Additional Sense Code

This is a 1-byte code displayed in the sense data and is information which specifies the type of error that was detected.

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.

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."

SAS Device

The general name given to a device which is connected to the SAS bus (input/output device, I/O controller, host adapter, expander, etc.).

SCSI

Small Computer System Interface

The standardized input/output interface of the American National Standards Institute (ANSI). [Standard No.: ANSI X3. 131-1986]

Sense Data

When several items of error information are included in a command's completion status, this is information generated by the target for reporting detailed information on that status.

Sense Key

This is a 4-bit code displayed in the sense data. It contains information for classifying the type of error that was detected.

Status
