  • Page 43: Scsi Interface

    5.SCSI Interface 5. SCSI Interface 5.1. Introduction The Sony SDX-800V uses the SCSI interface to connect to the host system. The Small Computer System Interface (SCSI) is an industry standard interface, approved by the American National Standards Institute (ANSI). It is recommended that this document be used along with the ANSI standard document.

  • Page 44: Supported Commands

    5.SCSI Interface Supported Commands 5.1.3. The following commands are supported. They include all Mandatory and Extended commands, most Optional commands.

  • Page 45: Scsi Bus Operation

    5.SCSI Interface 5.2. SCSI Bus Operation 5.2.1. Typical SCSI Operation This example describes the typical SCSI bus sequence between the host and the drive. After waiting for the bus clear time the Host arbitrates for the SCSI bus. It does this by asserting BSY and the data line corresponding to its bus ID.

  • Page 46: Message Specification

    5.SCSI Interface The I/O activity from this point is controlled entirely by the target. The target initiates the COMMAND phase and reads in the Command Descriptor Block (CDB) from the Host. If the Host has sent an Identify message with the Disconnect permission bit set, then the target will immediately disconnect from the bus after the entire CDB has been received.

  • Page 47: Command Complete (00H)

    5.SCSI Interface COMMAND COMPLETE (00h) 5.3.1. This message is sent from a target to an initiator to indicate that the execution of a command or a series of linked commands has completed and valid status has been sent to the initiator. After successfully sending this message, the target goes to the BUS FREE phase by releasing BSY.

  • Page 48: Synchronous Data Transfer Request (01H)

    5.SCSI Interface The TRANSFER WIDTH EXPONENT field defines the transfer width to be used during DATA IN phases, and DATA OUT phases. The transfer width that is established applies to both SCSI devices. Valid transfer widths are 8 bits (m=00h) and 16 bits (m=01h) if all the protocol options bits are zero. The only valid transfer width is 16 bits (m=01h) if any of the protocol options bits are one.

  • Page 50: Wide Data Transfer Request

    5.SCSI Interface The implied synchronous agreement shall remain in effect until a BUS DEVICE RESET message is received, until a hard reset condition occurs, or until one of the two SCSI devices elects to modify the agreement. The default data transfer mode is asynchronous data transfer mode.

  • Page 51: Save Data Pointer (02H)

    5.SCSI Interface Following target response (1) above, the implied agreement for wide data transfers shall be considered to be negated by both the initiator and the target if it the initiator asserts ATN and the first message out is either MESSAGE PARITY ERROR or MESSAGE REJECT.

  • Page 52: Initiator Detected Error (05H)

    5.SCSI Interface INITIATOR DETECTED ERROR (05h) 5.3.6. This message is sent from an initiator to inform a target that an error (e.g.: parity error) has occurred that does not prevent the target from re-trying the operation. At this point, present pointer integrity is not assured. A RESTORE POINTERS message or a disconnect followed by a re-selection, will cause the pointers to be restored to their previously defined state.

  • Page 53: Bus Device Reset (0Ch)

    5.SCSI Interface 5.3.11. BUS DEVICE RESET (0Ch) This message is sent from an initiator to direct a target to clear all current commands. Upon recognizing this message, the currently executing command will be aborted and the drive will proceed to the BUS FREE state. The drive will then execute a hard reset which will leave the drive in a state as if it had been power-cycled.

  • Page 54: Status Specification

    5.SCSI Interface 5.4. Status Specification A Status byte is sent from the drive to the Host during the STATUS phase at the termination of each command as specified in the SCSI specification, unless the command has been cleared by an ABORT message, by a BUS DEVICE RESET message, or by a hard RESET.

  • Page 65 LOAD/UNLOAD 6.Command Specification When the drive receives the UNLOAD, the tape is rewound to BOM and ejected. The operator must reload the drive manually. If, however, the drive has previously received a PREVENT MEDIA REMOVAL (with prevent bit set) command, the tape is retained in the drive. A subsequent LOAD command will load and position the tape at BOP ZERO.
