FENCE_AGENT(8)
β¨ fence_ilo_ssh β the manual, but make it make sense π
okay so bestie, you're looking at FENCE_AGENT(8) from the System Manager's Manual β and specifically the HP iLO-over-SSH fencing squad. Let's get into it, no cap. π«Ά
πΈ NAME πΈ
fence_ilo_sshβ the actual fence agent for HP iLO, but over SSHfence_ilo3_sshβ fence agent for HP iLO3 over SSH (it's a symlink, bestie, it's giving alias energy)fence_ilo4_sshβ fence agent for HP iLO4 over SSH (also a symlink)fence_ilo5_sshβ fence agent for HP iLO5 over SSH (you guessed it, symlink π )
π¦ DESCRIPTION π¦
So fence_ilo4_ssh is a Power Fencing agent that connects to an iLO device. It logs into the device via ssh and reboots a specified outlet. That's the whole vibe. π₯
β οΈ WARNING: themonitoraction is prone to timeouts. Use thefence_iloequivalent to avoid this issue. Not me warning you twice β this is literally the original warning, so take it seriously, fr fr.
The fence agent accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. But the agent can also be run by itself with command line options β which is lowkey iconic for testing, and for turning outlets on or off from scripts. β¨

okay that's the whole thing, bestie, you ate that ππ this was fence_ilo_ssh (Fence Agent), dated 2009-10-20, and yeah the footer is literally the same as the header: FENCE_AGENT(8). iconic of it, honestly. go fence something responsibly π
