Marcos, You will need OMSA or another software agent in order to use the watchdog. OMSA provides a GUI and CLI method to enable the watchdog. Once the watchdog is enabled, OMSA sends heartbeats to the iDrac to keep the watchdog from expiring. If you were to get the watchdog enabled without OMSA, the timer would expire and your system would reboot.
In theory, you could use ipmitool to enable the watchdog and then execute ipmitool with the heartbeat cmd at a regularly scheduled time. I don't believe ipmitool has user friendly commands to do this, so you would have to enter raw ipmi commands. You would need to make sure the heartbeat executes at a duration that is shorter than what you have the watchdog timer set to.
