✨ fence_ilo_ssh β€” the manual, but make it make sense πŸ’–

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. 🫢


🌸 NAME 🌸

  • fence_ilo_ssh β€” the actual fence agent for HP iLO, but over SSH
  • fence_ilo3_ssh β€” fence agent for HP iLO3 over SSH (it's a symlink, bestie, it's giving alias energy)
  • fence_ilo4_ssh β€” fence agent for HP iLO4 over SSH (also a symlink)
  • fence_ilo5_ssh β€” fence agent for HP iLO5 over SSH (you guessed it, symlink πŸ’…)

πŸ¦‹ DESCRIPTION πŸ¦‹

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. πŸ”₯

⚠️ WARNING: the monitor action is prone to timeouts. Use the fence_ilo equivalent 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. ✨

πŸ’… PARAMETERS πŸ’…

  • -o, --action=[action] β€” the fencing action (Default Value: reboot)
  • -c, --command-prompt=[prompt] β€” force Python regex for command prompt (Default Value: ['MP>', 'hpiLO->'])
  • -k, --identity-file=[filename] β€” identity file (private key) for SSH
  • -4, --inet4-only β€” forces the agent to use IPv4 addresses only
  • -6, --inet6-only β€” forces the agent to use IPv6 addresses only
  • -a, --ip=[ip] β€” IP address or hostname of fencing device
  • -u, --ipport=[port] β€” TCP/UDP port to use for connection with device (Default Value: 23)
  • -m, --method=[method] β€” method to fence (onoff|cycle) (Default Value: onoff)
  • -p, --password=[password] β€” login password or passphrase
  • -S, --password-script=[script] β€” script to run to retrieve password
  • -n, --plug=[ip] β€” IP address or hostname of fencing device (together with --port-as-ip)
  • -x, --ssh β€” use SSH connection
  • --ssh-options=[options] β€” SSH options to use
  • -l, --username=[name] β€” login name. This parameter is always required. (yes, always, don't skip it πŸ™ˆ)
  • -q, --quiet β€” disable logging to stderr. Does not affect --verbose or --debug-file or logging to syslog.
  • -v, --verbose β€” verbose mode. Multiple -v flags can be stacked on the command line (e.g., -vvv) to increase verbosity. stack 'em like bracelets ✨
  • --verbose-level β€” level of debugging detail in output. Defaults to the number of --verbose flags specified on the command line, or to 1 if verbose=1 in a stonith device configuration (i.e., on stdin).
  • -D, --debug-file=[debugfile] β€” write debug information to given file
  • -V, --version β€” display version information and exit
  • -h, --help β€” display help and exit
  • --plug-separator=[char] β€” separator for plug parameter when specifying more than 1 plug (Default Value: ,)
  • --delay=[seconds] β€” wait X seconds before fencing is started (Default Value: 0)
  • --disable-timeout=[true/false] β€” disable timeout (true/false) (default: true when run from Pacemaker 2.0+)
  • --login-timeout=[seconds] β€” wait X seconds for cmd prompt after login (Default Value: 5)
  • --port-as-ip β€” make "port/plug" to be an alias to IP address
  • --power-timeout=[seconds] β€” test X seconds for status change after ON/OFF (Default Value: 20)
  • --power-wait=[seconds] β€” wait X seconds after issuing ON/OFF (Default Value: 5)
  • --shell-timeout=[seconds] β€” wait X seconds for cmd prompt after issuing command (Default Value: 3)
  • --stonith-status-sleep=[seconds] β€” sleep X seconds between status calls during a STONITH action (Default Value: 1)
