9.5 Log Parameter Data Blocks

(Page Codes=02h and 03h)

When the Page Code is 02h or 03h, the CTS returns information about

its log parameters (counters) immediately after it returns the

Parameter List Header. For each counter, the CTS returns a data block

that includes four bytes of descriptive information and a

variable-length parameter value. The total number of bytes returned

for each counter is equal to the value for the Parameter Length field

plus four.

The CTS returns the log parameter data blocks for the specified LOG

SENSE page in Parameter Code order (unsigned). The code for the

first counter will be equal to or greater than the value you specified

for the Parameter Pointer field in the CDB.

Bytes 00 and 01 – Parameter Code

The Parameter Code field identifies the code of the counter for which

the CTS is returning a value, as follows:

0002h – Total Rewrites or Total Rereads, depending on the Page Code

0003h – Total Errors Corrected

0004h – Total Times Errors Processed

0005h – Total Bytes Processed

0006h – Total Unrecoverable Errors

These counters are described in Table 9-1 and Table 9-2.
