The Parameter Code is set to 0004h.
The Disable Update (DU) bit will always be set to 0 to
indicate that the Drive is always free to update the
counter.
(Note: This bit can not be changed by the initiator)
The Disable Save (DS) bit is set to 1 to indicate that the
Drive does not support saving of this log parameter.
(Note: This bit can not be changed by the initiator)
The Target Save Disable (TSD) bit is set to 1 to indicate
that the Drive does not provide any Drive-defined method
for saving of this log parameter.
(Note: This bit can not be changed by the initiator)
The Enable Threshold (ETC) bit is set to 0 to indicate that
no threshold comparison will take place.
The Threshold Met Criteria (TMC) field is valid only if the
ETC bit is set to 1 and it selects one of four possible
Threshold Met Criteria.
The default value is 11b. See the LOG SELECT command for
further description.
The List Parameters (LP) bit is set to 0 to indicate that
the parameter is a data counter.
(Note: This bit can not be changed by the initiator)
This field is set to 04h to indicate that the counter is 4
bytes wide.
This counter presents an estimation of the maximum capacity
of the current partition. This counter corresponds to the
value of the Partition Size Descriptor of Active Partition
in Mode Sense's - Medium Partition Page, but the count here
is scaled to kilobytes.
Any attempt by the Initiator to alter this counters
accumulated, threshold or control-bytes value will be
ignored.
(Note: The Current Partition number can be obtained from
MODE SENSE - Device Configuration Page - see field Active
Partition. The Number of additional partitions on the
currently inserted tape can be obtained from MODE SENSE -
Medium Partition Page - see field Additional Partitions
Defined.)
