8.5 Exceptions and Error Conditions

The following exceptions and error conditions can occur with the

LOG SELECT command.

Illegal Value in LOG SELECT Data

If one of the bytes sent with the LOG SELECT data contains an illegal

value or if a reserved bit is set, the CTS returns Check Condition

status. To determine which byte contains the error, issue a REQUEST

SENSE command. The sense key will be set to Illegal Request (5h) and

the Fault Symptom Code field (byte 28) will indicate which of the

consecutively received bytes is in error. For example, if the Page Code

field (byte 00, bits 5 through 0) in the Parameter List Header is

invalid, the value for the Fault Symptom Code byte would be 01h.

Note: The CTS counts the first byte received as byte 1, not as byte 0.

Other Errors

The CTS may return the Fault Symptom Codes (FSCs) listed in

Table 8-4 when thresholds are implemented.

Important

If you want the CTS to return these Fault Symptom Codes to

notify you about changes to the counters, first issue a MODE

SELECT (15h) command and send the Control Mode page

(Page Code=0Ah) with the RLEC bit set to 1. Refer to

Chapter 10 for more information.

In addition, be sure to set the DU bit to 0 and the ETC bit to 1

for the log parameter.
