Re: [Linux-cluster] Fence Issue on BL 460C G6



I believe your problem is being caused by "nofailback" being set to "1". :

                       <failoverdomain name="Failover" nofailback="1" ordered="0" restricted="0">

Set it to zero and I believe your problem will be resolved.

My guess is there is a problem with fencing.  Are you running fence_ilo with an HP blade?   Iirc the iLOs on the blades have a different CLI, I don't think fence_ilo will work with them.  What do you see in the messages files during these events?  If you see failed fence messages you may want to look into using fence_ipmilan:

http://sources.redhat.com/cluster/wiki/IPMI_FencingConfig

If you post a snip of your messages file from this event and your cluster.conf I will have a better idea of what is going on.
