fence_ipmilan - Fence agent for IPMI over LAN

fence_ilo3 - Fence agent for HP iLO2 (symlink)

fence_idrac - Fence agent for Dell iDRAC (symlink)

Description

fence_ipmilan is an I/O Fencing agent which can be used with machines controlled by IPMI. This agent calls support software using ipmitool (http://ipmitool.sf.net/).

To use fence_ipmilan with HP iLO 3 you have to enable lanplus option (lanplus / -P) and increase wait after operation to 4 seconds (power_wait=4 / -T 4)

fence_ipmilan accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. fence_ipmilan can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.

Parameters for command line

-A
IPMI Lan Auth type (md5, password, or none)
-a
IPMI Lan IP to talk to
-p
Password (if required) to control power on IPMI device
-S
Script to retrieve password (if required)
-P
Use Lanplus
-l
Username/Login (if required) to control power on IPMI device
-o
Operation to perform. Valid operations: on, off, reboot, status, list, diag, monitor or metadata (Default Value: reboot)
-t
Timeout (sec) for IPMI operation
-C
Ciphersuite to use (same as ipmitool -C parameter)
-M
Method to fence (onoff or cycle) (Default Value: onoff)
-T
Wait X seconds after on/off operation (Default Value: 2)
-f
Wait X seconds before fencing is started
-L
Privilege level on IPMI device
-v
Verbose mode
