Appendix B General Commands 203
Note In addition to the device LUNs, controller LUNs also appear in
the report. Controller LUN values appear at the end of the list.
The host software must use the Inquiry command in order to
differentiate controller LUNs from other storage device LUNs.
Controller LUN Inquiries will report a peripheral device type of
0x0c.
Note The controller LUN at LUN 0x7f may not be reported in response
to a Report LUNs command but the host software may discover
this LUN if it does an Inquiry at LUN 0x7f.
