The Linux SCSI programming HOWTO: Additional sense codes and additional sense code qualifiers

## 22. Additional sense codes and additional sense code qualifiers

When the status of the executed SCSI command is CHECK_CONDITION, sense data is available in the sense buffer. The additional sense code and additional sense code qualifier are contained in that buffer.

From the SCSI-2 specification I include two tables. The first is in lexical, the second in numerical order.

## 22.1 ASC and ASCQ in lexical order

The following table list gives a list of descriptions and device types they apply to.
