SENSE KEYS

The Sense Keys are described in Table A-1. These are the sense keys returned in byte 2, bits 0-3 of the error code sense formats described in paragraph 8-3.1 on page 8-4.

	Table A-1. Sense Key Descriptions
SENSE KEY	DESCRIPTION
0h	NO SENSE. Indicates there is no specific sense key information to be reported for the designated log-
	ical unit. This sense key indicates a successful command or a command that received a CHECK CON-
	DITION status because a filemark, EOM, or ILI bits is set.
1h	RECOVERED ERROR. Indicates the last command completed successfully with some recovery
	action performed by the target. Details are obtained by examining the additional sense bytes and the
	information bytes.
2h	NOT READY. Indicates the logical unit addressed cannot be accessed. Operator intervention may be
	required to correct this condition.
3h	MEDIUM ERROR. Indicates the command terminated with a nonrecoverable error condition that was
	probably caused by a flaw in the medium or an error in the recorded data. This sense key may also be
	returned if the target is unable to distinguish between a flaw in the medium and a specific hardware fail-
	ure.
4h	HARDWARE ERROR. Indicates the target detected a nonrecoverable hardware failure (for example,
	controller failure, device failure, parity error, etc.) while performing the command or during a self test.
5h	ILLEGAL REQUEST. Indicates there was an illegal parameter in the command descriptor block or in
	the additional parameters supplied as data for some commands (FORMAT UNIT, SEARCH DATA,
	etc.). If the target detects an invalid parameter in the command descriptor block, the target terminates
	the command without altering the medium.
6h	UNIT ATTENTION. Indicates the removable medium may have been changed or the target has been
	reset.
7h	DATA PROTECT. Indicates a command that writes the medium was attempted on a device that is pro-
	tected from this operation. The write operation is not performed.
8h	BLANK CHECK. Indicates the device encountered blank medium indication while reading.
Ah	COPY ABORTED. Indicates a COPY command was aborted due to an error condition on the source
	device, the destination device, or both.
Bh	ABORTED COMMAND. Indicates the target aborted the command. The initiator may be able to
	recover by trying the command again.
Dh	VOLUME OVERFLOW. Indicates EOM was reached and data remains in the buffer that has not been
	written to the medium. A RECOVER BUFFERED DATA command(s) may be issued to read the
	unwritten data from the buffer.
