The VOLUME NUMBER specifies a volume within the Medium Auxiliary Memory. The number of volumes of the
MAM shall equal that of the attached multi-volume medium. If the medium only has a single volume, then this field
shall be set to zero.
The PARTITION NUMBER specifies a partition within a volume. The number of partitions of the MAM shall equal
that of the attached multi-partition medium. If the medium only has a single partition, then this field shall be set to
zero.
If the combination of VOLUME NUMBER and PARTITION NUMBER is not valid, the command shall be terminated
with a CHECK CONDITION status. The sense key shall be set to ILLEGAL REQUEST, and the additional sense
data shall be set to INVALID FIELD IN CDB.
The PARAMETER LIST LENGTH field specifies the length in bytes of the parameter list contained in the DATA-OUT
Buffer. A parameter list length of zero indicates that no parameter data is present; this shall not be considered an
error. If the parameter list length results in the truncation of an attribute, the WRITE ATTRIBUTE command shall be
terminated with a CHECK CONDITION status. The sense key shall be set to ILLEGAL REQUEST and the additional
sense code shall be set to PARAMETER LIST LENGTH ERROR.
