CHAPTER 6 COMMUNICATION INTERFACE AND COMMAND PROTOCOL

Table 6-2SCSI messages supported by the tape drive (continued)

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 VXA-320 tape drive is available with a wide, High-density (HD) 68-pin, low-voltage differential (LVD) SCSI interface. This section provides general information about the specifications for the tape drive’s Small Computer System Interface (SCSI), including:

SCSI cable requirements

SCSI connector requirements

Terminator requirements

 

 

! Important

Although the tape drive’s High-density, 68-pin LVD SCSI

 

interface is compatible with both single-ended and narrow SCSI

 

buses, to avoid performance issues Tandberg Data does not

 

recommend using the tape drive on either of these buses.
