Control Mode Page — Field Descriptions
Field Name
Description
RLEC
Report Log Exception Condition. The RLEC bit works with the Read / Write Error
Log Page. A Report Log Exception Condition (RLEC) bit of 1 specifies that the
target reports log exception conditions. An RLEC bit of 0 specifies the target does
not report log exception conditions. Refer to the TMC bit description in
Table 4-16
on page 4-28
.
The RLEC bit indicates whether the tape drive should return CHECK
CONDITION status with the Sense Key set to UNIT ATTENTION (06h) when
one of the write and read error counters of the log pages reach a specified threshold
as follows:
0 – Do not return Unit Attention when a threshold condition is met.
1 – Return Unit Attention when a threshold condition is met.
Note:
See
“LOG SELECT Page Format” on page 4-19
for information on how to
change the threshold.
