4.24. IPMI over LAN

The fence agents for IPMI over LAN (fence_ipmilan,) Dell iDRAC (fence_idrac), IBM Integrated Management Module (fence_imm), HP iLO3 devices (fence_ilo3), and HP iLO4 devices (fence_ilo4) share the same implementation. Table 4.25, “IPMI (Intelligent Platform Management Interface) LAN, Dell iDrac, IBM Integrated Management Module, HPiLO3, HPiLO4” lists the fence device parameters used by these agents.

luci Field cluster.conf Attribute Description
Name name A name for the fence device connected to the cluster.
IP Address or Hostname ipaddr The IP address or host name assigned to the device.
Login login The login name of a user capable of issuing power on/off commands to the given port.
Password passwd The password used to authenticate the connection to the port.
Password Script (optional) passwd_script The script that supplies a password for access to the fence device. Using this supersedes the Password parameter.
Authentication Type auth Authentication type: none, password, or MD5.
Use Lanplus lanplus True or 1. If blank, then value is False. It is recommended that you enable Lanplus to improve the security of your connection if your hardware supports it.
Ciphersuite to use cipher The remote server authentication, integrity, and encryption algorithms to use for IPMIv2 lanplus connections.
Privilege level privlvl The privilege level on the device.
IPMI Operation Timeout timeout Timeout in seconds for IPMI operation.
Power Timeout (seconds) power_timeout Number of seconds to continue testing for a status change after issuing a power off or power on command. The default value is 20.
Shell Timeout (seconds) shell_timeout Number of seconds to wait for a command prompt after issuing a command. The default value is 3.
Login Timeout (seconds) login_timeout Number of seconds to wait for a command prompt after login. The default value is 5.
Times to Retry Power On Operation retry_on Number of attempts to retry a power on operation. The default value is 1.
Power Wait (seconds) power_wait Number of seconds to wait after issuing a power off or power on command. The default value is 2 seconds for fence_ipmilan, fence_idrac, fence_imm, and fence_ilo4. The default value is 4 seconds for fence_ilo3.
Delay (optional) delay The number of seconds to wait before fencing is started. The default value is 0.
Method to Fence method The method to fence: on/off or cycle

The following command creates a fence device instance for an IPMI over LAN device:
ccs -f cluster.conf --addfencedev ipmitest1 agent=fence_ipmilan auth=password cipher=3 ipaddr=192.168.0.1 \
 lanplus=on login=root passwd=password123
The following is the cluster.conf entry for the fence_ipmilan device:

 <fencedevices>
  <fencedevice agent="fence_ipmilan" auth="password" cipher="3" ipaddr="192.168.0.1" lanplus="on" login="root" \
   name="ipmitest1" passwd="password123"/>
 </fencedevices>
