The "Parameter Pointer" field allows the application client to request parameter data beginning from s specific parameter code to the maximum allocation length or the maximum parameter code supported by the target, whichever is less. If the value of the "Parameter Pointer" field is larger than the largest available parameter code known to the device server for the specified page, the HDD terminates the command with CHECK CONDITION status (ILLEGAL REQUEST [=5] / Invalid field in CDB [=24-00]).

The "Parameter List Length" field in the CDB specifies the total number of bytes of log parameter which can be transferred to the INIT by this command. The HDD transfers the number of bytes of all log parameters specified in the "Page Code" field or the portion of log parameters with the length specified in the "Parameter List Length" field, whichever is smaller. When zero is specified in the "Parameter List Length" field, this command is terminated without anything being transferred.

Log parameters

This clause describes the log page structure and the log pages that are applicable to all devices. Pages specific to each device type are described in the command standard that applies to that device type. The LOG SENSE command returns a single log page specified in the page code field of the command descriptor block. For information on this parameter, see Chapter 5, "Parameter Data Format."
