Request Sense
The following table provides the additional sense codes (ASCs)
and additional sense code qualifiers (ASCQs) that may be
reported. Additional information, explanations, or suggestions for
action are included in some of the descriptions.
Sense Key Description
0h NO SENSE.
1h RECOVERED ERROR. This can be caused by rounding of Mode Parameters
on a MODE SELECT, or may report that recovery algorithms were required
to complete a move operation. The device may still be able to continue to
function without any unrecovered errors for a long period of time, however.
2h NOT READY. The media changer is not ready for move operation
commands. Initialization or calibration may be in-progress or may have
failed.
4h HARDWARE ERROR. The Additional Sense Code / Additional Sense Code
Qualifier fields may present more specific information.
5h ILLEGAL REQUEST. The Command Descriptor Block or supplied parameter
data had an unsupported or illegal operation specified. Check bytes 15, 16,
and 17.
6h UNIT ATTENTION. Unit Attentions are created after a device reset, if the
medium asynchronously becomes ready to the initiator, if another initiator
changes Mode Parameters, and/or if the firmware is updated.
Bh COMMAND ABORTED. This key is generated when a command has been
aborted by the media changer for some reason. Check the Additional Sense
Code / Additional Sense Code Qualifier bytes.
