[Linux-cluster] Problems with Cluster

[Robert Gil]

If ilo itself is off, fencing doesn't work. 

Did you add ilo as a fence device? And create a user? You create a user in the ilo for that blade, not on the chassis. You have to reboot the blade to get to the ilo manager.

Isn't there any way which is automated and does not require manual intervention ? Otherwise, the whole purpose gets defeated.
