Thanks for the reply. Now just to make sure I understand...

So it would be valid for an SCC device to return in the LUN list logical
unit numbers that follow the SCC addressing methods. For example, when a
REPORT LUNS command is sent to the base address of the SCC device one of
the LUN reported in the LUN list may be:
0x40 0x03 0x00 0x00 0x00 0x00 0x00 0x00
This would be the logical unit number for volume 3. Correct?
