Setmark Counter Log Parameters
The Parameter Code is set to 0001h.
A Disable Update (DU) bit set to 0 indicates that the
Drive is free to update the counter.
A DU bit set to 1 indicates that the Drive shall not
update the counter except in response to a LOG SELECT
command that specifies a new value for the counter.
The initiator may use the LOG SELECT command to set or
clear the DU bit.
The Drive will set the DU bit to 1 when the counter
reaches its maximum value (FFFFFFFFh).
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)
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.
This counter counts the number of setmarks received from
or reported to the Initiator, and the number of setmarks
being spaced over on the Initiators request (using SPACE
Over Setmarks command)
1
The counter always counts up without regard to the direction of the
space command.
