TMC (Threshold Met Criteria)
This field defines the basis for comparison of the cumulative and threshold values. See Table 125 for meanings of values in
this field. The TMC field is only valid when the ETC bit is one.
* Comparison made at every update of cumulative value.
If the ETC bit is one* and the result of the comparison is true, a unit attention condition is generated for all initiators. When
reporting the unit attention condition the drive sets the sense key to Unit Attention, and the additional sense code to Thresh-
old Condition Met.
* The RLEC bit (Report Log Exception Condition) in Mode page 0AH (Table 153) must also be one.
TSD (Target Save Disable)
0 The drive saves frequently enough to insure statistical significance. The drive’s method is to save after each thermal
calibration, which is once every ten minutes.
1 The drive does not use its save method.
The page code assignments for the log pages are listed in Table 126. Detailed descriptions follow the table.Table 125: Threshold Met Criteria
Code Basis for Comparison
00b Notify of every update of cumulative value
01b* Cumulative value equal to threshold value
10b* Cumulative value not equal threshold value
11b* Cumulative value greater than threshold value
