Note that this bug means that the ipmilan method is unusable in production, as
fence_node doesn't work on those devices.
Comment 6 Adam "mantis" Manthei 2005-08-04 12:19:34 EDT

Note that the error message indicates that you need to specify an option to the
fencing agent.  Just because there is no DEFAULT setting doesn't mean that you
can't use this as a fencing agent or that you can't use it in production.

[root@localhost ~]# cat << EOF | fence_ipmilan 
failed: operation must be 'on', 'off', or 'reboot'

[root@trin-02 ~]# cat << EOF | fence_ipmilan 
ipmilan: ipmitool not found!
failed: Failed to initialize

Unfortunately I don't have access to ipmi hardware at this instant to fully
demonstrate just how one would use this in production, but you should get the

In other words, just add the option that the agent is complaining about missing.
Comment 7 Bastien Nocera 2005-08-04 12:27:24 EDT
"fence_node mymachine" will give you something like that in the syslog:
Fence of "mymachine" was unsuccessful

fence_node is what cman uses, and doesn't pass options to the underlying fence
method. Without the patch above, fence_node is useless for machines using ipmi lan.
Comment 8 Adam "mantis" Manthei 2005-08-04 13:15:33 EDT
"fence_node mymachine" queries ccs which then gets it's info from cluster.conf
and then passes the information to the agent on stdin.  The problem that I am
guessing that you are running into at the moment is that you don't have the
"option" argument specifies in /etc/cluster/cluster.conf.  Adding that option to
the cluster.conf will make the agent work for you.  

The option would look something like this:

                <fencedevice agent="fence_ipmilan" name="ipmi" ipaddr=""
                    passwd="password" login="root" action="reboot" />

Adding "action" will make fence_ipmilan work for your setup :)

don't forget to run ccs_update after modifying it.  You can also try using
system-config-cluster, but I don't know how that will work.
