mw1379 was reimaged and everything went normal, just at the very end after the final reboot triggered by the reimaging script it never came back and stayed down.
I connected to mgmt in an attempt to powercycle it and found this unusual DRAC behaviour:
racadm serveraction powerstatus - ON
racadm serveraction powerup - already up
racadm serveraction powerdown - can't execute command
racadm serveraction powercycle - can't execute command
Then i did a "racadm racreset" and was able to send those commands again.
