Figure 72 LUN Reporting
Parameter List
The LUN List Length field contains the length in bytes of the LUN list that
can be transferred. The
LUN List Length equals the number of logical unit
numbers reported multiplied by eight. If the allocation length in the
CDB
is too small to allow transfer of information about all of the logical units
configured, the
LUN List Length value is not adjusted to reflect the
truncation.
