Figure 8-12 LOG SELECT CDB
LOG SELECT allows the host to manage statistical information maintained by the
device about its own hardware or the installed media. The description should be read in
conjunction with the description of the LOG SENSE command which follows it, to
provide the reader with information about log page format, parameters, and supported
pages. The command specific bits are used as follows:
•
PCR - If Parameter Code Reset bit is set to 1 and parameter list length is 0, all
accumulated values of page code 2, 3, and 32 are set to zero and all threshold
values are set to default. If PCR is set to 1 and the Parameter List Length Field is
not zero, the command will be terminated with a CHECK CONDITION Status,
with Sense Key of ILLEGAL REQUEST, and ASC of INVALID FIELD IN CDB.
•
SP - The Save Page bit is not supported and must be set to zero. If the SP bit is set,
the command will be terminated with CHECK CONDITION Status, with Sense
Key of ILLEGAL REQUEST, and ASC of INVALID FIELD IN CDB.
•
PC - The Page Control field defines the type of parameter values to be selected:
