SPC says that all devices reporting compliance with this standard (as the inquiry data for this device claims) shall support REPORT LUNS. On the other hand, MMC doesn't list REPORT LUNS in its table of mandatory commands. I'm starting to think that even if they report a SCSI compliance level of 3 or greater, we still shouldn't send REPORT LUNS to devices that return MMC type unless we have a white list override.
