After sending REPORT_LUNS wasn't successful, kernel will call scsi_sequential_lun_scan function scans from LUN 1. It means that driver need reprobe ATAPI port. Meanwhile, the driver can not indicate which LUN num need to be assigned. As a result, system will get all invalid LUNs if reprobing for device is OK.
So I think that I can reject multi-LUNs for SATA devices in the slave_alloc function.
