Byte 0, Bit 7 – DU (Disable Update)

The value returned for the Disable Update field indicates whether

updates to the current cumulative value for this counter are enabled

or disabled, as follows:

0 – The CTS can update the current cumulative value, so comparisons

between the current cumulative value and the threshold value

occur normally.

1 – The CTS will not update the current cumulative value, so

threshold conditions will not be met for this counter.

Byte 02, Bit 6 – DS (Disable Save)

The CTS always returns 1 for this bit, indicating that it does not

support the saving of log parameters.

Byte 02, Bit 5 – TSD (Target Save Disable)

The CTS always returns 1 for this bit, indicating that it does not

support the saving of log parameters.

Byte 02, Bit 4 – ETC (Enable Threshold Comparison)

The value returned for the ETC bit indicates whether threshold

comparisons are enabled or disabled for this counter, as follows:

0 – Threshold comparisons are disabled for this counter.

1 – Threshold comparisons are performed on this counter.

When threshold comparisons are enabled (and the DU bit is 0), the

CTS compares the current cumulative value to the threshold value for

the counter. When the conditions specified by the TMC bit are met,

the CTS returns Check Condition status with the sense key set to Unit

Attention (6h), the ASC and ASCQ set to 5Bh and 01h, and the Fault

Symptom Code set to CAh.

Threshold comparisons are made when the cumulative value is

updated. When the threshold criteria are met, the CTS returns Unit

Attention.
