Chapter 3 Media Changer Commands
Request Sense Command (03h)
152
Quantum ATL SuperLoader Software Interface Guide
The sense data is valid for a CHECK CONDITION or
RESERVATION CONFLICT status returned on the previous
command. The sense data bytes are preserved by the media
changer until retrieved by a REQUEST SENSE command, or until
the receipt of any other command from the same initiator, though
some commands, such as INQUIRY, do not change sense data.
If the media changer receives an unsolicited REQUEST SENSE, it
returns sense data with the appropriate values in the Sense Key,
Additional Sense Code, and Additional Sense Code Qualifier.
The following illustration portrays the format of REQUEST SENSE
DATA.
