Status Codes | Maxtor 10K III manual

SCSI Description

SCSI message-level errors are communicated by messages that are defined specifically for that purpose. SCSI command-level errors are communicated by a status that is returned by the drive during the STATUS phase. This phase occurs at the end of each command, unless the command is terminated by one of the following events:

•ABORT TASK SET message

•ABORT TASK message

•TARGET RESET message

•CLEAR QUEUE message

•Unexpected disconnect

The status code is contained in bits 1 through 5 of the status byte. Bits 0, 6, and 7 are reserved. Table 5-6describes the status codes returned by the drive.

			Status Codes


	00h	GOOD	The drive successfully completed the command.

	02h	CHECK CONDITION	An Auto Contingent Allegiance (ACA) condition occurred.

			The drive cannot service the command at the moment, and
			its Command Descriptor Block has been discarded. The ini-
			tiator can retry the command at a later time. This status is
			returned when:
	08h	BUSY

			This status is returned for every command (except the last)
			in a series of linked		that was successfully		-
			pleted. However, if the		is terminated with other
	10h	INTERMEDIATE	thatcommandGOODtaggedstatusandcommands(such as CHECK CONDITION,thecommandsRESERVA--
			TION CONFLICT, OR BUSY), the INTERMEDIATE status is
			not returned	the series of linked commands			the
			task is ended.

	18h	RESERVATION CONFLICT	Another initiator has reserved drive. (This status is nev-
