The tape library keeps all element status current and valid by performing an automatic inventory operation as required. Therefore, the Initialize Element Status command is allowed and ignored (the library returns GOOD status without performing another inventory). To re-inventory specific elements as part of application error handling, go to the section about the SCSI command Initialize Element Status with Range - X'E7'.
