CHAPTER 6 COMMUNICATION INTERFACE AND COMMAND PROTOCOL
Table
Message | Hex | Description | |
Code | |||

|
|
| |
Abort Task | 06h | The initiator is clearing the present and any pending operation for that initiator. | |
Set |
| When the tape drive accepts this message, it releases the bus into the Bus Free | |
|
| phase. | |
|
|
| |
Message | 07h | Either the initiator or the tape drive is indicating that the last message received was | |
Reject |
| inappropriate or not implemented. | |
|
|
| |
No | 08h | The initiator informs the tape drive that it does not have a valid message to send | |
Operation |
| in response to the tape drive’s request for a message. | |
|
|
| |
Message | 09h | The initiator informs the tape drive that one or more bytes in the last message it | |
Parity Error |
| received had a parity error. | |
|
|
| |
Target Reset | 0Ch | The initiator instructs the tape drive to reset all of its current I/O operations. The | |
|
| tape drive releases the SCSI bus into the Bus Free phase, with no operations | |
|
| pending for any initiator, and performs a reset. (See page 24 for more information | |
|
| about resetting the tape drive.) | |
|
|
| |
Ignore Wide | 23h | The tape drive sends the Ignore Wide Residue message to indicate that the | |
Residue |
| number of valid bytes sent was less than the negotiated transfer width. | |
|
|
| |
Identify | 80h | This message is used to establish a physical path connection between the initiator | |
| or | and the tape drive. It also indicates whether disconnect is supported and the LUN | |
| C0h | for which the command is intended. The tape drive supports a LUN of 0. | |

SCSI INTERFACE REQUIREMENTS
The
SCSI cable requirements
SCSI connector requirements
Terminator requirements
|
|
! Important | Although the tape drive’s |
| interface is compatible with both |
| buses, to avoid performance issues Tandberg Data does not |
| recommend using the tape drive on either of these buses. |
