4-40 January 2005 81-81200-02 REV A01
Table 4-22. LOG SENSE Command Descriptor Block — Field Descriptions
Field Name Description
PPC Parameter Pointer Control. When set to 0, indicates that the parameter data
requested from the drive starts with the parameter code specified in the
Parameter Pointer field (bytes 5 – 6) and returns the number of bytes specified
in the Allocation Length field (bytes 7 – 8) in ascending order of parameter
codes from the specified log page. When set to 1, the drive returns only the
parameters that have changed since the last time the page was read.
SP Save Parameters. Not supported. Must be set to 0. If the Save Parameters bit is
set to 1, the drive terminates the command with CHECK CONDITION status,
Sense Key set to ILLEGAL REQUEST, and Additional Sense Code set to
INVALID FIELD IN CDB.
PC Page Control. This field defines the type of parameter values to be returned:
Code Type of Parameter Values
00b Threshold Values
01b Cumulative Values
10b Default Threshold Values
11b Default Cumulative Values
• 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 drive by power-cycle, TARGET RESET, or SCSI RESET.
• The Default Cumulative values are the values to which each parameter is
initialized at a reset condition. Default values are 0.
• By default, Current Threshold Values are set to Default Threshold Values.
Page Code The Page Code field identifies the log page the initiator requested. If the drive
does not support the specified page, the drive terminates the command with
CHECK CONDITION status, Sense Key set to ILLEGAL REQUEST, and
Additional Sense Code set to INVALID FIELD IN CDB. The drive supports the
following pages:
