The REPORT LUNS command requests that the peripheral device logical unit numbers of known logical units in the
target be sent to the application client. The REPORT LUNS command shall return information about only those logical
units to which commands may be sent. The REPORT LUNS command shall not be affected by reservations or persis-
tent reservations.
The Allocation length shall be at least 16 bytes. If the Allocation length is less than 16 bytes, the device server shall
return CHECK CONDITION status. The sense key shall be set to ILLEGAL REQUEST and the additional sense data
shall be sent to INVALID FIELD IN CDB.
The Allocation length is not sufficient to contain the logical unit number values for all configured logical units, the
device server shall report as many logical unit number values as will fit in the specified Allocation length. This shall not
be considered an error.
The device server shall report the logical unit numbers of configured logical units using the format shown in table xxx.

descriptor block is too small to transfer information about all configured logical units, the LUN list length value shall
not be adjusted to reflect the truncation.
