status. The sense key is set to ILLEGAL REQUEST and the additional sense code is set
to INVALID FIELD IN CDB.
If the target does not support a parameter code within this page then it will not return
any data associated with this parameter.
SP
Saving log parameters is not supported and shall be always zero.
If the SP bit is set, the command is terminated with CHECK CONDITION status with
the sense key set to ILLEGAL REQUEST, and an additional sense code of INVALID
FIELD IN CDB.

The Page Control field defines the type of parameter values to be returned:
PC
Type of Parameter Values
Threshold Values
Cumulative Values
Default Threshold Values
Default Cumulative Values
00b
01b
10b
11b
Figure 8-18 LOG Page Control Definitions
The Default Threshold Values are the maximum values that each parameter can attain.
The Current Cumulative Values are the values computed since the last reset of the
device (either by power-cycling, BUS DEVICE RESET, or SCSI RESET).
The Default Cumulative Values are the values to which each parameter gets initialized
on a reset condition as described previously. Default values are zero.
By default Current threshold values = Default threshold values.
