Cartridge Load Counter Parameters
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
(FFFFFFh) 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 0 to indicate that
the Drive does 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 0. The Drive
will save this log parameter each time a cartridge is
unloaded.
(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 03h to indicate that the counter is
3 bytes wide.
The Cartridge Load Counter increments each time a new
cartridge is physically loaded in the Drive.
Any attempt by initiator to alter this counters value
will be ignored
