LOGERR (Log Errors) is not used and ignored internally by the Target.
Ÿ
EWASC (Enable Warning ASC) bit of zero indicates that Temperature Warning will not be reported.
An EWASC bit of one allows Temperature Warning to be reported when DEXCPT bit is set to zero. If
the temperature reading inside of DE exceeds the threshold (default or set by Mode Select Page 0),
Recovered Error (Sense Key 01h, ASC 0Bh, ASCQ 01h) will be reported.
DEXCPT bit of zero indicates that informational exception operations shall be enabled. The reporting
of informational exception conditions when the DEXCPT bit is set to zero is determined from the
method of reporting informational exceptions field.
Note: Disable exception control (DEXCPT) bit of zero indicates the failure prediction threshold
exceeded reporting shall be enabled. The method for reporting the failure prediction threshold ex-
ceeded when the DEXCPT bit is set to zero is determined from the method of reporting informational
exceptions field. A DEXCPT bit of one indicates the target shall disable reporting of the failure pre-
diction threshold exceeded. The method of reporting informational exceptions field is ignored when
DEXCPT is set to one and EWASC is set to zero.
Ÿ
DEXCPT (Disable Exception Control) bit of zero indicates information exception operations are
enabled. The reporting of information exception conditions when the DEXCPT bit is set to zero is
determined from the Method of Reporting field. A DEXCPT bit of one indicates the Target disabled
all information exception operations.
Ÿ
TEST bit of one instructs the drive to generate false drive notifications at the next interval time, (as
determined by the INTERVAL TIMER field), if the DEXCPT is zero. The Method of Reporting and
Report Count would apply. The false drive failure is reported as sense qualifier 5DFFh. The TEST bit
of zero instructs the drive to stop generating any false drive notifications.
