Status Phase

A status byte is sent from the target to the initiator during the Status
Phase at the termination of each command unless the command is
cleared by an ABORT message, a BUS DEVICE RESET message, or a
RESET condition. The target supports the following status codes.
Target-Supported Status Codes
Code (hex.) Status
00H Good
02H Check Condition
04H Condition Met
08H Busy
10H Intermediate/Good
14H Intermediate Condition Met
18H Reservation Conflict
28H Queue Full
Good 00H
This status indicates that the target has successfully completed the
command.
Check Condition 02H
Any error, exception, or abnormal condition that causes sense data to be
set causes a Check Condition status. The Request Sense Command
should be issued following a CHECK CONDITION status to determine
the nature of the condition.
Condition Met 04H
This status or Intermediate-Condition Met is returned when the Pre-
Fetch command is satisfied.
