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.

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

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

x  An unrecoverable error was detected on the SCSI bus.

x  An 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.

x  Applicability 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.
