Something from the old notes. It’s simple and straight forward, and iLO sucks in my opinion - syntax-wise. Anyways, to reboot it, you have to be able to SSH into it:

[somedude@jh-1 /home/somedude]$ ssh Administrator@10.100.100.188
Administrator@10.100.100.188's password:
User:Administrator logged-in to hyper-1.unixpowered.com(10.100.100.188 / FE80::AF1:EAFF:FEEA:DED8)
iLO Advanced 2.14 at  Feb 11 2020
Server Name: hyper-1.unixpowered.com
Server Power: On

And now, reboot it…

</map1>hpiLO-> reset /map1
