9.1 About This Command

The LOG SENSE command enables you to retrieve statistical

information about the CTS’s read and write error recovery operations.

The CTS maintains this information in the following counters, which

are described in Table 9-1 and Table 9-2:

Total Number of Rewrites

Total Number of Rereads

Total Errors Corrected

Total Times Errors Processed

Total Bytes Processed

Total Unrecoverable Errors

Note: You can use the LOG SELECT (4Ch) command to specify

cumulative and threshold values for these counters. Refer to

Chapter 8 for more information.

As described in this chapter, the LOG SENSE data returned by the

CTS consists of a four-byte Parameter List Header and a log page.

Each log page contains zero or more log parameter data blocks, which

provide information about the counters.

9.2 Field Definitions

Byte 01, Bits 4 through 2 – Reserved

These bits are reserved.

Byte 01, Bit 1 – PPC (Parameter Pointer Control)

The PPC bit specifies what type of parameters you are requesting

from the CTS. This bit must be 0, which indicates that the CTS should

return all parameters for the selected log page, beginning with the

code in the Parameter Pointer field (bytes 05 and 06).

Byte 01, Bit 0 – SP (Save Parameters)

The CTS does not support the save parameters function. The valid

value for this bit is 0.
