(2) FC-4 Device Data

Exchanges consist of two or more frame sequences between the initiator and the

target.

Exchanges starts from command frame by the initiator and ends at response frame

by the target.

Four FC-4 Device Data (FCP_CMND_IU, FCP_DATA_RDY_IU,

FCP_DATA_IU, FCP_RSP_IU) are used to implement SCSI protocol. Figure 1.7

explains the examples of Exchanges in case of SCSI write/read operation.
