5.18.16 swdt_start
<Name>
swdt_start - Restart the software WDT.
<Format>

swdt_start

<Description>
Running this command with root privileges restarts software WDT (fixed priority process in-loop monitoring) that
is temporarily stopped. However, because the definition of fixed priority process in-loop monitoring has a higher
priority, if the command is issued when monitoring has stopped by /hitachi/etc/swdt.conf (OFF is
defined for the INLOOP symbol), the command terminates abnormally without restarting monitoring. If the
command is issued when monitoring has already started, the command terminates normally without doing
anything.
<Diagnosis>
For the exit code, 0 is returned if the status is normal and 1 is returned if an error is detected. Table 5‒42: List of
swdt_start command error messages below shows error messages that are output when an error is detected.
