Glossary

Bus Condition

This is an asynchronous condition for changing the status transition on the SCSI bus.

 

There are two types, the ATTENTION condition and the RESET condition.

Bus Phase

This is the name given to the SCSI bus state. The SCSI bus is in one state or another,

 

the BUS FREE phase, the ARBITRATION phase, the SELECT phase, the

 

RESELECTION phase or the INFORMATION TRANSFER phase. In addition, the

 

INFORMATION TRANSFER phase is subdivided into the DATA IN, DATA OUT,

 

COMMAND, STATUS, MESSAGE AND MESSAGE OUT phases in accordance

 

with the type of information being transferred in the INFORMATION TRANSFER

 

phase.

CCS

Common Command Set

 

This is the standard form of SCSI logical specifications stipulated by the operations

 

subcommittee of the American National Standards Institute (ANSI) which stipulates

 

functions which a direct access device (magnetic disk, etc.) should support.

CDB

Command Descriptor Block

 

A series of data which describes commands related to input/output operations, sent

 

from the initiator to the target.

Command

This is a command to a target to perform an input/output operation, and it is

 

described as the CDB.

Disconnect

This is processing which temporarily frees the connected state of the target with the

 

SCSI bus and the initiator at the point in the target's command processing execution

 

process when operations on the SCSI bus are not needed.

Initiator (INIT)

This is a SCSI device which initiates input and output operations on the SCSI bus. In

 

this manual, initiator has been abbreviated to "INIT."

Logical Unit

This is the device unit which is the object of input/output operations on the SCSI bus.

LUN

Logical Unit Number

 

This is the serial number which identifies a logical unit.

Message

This is control information that is delivered and received between the initiators and

 

targets operating on the SCSI bus for controlling a series of bus phases and

 

input/output operation execution sequences.

Reconnect

For a target which has executed disconnect processing, this is processing which

 

reconnects tot he initiator at the point when operations on the SCSI bus again become

 

necessary.

SCSI

Small Computer System Interface

 

The standardized input/output interface of the American National Standards Institute

 

(ANSI). [Standard No.: ANSI X3. 131-1986]
