[Linux-cluster] fence_ipmilan fails to reboot

Hi Parvez,

Have you tried method="cycle" ?
(on my cluster I don't specify the auth parameter, but I don't think that's the problem)

Hi all,

I am on RHEL 5.5; and I have two rack mounted servers with IPMI configured.

When I run command from the prompt to reboot the server through fence_ipmilan, it shutsdown the server fine but it fails to power it on

# fence_ipmilan -a <IPMI IP Address> -l admin -p password -o reboot
Rebooting machine @ IPMI:<IPMI IP Address>...Failed

But I can power it on or power off just fine

# fence_ipmilan -a <IPMI IP Address> -l admin -p password -o on
Powering on machine @ IPMI:<IPMI IP Address>...Done

Due to this my fencing is failing and failover is not happening.

I have questions around this -

1. Can we provide action (off or reboot) in cluster.conf for ipmi lan fencing?
2. Is there anything wrong in my configuration? Cluster.conf file is pasted below
3. Is this a known issue which is fixed in newer versions

Here is how my cluster.conf looks like -
<?xml version="1.0"?>
<cluster config_version="4" name="Cluster">
 <fence_daemon post_fail_delay="0" post_join_delay="3"/>
  <clusternode name="blade1.domain" nodeid="1" votes="1">
    <method name="1">
     <device lanplus="" name="IPMI_1"/>
  <clusternode name="blade2.domain" nodeid="2" votes="1">
    <method name="1">
     <device lanplus="" name="IPMI_2"/>
 <cman expected_votes="1" two_node="1"/>
  <fencedevice agent="fence_ipmilan" auth="none" ipaddr="<IMPI 1 IP Address>" login="admin" name="IPMI_1" passwd="password"/>
  <fencedevice agent="fence_ipmilan" auth="none" ipaddr="<IMPI 2 IP Address>" login="admin" name="IPMI_2" passwd="password"/>
   <failoverdomain name="FailoveDomain" ordered="1" restricted="1">
    <failoverdomainnode name="blade1.domain" priority="2"/>
    <failoverdomainnode name="blade2.domain" priority="1"/>
  <service autostart="1" name="service" recovery="relocate"/>
