Table 3-3. Packet Status Codes (cont’d)

CODE	MEANING	NOTES
$1B	TARGET module rejected an initiator message and returned with	2
	this status to a particular LUN service routine.
$1C	TARGET module sent a check status with an "illegal request" sense	2
	block to some initiator because the particular LUN that the
	initiator wanted was not enabled.
$1D	TARGET module sent a busy status to the calling initiator because	2
	the particular LUN that the initiator wanted was already busy
	servicing a command.

	Request-Sense-Data Error-Class 7 Codes
	(Controller-Dependent)
$20	NO SENSE. Indicates that there is no specific sense key	2,3
	information to be reported for the designated logical unit.
$21	RECOVERED ERROR. Indicates that the last command	2,3
	completed successfully with some recovery action performed by
	the TARGET. Details can be determined by examining the
	additional sense bytes and information bytes.
$22	NOT READY. Indicates that the logical unit addressed cannot be	2,3
	accessed. Operator intervention may be required to correct this
	condition.
$23	MEDIUM ERROR. Indicates that the TARGET detected a	2,3
	nonrecoverable error condition that was probably caused by a flaw
	in the medium or an error in recording data.
$24	HARDWARE ERROR. Indicates that the TARGET detected a	2,3
	nonrecoverable hardware failure (for example, controller failure,
	device failure, parity error, etc.) while performing the command or
	during self test.
$25	ILLEGAL REQUEST. Indicates that there was an illegal parameter	2,3
	in the command descriptor block or in the additional parameters
	supplied as data.
