Additional sense codes—actions to take

These tables provide information about sense data, so that software can know which additional sense codes can be reported under which sense keys. It is important that the operating system makes all Request Sense data available to applications and, in interpreted form, to the end-user.

Actions are suggested for software to use when determining the recovery action for different sense keys and additional sense code and qualifying codes (ASC/ASCQ).

It is strongly recommended that the operating system and/or application use the entire ASC/ASCQ data to determine the appropriate recovery action.

The tables are in numerical order, not order of priority. That is, they do not suggest which sense keys should be checked first, nor do they recommend priorities for the devices to report errors.

NOTE: When the sense, additional sense code and qualifying sense keys are listed, the software may look at all three keys to determine action. The drive should use that exact combination to report that particular error.

For example, a drive will report that it is not ready when there is no cartridge present by setting the sense key to NOT READY with additional sense of 0402h (LUN not ready, initializing command required). No other combination of sense key and additional sense may be used to report that particular condition.
