Fujitsu MBC2073RC Additional Sense Code, Common Command Set CCS, Initiator Init, Sense Data

Glossary

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.

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.

Common Command Set (CCS)

SCSI standard logical specifications established by a working group of the American National Standard Institute (ANSI). Requirements and features for supported direct-access devices (e.g., hard disk devices) are stipulated with the CCS.

Initiator (INIT)

This is a FC device which initiates input and output operations on the FC bus. In this manual, initiator has been abbreviated to "INIT."

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.

Small Computer System Interface (SCSI)

Input/output interface standardized by the American National Standard Institute (ANSI)

[Specification Number: ANSI X3.131-1986]

Status

This is 1 byte of information reported to the initiator by the target device when execution of each command is completed, which displays the command's completion state.

Target (TARG)

This is the FC device that executes the input/output operations initiated by the initiator (INIT). In this manual, target is abbreviated "TARG."
