However, if the IDD responds with a BUSY status or QUEUE FULL status due to its not being able to receive the command that was issued, the UNIT ATTENTION condition is not cleared.

The above CHECK CONDITION status response that is the cause of the UNIT ATTENTION condition hold can be prohibited by the specification of the CHANGE DEFINITION command. When the CHECK CONDITION status response is prohibited, the IDD executes the commands it receives normally, except in the case of a RESERVATION CONFLICT status, BUSY status or QUEUE FULL status. In this case, the UNIT ATTENTION condition for the INIT that issued that command is cleared.

See Section 3.1.4 “CHANGE DEFINITION” concerning setting details.

(2)INQUIRY command

The INQUIRY command is executed normally, but the UNIT ATTENTION condition is not cleared.

a.In the case of a Sense Data Hold state

The IDD executes the REQUEST SENSE command normally and sends the sense data which are being held to the INIT. In this case, the UNIT ATTENTION condition is not cleared.

b.In the case of a State other than a Sense Data Hold state
