Quantum DLT 8000 Tape System
LOG SENSE Command (4Dh) (continued)
5.8.3 READ (Page 03h) / WRITE (Page 02h) ERROR LOG SENSE Page
Each Log page begins with a 4-byte header followed by a number of log parameter blocks.
Each block consists of 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 command descriptor block.
Page Length
The Page Length field specifies the total number of bytes contained in
this log page, not including the four bytes that make up the header.
For example, if the PPC bit is 0 and the parameter pointer is 0, the target
returns 4 bytes of page header with page length of 44h followed by 8
bytes of parameter value data for each parameter code except code 05h
(for code 05h, it returns 12 bytes). Therefore, for parameter codes 00h,
01h, 02h, 03h, 04h, 06h, and 8000h, each page will be 8 bytes.
