[8] Parameter Length. This field specifies the length in bytes of the parameter that follows. If the initiator
sends a parameter length value that results in the truncation of the parameter value, the drive terminates
the command with a Check Condition status. The sense key shall be set to Illegal Request with the
additional sense code set to Invalid Field In Parameter List.
[9] Parameter Value. This field uses one, two, four or eight bytes to transmit an unsigned counter value. The
initiator sends counts to set values into counters in the drive, and the drive returns counter values to the
initiator. The initiator is responsible to issue a Log Sense command to learn the parameter length the
target has selected.
When any counter in a log page reaches its maximum value, the drive ceases incrementing all counters
in that log page. If the RLEC bit of the Control Mode page is one, then the drive reports the exception
condition as described in note [2] above.
The page code assignments for the log pages are listed in Table 5.1.3.2-6. Detailed descriptions follow the
table.
