4.8.3 Read/Write Error LOG SENSE Page (Pages 02h and 03h)
Each log page begins with a 4-byte header followed by
n
number of log parameter blocks, with each
block containing 8 bytes, except for parameter code 05h. The log parameter block for the parameter
total bytes processed (05h) is 12 bytes, since the parameter value is 8 bytes long.

Description
Page Code
The Page Code echoes the page code that was specified in the LOG SENSE CDB.
Page Length
The Page Length specifies the total number of bytes contained in this log page, not
including the four bytes of the header.
For example, if the PPC bit is 0 and Parameter Pointer is 0, the target returns
4 bytes of page header, with page length of 3Ch, followed by 8 bytes of log
parameter data for each parameter code, except for parameter code 05h. For code
05h, it returns 12 bytes.
Parameter codes may be 8 or 12 bytes long. Refer to the following table for the
length of each Parameter Code.
