一、重要知識
ILO2 對應的fence agent是fence_ilo,ILO3,ILO4對應的fence agent是fence_ipmilan。
使用fence_ipmilan agent時，需要節點安裝ipmitool工具，否則報錯：
agent "fence_ipmilan" reports: ipmilan: ipmitool not found! failed: Failed to initialize。
二、fence_ipmilan調試指令
查看主機狀態
fence_ipmilan -P -A password -l cluster -p hpinvent -o status -a 10.10.129.171
三、cluster.conf配置示例
<?xml version="1.0"?>
<cluster config_version="14" name="psql">
<clusternodes>
<clusternode name="trfdb01" nodeid="1">
<fence>
<method name="ilo">
<device name="fence_node1"/>
</method>
</fence>
</clusternode>
<clusternode name="trfdb02" nodeid="2">
<fence>
<method name="ilo">
<device name="fence_node2"/>
</method>
</fence>
</clusternode>
</clusternodes>
<cman expected_votes="1" two_node="1"/>
<fencedevices>
<fencedevice agent="fence_ipmilan" action="off" auth="password" ipaddr="10.10.129.170" lanplus="on" login="cluster" name="fence_node1" passwd="hpinvent"/>
<fencedevice agent="fence_ipmilan" action="off" auth="password" ipaddr="10.10.129.171" lanplus="on" login="cluster" name="fence_node2" passwd="hpinvent"/>
</fencedevices>
