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.
