These columns identify the I/O statistics reported from the extent driver.
Column Name | Mode | Description | Data Type |
---|---|---|---|
ReadsCold | count | Total number of reads issued to all cylinders that are considered COLD. A cylinder is considered to be COLD if the response time of its associated physical storage is less than TVS Percentile Cold Lower Bound configuration setting. This column is not currently valid. It should not be used.

FLOAT |
ReadsHot | count | Total number of reads issued to all cylinders that are considered HOT. A cylinder is considered HOT if the response time of its associated physical storage is greater than the Teradata VS Percentile Hot Lower Bound configuration setting. This column is not currently valid. It should not be used.
|
FLOAT |
ReadsWarm | count | Total number of reads issued to all cylinders that are considered WARM. A cylinder is considered to be WARM if the response time of its associated physical storage is between TVS Percentile Hot Lower Bound and TVS Percentile Cold Upper Bound configuration settings. This column is not currently valid. It should not be used.
