PS
The Parameter Savable (PS) bit must be set to zero (this
page is not saveable).
Page Code
The Page Code for this page must be set to 1Ch.
Parameter Length
The Page Length field must always be set to 0Ah.
PERF
The Performance (PERF) bit has to be set to 0 to
indicate that informational exception operations that
may cause delays are acceptable.
DExcpt
The Disable Exceptions (DExcpt) bit has to be set to 1
to indicate the drive shall disable all information
exception operations and ignore the MRIE field. The host
must poll the TapeAlert information Log Page to see if
an Informational Exception Condition has occurred.
TEST
When the TEST bit is set to 1, the test action is based
on the value in the Test Flag Number field.
When the TEST bit is set to 0, the drive will not
generate any test/false informational exception
conditions.
A MODE SENSE command always returns a value of 0 for the
TEST bit.
LOGErr
The LOG Error (LOGErr) bit has to be set to 0.
MRIE
This field has to be set to 0 (not used since DExcpt
always is set to 1).
Interval Timer
The Interval Timer field has to be set to 0 to indicate
that the drive only reports the informational exception
condition one time.
