Page 193: Scsi Message System
10.0 SCSI Message System This chapter describes how the message system is implemented on the drive. Included is a functional description of the supported messages. 10.1 Supported Messages The messages supported by the drive are listed in the figure below. Negate ATN MESSAGE CODE (hex)
Page 194: Task Complete (00H)
If an unsupported message is received, the drive will send the MESSAGE REJECT message to the initi- ator. If at the time the unsupported message is received a valid nexus exists, the drive will continue with the command. If no valid nexus exists, the drive will go to BUS FREE. 10.1.1 TASK COMPLETE (00h) The drive sends this message to the initiator to indicate that the execution of a command has been termi- nated and that valid status has been sent to the initiator.

Page 196: Figure 181. Target Response To Initiator's Transfer Period (Lvd Mode)
10.1.2.2 Synchronous Negotiation started by the drive If the drive recognizes that negotiation is required, it sends a SDR message to the initiator with minimum transfer period on the current receiver mode. The drive interprets the initiator corresponding transfer period as shown in the figure below. LVD mode Initiator Request Target Transfer Period (ns)
Page 197: Wide Data Transfer Request (010203H)
10.1.3 WIDE DATA TRANSFER REQUEST (010203H) A pair of WIDE DATA TRANSFER REQUEST messages is exchanged between an initiator and a drive to establish a data transfer width agreement between the two devices. The initiator may initiate a wide data transfer negotiation at any time after the LUN has been identified.
Page 198: Figure 185. Target Request To Initiator
transfer width agreement is reinstated if the drive successfully retransmits the WIDE DATA TRANSFER REQUEST message to the Initiator. For any other message the drive completes negotiation and goes to the negotiated data transfer width. 10.1.3.2 Transfer Width Negotiation started by the drive If the drive recognizes that negotiation is required, it sends a WIDE DATA TRANSFER REQUEST mes- sage to the Initiator with the transfer width exponent equal to 1 (E = 01h).

Page 202: Abort (06H)
10.1.9 ABORT (06h) This message is sent from the initiator to direct the drive to clear the present operation for this initiator and logical unit including queued command(s). If a logical unit has been identified, then all pending data and status for the issuing initiator and this logical unit will be cleared and the drive will go to the BUS FREE phase.
Page 203: Linked Command Complete With Flag (0Bh)
10.1.14 LINKED COMMAND COMPLETE WITH FLAG (0Bh) The drive sends this message to the initiator to indicate that the execution of a linked command with flag bit set to one has completed and that valid status has been sent to the initiator. After successfully sending this message, the drive goes to COMMAND phase to receive the next command.
Page 204: Ignore Wide Residue (2301H)
10.1.18.2 HEAD OF QUEUE (21xxh) Commands with this tag should be inserted into the head of the queue. When a command is being executed, this tagged command will be inserted to the head of queue to be executed after the command being currently executed.

