STATUS BYTE
Description
00h
GOOD
The command has been successfully completed.
02h
CHECK CONDITION
An error, exception, or abnormal condition has been detected. The sense data is
set by the drive. The REQUEST SENSE command should be issued to deter-
mine the nature of the condition.
04h
CONDITION MET
This status is returned when an unlinked PRE-FETCH command has been
successfully completed.
08h
BUSY
This condition is returned when disconnect privilege is not granted while the
drive is BUSY processing the other command for the other initiator. The normal
initiator recovery action is to issue the command at a later time or to reissue the
command and grant the disconnect privilege.
10h
INTERMEDIATE
This status is returned for every command except PRE-FETCH command in a
series of linked commands (except the last command), unless the command is
terminated with CHECK CONDITION, RESERVATION CONFLICT, or BUSY
status. If INTERMEDIATE or INTERMEDIATE CONDITION MET status is not
returned, the series of linked commands is terminated and the task is ended.
14h
INTERMEDIATE CONDITION MET
This status is returned when a linked PRE-FETCH command has been
completed, unless the command is terminated with CHECK CONDITION,
RESERVATION CONFLICT, or BUSY status. If INTERMEDIATE or
INTERMEDIATE CONDITION MET status is not returned, the series of linked
commands is terminated and the task is ended.
18h
RESERVATION CONFLICT
This status is returned whenever a SCSI device attempts to access the drive and
it has been reserved by another initiator. See Section 8.29, "Reserve (16)" on
page 155.
