Table
Field | Default | Description | |
Value | |||
|
| ||
PS | 1 | Parameters Savable. This bit is only used with the MODE SENSE command. A returned | |
value of 1 indicates that the target is capable of saving the page in a | |||
|
| ||
|
| Performance. This bit enables/disables | |
|
| V, this means enabling or disabling flushing of SMART data to the media (done hourly). | |
|
| The prediction algorithm is designed to reset the current accumulated data approximate- | |
PERF | 1 | ly every 100,000 blocks read or written per head. | |
| |||
|
| When this bit = 0, current accumulated SMART data is preserved across power cycles. | |
|
| When this bit = 1, current accumulated SMART data is lost across power cycles. | |
|
|
| |
EWASC | 1 | Enable Warning ASC. When this bit = 0, reporting of thermal warming is disabled. | |
When this bit = 1, thermal warning reports are enabled. | |||
|
| ||
|
|
| |
|
| Disable Exceptions. This bit is used to enable or disable SMART exception reporting. | |
DExcpt | 0 | When this bit = 0, SMART exception reporting is enabled. | |
When this bit = 1, all SMART functions are disabled, including reporting SMART ex- | |||
|
| ||
|
| ceptions, running the prediction algorithm, and accumulating SMART data. | |
|
|
| |
|
| When this bit = 0, the test function is disabled. | |
Test | 0 | When this bit = 1, the disk drive reports false SMART trip reports as prescribed in the | |
MRIE field (see below). Interval timer field and report count and method fields apply. | |||
|
| ||
|
| When the test bit forces a SMART failure, the failure is reported with a sense code/qual- | |
|
| ifier of 5D/FF. | |
LogErr | 0 | When this bit = 0, it indicates that log sense information is | |
NOTE: LogErr = 0 is the only value supported. | |||
|
| ||
|
| Method of Reporting Informational Exceptions. The value within this field indicates the | |
MRIE | 4 | method that will be used by the disk drive to report informational exception conditions, | |
as shown in Table | |||
|
| ||
|
| ceptions is | |
|
|
| |
|
| This field indicates the period, in 100 millisecond increments, for reporting that an in- | |
|
| formational exception condition has occurred. The disk drive will not report such con- | |
|
| ditions more frequently than the time specified by the Interval Timer field and as soon | |
|
| as possible after the timer interval has elapsed. After the condition has been reported, | |
|
| the interval timer restarts. | |
Interval | 0 | A value of 0 in the Interval Timer field indicates that the disk drive will only report the | |
Timer | informational exception condition once. A value of FFFFFFFFh in the Interval Timer | ||
| |||
|
| field indicates that the timer interval is | |
|
| If the disk drive’s predictor detects a SMART threshold trip, it reports the failure only | |
|
| if it has not reported a failure within the last interval timer period. A value of 0 means | |
|
| that there is no required waiting between SMART reports. | |
|
| NOTE: The Interval Timer field does not apply to MRIE mode 6. | |
|
|
| |
|
| The value contained in this field indicates the number of times to report an informational | |
|
| exception condition to the application client. A value of 0 in this field indicates there is | |
|
| no limit on the number of times the disk drive will report an informational exception | |
|
| condition. | |
|
| Each time the disk drive detects a SMART failure, the SMART status is reported the | |
Report Count | 1 | number of times indicated by the value of the Report Count field. | |
| |||
|
| The disk drive then resets its cumulative values and continues with its predicting activ- | |
|
| ity. The SMART threshold trip remains permanent (or until a LOG SELECT command | |
|
| clears it) and can be retrieved at any time using MRIE mode 6. | |
|
| NOTE: The Report Count field does not apply to MRIE mode 6. | |