10.2 Supported Message Functions The implementation of the supported messages will also include the following functions. ! Retry SCSI Command or STATUS phase The retry will be caused by the following error condition. - The drive detected SCSI bus parity error (COMMAND phase) - The drive receives INITIATOR DETECTED ERROR MESSAGE during or at the conclusion of an information transfer phase (Command Data Out or Status Phase) Note: The initiator may send the INITIATOR DETECTED ERROR message as a result of an initiator...
Page 206: Attention Condition
10.3 Attention Condition The attention condition allows an initiator to inform the drive that a MESSAGE OUT phase is desired. The initiator may create the attention condition by asserting the ATN signal at any time except during the ARBITRATION or BUS FREE phases. The initiator must create the attention condition by asserting the ATN signal at least two deskew delays before releasing ACK for the last byte transferred in a bus phase to guarantee that the attention condition will be honored before transition to a new bus phase.
Page 207: Scsi Bus Related Error Handling Protocol
10.4 SCSI Bus Related Error Handling Protocol This protocol is used to handle errors that threaten the integrity of a connection between the Target and an initiator. 10.4.1 Unexpected BUS FREE Phase Error Condition There are several error conditions that will cause the drive to immediately change to the BUS FREE phase regardless of the state of the ATN signal.
Page 208: Initiator Detected Error Message
10.4.6 INITIATOR DETECTED ERROR Message An INITIATOR DETECTED ERROR message is valid after a COMMAND, DATA IN/OUT or STATUS phase has occurred. If another phase has occurred, the message is rejected. Depending on the model, the drive will optionally retry the previous phase if it is command or status. If this fails or the previous phase was a data transfer the drive will generate a CHECK CONDITION status and a Sense key of ABORTED COMMAND with additional sense code of INITIATOR DETECTED ERROR.
Page 209: Additional Information
11.0 Additional information This chapter provides additional information or descriptions of various functions, features, or operating models supported by the Target that are not fully described in previous chapters. 11.1 SCSI Protocol There are various operating conditions that prevent the Target from executing a SCSI command. This section describes each of these operating conditions and their relative priority.

Page 212: Unit Attention Condition
11.1.5 Unit Attention Condition The drive will generate a unit attention condition for each initiator under the following conditions: The drive has been reset. This includes Power On Reset, SCSI Bus Reset, and TARGET RESET message. The transceiver mode has been changed. The mode parameters in effect for this initiator have been changed by another initiator.
Page 213: Command Processing During Startup And Format Operations
11.1.6 Command Processing During Startup and Format Operations If the drive receives a command from an Initiator while it is executing a startup or format operation, the response of the drive varies with the command as follows: INQUIRY The drive sends INQUIRY data and returns appropriate status. REPORT LUNS Same as above.

Page 223: Write Cache
11.7 Write Cache If WCE (Mode Page 8) is set to one, the drive returns GOOD status and TASK COMPLETE message and goes to BUS FREE immediately after receiving the data of the last sector before actually writing the data onto the media.
Page 224: Segmented Caching
11.9 Segmented Caching Segmented Caching divides the data buffer into several buffer segments. Size and number of segments are determined by Number of Cache Segments, Cache Segment Size, SIZE and LBCSS (Mode Page 8). Number of Segments can be 1 through 255. (256 segments can be used by specifying segment size.) The Read Ahead is a function that read data that the initiator has not yet requested to the buffer segment.
Page 225: Multiple Initiator Environment
11.14 Multiple Initiator Environment 11.14.1 Initiator Sense Data Separate sense data is reserved for each I_T_L nexus and I_T_L_Q nexus. Each sense data is main- tained independent of commands from other initiators. 11.14.2 Initiator Mode Select/Mode Sense Parameters A single shared copy of the Mode Select/Mode Sense parameters is maintained by the drive. This includes both the current and saved parameters.
Page 226: Reset
11.16 Reset The Reset condition is used to clear all SCSI devices from the bus. This condition takes precedence over all other phases and conditions. After a reset condition is detected and the reset actions are completed, the drive returns to a 'SCSI bus enabled' state that allows the drive to accept SCSI commands. This device uses the Hard reset option as defined in the SCSI-3 Parallel Interface Standard.
Page 227: Scsi Bus Reset And Target Reset Message
11.16.3 SCSI Bus Reset and TARGET RESET Message These two reset conditions cause the following to be performed. ! If reset goes active while the power-up sequence is in progress, the power-up sequence is started over. ! If the Auto Spin up is enabled and the bring-up operation has not been completed, the bring-up operation will be re-attempted from the beginning.
Page 228: Diagnostics
11.17 Diagnostics The drive will execute the bring-up operation at POR to assure the correct operation of the drive by validating components (ROM, RAM, Sector Buffer, EEPROM, HDC, Spindle Motor, Actuator), checking stored information in the reserved area and EEPROM, and verifying fault detects circuits. Self-test can be invoked by a SEND DIAGNOSTIC command.
