<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
(

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.

0
is returned if the status is normal and
1
is returned if an error is detected. Table 5‒42: List of
