PC Page Control. This field defines the type of
parameter values to be selected:
PC Type of Parameter Values
00b - Current Threshold Values
01b - Current Cumulative Values
10b - Default Threshold Values
11b - Default Cumulative Values
All of these types of values are changeable using
LOG SELECT.
When the PC field is set to 00b or 01b and the
Parameter List Length is set to 0, the command
terminates with a CHECK CONDITION status,
Sense Key of ILLEGAL REQUEST, and ASC of
INVALID FIELD IN CDB. This occurs because
modification of Current Threshold Values and
Current Cumulative Values is not supported.
When the PC field is set to 10b and the Parameter
List Length field is set to 10b, then all Current
Threshold Values are reset to the Default
Threshold Values. This is equivalent to no
change, since Threshold Values cannot be
modified.
When the PC field is set to 11b and the Parameter
List Length field is set to 0, then all Current
Cumulative Values are reset to the Default
Cumulative Values. This is equivalent to clearing
all log pages that can be cleared.
