Non-Volatile Log Page
(38h)
4
Log page 38h provides access to a 64 byte non-volatile buffer in the tape
drive for general purpose use. The log page contains one 64 byte
parameter with a Parameter Code setting of 0. The 64 bytes in the
Parameter Value field contain the data from the Parameter Value field the
last time a
LOG SELECT
command was processed that contained page
38h.
Time Stamp
Power-on hours when
CHECK CONDITION
status occurred. This is the number of
power-on hours since the last time the drive was powered on, not total number of
hours during the lifetime of the drive.
The time stamp counter is updated once per hour. If the drive is powered down
before the hourly update occurs, the update does not occur until a full hour after
power is re-applied.
Media ID
Internal media identifier being used when
CHECK CONDITION
status occurred. A
value of 0 indicates no media or unknown media when the event occurred. Note
that this is not a legitimate method of tracing media.
