• Current attribute value
The current attribute value is the normalized raw attribute data. The value
varies between 01h and 64h. The closer the value gets to 01h, the higher the
possibility of a failure. The device compares the attribute values with
thresholds. When the attribute values are larger than the thresholds, the
device is operating normally.
• Attribute value for the worst case so far
This is the worst attribute value among the attribute values collected to date.
This value indicates the state nearest to a failure so far.
• Raw attribute value
Raw attributes data is retained.
