This command changes the IDD's SCSI level and the operation mode.
The INIT can know the SCSI level and operation mode that the IDD is currently using by the
INQUIRY command (Standard Inquiry Data and VPD Information - Operation Mode Page: Page
code X 'C0').
If the "Save" bit of CDB byte 2 specifies "1," the IDD saves the SCSI level and operation mode
specified in this command in the Boot-ROM (Flash ROM) when the command is executed.
If this bit specifies "0," the changes are not saved.
