Note that if an attempt is made to set or clear a flag that is not supported by the drive,
CHECK
CONDITION
will be reported with a sense key of

and additional sense of 2600h
(invalid field in parameter list).
Device Time mode page
The Device Time Mode page consists of the following page header followed by three Timebase
descriptors:
MRIE
Method of Reporting Informational Exceptions
3h This field indicates the method used by the target to report informational
exception conditions and must be set to 3. The target will report informational
exception conditions by returning a CHECK CONDITION status on any
command. The sense key will be set to RECOVERED ERROR with additional
sense of 5D00h (failure prediction threshold exceeded). The command that has
the CHECK CONDITION will complete without error before any informational
exception condition may be reported.
Interval Timer
0 Must be zero, indicating that the drive only reports an informational exception
condition once.
Report Count/Test
Flag Number
0 If the Test bit is zero, this field is the Report Count and must be zero, indicating
that there is no limit on the number of times the drive can report an informational
exception condition.
n If the Test bit is one, this field is the Test Flag Number, that is, the number of a
supported TapeAlert flag. The target will generate a test informational exception
condition. As a result, the next SCSI command after Mode Select will return
CHECK CONDITION with a sense key of RECOVERED ERROR and additional
sense of 5DFFh (failure prediction threshold exceeded - false).
The following are valid settings:
1 through 64
This sets the TapeAlert flag with this number in the
Log page.
−
1 through
−

target in the Log page.
