Log Select Command
The initiator uses the Log Select command to manage information about the
device or media.
Notes:
• Setting the parameter code reset bit to one, clears all cumulative
statistics.
• If the parameter code reset (PCR) bit is set to 0, this command is
ignored and no values are reset.
• If the SP bit and the parameter list length field are not both 0, this
command is rejected.
