The Parameter Code is set to 0003h.
The Disable Update (DU) bit will normally be set to 0 to
indicate that the Drive is always free to update the
counter. If the counter reaches its maximum value
(FFFFFFFFh) the DU bit is set to 1 and cause the counter
to retain its maximum value.
(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
in response to a LOG SELECT or LOG SENSE command with an
SP bit of 1.
(Note: This bit can not be changed by the initiator)
The Target Save Disable (TSD) bit is set to 0. The Drive
will save this log parameter on the medium each time the
media header is updated, except when SLRtape50, SLR32,
SLRtape24, SLR5 or DC9250 type medium is used. Note that
the media header is only updated after write type
operations. When only read type operations are performed
the media header will not be updated and the new counter
value will not be saved.
incremented during the media header update operation and
this increment will not be saved on the medium.
(Note: This bit can not be changed by the initiator)
An Enable Threshold Comparison (ETC) bit indicates
whether comparison to the threshold value is performed
or not.
The default value is 0. See the LOG SELECT command for
further description.
The Threshold Met Criteria (TMC) field is valid only if
ETC bit is 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.
The Cartridge BOT Pass Counter is incremented each time
the Load Point (LP) tape marker is passed in forward
direction. The counter is normally incremented by one
for each track turn operation at BOT, incremented by one
or two for each physically load operation and
incremented by two for each media header update.
Any attempt by initiator to alter this counter value
will be ignored
