The "LUN List Length" field shall contain the length in bytes of the LUN list that
is available to be transferred. The "LUN list length" is the number of logical unit
numbers in the logical unit inventory multiplied by eight. If the allocation length
in the command descriptor block is too small to transfer information about the
entire logical unit inventory, the LUN list length value shall not be adjusted to
reflect the truncation.
The HDD only reports LUN=0 because it has only one LUN.
