SCSI Command Overview Optical Drive Control Through SCSI Optical Drive Control Through SCSI The optical drive can be controlled by the commands described in this document. This SCSI command set complies with ANSI X3.131-1994 standards. The role of the host computer and the target or the address of a disk is defined in the SCSI specifications as follows: Initiator The initiator, usually the host, issues the drive control commands.
PAGE 22
Drive Control Commands This section describes all specifications, except command specifications of the target. The “SCSI Commands Used by the Target” are described later in this chapter. SCSI Bus Phases The target supports the following phases specified in the SCSI standard. Arbitration phase When the drive tries to reconnect to an initiator to continue command operations, it waits for the BUS FREE phase, then enters the ARBITRATION phase.
PAGE 23
SCSI Command Overview Drive Control Commands Data phase The data phase encompasses both the “data in” phase and the “data out” phase to transfer data to and from the drive. Synchronous and asynchronous data transfers are supported. The data in phase allows the target to request that data be sent to the initiator from the target. The data out phase allows the target to request that data be sent from the initiator to the target.
PAGE 24
Table 1-1 Target-Supported Messages Code (hex.
PAGE 25
SCSI Command Overview Drive Control Commands Command Complete 00H This message is sent from the target to the initiator to indicate that the execution of a command has terminated and that valid status has been sent to the initiator. After successfully sending this message, the target goes to the Bus Free Phase by releasing BSY (Busy). Extended Message 01H This message is sent from either the initiator or the drive to indicate that the message is an extended message.
PAGE 26
The transfer period is the minimum time allowed between leading edges of successive REQ pulses and of successive ACK pulses. The REQ/ACK offset is the maximum number of REQ pulses allowed to be outstanding before the leading edge of its corresponding ACK pulse is received at the target. This value prevents overflow conditions in the device’s reception buffer and offset counter. A REQ/ACK offset value of zero indicates asynchronous mode.

Table 1-4 Offset Values (For 5.2 and 9.1 Gbyte Drives) Initiator Requested (REQ/ACK Offset) Drive Response (REQ/ACK Offset) 0 <= xi <= 15 xt = xi xt 0 <= xi <= 255 xt = 15 15 Save Data Pointer 02H This message is sent from the target to direct the initiator to save a copy of the present active data pointer for the currently attached logical unit. The drive may issue this message when it disconnects from the SCSI Bus during data transfer.
PAGE 29
SCSI Command Overview Drive Control Commands Message Reject 07H This message is sent from either the initiator or the target to indicate that the last message was inappropriate or has not been implemented. When the target receives a MESSAGE REJECT message from the initiator, it takes the following action based on which message was rejected. Command Complete The target goes to Bus Free Phase and does not consider this as an error.
PAGE 30
No Operation 08H This message is ignored by the target. Message Parity Error 09H When the target receives this message, it retries the operation by resending the original message once. If the message cannot be sent successfully, the target immediately goes to the Bus Free Phase and aborts the current SCSI command. No further reconnection is attempted and no status or COMMAND COMPLETE message is returned for the command.
PAGE 31
SCSI Command Overview Drive Control Commands Clear Queue 0EH The drive goes to the BUS FREE phase following successful receipt of the CLEAR QUEUE message. The drive clears all I/O processes, from all initiators, in the queue for the specified logical unit from the queue. All active I/O processes are terminated. The medium may have been altered by partially executed commands. All pending status and data for that logical unit for all initiators are cleared.
PAGE 32
Table 1-6 Head of Queue Tag Byte 7 6 5 4 3 0 Message Code (21H) 1 Queue Tag (00H-FFH) 2 1 0 The Head of Queue Tag message specifies that the I/O process be placed first in the logical unit's command queue. When the drive receives a subsequent I/O process received with a Head of Queue Tag message, the I/O process that has been already done is not interrupted.
PAGE 33
SCSI Command Overview Drive Control Commands Bit 2-0 These bits specify a logical unit number. Only one logical unit number is identified for any one selection sequence. Status Phase A status byte is sent from the target to the initiator during the Status Phase at the termination of each command unless the command is cleared by an ABORT message, a BUS DEVICE RESET message, or a RESET condition. The target supports the following status codes. Table 1-8 Target-Supported Status Codes Code (hex.
PAGE 34
Busy 08H A busy status is returned by the target during powerup until all poweron diagnostic tests have been completed. A busy status is also returned when multiple commands are outstanding in the target, and a media access command is received with the DISC PRIV bit cleared in the identify message.
PAGE 35
SCSI Command Overview Drive Control Commands Conditions Attention Condition The Attention Condition allows an initiator to inform the target that the initiator has a message ready. The target gets this message at its convenience by performing a Message Out Phase as follows: 1. If the ATN signal becomes true during a COMMAND phase, the drive enters the MESSAGE OUT phase after transferring part or all of the command descriptor block bytes. 2.
PAGE 36
Unit Attention Condition A unit attention condition for a logical unit begins for each initiator for any of the following conditions: • Poweron or Reset • Disk Loaded • Micro Code Change • Inquiry Data Change • Mode Select Data Change The unit attention condition persists for each initiator until that initiator issues a command to the logical unit other than Request Sense or Inquiry for which the target reports a CHECK CONDITION status.
PAGE 37

Entries are arranged in order of operation code. Each entry includes: 1. Command name 2. Operation code 3. Brief description of the command 4. Command descriptor block (CDB) 5.

SCSI-2 Drive Command Set Numerical List of Commands Flag, Link, and RelAdr A Link bit of 1 indicates that the drive links to the next command upon successful completion of the current command. When the command is terminated successfully, the drive returns the INTERMEDIATE/GOOD status and the LINKED COMMAND COMPLETE or the LINKED COMMAND COMPLETE (WITH FLAG) message depending on the state of the Flag bit. The Flag bit may be set to 1 only when the Link bit is 1.
PAGE 45
SCSI-2 Drive Command Set Test Unit Ready Command (00H) Test Unit Ready Command (00H) This command determines the READY state of a drive. If the drive is in a READY state when it receives this command, it returns a GOOD status. A drive is in the READY state when the optical disk is loaded and spun up, and a read or write operation could successfully complete. If the drive is not ready when it receives this command, it returns a CHECK CONDITION with a sense key of NOT READY.
PAGE 46
SCSI-2 Drive Command Set Rezero Unit Command (01H) The Rezero Unit Command is identical to the Test Unit Ready Command (see the previous page).
PAGE 47
SCSI-2 Drive Command Set Request Sense Command (03H) Request Sense Command (03H) This command determines the specific error condition when a drive fails to complete a command and returns a CHECK CONDITION status. Sense data is preserved for the initiator until retrieved by a Request Sense Command or until the same drive receives another command. Internal Error Codes are used to represent the error condition and can be used to determine what type of error recovery procedure is appropriate.

Disconnect Timeout Settings Disconnect Timeout Settings Disconnect Timeout Settings The following commands will cause a SCSI disconnect. It is useful to know what the maximum times for disconnect are so driver timeouts can be set appropriately. NOTE In Table E-1 the maximum disconnect time is represented by the nominal number of seconds plus the number of levels of error recovery times 60. You can see the maximum time can be very long.
PAGE 372
Disconnect Timeout Settings Disconnect Timeout Settings a. If the Read Element Status Command disconnects, it will perform movements identical to that of the Initialize Element Status before sending the element status data. Therefore, the timeout should be set the same as the Initialize Element Status command. b. The Send Diagnostic Command is different from the other commands in that there are a number of different tests that may be executed. Also, the test may be run in a loop.
