FENCE_AGENT(8)

💖 fence_ibmblade — FENCE_AGENT(8) 💖

okay bestie, so this is fence_ibmblade, a page from the System Manager's Manual (section 8, we love a system administration moment 👑). Buckle up, it's giving power-fencing excellence.

✨ NAME ✨

fence_ibmblade — Fence agent for IBM BladeCenter over SNMP 🎀

---

🌸 DESCRIPTION 🌸

So like, fence_ibmblade is a Power Fencing agent that you use with IBM BladeCenter chassis. What does it do? It sends an SNMP Set request to the BladeCenter chassis and that request either reboots, powers up, or powers down the Blade Server you point it at. Literally the main character of "turn it off and on again." 💅

The fence agent takes options from the command line and from stdin. When fenced execs the agent, it sends parameters through stdin. But here's the slay part: you can also run the agent all by itself with command line options. That's highkey useful for testing, or for turning outlets on/off from your scripts. Obsessed. 🦋

⭐ PARAMETERS ⭐

• -o, --action=[action] — the fencing action you want (Default Value: reboot)
• -c, --community=[community] — set the community string
• -a, --ip=[ip] — IP address or hostname of the fencing device. This parameter is always required, no skipsies 🫶
• -u, --ipport=[port] — TCP/UDP port to use when connecting to the device (Default Value: 161)
• -p, --password=[password] — login password or passphrase 🔐
• -S, --password-script=[script] — script to run to retrieve the password
• -n, --plug=[id] — physical plug number on the device, UUID, or identification of the machine. This parameter is always required too 💀
• -b, --snmp-auth-prot=[prot] — set the authentication protocol (MD5|SHA)
• -P, --snmp-priv-passwd=[pass] — set the privacy protocol password
• -R, --snmp-priv-passwd-script — script to run to retrieve the privacy password
• -B, --snmp-priv-prot=[prot] — set the privacy protocol (DES|AES)
• -E, --snmp-sec-level=[level] — set the security level (noAuthNoPriv|authNoPriv|authPriv)
• -d, --snmp-version=[version] — specifies which SNMP version to use (1|2c|3) (Default Value: 1)
• -l, --username=[name] — login name
• -q, --quiet — disable logging to stderr. Does not affect --verbose, or --debug-file, or logging to syslog. (iykyk, it's specific like that 🙈)
• -v, --verbose — verbose mode. You can stack multiple -v flags on the command line (e.g. -vvv) to crank the verbosity up. the way that compounding works... iconic 🌈
• --verbose-level — level of debugging detail in the output. Defaults to the number of --verbose flags you specified on the command line, or to 1 if verbose=1 in a stonith device configuration (i.e. on stdin).
• -D, --debug-file=[debugfile] — write debug info to the given file
• -V, --version — display version information and exit
• -h, --help — display help and exit
• --plug-separator=[char] — separator for the plug parameter when you're specifying more than 1 plug (Default Value: ,)
• -C, --separator=[char] — separator for the CSV created by the list operation (Default Value: ,)
• --delay=[seconds] — wait X seconds before fencing is started (Default Value: 0)
• --disable-timeout=[true/false] — disable timeout (true/false) (default: true when run from Pacemaker 2.0+)
• --login-timeout=[seconds] — wait X seconds for cmd prompt after login (Default Value: 5)
• --power-timeout=[seconds] — test X seconds for status change after ON/OFF (Default Value: 20)
• --power-wait=[seconds] — wait X seconds after issuing ON/OFF (Default Value: 0)
• --shell-timeout=[seconds] — wait X seconds for cmd prompt after issuing a command (Default Value: 3)
• --stonith-status-sleep=[seconds] — sleep X seconds between status calls during a STONITH action (Default Value: 1)
• --retry-on=[attempts] — count of attempts to retry power on (Default Value: 1)
• --snmpget-path=[path] — path to the snmpget binary (Default Value: /usr/bin/snmpget)
• --snmpset-path=[path] — path to the snmpset binary (Default Value: /usr/bin/snmpset)
• --snmpwalk-path=[path] — path to the snmpwalk binary (Default Value: /usr/bin/snmpwalk)

🎀 ACTIONS 🎀

• on — power on the machine. ✨
• off — power off the machine.
• reboot — reboot the machine. 🔄
• status — this returns the status of the plug/virtual machine.
• list — list available plugs with aliases/virtual machines if there's support for more than one device. Returns N/A otherwise.
• list-status — list available plugs with aliases/virtual machines and their power state, if it can be obtained without additional commands.
• monitor — check the health of the fence device 🩺
• metadata — display the XML metadata describing this resource.
• manpage — the operational behavior of this is not known. (literally a mystery, we respect the enigma 💀)
• validate-all — validate that all required parameters are entered.

🌟 quick vibe check: ip and plug are always required — don't forget them or the whole thing just won't slay. 🫶
