RE: [Linux-cluster] kernel: CMANsendmsg failed: -101



Well, its actually on a Proliant blade and I'm going in through a
virtual console (an ILO) to issue the ifdown commands.  I'm doing
power-fencing on the ILO itself (its one of the ways you can do it with
Redhat Cluster).

Well normally when a machine is fenced, it is not shut down, just
powered off.  So that would definatly be the problem if the network
interface is still down when you are shutting down the system.  How are
you issuing commands to the servers after taking down the network
interface if you're not on site?

I take it you aren't using power controllers to fence the machines, just
using fence_manual, or an I/O fencing mechanism?

Thanks,
