Arbitration phase — an essential phase in a multi-host environment with multiple initiators. In this phase, multiple initiators compete for control of the bus. Only one initiator can have control of the bus at a time. The initiator asserts the BSY signal, simultaneously this initiator outputs its own SCSI ID bit to the SCSI bus. The initiator with the highest SCSI ID will win the arbitration and assert the SEL (select) signal. If the initiator does not win the arbitration, it will revert to the Bus Free phase.

Selection phase — software connections are established between an initiator and a target device. The initiator selects the target device by asserting the ID bit of the selected device and its own ID bit. The initiator then de-asserts the BSY signal, selecting the target device.

Command phase — the initiator issues a command to the target device. Commands are transmitted in a fixed format of 6, 8, or 10 consecutive bytes. Each command is distinguished by a unique op code.

Data phase — data will be exchanged between the initiator and the target device after the specific commands are executed.

There are two types of data phases:

Data-In, where the data is transmitted from the target device to the initiator, or

Data-Out, where the data is transmitted from the initiator to the target device.

Status phase — a status code is returned from the target to the initiator indicating the status in which the command terminated. Occasionally, the system enters the Status phase from the Command phase. Refer to the section entitled, “SCSI status responses” later in this chapter.

Message phase — messages will be exchanged between the initiator and the target device. A message is transmitted from the target device to the initiator, indicating the completion of a command. Refer to the section entitled, “SCSI message responses” later in this chapter.
