SCSI Command Overview SCSI Command Overview Drive Control Commands Busy 08H A busy status is returned by the target during powerup until all poweron diagnostic tests have been completed. A busy status is also returned when multiple commands are outstanding in the target, and a media access command is received with the DISC PRIV bit cleared in the identify message. Intermediate/Good 10H Unless an error, exception, or abnormal condition causes a Check Condition status or a Reservation Conflict status, the Intermediate Good status is returned for every command in a series of linked commands, excluding the last command. If this status is not returned, the chain of linked commands is broken; no further commands in the series are executed. Intermediate Condition Met 14H This status is the combination of the Condition Met and the Intermediate statuses. Reservation Conflict 18H This status is returned when a SCSI device attempts to access a logical unit that is reserved for another initiator. Queue Full 28H This status is returned when a Simple Queue Tag, Ordered Queue Tag, or a Head of Queue Tag message is received and the command queue of the drive is full. The I/O process is not placed in the command queue. The drive can handle 32 I/O processes at a time. Chapter 1 1-15
