Table 5-50 Generic Log Parameter-Field Descriptions
Note: The DU, DS, TSD, ETC, TMC and LP fields are collectively re-
ferred to as the Parameter Control Byte. This byte generally has
a value of 0; however, if the page is non-volatile but the drive is
not spun up or the GLTSD bit is set in Mode Page 0Ah, then the
value would be 20h. If the page is volatile, then the value is 60h.

Parameter Code
A code which uniquely identifies each parameter on a given Log Page. For
example, the code 8002h on the Seek Performance Summary page reports
the average seek time while the same code on the Block Replacement Sum-
mary page reports the number of blocks replaced.
The following pages in this manual contain the lists of applicable parameters
for each Log page.
DU Disable Update. This parameter is 1 when updates are not enabled.
DS
Disable Save. This parameter is 1 when parameters are not saved by the
drive.
TSD
Target Save Disable. This parameter is 0 indicating that the drive provides
a target-specific way of saving parameters.
ETC
Enable Threshold Comparison. This parameter is always 0. The drive does
not use thresholds for any of its parameters.
TMC
Threshold Met Comparison. This parameter is always 0. The drive does not
use thresholds for any of its parameters.
LBIN
List in Binary. This bit only valid if LP = 1. If LP = 1 and LBIN = 0, then
the List Parameter is a string of ASCII graphic codes (code values 20h
through 7Eh). If LP = 1 and LBIN = 1, then the parameter is a list of binary
information.
LP
List Parameter. When 0, indicates that the parameter value for this param-
eter is a numeric
XCNWG When LP is a 1, it indicates that the parameter value
is an alphanumeric ASCII-string NKUV
This parameter is always 0.
Parameter Length Specifies the length, in bytes, of the parameter’s value.
Parameter Value
Contains the parameter’s current value when the PC field of the LOG SENSE
command is 01b.
