Table 5-46Generic Log Parameter-Field Descriptions

 

 

 

Field

 

Description

 

 

 

 

 

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

Parameter Code

 

while the same code on the Block Replacement Summary 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-spe-

 

cific 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 thresh-

 

olds 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 Pa-

 

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-

LP

 

meric value. When LP is a 1, it indicates that the parameter value is an alphanumeric

 

ASCII-string list.

 

 

 

 

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.

 

 

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.
