Nintrix, Both would do the same thing of restarting the iDrac, now if your goal is to in fact reset the iDrac to defaults that would be the racadm racresetcfg command.
Hi all, I am just wondering if the racadm racreset hard command do the same thing as if I will do it via gui Overview – Server under Quick Launch Tasks; is ‘Reset idrac'. Thank you
