LOG SELECT Command (4Ch) (continued)

Table 5–18 LOG SELECT Log Parameters Field Descriptions (continued)

Field Name

Description

 

 

Parameter Code

Note: Parameter codes 00h, 01h, and 04h always have a value of 0.

(continued)

Parameter value for 05h is 8 bytes; the parameter length is set to 8.

DU

Disable Update. This bit is not defined for LOG SELECT; the target ignores any

 

value in DU.

DS

Disable Save. Not supported. Must be set to 1.

TSD

Target Save Disable. Not supported. Must be set to 1.

ETC

Enable Threshold Comparison. When set to 1, drive performs a comparison

 

with threshold values once the cumulative value is updated. Comparison

 

criteria are defined in Threshold Met Criteria (TMC). If the comparison is met

 

and the RLEC bit of MODE SELECT / SENSE Control Page 0Ah is set to 1, then a

 

UNIT ATTENTION is generated for all initiators. The additional sense code is set

 

to THRESHOLD CONDITION MET. If the RLEC bit is 0 and the comparison is

 

met, then UNIT ATTENTION is not generated.

TMC

Threshold Met Criteria. Once the criteria specified in this field is met and the

 

ETC bit is 1 and the RLEC bit in MODE SENSE / SELECT Control Page is set to 1,

 

then UNIT ATTENTION is generated for all initiators.

 

The criteria for comparison are:

 

Code - Basis of Comparison

 

00b - Every update of the cumulative value

 

01b - Cumulative value equal to threshold value

 

10b - Cumulative value not equal to threshold value

 

11b - Cumulative value greater than threshold value

 

The Default Threshold Values are the maximum values that each parameter

 

can attain.
