This command transfers the information showing the IDD's characteristics (INQUIRY data) to the application client. This command is executed immediately without queuing in a system which issues only commands with no tags or links.

This command is executed normally even in cases where the UNIT ATTENTION condition is held, and the UNIT ATTENTION condition is not cleared. This command is also executed normally when the disk drive is not in the ready state or even when an illegal logical unit number (LUN) is specified.

A CHECK CONDITION status is reported for this command and it is terminated abnormally only in the case that one of the following conditions is detected.

ξThere is an error in the specifications other than the LUN field of the CDB.

ξIt is impossible to send INQUIRY data because of an IDD hardware error.

ξAn unrecoverable error was detected on the SCSI bus.

ξAn error detected during command execution was recovered in the IDD's error recovery processing (Retry), but the mode which reports "RECOVERED ERROR" is specified in the MODE SELECT parameter.

ξApplicability to overlapping command exception conditions (See Section 1.7.1.)

The functions which can be specified in this command's CDB and the contents of information transferred to the application client from the IDD differ depending on the specifications in the CHANGE DEFINITION command. Furthermore, see Section 3.1.4, "CHANGE DEFINITION (40)" concerning the CHANGE DEFINITION command.
