  3. note:

    ICN error log remains even though ICN is replaced.

    ICN Monitor Display shows ICN sensor logs stored in '/usr/g/service/log/sensor_logs' directory.

    ('ICN Monitor Display' is shown from 'MR Service Desktop/Diagnostics/VRE Subsystems/ICN Monitor Display'.)

    This log is not automatically removed after ICN is replaced.

    As a result, you will see error log of previouse ICN even though it is replaced to the new ICN.

    By performing the following procedure, the old log will be removed.

    Remove log stored in '/usr/g/service/log/sensor_logs' directory as follows.
    1. Open C Shell Window.
    2. Enter 'cd /usr/g/service/log'.

      % cd /usr/g/service/log

    3. Enter '\cp -R sensor_logs sensor_logs.old' to make backup of old log file.

      % \cp -R sensor_logs sensor_logs.old

    4. 4 . Enter as follows.

      % su

      （enter password）

    5. Enter 'cd /usr/g/service/log/sensor_logs'.

      % cd /usr/g/service/log/sensor_logs

    6. Enter 'ls -l' and hit [Enter] to check the log files. (following is just example.)
