•
Detecting a deferred check condition

•
Detecting any error condition that prevents successful completion of an
operation
Good
Good (00) status indicates that the device successfully completed the
command.
Reservation Conflict
Reservation Conflict (18) status is returned whenever a SCSI initiator attempts
an operation that violates another initiator’s Logical Unit Reservation.
