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)

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."
