In an act to solve my fencing issue in my 2 node cluster, i tried to

Here 10.42.21.28 is an IP address assigned to IPMI interface and I am
running this command in the same host.

Sorry couldn't respond earlier as I do this on personal time (which as
useual limited for us IT guys and gals ;-) ) and not during work per
se..

Do not run fence script from the node that you want to fence.

Let us say you want to fence node 3.
1. Try pinging the node 3's IPMI from node 4. I should be successful
2. Issue the fence command from Node 4 with IP of Node 3 IPMI as argument .

With warm regards

Actually, I've recently had this same problem myself.

My second node went to fence the first node and what instead happened was the fence tool hung because the ipmitool hung.

As far as I'm aware this was not always the case - I've been able to fence node01 from node02 before.

Node02 can ping node01's address and it can ping node01's ipmi address as well.

However ipmitool says it can not reach the ipmi address, even though I can manually.

Is anyone else having this issue? Possibly problem with ipmitool perhaps? My boxes are Red Hat 5.2 and were updated via RHN on Friday.

Regards,
