VOLUME NUMBER: The VOLUME NUMBER specifies a volume within the Medium Auxiliary Memory. The
number of volumes of the MAM will equal that of the attached multi-volume medium. The mult-volume is not
supported by the drive. If this field is set to non-ZERO, a check condition status is returned with a ILLEGAL
REQUEST sense key.
PARTITION NUMBER: The PARTITION NUMBER specifies a partition within a volume. The number of partitions
of the MAM will equal that of the attached multi-partition medium. The multi partition is not supported by the
drive. If this field is set to non-ZERO, a check condition status is returned with a ILLEGAL REQUEST sense key.
If the combination of VOLUME NUMBER and PARTITION NUMBER is not valid, the command will be terminated
with a CHECK CONDITION status. The sense key will be set to ILLEGAL REQUEST, and the additional sense
data will be set to INVALID FIELD IN CDB.
PARAMETER LIST LENGTH: 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 will not be considered an error. If the parameter list length results in the truncation of an attribute,
the WRITE ATTRIBUTE command will be terminated with a CHECK CONDITION status. The sense key will be set
to ILLEGAL REQUEST and the ASC will be set to PARAMETER LIST LENGTH ERROR.
