Table 5-46
Field
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 Summary page reports the number of
Parameter Code
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.
Target Save Disable. This parameter is 0 indicating that the drive provides a target-spe-
TSD
cific way of saving parameters.
Enable Threshold Comparison. This parameter is always 0. The drive does not use
ETC
thresholds for any of its parameters.
Threshold Met Comparison. This parameter is always 0. The drive does not use thresh-
TMC
olds for any of its parameters.
List in Binary. This bit only valid if LP = 1. If LP = 1 and LBIN = 0, then the List Pa-
LBIN rameter 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.
List Parameter. When 0, indicates that the parameter value for this parameter is a nu-
meric value. When LP is a 1, it indicates that the parameter value is an alphanumeric
LP
ASCII-string list.
This parameter is always 0.
Parameter Length Specifies the length, in bytes, of the parameter's value.
Contains the parameter's current value when the PC field of the LOG SENSE command
Parameter Value
is 01b.
Note:
The DU, DS, TSD, ETC, TMC, LBIN and LP fields are collec-
tively referred to as the Parameter Control Byte. This byte gen-
erally 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.
