfer length of zero indicates that no data shall be sent. This condition shall not be considered an error.216 dpANS SCSI Primary Commands - 2 (SPC-2)
