Notes.
[a] The Page Length field specifies the length in bytes of the following supported page list.
[b] The Supported Page List field shall contain a list of all log page codes implemented by the target in
ascending order beginning with Page Code 00h.
[5]
The Parameter Pointer field contains a Parameter Code that specifies that log parameter data be returned
to the initiator by the Data In phase starting with the Parameter Pointer code log parameter data and con-
tinuing to the maximum allocation length or to (and including) log parameter data of the maximum param-
eter code supported by the drive, whichever is less. If the value of the Parameter Pointer field is larger
than the largest available parameter code that can be returned by the drive on the specified page, the
drive terminates the command with a Check Condition status. The sense key is set to Illegal Request and
the additional sense code is set to Invalid Field In CDB.
[6]
The Allocation Length field informs the drive of the amount of space available for returning log parameter
data. The initiator can retrieve the rest of the log page information by setting the parameter pointer to the
last returned parameter code and reissuing the Log Sense command. This process may be repeated as
necessary to retrieve all the available information.
